6. Engine Oil Pressure

G2M0093
4) Connect oil pressure gauge hose to cylinder block.
5) Start the engine, and measure oil pressure.
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
CAUTION:

If oil pressure is out of specification, check oil
pump, oil filter and lubrication line.


If oil pressure warning light is turned ON and oil
pressure is in specification, replace oil pressure
switch.

NOTE:
The specified data is based on an engine oil temperature
of 80°C (176°F).
6) After measuring oil pressure, install oil pressure switch.
Tightening torque:
25±3 N⋅m (2.5±0.3 kg-m, 18.1±2.2 ft-lb)
7) Install generator and V-belt in the reverse order of
removal, and adjust the V-belt deflection.

1. General Precautions
1) Before disassembling engine, place it on ST3.
ST1 498457000 ENGINE STAND ADAPTER RH
ST2 498457100 ENGINE STAND ADAPTER LH
ST3 499817000 ENGINE STAND
2) All parts should be thoroughly cleaned, paying special
attention to the engine oil passages, pistons and bearings.
3) Rotating parts and sliding parts such as piston, bearing
and gear should be coated with oil prior to assembly.
4) Be careful not to let oil, grease or coolant contact the
timing belt, clutch disc and flywheel.
5) All removed parts, if to be reused, should be reinstalled
in the original positions and directions.
6) Gaskets and lock washers must be replaced with new
ones. Liquid gasket should be used where specified to
prevent leakage.
7) Bolts, nuts and washers should be replaced with new
ones as required.
8) Even if necessary inspections have been made in
advance, proceed with assembly work while making
rechecks.
2. Hydraulic Lash Adjuster
A: INSPECTION
1) Disconnect blow-by hose from rocker cover.
2) Remove spark plug cap.
