AIR WINCHES

FOR TOP PERFORMANCE AND MAXIMUM DURA-
BILITY OF PARTS, OPERATE THIS WINCH AT 90 psig
(6.2 bar/620 kPa) AIR PRESSURE WITH 1-1/4” (32 mm)
DIAMETER HOSE.
OPERATING PRACTICES
The two most important aspectsof Winch operation are:
(1) Allow only qualified people to operate aWinch and (2)
Subject each Winch to a regular inspection and maintenance
procedure.
A qualified operator must be physically competent. He
must have no health condition which might affect his
ability to react, and he must have good hearing, vision and
depth perception. The qualified Winch operator must be
carefully instructed in his duties and must understand the
operation of the Winch, including a study of the manufac-
turer’s literature. He must thoroughly understand proper
methods of hitching loads. He should have a good attitude
regarding safety and should refuse to operate under unsafe
conditions.
Regular inspection procedures should be set up, rigidly
adhered to and recorded by or under direction of a quali-
fied person. On Winches in continuous service, inspection
should be made at the beginning of each shift. The items to
be

checked include, but are not limited to:
LUBRICATION: SeeLUBRICATION on Pages4 and 5.
BRAKES: Visually check for proper adjustment.
Lift a capacity or near capacity load a few inches off the
floor and check ability of braking system to stop and
hold the load without excessivedrift.
WIRE ROPE AND HOOKS: Visually inspect the wire-
rope. Replace it AT ONCE if there is indication of fray-
ing, or if it is crushed, cut or otherwise damaged.Follow
cable manufacturer’s recommended practice for proper
use and inspection of wire rope.
Hooks should be checked for wear, increase in throat
opening, and bending.
CONTROLS: See that controls function properly and
return to neutral when released.
GENERAL: Check to see that mounting fastenings are
secure, unworn and undamaged. Be alert for unusual
visual or audible signs which could indicate a defect. Do
not operate the Winch until the defect has been deter-
mined and corrected.
a. Periodically, depending on the severity of the service:
Inspect Brake and Locking Dog components for wear or
damage.
b. Check all bolts or fasteners.
C.
Inspect the Winch structure for damage.
Notice: The use of other than genuine Ingersoll-Rand
replacement parts may result in decreasedWinch perform-
ance and increased maintenance, and may invalidate all
warranties.

tures, and do not apply sudden loads to a cold chain.
LUBRICATION
Warning: Lubricate the motor before using the Winch.
To avoid leakage during shipment, the oil was drained from
the motor. A quantity of oil sufficient for one filling is con-
tained in the can packed with the Winch. Before using the
Winch, make certain the three Plugs (2 and 3) are securely
threaded into place. Unscrew the Vent Cap (4) and pour
the entire contents of the can into the opening in the top
of the Motor Case(1).
Motor Lubrication
Check oil daily and maintain level with opening in the
side of the Motor Case.
When the Winch is subjected to temperatures above
32° F (0° C): After the Winch has been idle for several
hours or overnight, loosen the Drain Plug (2) located at
the bottom of the Motor Case(1) and allow the accumu-
lated water to drain out. After draining the water, tighten
the Plug in the bottom and remove a similar Plug on the
side of the Motor Case. Unscrew the Vent Cap (4) and
pour a sufficient quantity of the recommended oil through
the opening to bring the oil level up to the side opening.
Replace the Plug and Vent Cap.
When the Winch is subjected to temperatures below 32°
F (0”): Allow the Winch to remain idle long enough for the
water content in the Motor Case(1) to separate from the
oil, but not long enough for it to freeze. Drain the water
and replenish the oil as above. Should this procedure be
impractical, drain the entire contents from the Motor Case
immediately after operation ceases,and pour the oil back
into the Motor Case before resuming operation. If not
drained, a sufficient quantity of water will eventually ac-
cumulate so that the Oil Splasher (37), which is attached
to the Crank (36) will freeze fast.
For temperatures 30° to 80° F (-1° C to 26° C) use
Ingersoll-Rand Medium Oil No, 50 or SAE 20 or 20WMo-
tor Oil.

LUBRICATION (Continued)
For temperaturesbelow 30° F (-1° C) useSAE 10 or
1OWMotor Oil.
For temperatures above 80° F (26° C) use SAE 30
Motor Oil.
Throttle Valve Lubrication
Weekly, insert a small quantity of Ingersoll-Rand Light
Grease No. 28 or a good quality No. 2 cup greaseinto the
Grease Fittings (14) located in the Valve Chest (10). Two
or three strokes from the No. P25-228 Grease Gun is an
ample for each Fitting.
Gearing Lubrication
Every sixty to ninety days, remove the Grease Plug
(108) from the Gear Case(84) and note if the visible por-
tion of the gearsis coated with grease.If the gearsappear
to lack lubrication, add approximately l/2 pint (240 mL)
of the recommended grease. When reassembling a Winch,
approximately two pounds (1 kg) of grease is required.
Use Ingersoll-Rand Heavy Gear Grease No. 70. As a
substitute, Ingersoll-Rand Light Grease No. 28 or a good
quality No.2 cup greasemay be used.
For extremely low temperatures, Ingersoll-Rand Medium
Gear Grease No. 75, low temperature greaseor a heavy gear
oil may be used. Note: Leakage will probably be experi-
enced if heavy gear oil is used for normal temperatures.
Lubricate the Drum Gear occasionally by pushing a
piece of hard stick or block grease3/4” to 1” (19 mm to 25
mm) long through the hole above the Drum Shaft Long Set-
screw (7.5).
Air Line Lubricators are recommended for use with
Utility Winches. Their use will improve the efficiency and
prolong the life of the motor.
HOSE AND HOSE CONNECTIONS
Use l-1/4” (32 mm) hose with a suitable hose fitting for
attaching it to the inlet. Useof smaller hose and fittings will
reduce the efficiency of the Winch.
MOUNTING
Mount the Winch so that the axis of the Rope Drum (67)
is horizontal. Operation of the Winch with the axis of the
Drum more than 10° from horizontal will result in lubrica-
tion difficulties and the Wire Rope will tend to pile up on
the low end of the Drum.
5

