PREVENTIVE MAINTENANCE
A regular program of preventive maintenance for your
Paccar winch will minimize the need for emergency
servicing and promote long product life and trouble-free
service.
The service intervals suggested in this manual will opti-
mize component service life. The intervals may be grad-
ually increased or decreased with experience of a par-
ticular lubricant and evaluation of your application.
Gear Case Oil Level
The winch assembly should be visually inspected for
leaks at the beginning of each workday. If oil leaks are
found, the gear case oil must be checked. If no leaks are
detected, the oil level may be checked once every 250
hours or monthly. Position the tractor on a flat, level sur-
face and remove the plug. The oil should be at the bot-
tom of the level plug hole.
Add oil as required through the oil fill plug. Add oil slow-
ly, as the oil must pass through the gear train and fill the
cable drum cavity.
Refer to the recommended oil chart for the proper oil for
your application.
Tractor Hydraulic Reservoir Level
The tractor hydraulic reservoir oil level should be
checked daily or in accordance with the tractor manu-
facturer’s recommendations. Use the type of hydraulic
oil recommended by the tractor manufacturer.
Change the tractor hydraulic oil and filter every 1000
hours or in accordance with the tractor manufacturer’s
recommendation.
Gear Case Oil Change
Change the winch gear case oil after the first 100-250
hours of operation, then every 1000 hours or six months,
whichever occurs first.
Remove the oil drain plug. Drain oil into a suitable con-
tainer and recycle or dispose of used oil in an environ-
mentally responsible manner. Install the plug securely
after the oil has been drained.
Refill winch to proper level with recommended oil. Allow
15 minutes for the oil to flow through the gear train and
fill the cable drum cavity before checking oil level.
Oil Capacity: Approximately 25 pint (12L)
Vent Plug
The vent plug is installed in the oil filler plug located near
the top of the drum clutch housing. Whenever the oil is
changed, remove the vent plug, clean in safety solvent
and reinstall.
Note: Do not replace the vent plug with a solid plug. The
normal expansion of the oil during operation would
cause a build-up of pressure in the gear case which may
lead to seal leakage.
Winch Cable (Wire Rope)
Inspect entire length of wire rope and hook in accor-
dance with the rigging manufacturer’s recommenda-
tions.
Mounting Fasteners
Check/tighten all winch mounting fasteners to recom-
mended torque after the first 100-250 hours of operation,
then every 1000 operating hours or six (6) months,
whichever occurs first.
Warm-up Procedure
The tractor should be run at its lowest RPM with the
winch control in the neutral, brake-on position allowing
sufficient time to warm the hydraulic system or in accor-
dance with the tractor manufacturer’s recommendations.
The winch should then be operated under a no-load con-
dition, in haul-in and pay-out direction several times to
prime the lines with warm hydraulic oil and circulate gear
lubricant through the brake and gear train. This action
will minimize the temporary increase in “brake-off” drag
caused by cold oil.
Hot oil may cause injury. Make certain oil has cooled
to a safe temperature before servicing.
CAUTION
WARNING
!
!
Do not operate winch while oil is drained. Serious
damage to internal components may result.
