PREVENTIVE MAINTENANCE
WARM-UP PROCEDURE
The tractor engine should be run in accordance with the
tractor manufacturer’s recommendations to warm up the
hydraulic system. Use cold-weather oil as recommended
in the tractor hydraulic system instructions.
FAIRLEAD ROLLERS
Grease the fairlead rollers at the beginning of each work-
day. Roller shafts have grease fittings at both ends. Apply
grease until a small amount pushes out around the shaft.
Use a high-quality 12-hydroxy stearate lithium-based
product, which contains an EP additive, such as Moly, and
meets or exceeds an NLGI Grade 2 specification.
INSPECTION
Disassemble winch every 10,000 hours or four years,
whichever occurs first, for a thorough inspection of all
wear items. Refer to the disassembly and assembly sec-
tions of this manual for additional information.

RECOMMENDED OIL
The following specifications will help determine which
lubricant is best suited to your application. The oil must
possess high-temperature oxidation stability, rust and cor-
rosion protection, good dispersant and detergent charac-
teristics, antiwear additives, and remain compatible with
nitrile-based seals.
Your lubricant supplier should assure you that his product
meets this specification. If there is any doubt of the suit
-
ability of a lubricant, contact the PACCAR Winch Service
Department, providing a copy of the product specifications.
