1. General Information
The Level Wind is a chain driven device specifically designed to distribute wire rope coils or
wraps evenly across the winch drum.
Level winding the wire rope onto the drum has several advantages:
● Increases drum storage capacity.
● Prevents wire rope pileup.
● Permits smooth, steady pulls.
● Establishes tight, even wraps preventing the wire rope from cutting down through the lower
lays resulting in damage to the rope and difficulty in unwinding.
2. Description
The level wind assembly includes a carriage/roller cage, guide bars, speed reducer, two single
width and one triple width roller chain drive.
The carriage is mounted on two guide bars and is driven side to side across the drum by an end-
less triple width cross chain (See Figure 1 on page 2).
The carriage is connected to the cross chain by a drive pin which projects into a vertical slot in
the carriage. As the cross chain rotates, it carries the drive pin and the carriage across the drum.
When the drive pin reaches the end sprocket, it rotates around the sprocket moving up or down
in the slot as required. Accordingly, the carriage and wire rope moves to the end of its travel and
starts back again across the drum.
Positioned above the carriage (or below in the under wind configuration) is the roller cage as-
sembly thru which the wire rope passes for final storage on the drum. The rollers are shielded
with a roller guard for the purpose of operational safety.
3. Operation
The level wind is mechanically driven from the motion of the winch drum. Use caution to maintain
uniformity and compactness of the wraps and lays of the wire rope on the drum at the start of the
pull.
The carriage remains properly aligned because the level wind is mechanically driven directly
from the winch drum. This is true of whether the rope is paying onto the drum under power or
paying out under free spool conditions.
The speed of the carriage is regulated. For each revolution of the winch drum, the carriage ad-
vances across the drum a distance equal to the diameter of the rope.
Initially, the correct sprockets are determined by the factory relative to the nominal cable size
that is specified for the winch. Due to minor variations in the diameter of the wire rope, the aver-
age diameter may have to be determined in order to modify the speed of the rope winder. Take
several diameter measurements along the length of the wire rope, and call GMP to determine
the correct sprocket combination.
Once a given set of sprockets has been established for a specific wire rope diameter, the rope
diameter cannot be changed without a change in the sprocket teeth combination.
Constant tension must be maintained on the rope when operating the level wind. The
amount of tension should be sufficient to eliminate “clock springing” that will lead to loose or tan-
gled wraps and lays.
Under free spool conditions, if the drum has been permitted to over-run, resulting in loose or tan-

gled wraps, remove several feet of improperly wrapped rope and rewind, under tension, prior to
starting the actual pull. To insure good operation, the wraps and lays must always be straight
and compact.
The winch is furnished with a caliper type drag brake. The brake is not designed to hold the load.
The purpose of the brake is to control the drum rotation speed when paying out wire rope under
free spool conditions. Slowing down and gradually stopping the drum, with tension on the rope,
will prevent backlash, clock-springing and eventual entanglement of the rope.
For safety and convenience, the drag brake is equipped with a remote actuator. The remote ac-
tuator, reservoir and flexible hose section are shipped loose in the parts box. These components
are to be installed by the dealer.
Although the level wind will guide the wire rope onto the drum from a relatively wide fleet angle,
there will be less bending of the rope at the roller cage assembly if the line of pull is as straight
as possible. Therefore, the use of a universal or universal swivel sheave on the tail shelf is advis-
able.
The roller cage assembly has only a sufficient amount of clearance for the rope to pass. When
pulling in the wire rope, it is important that the operator stops the drum rotation at a point to keep
the spliced eye or quick hook several feet from the roller cage. Otherwise, the eye and hook will
be drawn into the roller cage, causing damage to the level wind.
If, for any reason, it is necessary to remove the wire rope from the roller cage while at a mid-
point in the rope, it can be done by removing the roller cage top plate. First, remove the (2) hex
bolts on the roller cage top plate then remove the top plate. Loosen the (2) set screws on either
side of the mounting plate and remove the roller guide. The rope is then free.
4. Placing Wire Rope Onto The Winch Drum
Note: See section 8.0 for additional details on wire rope.
The timing of the level wind must be set properly when placing rope onto the drum. Set the tim-
ing of the level wind by rotating the drum until the carriage reaches a position of maximum travel
at the drum end where the rope is to be attached. The extreme end of the carriage travel is when
the guide link is on the outside of the end sprocket and at the mid-point of the vertical slot in the
carriage. Thread the end of the rope through the roller cage and attach it to the drum by means
of the rope clamp. See figure 2. Drive the winch forward at a low speed, keeping sufficient ten-
sion on the rope. It is extremely important that the first lay of rope be straight and compact. Slow-
ly increase the drum speed and spool on the remaining rope.
Whenever possible, a winch line holder should be used to prevent the rope from unwinding.