MOUNTING (Continued)
On all Winches with four-cylinder motors, the Motor
Case (1) can be rotated on the Motor Mounting Bracket
(66) to any one of eight different positions. When aWinch
is shipped from the factory, the Motor Caseis positioned
for operation when the Winch is mounted upright on its
base. Therefore, the Motor Casemust be repositioned on a
Winch which is to be mounted in such a way that the Vent
Cap (4) is more than 25° off top vertical center.
To change the position of the Motor Case:
1. Drain the oil.
2. Unscrew the eight Motor CaseScrews(57).
3. Rotate the Motor Caseto bring the Vent Cap asnear
top vertical center aspossible.
4. Replace the Cap Screws.
5. Fill with oil.
On H5U and HSUL Winches, the Motor Case can be
rotated to any one of five different positions. The Motor
Casemust be repositioned on either of these sizeswhen the
Winch is to be mounted in such a way that the Drain Plug
(2) is more than 25° off bottom vertical center. To change
the position of the Motor Case:
1. Drain the oil.
2. Unscrew the ten Motor CaseScrews(57).
3. Rotate the Motor Case to bring the Vent Cap asnear
bottom vertical center aspossible.
4. Replace the Cap Screws.
5. Fill with oil.
The Winch should not be operated in such a position
that one of the Cylinders (48) is directly at the bottom.
MAINTENANCE
Apply the Wire Rope to wind on the Rope Drum in the
direction indicated by the instruction plate on the Winch.
Adjust the brake on Winches over serial 14 000 so that
considerable pressure is required to push the Brake Handle
(126) past center for locking. Make adjustment by remov-
ing the Brake Shoe Long Pin (131) and rotating the Brake
Adjusting Screw (130).
Remove the Throttle Valve Spring (21), Poppet Throttle
Valve (20) and Throttle Valve Ball (22) from the Valve
Chest (10) before attempting to withdraw the Reverse
Valve (24) from the ReverseValve Bushing (13).

(24) and remove the Throttle Lever Spring (35).
Support the face of the Valve Chest(10) that contacts
the Motor Case (1) and press out the two Bushings
with an arbor that will clear the Bushing Keys (11).
Caution: Failure to use an arbor that will clear the
Bushing Keys, or pressing the Bushings in the oppo-
site direction than instructed, will destroy the Keys.
Support the face of the Valve Chest (10) that con-
tacts the Valve Chest Cover (17); align the keyslot in
the new Reverse Valve Bushing with the Bushing Key
(11), and press the Bushing into the Chest until the
leading face of the Bushing is flush with the sup-
ported face of the Chest. Align the keyslot in the
new Rotary Valve Bushing with the Bushing Key
and pressthe Bushing into the Chest until the bushing
shoulder is flush with the supported face of the
Chest.
Insert the No. 23470 Throttle Valve Stem Reamer or
a .505” (12.8 mm) hand reamer through the throttle
valve chamber in the Valve Chest and ream the hole
through the wall of the new Reverse Valve Bushing.
Check the fit of the Rotary Valve (25) in the new
Rotary Valve Bushing. If the Valve is tighter than a
good running fit in the Bushing, lap in the Valve,
using a fine grain lapping compound whose abrasive
agent will break up rapidly. Remove all trace of the
compound after obtaining the desired fit.
Check the fit of the Reverse Valve (24) in the new
ReverseValve Bushing. If the tit is too tight, ream the
Bushing asfollows:
1.750” (44.4 mm) for four-cylinder motors.
1.875” (47.6 mm) for five-cylinder motors.
Caution: The Reverse Valve is chrome-plated; do not
lap.

the Case. Place a hardwood block on the chest face
and press or drive in the Bushing until the Valve
Chest contacts the Motor Case.
The two sections of the Crank (36) are matched before
final machining, and the web of each section is stamped
with an identification mark as AA17, CC21, Xx19, etc.
Only sections bearing identical marking can be used toge-
ther. If more than one Crank is disassembled at one time,
be sure only matched parts are assembledtogether.
Slide the Crank Pin Sleeve(39), plain end first, onto the
crank pin when assembling the Crank (36).
Install the Connecting Rod Rings (44) so that the inter-
nally beveled ends are toward the Connecting Rods (43)
when assembling the Crank (36).
