PREVENTATIVE MAINTENANCE
A regular program of preventive maintenance for your PAC-
CAR 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.
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 level must be checked. If no leaks are de-
tected, the oil level may be checked once every 250 hours
or monthly. The oil level plug is located below the left hand
gear cover toward the rear of the winch. Position the trac-
tor on a fl at, level surface and remove the plug. The oil
should be at the bottom of the level plug hole.
Add oil as required through the oil fi ller plug located above
the lower bearing carrier.
Refer to the recommended oil chart for the proper oil for
your application.
GREASE
There is one grease fi tting on each side of the winch case
to which grease should be added every 50 hours. Use
a NLGI #2 EP (extreme pressure) grease with a Lithium
complex base that meets or exceeds NLGI GC or GC/
LB requirements. Pump grease into the upper right drum
bearing grease fi tting until grease comes out the small vent
hole in the cover. Pump about ½ ounce into the grease
fi tting for the second reduction shaft on the left side of the
winch. This will be about 10 strokes with a standard vol-
ume (1.0 to 1.5 grams/stroke) lever operated grease gun.
TRACTOR HYDRAULIC RESERVOIR LEVEL
The tractor hydraulic oil reservoir level should be checked
at the sight glass daily, or in accordance with the tractor
manufacturer’s recommendations. Use the type of hydrau-
lic oil recommended by the tractor manufacturer.
Change the tractor hydraulic oil in accordance with the
tractor manufacturer’s recommendations.
GEAR CASE OIL CHANGE
Change the winch gear case oil after the fi rst 100-250
hours of operation, then every 1000 hours or six (6)
months, whichever occurs fi rst.
Hot oil can cause injury. Make certain the oil has cooled
to a safe temperature (less than 110°F or 43°C) before
servicing the winch.
NOTE:
Grease displaced from the second reduction gear
shaft bearings during greasing may drain from the winch
with the oil.
Remove the drain plug located at the bottom left side of
the winch housing. Drain the oil into a suitable container
and recycle or dispose of the used oil in an environmen-
tally responsible manner. Contact your local government
agency for information concerning proper disposal. Install
the plug securely after the oil has been drained. To reduce
oil drain time, remove the fi ller/vent plug.
Refi ll the winch to the proper level with the recommended
oil.
Oil capacity:
approximately 5 qt. (4.7 L)
DO NOT
operate the winch while the oil is drained. Se-
rious damage to internal components may result.
CAUTION
HYDRAULIC OIL FILTER
If a hydraulic oil fi lter was installed when the winch was
installed on the tractor, replace it on the same interval as
the other tractor hydraulic oil fi lters.
VENT PLUG
The vent plug is installed in the left hand gear cover.
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 gear oil during operation will
cause a build-up of pressure in the gear case, which may
lead to seal leakage.