output single width roller chain drives should be tight enough to prevent backlash but not exces-
sively tight to cause bending of the reducer shafts. Special care should be taken when adjusting the
first reduction chain. Rotate the drum (with the chain loose), to the point where the chain is at its
tightest (its high spot). Adjust the chain idler to about 1/2 inch deflection in the chain. Next, rotate
the drum a full turn to insure that the chain doesn’t get tighter than the 1/2 in. deflection. A 1st re-
duction chain that’s too tight will permanently bend the input shaft.
The triple width cross chain should be sufficiently tight to prevent tipping of the guide link. Any un-
steady movement of the carriage could indicate a loose cross chain or lack of lubrication on the
guide bars.
The cross chain should be adjusted an equal amount at both ends by the corresponding adjusting
screw. The distance from the back of the chain to the inside of the drum must be equally spaced.
See Figure 3.
The front chain drive (2nd reduction) from the speed reducer must be loosened before
any adjustment is made to the cross chain.
Rotate the drum one revolution taking a measurement at four locations to check for equal spacing.
Checking in four locations will compensate for any distortion in the drum flanges. Shift the cross
chain assembly by turning the adjusting screws at each end after the lock nuts have been loosened.
If the rope piles up at one end and leaves an opening at the other end, shift the cross chain slightly
away from the end where the rope piles up
The cross chain length is for an average drum width. If the rope piles up at both ends of the drum,
the cross travel speed is too slow, or the cross chain length is too long. Remove one pitch from the
cross chain and check for rope pileup at the ends of the drum. Make further adjustments to the cross
chain length by removing additional links if necessary.
If the rope leaves an opening at both ends of the drum, the cross chain length is too short. Add one
pitch to the cross chain and check for openings at the ends of the drum. Add additional links if nec-
essary.
6. Lubrication
Every 3 months or seventy five (75) hours of operation, the level wind assembly should be lubricat-
ed in accordance with the instructions shown on figure 4.
Use standard motor oil in four oil cups marked “C”, three roller chains (lubricated on the inside sur-

face of the chain) coat the guide bars with a rust inhibitor such as LPS 3 Premier rust inhibitor or
equivalent. Reapply the rust inhibitor to prevent corrosion once every month.
To check for the proper oil level in the speed reducer, remove the oil level plug in the side of the
housing, lubricant should be maintained to the height of the oil level opening. Fill to the proper oil
level with 80W140 oil or equivalent
To add oil, remove the oil level plug in the side of the housing. Remove the oil filler plug at the top
of the housing. Add oil to the height of the oil level opening. Be sure to replace the plug at the top
and on the side of the housing.

Sprocket And Chain Selection
As previously specified, the number of teeth in the roller chain sprockets and the
length of chain is fixed depending on the specific rope diameter being used.
NOTE:
● The WG winch is designed to accept 7/16” diameter wire rope only.
● American produced wire rope is never smaller than the nominal diameter, always larger with
a plus tolerance of 1/32” in the size range used on GMP Adams Winches. Some foreign
product may be smaller.
● Should synchronization difficulty be experienced with standard sprockets, measure the diam-
eter of the wire rope in three locations with a micrometer and contact GMP.
● Sprockets and chains are 5/8” pitch, single width roller chain for the 1st and 2nd reduction.
● Sprockets and chains are 5/8” pitch, triple width roller chain for the cross chain.
● For the location of sprockets and chains see drawing on page 10.
To change the sprocket ratio to adjust for rope diameter tolerances,
1. Measure the wire rope in three different locations using a micrometer.
2. Contact GMP at 215-357-5500 and provide the wire rope diameter so the proper sprockets can
be determined.
3. Follow the following procedure after the sprockets are received.

