VEHICLE MAINTENANCE
4. A lightly soiled filter can be cleaned by tapping out dust. Do not use compressed air on the filter. If the filter is
heavily soiled, it must be replaced.
5. Reinstall or replace the filter, making sure it is fully seated in the housing.
6. Replace the housing and secure with latches.
LUBRICATION
Do not use more than three pumps of
grease in a grease fitting at any one time.
Excess grease can cause grease seals to
fail, or allow grease into areas that could damage compo-
nents.
Putting more than three pumps of grease in a grease fitting
could damage grease seals and cause premature bearing fail-
ure.
Lubricate components at the intervals indicated in the SCHED-
ULED MAINTENANCE CHART on page 46.
SPARK PLUG

aluminum cylinder head threads.
1. Remove the spark plug when the engine is cold.
2. Inspect and replace the spark plug at the intervals indicated in the SCHEDULED MAINTENANCE CHART on
page 46.
3. Apply a light coat of anti-seize compound to the spark plug threads.
