Maintenance
Checking/Filling Engine Oil Level
IMPORTANT: Care must be taken when checking
engine oil level. Oil level must be maintained between
the "ADD" mark and the "FULL" mark on the dipstick.
To ensure that you are not getting a false reading,
make sure the following steps are taken before
checking the oil level.
Figure 2-2 Engine Oil Dipstick (Typical)
1. Stop engine if in use.
2. Allow sufficient time (approximately 5 minutes) for
the oil to drain back into the oil pan.
3. Remove dipstick. Wipe clean and reinstall.
Push dipstick all the way into the dipstick tube.
4. Remove dipstick and note the oil level.
5. Oil level must be between the "FULL" and "ADD"
marks (figure 2-2).
6. If the oil level is below the "ADD" mark, proceed to
Steps 7 and 8, and reinstall dipstick into the dipstick
tube.
7. Remove oil filler cap from the valve rocker arm
cover.
8. Add required amount of oil to bring level up to, but
not over, the "FULL" mark on dipstick.
CAUTION
Overfilled crankcases (oil level being too high) can
cause a fluctuation or drop in oil pressure and rocker
arm "clatter" on engines. The overfill condition results
in the engine crankshaft splash-ing and agitating the
oil, causing it to foam (become aerated). The aerated
oil causes the hydraulic valve lifters to "bleed down."
This, in turn, results in rocker arm "clatter"and loss of
engine performance due to the valves not opening
properly.
Changing Engine Oil And Filter
IMPORTANT : When changing the oil, always change
the oil filter.
1. Start engine and run until it reaches normal
operating temperatures.
IMPORTANT: Change oil when engine is warm from
operation as It flows more freely, carrying away more
impurities.
2. Stop engine.
3. Remove drain plug and allow all the oil to drain.
4. Remove and discard oil filter and its sealing ring.
5. Coat sealing ring on new filter with clean engine oil,
and install new filter. Tighten filter securely
(following filter manufacturer's instructions). Do not
overtighten.
6. Fill crankcase with oil.
7. Start engine and check for oil leaks.
Accessory Drive Belts
Engine must be shut off and the lgnltion key removed
before inspecting drive belts.
Check belt tension by pressing down on the midway
point of the longest stretch between two pulleys. The
belt should depress 1/2 in. (13mm). If depression is
more than allowable, adjust tension.
Inspect electrical system
• Clean battery outer surfaces with a mixture of baking
soda and water.
• Inspect battery outer surfaces for damage. Replace
as required.
• Remove battery cables and clean.
• Inspect battery cables for worn or missing
insulation, frayed wire and/or corrosion. Replace as
required.
