The National Safety Council, Accident Prevention Manual
for Industrial Operations, Eighth Edition and other recog-
nized safety sources make a common point: Employees
who work near material handling equipment or assist in
hooking on or arranging a load should be instructed in safe
rigging procedures. From a safety standpoint, one factor is
paramount: conduct all pulling operations in such a manner
that if there were an equipment failure, no personnel would
be injured. This means keep out of the line of force of any
load.
Tothe best ofour knowledge,Wintech International
Material Handling winches are manufactured in accordance
with the latest standards in effect at time of manufacture.
However, contrary to common belief, the Occupational
Safety and Health Act of 1970, as we understand it,
generally places the burden of compliance with the user,
not the manufacturer. Many OSHA requirements are not
concerned or connected with the manufactured product but
are, rather, connected with the final installation: “It is the
owner’s responsibility and user’s responsibility to deter-
mine the suitability of a product for any particular use.
Check all applicable industry, trade association, federal,
state and local regulations. Read all operating instructions
and warnings before operation.”
Rigging: It is the responsibility of the operator to exercise
caution, use common sense and be familiar with proper
riggingtechniques. SeeANSI/ASMEB30.9 for rigging
information, AmericanNationalStandards Institute,1430
Broadway,NewYork,NY10018.

does not specifically apply to winches used as barge
pullersor in horizontalpulling applications.
This manual provides important information for all person-
nel involved with the safe installation, operation and proper
maintenance of this product. Even if you feel you are
familiarwith this orsimilar equipment,you must readand

SAFE OPERATING INSTRUCTIONS
winch has a rated capacity equal to or more than the
load. This provides adequate safety in the event of a
sudden load shift or failure of one winch.
10. Never place your hand in the throat area of a hook or in
the vicinity of the wire rope as it spools onto the drum.
11. Position load correctly. Do not attach load on hook
except in a straight pulling line. Do not “side pull” or
“yard”.
12. Keep hands, clothing, etc., clear of moving parts.
13. Do not force a hook into place by hammering.
14. Be certain the load is properly seated in the saddle of
the hook.
15. Do not pull the load on the tip of the hook.
16. Never run the wire rope over a sharp edge. Use a
sheave.
17. Pay attention to the load at all times when operating
the winch.
18. Make sure all people are clear of the loadpath.
19. Never use the winch for lifting or lowering loads and
never allow anyone to stand on a moving load.
20. Ease the slack out of the wire rope when starting a pull.
21. Never weld or cut on a load held by the winch.
22. Do not operate winch ifjamming, overloading,or
binding occurs.
23. After use, properly secure winch and all loads.
24. Always rig loads properly and carefully.
The following warnings and operating instructions have
been adapted in part from American National (Safety)
Standard ANSI B30.7 and are intended to avoid unsafe
operating practices which might lead to personal injury or
property damage.
WintechInternationalrecognizesthatmostcompanies
who use winches have a safety program in force at their
facility. In the event that some conflict exists between a
rule set forth in this publication and a similar rule already
set by an individual company, the more stringent of the two
should take precedence.
Safe Operating Instructions are provided to make an
operator aware of dangerous practices to avoid and are not
necessarilylimited tothe following list. Refer to specific
sections in the manual for additional safety information.
1. Only allow qualified personnel (trained in safety and
operation) to operate and maintain the winch.
2. Only operate a winch if you are physically fit to do so.
3. When a “DO NOT OPERATE” sign is placed on the
winch, do not operate the winch until the sign has
been removed by designated personnel.
4. Before each shift, the operator should inspect the
winchforwear ordamage.
5. Never use a winch which inspection indicates is
defective.
6. Do not use winch if hook latch on a hook has been
sprung or is broken.
7. Only pull loads less than or equal to the rated capacity
of the winch. See warning labels attached to the
winch.
8. Check that the hook latches are engaged before using.
9. When using two winches on one load ensure that each
WARNING TAG
Each winch is supplied from the factory with the warning
tag shown. If the tag is not attached to your winch, order a
new tag and install it. See the parts list for the part
number. Read and obey all warnings and other safety
information attached to this winch. Tag may not be shown
actual size.

