8. Recommended Planetary Gear Oil
Field experience, supported by engineering endurance tests, indicates that the use of the proper gear oil and a program
of regular preventive maintenance will help provide extended gear-train life and reliable winch brake performance. For
this reason, PACCAR Winch has published the following specifications to assist in determining which lubricant is best
suited to your application.
For simplicity, PACCAR Winch has listed available products in each temperature range that have been tested and
found to meet our specifications. This is not to say that other lubricant brands would not perform equally as well.
If the following lubricant brands are not available in your area, make certain your lubricant vendor supplies you with oil
equivalent to those products listed below.

PREVENTIVE MAINTENANCE
Failure to use the proper type and viscosity of planetary gear oil may contribute to intermittent brake clutch slippage,
which could result in property damage, severe personal injury, or death. Some gear lubricants contain large amounts
of extreme-pressure (EP) and antifriction additives, which may contribute to brake clutch slippage or damage to brake
friction discs or seals.
NOTE: DO NOT use oil that is labeled as meeting “API Service GL-5.”
Oil viscosity, af-
fected by ambient temperature, is also critical to reliable brake clutch operation. Our tests indicate excessively heavy
or thick gear oil may contribute to intermittent brake clutch slippage. Make certain the gear oil viscosity used in your
winch is correct for your prevailing ambient temperature.
