OIL SPECIFICATIONS
ENGINE
Heavy-duty engine oil SAE 15W-40 meeting API
classification CG-4 and military specification
MIL-L-2104E.
ALLISON TRANSMISSION
The Allison transmission must be filled with
Dexron IIE, Dexron III or automatic transmission
fluid or any equivalent Class C4 hydraulic fluid.
EATON TRANSMISSION
 Semi-automatic transmission:
Use CD50 synthetic fluid.
 Automatic transmission:
Use Dexron III fluid.
SPICER TRANSMISSION (ALL)
Use heavy-duty engine oil SAE 30 (for northern
climate), SAE 40 or SAE 50 meeting API
classification CG-4 and military specification
MIL-L-2104E.
DIFFERENTIAL
Multigrade gear oil meeting MIL-L-2105-D:
85W140 is recommended for use in drive axle.
This lubricant performs well over a broad
temperature 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
should be used.
FAN GEARBOX
Only Mobil SHC 630 synthetic oil (Prevost
#180217) is recommended for the fan gearbox.
POWER STEERING RESERVOIR
Use Dexron IIE or Dexron III automatic
transmission fluid for this system.
CLUTCH MASTER CYLINDER
If equipped with a semi-automatic or a manual
transmission, use DOT 3 heavy-duty brake fluid
for this system.
WHEEL BEARINGS
If oil is to be added, use general purpose gear
lubricant SAE 85W/140 (API spec. GL5).
Refer to Care and Maintenance chapter for
details on adding oil.
PRE-HEATING SYSTEM
Depending on options chosen, a coolant heater
may be installed on the coolant circuit. The
heater can be used as a pre-heater or as an
auxiliary heat source.
Choices are either the Webasto 80,000 Btu, the
Webasto 45,000 Btu or the Espar 41,000 Btu
heaters. The Heater is controlled by a
programmable timer. See Other Features
chapter for information on using the timer.
