Gas/Vent Hoses

Replace the gas hose every two years. Damage from aging
may not always be visible. Do not bend or obstruct the
routing of the vent hoses. Make certain the vent hoses are
securely connected and the opposite ends are always open.

Oil Filter/Oil Pump

 NOTE: Whenever internal engine components wear
excessively or break and whenever oil is contami-
nated, the oil pump should be replaced.
TESTING OIL PUMP PRESSURE
 NOTE: The engine must be warmed up to operating
temperature (cooling fan cycling) for this test.
1. Remove the oil hose from the fitting nearest the oil filter
base.
2. Using a suitable "T" fitting, connect Oil Pressure Test Kit
to the lower oil fitting and hose. Tighten all clamps
securely.
 NOTE: Some oil seepage may occur when installing the
oil pressure gauge. Wipe up oil residue with a cloth.
3. Place the transmission in neutral and start the engine.
Set the speedometer/tachometer to RPM.
4. With the engine running at 3000 RPM and the coolant
at room temperature (approximately 70° F), the pres-
sure gauge must show 6.68-8.44 kg/cm
5. With the engine running at 3000 RPM and the coolant at
approximately 195° F (cooling fan cycling), the pressure
gauge must show 5.27-6.68 kg/cm
6. Remove the test kit from the vehicle and install the 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.
 NOTE: If oil pressure is higher than specified, check
for too heavy engine oil weight (see General Informa-
tion), clogged oil passage, or improper installation or
type of the oil filter.
