Repair and Service Manual
ENGINE
Read all of Section B and this section before attempting any procedure. Pay particular attention to all Notes, Cautions and Warnings.
For further engine information, see Four Cycle Engine
Shop Rebuild and Service Parts Manual, P/N 27615-
G01.
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 section ‘B’ 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.
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 dipstick and wipe off the entire area indi-
cated with a lint free cloth (Ref. Fig. 1 on Page G-1).
Fig. 1 Clean Entire Dipstick
Insert the dipstick
fully
into the dipstick hole 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 on Page G-1). Check that
the oil cap is firmly in place.
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 oper-
ating the engine. Failure to install the dipstick and fill cap will
result in oil becoming contaminated and/or oil being dis-
charged into the engine compartment.

Tool List

For maximum performance and longevity, the engine oil
should be replaced after the first 100 hours of opera-
tion. After the initial oil change, it should be changed
every 125 hours of operation or semi-annually, which-
ever 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 100 hours
(Ref. Fig. 3 on Page G-1).

If vehicle is to be stored over winter months, it can be stored
with old oil left in engine. The oil should be changed as part of
spring maintenance. This will remove any moisture that has
accumulated during storage.
