CAUTION
Replace oil-coalescing desiccant air
dryer
cartridge every 1 year regardless
of mileage. Only use oil-coalescing
desiccant replacement cartridge when
replacing. Failure to perform this main-
tenance task will void the PACCAR
Transmission warranty and may result
in expensive transmission damage.
Fuller Transmission Lubrication
Fuller transmissions are designed so that
the internal parts operate in a bath of oil
circulated by the motion of gears and
shafts. Grey iron parts have built-in
channels where needed to help lubricate
bearings and shafts. All parts will be amply
lubricated if these procedures are closely
followed:
1. Maintain oil level; check it regularly.
2. Change oil regularly.
3. Use the correct grade and type of
oil.
4. Buy oil from a reputable dealer.
