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.
<Ref. to 2-4 [K100].>
If oil pressure warning light is turned ON and oil
pressure is in specification, replace oil pressure
switch.
<Ref. to 2-4 [W3A0].>
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.

shows unsatisfactory results.
Immerse the thermostat and a thermometer in water. Raise
water temperature gradually, and measure the temperature
and valve lift when the valve begins to open and when the
valve is fully opened. During the test, agitate the water for
even temperature distribution. The measurement should
be to the specification.
Starts to open:
76.0—80.0°C (169—176°F)