Safe Installation Procedures
1. Do not use wire rope as a ground (earth) for welding.
2. Do not attach a welding electrode to winch or wire
rope.
3. Never run the wire rope over a sharp edge. Use a
correctly sized sheave. See instruction 4 under
"MOUNTING".
4. Do not weld to any part of the winch.
5. Always maintain at least three full wraps of wire rope
on the drum.
6. Check gears are lubricated before using winch. See
"LUBRICATION" section.
Prior to installing the winch, carefully inspect it for
possible shipping damage.
Winches are supplied fully lubricated from the factory.
• Owners and users are advised to examine specific,
local or other regulations, including American
National Standards Institute and/or OSHA Regulations
which may apply to a particular type of use of this
product before installing or putting winch to use.
Mounting
1. Mount the winch on a rigid surface which is capable
of supporting the winch and will prevent deflecting or
distortion of the winch under maximum load.
2. Choose a site that uses as short a wire rope as
practical.
• The winch is not a balanced load. Use extreme care
when lifting winch into position.
3. When a lead sheave is used, it should be aligned with
the center of the drum. The diameter of the lead
sheave must be at least 18 times the diameter of the
wire rope.
4. Maintain a fleet angle between the sheave and winch
of no more than 1-1/2 degrees. For every inch ofdrum
length, the lead sheave must be at least 1.6 feet (0.5
m) from the drum.
5. Make sure the mounting surface is flat to within
1/16 in. (1.6 mm). Shim winch if necessary.
6. Position the winch so there is adequate room for the
operator and service personnel to access the winch.
The handwheel rotation must be a full 360 degrees
unobstructed. Reposition winch if necessary.
(Dwg. MHTPA0217)
7. The winch can be mounted using the straight type
deck bracket when welding to a steel deck or the
angle type deck bracket when bolting the winch to the
mounting surface.

Wire Rope
• Maintain at least 3 wraps of wire rope on the drum at
all times.
• Install the wire rope to come off the drum in an
underwind position.
Wire Rope Selection
Consult a reputable wire rope manufacturer or distributor
for assistance in selecting the appropriate type and size of
wire rope and, where necessary, a protective coating. Use
a wire rope which provides an adequate safety factor to
handle the actual working load and meets all applicable
industry, trade association, federal, state and local
regulations.
When considering wire rope requirements the actual
working load must include not only the static or dead load
but also loads resulting from acceleration, retardation and
shock load. Consideration must also be given to the size
of the winch wire rope drum, sheaves and method of
reeving.
• Check wire rope diameter provides adequate safety
factor.

in. (mm) in. (mm)
25 ton 5/8 16 1 26
50 ton 7/8 22 1-1/4 32
The maximum wire rope diameter is limited by the size of
the wire rope anchor hole.
Installing Wire Rope
• Position the wire rope so that it comes off the bottom
of the drum (underwind).
1. Cut wire rope to length and fuse end to prevent
fraying of strands in accordance with the wire rope
manufacturer's instructions.
2. Feed the fused end of the wire rope into the wire rope
anchor hole. Position the end of the wire rope just
beneath the drum surface. (See Dwg. MHTPA0218)
3. Make sure the wire rope wedge is the correct size for
the wire rope.
4. Install the wire rope wedge into anchor hole. Install
the wedge from the side of the hole with the wire rope
end. Position the wedge so the serrated surface is on
the wire rope. Insert the narrow end of the wedge
first. The wedge must be positioned so it is nearer the
surface of the drum.
(Dwg. MHTPA0218)
5. Hammer the wedge into the wire rope anchor hole to
secure the wire rope.
6. While keeping the wire rope under tension, wind the
wire rope onto the drum.
• Make sure the first wrap of wire rope is flush against
the drum flange.
Wire Rope Spooling
To allow for uneven spooling and decrease in line pull
capacity as the drum fills up, use as short a wire rope as
practical. To rewind wire rope apply tension to eliminate
slack. This helps achieve level winding and tight spool-
ing
Rigging
Make sure all wire rope blocks, tackle and fasteners have
sufficient safety margin to handle the required load. Do
not allow wire rope to contact sharp edges or make sharp
bends which will cause damage to wire rope, use a sheave.
Refer to wire rope manufacturer's handbook for proper
sizing, use and care of wire rope.
Safe Wire Rope Handling Procedures
1. Always use gloves when handling wire rope.
2. Never use wire rope which is twisted, frayed or
kinked.
3. Never use wire rope as a sling.
4. Always ensure wire rope is correctly spooled and first
layer is tight.
Wiring
Be sure phase, cycle and voltage of motor, magnetic
reversing starter and controls all match the electrical
service being used. Check power supply is correctly
grounded. All electrical connections must be properly
insulated and enclosed.

