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,
