B: INSTALLATION
1) Wipe and clean the oil filter matching surface on
cylinder block and oil cooler.
2) Get a new oil filter and apply a thin coat of engine
oil to the seal rubber.
CAUTION:
Be careful not to use the oil filter 80 mm (3.15 in)
in diameter to turbo model.
3) Install the oil filter by turning it by hand, being
careful not to damage seal rubber.
 Tighten the oil filter 80 mm (3.15 in) or 65 mm
(2.56 in) in diameter by approx. 2/3 — 3/4 rotation
more after the seal rubber of oil filter comes in con-
tact with cylinder block or oil cooler.
 Tighten the oil filter 68 mm (2.68 in) in diameter
by approx. 1 rotation more after the seal rubber of
oil filter comes in contact with cylinder block or oil
cooler.
CAUTION:
Do not tighten excessively, or oil may leak.
C: INSPECTION
1) After installing the oil filter, run the engine and
make sure that no oil is leaking around seal rubber.
NOTE:
The filter element and filter case are permanently
jointed; therefore, interior cleaning is not neces-
sary.
2) Check the engine oil level. 10, INSPECTION, Engine Oil.>

Engine Oil Pressure
6. Engine Oil Pressure
A: INSPECTION
1) Remove the oil pressure switch from engine cyl-
inder block. Pressure Switch.>
2) Connect the oil pressure gauge hose to cylinder
block.
3) Connect the battery ground cable to battery.
4) Start the engine, and then measure the oil pres-
sure.
Oil pressure:
98 kPa (1.0 kg/cm
2, 14 psi) or more at 800 rpm
294 kPa (3.0 kg/cm2, 43 psi) or more at 5,000
rpm
 If the oil pressure is out of specification, check oil
pump, oil filter and lubrication line. LU(H4SO)-24, INSPECTION, Engine Lubrication
System Trouble in General.>
 If the oil pressure warning light is turned ON and
oil pressure is in specification, replace the oil pres-
sure switch. Engine Lubrication System Trouble in General.>
NOTE:
The specified data is based on an engine oil tem-
perature of 80°C (176°F).
5) After measuring the oil pressure, install the oil
pressure switch. LATION, Oil Pressure Switch.>