• Never use a 230V motor with a 115V power supply.
The motor can be permanently damaged.
• Switches and starter enclosures must be grounded to
electrical supply system.
Power supply voltage must be within 4%. For 460V
motor, the power supply should be greater than 442V and
must not exceed 478V. For a 230V motor, the power
supply should be greater than 221V and not exceed 239V.
Brake Connections
Brake power connections depend on winch power voltage
and brake operating voltage. Drawings MHTPA0247 and
MHTPA0249 show the three possible combinations for
230/460V motors. See drawing MHTPA0198 for location
of brake power connection lines.
(Dwg. MHTPA0247)
(Dwg. MHTPA0249)
Controls
A momentary contact reversing drum switch is recom-
mended for the winch control unless remote or automatic
control of the winch is required. Refer to parts section for
recommended switches. See Wiring Diagram Dwg.
MHTPA0201 for three phase motors.
If remote or automatic control is required, an electromag-
netic reversing starter is recommended. The starter can be
used with either a hand held pendant or with a wall
mounted control station. Automatic control depends on
application. Refer to wiring diagrams for winches using
starters. For three phase motors see Dwg. MHTPA0198.
Contact your nearest distributor or the factory for recom-
mendations on specific applications.

The four most important aspects of winch operation are:
1. Follow all safety instructions when operating the
winch.
2. Allow only qualified people to operate the winch.
3. Subject each winch to a regular inspection and main-
tenance procedure.
4. Be aware of the winch capacity and weight of load at
all times.
• Only allow qualified personnel (trained in safety and
operation) to operate a winch.
• To avoid damage to the rigging, the structure sup-
porting the rigging, and the winch, do not “two-block”
the end of the wire rope.
Power Operation
• A creeping load can cause death or injury. Do not
rely on the gear reduction or brake to hold a load.
• Operating winch for time periods longer than sug-
gested may result in damage to the motor.
The motor on the winch has a intermittent duty rating of
15 minutes. This is the number of minutes the motor may
be operated during a one hour period when the winch is
carrying the full rated load.
When operating the winch avoid unnecessary jogging of
the controls.
OPERATION
Free Spool
• Never disengage the dog with tension on the wire rope
or if the drum is moving.
To disengage the dog (free spool) pull out spring loaded
plunger pin and rotate until plunger pin tab is clear of dog
lever. Dog lever will pivot to the lower position. Release
plunger pin to engage over the dog lever.
To engage the dog pull out spring loaded plunger pin and
rotate until plunger pin tab is clear of dog lever . Lift dog
lever to engage dog. Release plunger pin to engage under
the dog lever.
Hand Wheel Operation
A 28 in. (71 cm) diameter handwheel is available as an
option with the winch. Install the handwheel on the
square end of the power drive assembly and clamp into
position with setscrews.
• To avoid injury to personnel and damage to equip-
ment due to handle flying off while winch is operating,
remove handwheel before operating winch with motor.
In the event of a power failure the hand wheel can be used
to take-up wire rope after the wire rope has been con-
nected to the load. Place holding dog release lever in the
up position to engage the holding dog, take up the slack
with the handwheel while making sure the wire rope is
being uniformly spooled onto the drum. Tensioning may
be accomplished with the handwheel by firmly grasping
the rim of the handwheel with two hands and rotating.

