Oil filter element removal
Use a filter wrench to remove the cartridge type oil filter.
Oil filter element installation
1. Apply light coat of engine oil to the O-ring.
2. Turn in new cartridge until its sealed face comes in con-
tact with the O-ring.
3. Use a filter wrench to tighten the cartridge another 3/4 of
a turn.
Engine oil refilling
1. Reinstall the drain plugs. Remove the oil dipstick from
the engine to allow air to escape.
2. MODELS E673L, S773L, N844L, N844L-T ONLY
Add engine oil slowly. Pouring the oil too quickly can
result in the oil overflowing into the air breather valve
and then into the air intake manifold. Cranking the
engine with oil in the manifold will severely damage the
engine.
NOTE: If oil has entered the air intake manifold it will be
necessary to clean the oil from the cylinders. To clean the
cylinders, remove the fuel injection nozzles and turning
the engine with the starter until all oil is exhausted.
