Oil Specifications
Engine
Heavy-duty engine oil SAE 15W-40 meeting API
Classification CG-4.
Automatic Transmission
The transmission must be filled with
Dexron IIE
or
Dexron III
automatic transmission fluid or any
equivalent Class C4 fluids.
Differential
Multigrade gear oil meeting MIL-L-2105-D:
85W140 is recommended for use in drive axle.
This lubricant performs well over broad tem-
perature range, providing good gear and bearing
protection in a variety of climates.
If temperature drops below 10°F (-12°C), 80W90
should be used, and below -15°F (-26°C),
75W90 should be used. In extreme conditions or
for better performance, full synthetic gear oil can
be used.
Fan Gearbox
Synthetic oil
Mobil SHC 630 (Prévost #180217)
is recommended for the fan gearbox.
Power Steering Reservoir
This reservoir must be filled automatic transmis-
sion oil,
Dexron IIE
or
Dexron III
.
Wheel Bearings
The front and tag axle wheel bearings must be
filled to the level mark in the cap using differen-
tial oil. Drive axle wheel bearings are lubricated
by the differential oil. Maintain differential oil level
to ensure adequate lubrication of drive axle
wheel bearings at all times.
On vehicles equipped with grease-lubricated
wheel bearings, pack with wheel bearing grease.