c. Wear of crown wires. Replace at 1/3 wear of the
original diameter of any crown wire.
d. Broken wires or strands, particularly at connec-
tions. Replacement is necessary if one wire is
broken at a connection; six broken wires within
one lay; three broken wires in one strand within
one lay.
4. WIRE ROPE REEVING. Check reeving and ensure
wire rope is properly secured to the drum.
5. LUBRICATION. See "LUBRICATION" section for
recommended procedures.
Periodic Inspection
According to ANSI/ASME B30.7, frequency of periodic
inspection depends on the severity of usage: NORMAL,
yearly; HEAVY, semi-annually; SEVERE, quarterly.
Disassembly may be required for HEAVY or SEVERE
usage. Keep accumulative records of periodic inspections
to provide a basis for continuing evaluation. Inspect all
items in “Frequent Inspection” also inspect the following:
1. MEMBERS. Check for deformed, cracked or corroded
main components. Replace damaged parts if neces-
sary.
2. FASTENERS. Check rivets, cotter pins, capscrews
and nuts on winch, including mounting bolts. Replace
if missing and tighten if loose.
3. DRUM. Check for cracks, wear or damage. Replace if
necessary.
4. ALL COMPONENTS. Inspect for wear, damage,
distortion and cleanliness. If external evidence
indicates the need, for example poor performance or
excessive noise, disassemble and inspect. Check pins,
gears, shafts, bearings, sheaves, covers, etc. Replace
worn or damaged parts.
5. MOTOR. Make sure it operates properly and con-
forms to applicable specifications. Check wiring
connections are clean, dry and secure.
6. BRAKE. Inspect the brake lining after every 50 hours
of use. When any part of the lining on either brake
shoe measures 1/16 in. (2 mm) or less, the brake
shoes should be replaced.
7. SUPPORTING STRUCTURE. Check for distortion,
wear and continued ability to support the winch and
load.
8. LABELS AND TAGS. Check for presence and
legibility. Replace if necessary.
9. ELECTRICAL COMPONENTS. Check for loose
wires, corrosion or other signs of deterioration.
10. DRIVE CHAIN. Check for excessive wear of chain
drive sprockets and for chain stretch. Check chain for
elongation. Lay the used chain on a flat surface and
using a caliper-type gage, check the dimension from
the edge of one chain pin to the corresponding edge of
another pin for the number of pitches per foot. If
elongation exceeds 1/4 in. (6.3 mm) in 12 in.
INSPECTION
There are two types of inspection, the frequent inspection
performed by the operator and more thorough periodic
inspections performed by qualified personnel. Careful
inspection on a regular basis will reveal potentially
dangerous conditions while still in the early stages,
allowing corrective action to be taken before the condition
becomes dangerous.
Any deficiency revealed through inspection must be
reported to an appointed person. A determination must be
made as to whether a deficiency constitutes a safety hazard
before resuming operation of the winch.
Records and Reports
Some form of inspection record should be maintained for
each winch, listing all points requiring periodic inspec-
tion. A written report should be made monthly on the
condition of the critical parts of each winch. These reports
should be dated, signed by the person who performed the
inspection, and kept on file where they are readily
available to authorized personnel.
• Never use a winch that inspection indicates is defective.
Frequent Inspection
On winches in continuous service, frequent inspection
should be made at the beginning of each shift. In addition,
visual observations should be conducted during regular
service for any damage or evidence of malfunction.
1. OPERATION. Check for visual signs or abnormal
noises which could indicate a defect. Do not operate
a winch unless the wire rope feeds onto the winch
drum smoothly. If wire rope binds or jumps, clean
and lubricate the wire rope. If problem persists,
check wire rope fleet angle as described in the
"INSTALLATION" section or replace the wire rope.
Make sure the drive mechanism operates properly,
check for sticking or other signs of malfunction.
Repair if necessary. Do not operate the winch until
all defects have been corrected. To test brake, apply a
pull to the end of the wire rope and check that the
brake does not slip.
2. LIMIT DEVICES. If used, check that they operate
properly.
3. WIRE ROPE. Lubricate if necessary. Replace the wire
rope if damaged or excessively worn. Consult the wire
rope manufacturer’s inspection information or a
recognized safety source, such as the latest edition of
National Safety Council, Accident Prevention Manual
for Industrial Operations or ANSI/ASME B30.7. At a
minimum, visually inspect for the following and
replace if necessary:
a. Damage, such as: bird cages, kinking, core
protrusion, crushing, heat damage, and main
strand displacement.
WARNING

