IMPORTANT
■ Gearbox is not filled at the factory. Prior to
delivery, make sure each gearbox is filled half-full
with 80W or 90W API GL-4 or GL-5 gear lube.
1. Make sure vent plug hole is clear. Fill gearbox half-
full with high quality gear oil that has a viscosity
index of 80W or 90W and an API service rating of
GL-4 or GL-5.
2. Fill gearbox until oil runs out the side plug on
gearbox.
3. Pour in one pint of gear lube, wait five minutes and
add additional gear lube until it just comes out of
side hole.
4. Allow an additional five minutes for the lube to flow
through bearings, then check to make sure oil level
is at bottom of side hole. Replace side plug. Install
vent plug.