4. Remove the chain guards from the sprocket(s) to be changed. Be careful to not lose the hard-
ware.
5. To loosen the chain loosen the jam nuts on the idler adjustment shaft.
6. Remove the chain connector and remove the chain from the sprocket(s) to be removed.
7. Loosen the set screw on the sprocket and remove the sprocket. Take note of the direction the
hub is mounted on the shaft. Be careful not to lose the key.
8. Place new sprocket on the shaft with the key in the keyway in the shaft.
9. Align the new sprocket(s) by placing a straight edge on the sprockets to align them with each
other.
10. Tighten the set screw on the new sprocket and the jam nuts on the idler sprocket adjustment
shaft.
11. Place the chain on the sprocket and add chain connector.
12. Adjust the idler sprocket to take up any slack in the chain. Check the tension in the chain by ro-
tating the drum by hand one complete revolution. Be careful not to over tighten the chain. There
should be at least 1/2 in. slack at it’s loosest position.
13. Replace the chain guards.
14. Set the timing of the level wind carriage by rotating the drum until the rope clamp is at the 12 to
1 o’clock position (6 to 7 o’clock for under-wind) when viewing the drum from the right side.
15. Position the carriage at a position of maximum travel at the drum end where the rope is to be
attached. The extreme end of the carriage travel is when the guide link is on the outside of the
end sprocket and at the mid-point of the vertical slot in the carriage.
16. Thread the end of the rope through the roller cage and attach it to the drum by means of the
rope clamp. See figure 2.
17. Drive the winch forward at a low speed, keeping sufficient tension on the rope. It is extremely
important that the first lay of rope be straight and compact. Slowly increase the drum speed and
spool on the remaining rope.
Whenever possible, a winch line holder should be used to prevent the rope from unwinding.
8. Wire Rope
8.1 Spooling
● When installing the wire rope observe the following recommendations: It is important to select
the correct winch rope for a particular application. Wire rope is specified by length, diameter,
number of strands, number of wires per strand, type of center and type of lay. The purpose is
to stress the importance of selecting the correct type of lay.
● There is a definite advantage in applying wire rope of the proper direction of lay when spooling
onto the smooth surface of the winch drum. A rope with an improper lay may cause the coils
will spread apart each time the load is removed. Installing the wire rope with the proper lay will
tend to keep the coils together when the load tension is removed. The correct lay will develop
tight coils and even layers.
● It is important to install the wire rope onto the winch drum with care. Kinking of the rope,
caused by the rope taking a spiral shape as a result of an unnatural twist, should be avoided.
● When removing wire rope from the reel and spooling onto the winch drum, the reel must be
supported on a horizontal axis and free to rotate. Spool the rope onto the drum with the natu-
ral bend in the same direction as it comes off the reel.
● If wire rope is received in a coil, it should be unwound with the coil in the vertical plane. Again,
spool the rope onto the winch drum with the natural bend in the same direction as it was on
the coil. Reverse bending of the wire rope should always be avoided or kept to a minimum.
IMPORTANT! Wire rope should always be under tension when spooling onto the winch drum.
● When the winch drum is in free spool and the drum shaft extension only is being used with a
capstan or reel, pass the winch line through the tail shelf sheave and hook the pulling eye to a
fixed section of the chassis. This will prevent the rope from unwinding or “clock-springing.”
● Likewise, when the winch is not in operation, attach the winch line quick hook to a solid mem-
ber on the tail shelf and slowly take up the slack. This will best maintain the rope under a

slight amount of tension until required again and will prevent the rope from unwinding or “clock
-springing.”
8.2 Winch drum rotation:
Note: The CD3 is available in an UNDER WIND and OVER WIND configuration
The WG winch is only available in an UNDER WIND configuration.
Over winding – is when the winch drum rotates in a clockwise direction (viewing from the right
side) and the wire rope is spooled onto the winch drum at the top. It is imperative that the wire
rope be attached to the correct side of the drum for the specific direction of the lay of the rope
given the direction of drum rotation. When the drum will be over winding as the wire rope is
spooled in, use the rope clamp on the side of the drum which is the same as the lay of the wire
rope. For example, if using right lay rope on an over wind drum attach the wire rope to the right
side rope clamp.
Under winding – is when the winch drum rotates in a counterclockwise direction (viewing from
the right side) and the wire rope is spooled onto the winch drum at the bottom. Once again, it is
imperative that the wire rope be attached to the correct side of the drum for the specific direction
of the lay of the rope given the direction of drum rotation. When the drum will be under winding
as the wire rope is spooled in, use the rope clamp on the side of the drum which is opposite of
the lay of the wire rope. For example, if using right lay rope on an under wind drum attach the
wire rope to the left side rope clamp.
The wire rope must be guided and maintained as it is routed forward under the body deck to the
winch drum. This can be done by using a trough or tube with sufficient width at the front and
depending on the angle of incline combined with the body cross-member configuration, a float-
ing sheave or roller may be required. Application engineering assistance is available from GMP.
WARNING! The cable clamp alone is not designed to hold the rated load. Approximately ½ of the
first layer of winch line must be left on the drum to achieve the rated load and avoid
cable clamp failure.
9 Lubrication:
● Wire rope is considered to be a machine, having many moving parts. Each time the rope
bends or flexes, the various wires and strands slide over each other. Lubrication is required
to facilitate this movement.
● The type of lubricant, method of applying and frequency of application is dependent on each
particular circumstance. For specific lubrication details contact the wire rope manufacturer.