12
(305 mm) the chain shall be replaced. For example, a
3/4 in. (19 mm) pitch chain should measure 12 in.
(305 mm) over 16 pitches. Chain shall be rejected if
measurement over 16 pitches exceeds 12-1/4 in.
(311 mm).
11. WIRE ROPE.
Besides the items in a frequent inspection, inspect for
the following:
a. Build-up of dirt and corrosion. Clean if
necessary.
b. Loose or damaged end connection. Replace if
loose or damaged.
c. Check wire rope anchor is secure.
d. Changes in the size of the wire rope diameter.
Periodically measure the diameter of the wire
rope from crown-to-crown throughout the life of
the wire rope. The actual diameter should be
recorded when the wire rope is under equivalent
loading and in the same operating section. If the
actual diameter of the wire rope has decreased
more than 1/64 in. (0.4 mm) a through examina-
tion of the wire rope should be conducted by an
experienced inspector to determine the suitability
of the wire rope to remain in service. (see Dwg.
MHTPA0056).
(MHTPA0056)
Winches Not in Regular Use
A winch which has been idle for a period of one month or
more, but less than six months, shall be given an inspec-
tion conforming with the requirements of "Frequent
Inspection" before being placed into service.
A winch which has been idle for a period of over six
months shall be given a complete inspection conforming
with the requirements of "Periodic Inspection". Standby
winches shall be inspected at least semi-annually in
accordance with the requirements of "Frequent Inspec-
tion". If abnormal operating conditions apply winches
may require a more frequent inspection.
Testing
Operational Tests
Prior to initial use, all new, altered or repaired winches
shall be tested to ensure proper operation.
a) Operate winch in both directions with no load.
b) Check operation of brake, and holding dog.
c) Check operation of limit switches, and locking or
safety devices when provided.
d) Check all tie-downs are secure.
Load Test
Prior to initial use, all new, extensively repaired, or
altered winches shall be load tested by or under the
direction of a qualified person, and a written report
furnished confirming the rating of the winch. Test loads
shall not be more than 110% of the rated line pull.

Lubricate grease fittings, chain and wire rope monthly. The
lubrication intervals are based on intermittent operation of
the winch eight hours each day, five days per week. If the
winch is operated almost continuously or more than the
eight hours each day, more frequent lubrication will be
required. Also, the lubrication types are based on opera-
tion in an environment relatively free of dust, moisture, and
corrosive fumes. Use only those lubricants recommended.
Other lubricants may affect the performance of the winch.
Approval for the use of other lubricants must be obtained
from Wintech International or your nearest distributor.
Failure to observe this precaution may result in damage to
the winch and/or its associated components.
Bushings and Pivot Points
Lubricate all grease fittings monthly with 2 or 3 pumps from
a grease gun, or more frequently, depending on severity of
service. Rotate components slowly as grease is applied.
If the winch is disassembled, clean all parts thoroughly and
coat bushings and shafts with clean grease. Use sufficient
grease to provide a good protective coat. For temperatures
-20° to 50° F (-29° to 10° C) use a multipurpose lithium-
based EP 1 grease. For temperatures 30° to 120° F (0° to 49°
C) use a multipurpose lithium-based EP 2 grease.
Gears
Lubricate working surfaces of all gear teeth. Brush with
grease as often as necessary to keep teeth liberally
covered. If grease becomes contaminated with sand, dirt or
other abrasive materials clean off old grease and relubricate.
Use the same grease that is recommended for the bushings
and pivot points.
DriveChain
Roller chains must be kept clean and free from rust.
Excessively dirty chains should be soaked in a clean acid-
free solvent. Chains must be agitated in the solvent to
ensure that all joints are free from grit and foreign matter.
Lubricate roller chain with a good quality automotive motor
oil SAE grade 20 or 30. DO NOT USE GREASE. Oil should
be applied liberally with a brush or oil can at least once
every eight hours of operation.
• Do not lubricate chain while winch is running. Shut off
power to the winch during all maintenance operations.
Motor
No lubrication required.
Wire Rope
Follow the wire rope manufacturer’s instructions. At a
minimum, observe the following guidelines.
1. Clean with a brush or steam if there is dirt, rock dust or
other foreign material on the surface of the rope.
• Do not use an acid-based solvent. Only use cleaning fluids
specified by the wire rope manufacturer.
2. Apply a wire rope lubricant or SAE 30W oil.
3. Brush, drip or spray lubricant weekly, or more
frequently, depending on severity of service.

