ENGINE
For further engine information, see Engine Shop Rebuild
and Service Parts Manual.
POWERTRAIN MAINTENANCE
Access the powertrain by raising or removing seat. Some
service procedures may require the vehicle be lifted.
Refer to LIFTING THE VEHICLE in the SAFETY section
for proper lifting procedure and safety information.
Checking the Oil Level
Do not overfill engine. Too much oil
may cause smoking or allow oil to
enter the air filter enclosure.
NOTICE: Vehicles with the leaf springs mounted on
top of the rear axle will have an oil dipstick with an
’H’ stamped into the top.
The oil should be checked with the engine warm. The
vehicle should be on a level surface with the parking
(PARK) brake engaged. Allow adequate time for oil to
drain into the crankcase before checking.
Remove the oil dipstick and wipe off the entire area with
a lint free cloth (Ref. Fig. 1).
Fig. 1 Oil Dipstick
Insert the dipstick
fully
into the dipstick opening and
remove. Examine the level of the oil on the dipstick.
Fig. 2 Check Oil Level on Dipstick
The engine can be operated safely as long as oil is within
the safe operating range as indicated on the dip stick.
Do
not operate vehicle if oil level is below the safe area
indicated on the dipstick.
Oil should be added to bring the level into the safe oper-
ating range. Remember that oil expands as it gets hot,
Do not overfill
(Ref. Fig. 2). Check that the oil cap is
firmly in place.
NOTICE: When adding oil between oil changes, do
not mix brands and viscosity grades of oil.Both the
oil dipstick and fill cap must be in place before
operating the engine. Failure to install the dipstick
and fill cap will result in oil becoming contaminated
and/or oil being discharged into the engine com-
partment.

For maximum performance and longevity, the engine oil
should be replaced after the first 8 hours of operation.
After the initial oil change, it should be changed every
125 hours of operation or semi-annually, whichever
comes first.
The selection of oil is dependent upon the service that
the vehicle will perform. Most vehicles require 10W-30
oil, whereas vehicles used at capacity or near capacity
load applications will utilize 10W-40 oil after a break-in
period of 8 hours
