Section II. PREVENTIVE MAINTENANCE CHECKS AND SERVICES

CAUTION

Do not use solvent of any kind to

clean the oil filter housing. If solvent

gets into the lubricating system, it

can thin the oil so that it no longer

protects the engine from wear.

(4) Wipe the interior of the filter housing with a

clean, dry cloth.

(5) Install a new filter element in the filter

housing.

(6) Replace gasket and cap. Before you tighten

the attaching screw, carefully check the position of the

gasket. If the cap is slightly tilted, the gasket probably is

not seated. Loosen the screw and recheck it. When

you are sure that the gasket is in its correct position,

tighten the screw on the cover. It is not necessary to

tighten the screw with all your strength, but it must be

tight enough so that it will not loosen up during

operation.

(7) Add 51/2 quarts of the proper grade oil (see

para 3-3 a ) through the oil filler. Wipe off oil filter

housing and filler tube.

(8) Start engine and watch the oil filter closely.

If the gasket is not properly seated, a large amount of oil

can be lost in a very short time. No leakage is

permitted. If you see any leakage, stop the engine

immediately and repeat step (6) above to stop the leak.

(9) Shut off the engine after 3 to 5 minutes.

Wait 5 to 10 minutes for the engine oil to drain back into

the crankcase, and check the oil level on the dipstick (8,