• Before performing maintenance, disconnect the load
from the winch. A falling load could cause death,
injury or property damage.
• Disconnect electrical power source before performing
any maintenance. Accidental operation or contact with
exposed power supply could cause death, injury or
property damage.
• Before starting maintenance, tag winch: DANGER -
DO NOT OPERATE - EQUIPMENT BEING RE-
PAIRED.
• Only allow qualified service personnel to perform
maintenance.
• After performing maintenance on load bearing parts,
test unit to 110% of its rated capacity before returning
to service.
Brake Adjustment
• Allow brake to cool before adjusting.
If the brake lining and brake solenoid are satisfactory,
then check brake adjustment as follows:
1. Raise brake lever (53) to the top of its stroke and
hold.
2. Adjust nut (40) on adjustment stud (39) until top of
nut is flush with the end of the adjustment stud (39).
Brake shoes (44) and (45) must be free of the brake
drum diameter. Brake lever (53) should be located in
the upper part of the adjustment range.
(Dwg. MHTPA0259)
3. Operate winch with no load while gradually tighten-
ing nut (40) to make adjustment.
4. Brake should be correctly adjusted when brake lever
(53) is parallel to the ground and plunger (29) is
1/2 in. (13 mm) clear of the motor base (7).
5. Check brake for ability to stop drum rotation by
pushing down on the brake lever.
Adjustment Label (25 ton winch)
If brake lever falls out of adjustment range (see adjustment
label) or fails to stop drum rotation recheck adjustment
and position of anchor eccentric (47). If brake does not
stop drum rotation brake shoes may be worn or distorted
and require replacement.
• Do not allow plunger (29) to contact the motor base.
Chain Adjustment
Check the condition of the chain per instructions in the
"INSPECTION" section. Check the chain adjustment as
follows:
1. Place a straight edge on top of the chain (62)
bridging the two chain sprockets.
2. Place a measuring rule on the top of the chain
midpoint between the two chain sprockets. Apply an
inward force perpendicular to the chain. Proper chain
tension is 3/8 in. (10 mm) on the rule.
3. To increase chain tension, loosen motor adapter plate
nuts (12), adjust nuts (12) to increase height of motor
adapter plate (3) and re-tighten nuts (12). Repeat if
necessary until proper chain tension is attained.
General Disassembly
The following instructions provide the necessary informa-
tion to disassemble, inspect, repair, and assemble the
winch. An exploded drawing of the winch is provided in
the Parts Section to assist part indentification. If a winch
is being completely disassembled for any reason, follow
the order of the topics as they are presented. It is recom-
mended that all maintenance work on the winch be
performed in a clean dust free work area.
In the process of disassembling the winch, observe the
following:
1. Never disassemble the winch any further than is
necessary to accomplish the needed repair. A good
part can be damaged during the course of disassem-
bly.

Cleaning, Inspection and Repair
Use the following procedures to clean, inspect, and repair
the components of the winch.
Cleaning
Clean all winch component parts in solvent (except for the
brake shoe). The use of a stiff bristle brush will facilitate
the removal of accumulated dirt and sediments on the
gears, frames and drum. If bushings have been removed it
maybe necessary to carefully scrape old Loctite from the
bushing bores. Dry each part using low pressure, filtered

16
compressed air. Clean the brake shoe using a wire brush or
emery cloth. Do not wash the brake shoe in liquid. If the
brake shoe lining is oil soaked, it must be replaced.
Inspection
• Bushings that are loose, worn or rotate in the frame,
gears or drum must be replaced. Failure to observe this
precaution will result in additional component damage.
(See Bushing Chart).
All disassembled parts should be inspected to determine
their fitness for continued use. Pay particular attention to
the following:
1. Inspect all gears for worn, cracked, or broken teeth.
2. Inspect all bushings for wear, scoring, or galling.
Bushing Chart
25 ton winch
50 ton winches
3. Inspect shafts for ridges caused by wear. If ridges
caused by wear are apparent on shafts, replace the
shaft.
4. Inspect all threaded items and replace those having
damaged threads.
5. Inspect the brake shoe lining for oil. If the brake shoe
lining is oil-soaked, replace the brake shoe. If the
brake shoe is glazed, sand it lightly using fine emery
cloth.
6. Measure the thickness of the brake shoe lining. If the
brake shoe lining is less than .062 in. (2 mm) at any
point along its edge replace the brake shoe (45).
Repair
Actual repairs are limited to the removal of small burrs
and other minor surface imperfections from gears and
shafts. Use a fine stone or emery cloth for this work.
1. Worn or damaged parts must be replaced. Refer to the
applicable Parts Listing for specific replacement parts
information.
2. Inspect all remaining parts for evidence of damage.
Replace or repair any part which is in questionable
condition. The cost of the part is often minor in
comparison with the cost of redoing the job.
3. Smooth out all nicks, burrs, or galled spots on shafts,
bores, pins, or bushings.
4. Examine all gear teeth carefully, and remove nicks or
burrs.
5. Polish the edges of all shaft shoulders to remove small
nicks which may have been caused during handling.
6. Remove all nicks and burrs caused by lockwashers.
Winch Assembly
1. Position side frames (76) and (101) in a vertical
position with a temporary brace.
2. Install spacer shafts (64) and (85) on side frame (76)
