Winch General
Inspect all screws, bolts and nuts. Ensure they are securely attached and tight. Check to see
(Figure 2)
if any bolts, nuts or other parts are missing, or have been substituted or altered in any way.
Inspect covers, housings, guards, etc. Ensure they are free of cracks, dents, or other damage.
8101000 Series
Check operation of the winch in high and low speed positions; it must crank up and down
(Figure 2)
freely. Stiff or rough operation may indicate a worn gear or bearing.
Inspect the ratchet brake. With the brake engaged, the drum should be prevented from paying
off cable. The spring must be in place and undamaged. The ratchet brake lever must fully
engage the teeth on the drum, the drum teeth must be in good condition.
Inspect for oil in the gearbox by removing plug on top and tilting unit so oil can be seen
through hole. Inspect for oil leaks.
Check operation of the handle over speed brake as follows:
1. Over level ground set up support structure and winch as it will be used.
2. By raising or lowering the winch cable, position the lifting hook to approximately chest
height.
3. Remove the winch crank handle and have someone hold the ratchet brake lever in its
disengaged position, such as when lowering a load.
4. Pull down sharply on the lifting hook to engage the over speed brake.
5. If the brake fails to engage or noticeable brake slippage occurs, remove from service and
return to an authorized service center for repair.
(Figure 11)
Check operation of the drum over speed brake as follows:
1. To test the drum over speed brake, remove the handle over speed brake assembly. Using a
snap ring pliers, remove the ring (D) that retains the handle over speed brake assembly on
the low speed shaft. Remove the brake assembly (G), taking care not to damage the pawl
springs on the back side of the brake. Note: If damage exists on the shaft such as a nick or
corrosion, repair the damaged area using a file or emery cloth before removing the brake
assembly.
2. With the handle over speed brake removed, on level ground, set up the support structure
and winch as it will be used. To test the drum over speed brake, remove the crank handle
and disengage the ratchet brake, then pull down sharply on the winch cable to engage
brake.
3. If the brake fails to engage or slippage of more than one inch occurs (a small amount of
brake slippage is normal), remove the winch from service immediately and return to an
authorized service center for repair.
4. If the brake functions properly, reassemble the handle over speed brake (G). Ensure the
pawls are in place and the "A" side is showing on each pawl. Reinstall the retaining ring
onto the shaft. Test the handle over speed brake for proper operation using the method
given in "Check operation of the handle over speed brake" above.
Inspect the level wind (J) assuring that it moves freely and applies pressure against the line. If
the plastic wear pad (I) needs to be replaced, return the winch to an authorized service center.
8102000 Series
Check operation of the free-wheel mode and the drum over speed brake as follows:
(Figure 2)
1. Engage free-wheel mode by connecting the crank handle to the free-wheel shaft and
rotating the handle counterclockwise. The winch line should pay out freely. Pull down
sharply on the winch line with the winch in the free-wheel mode to engage the brake.
2. The brake must lock and hold. If the brake fails to engage or slippage of more than one
inch occurs (a small amount of brake slippage is normal), remove the winch from service
immediately and return to an authorized service center for repair.
(Figure 13)
Inspect the shear pin (B). The shear pin should retain one complete wrap (A) of line on the
drum. If the shear pin is broken or missing the unit must be returned to an authorized service
center for repair.
(Figure 12)
Inspect the impact indicator (C) on the snap hook. If the hook is in the indicated mode, return
the winch to an authorized service center for repair.
(Figure 14)
Inspect the level wind (A) assuring that it moves freely and applies pressure against the line. If
the plastic wear pad (B) needs to be replaced return the winch to an authorized service center.
Crank Handle Screws
Removable Crank Arm (K) must lock positively into each of the drive hubs and be free of
(Figure 2)
cracks, bends, or other damage. Check that each handle on the crank arm is tight. Use Loctite
262 or equivalent thread lock on the anchor screws if required to keep them tight. Do not use
unless the crank arm is fully functional.
Connecting Hook
Connecting hook (A) must not be damaged, broken, distorted, or have any sharp edges, burrs,
(Figure 2)
cracks, worn parts, or corrosion. Ensure the connecting hook works properly.
Hook gate must move freely and lock upon closing. Hook must swivel freely.
Wire Rope:
Inspect entire length of wire rope assembly starting at the hook. Always wear protective gloves
when inspecting wire rope. Inspect for broken wires by passing the wire rope through gloved
hands, flexing it every few inches to expose breaks. Inspect for kinks, cuts, crushed burned
areas, corrosion, or other damage. Wire rope with serious damage must be removed from
service.
Synthetic Rope:
Inspect for concentrated wear, frayed strands, broken yarns, cuts, and abrasions. The line
must be free of knots, excessive soiling, heavy paint buildup, and rust staining throughout its
length. The line must be free of ultraviolet damage, indicated by discoloration and the presence
of splinters and slivers on the rope surface. All of the above factors are known to reduce rope
strength. Damaged or questionable rope must be replaced by an authorized service center.
