Oil Pump


NOTE: Whenever internal engine components wear
excessively or break and whenever oil is contami-
nated, the oil pump should be replaced.

2. Using a suitable "T" fitting, connect Oil Pressure
Test Kit to the oil fitting and hose. Tighten all clamps
securely.

Allow the engine to warm up to operating tempera-
ture (with cooling fans cycling). Press and hold the
brake pedal; then shift into neutral.

oil hose. Tighten the clamps securely.

NOTE: If oil pressure is lower than specified, check
for an oil leak, clogged oil filter, or defective oil pump.


for too heavy engine oil weight (see General Informa-
tion/Foreword), clogged oil passage, or improper
installation or type of the oil filter.
