2.2 Inspecting relief valve
(1)
Check the relief valve and its seat for contact. Check
the spring for fatigue and damage. If faulty, replace the
relief valve with new one.
(2) Measure the relief valve opening pressure. If the
pressure does not fall within the standard range, replace
the relief valve with new one.
Note: Start oil pressure measurement at the engine front
side (gear case).

2.3 Inspecting oil pressure switch
(1)
Connect a tester (ohm range) between the terminal and
body to check for continuity. The switch is normal if
there is continuity between them. If there is no
continuity, replace the switch.
(2) Insert a thin rod from the oil hole and lightly push it.
The switch is normal if there is no continuity between
them. If there is continuity when the rod is pushed in,
replace the switch.
(3) When air pressure of 0.05 MPa {0.5 kgf/cm²} [7.1 psi]
is applied from the oil hole and there is no continuity,
the switch is normal. Also check for air leaks. If there
are air leaks, the diaphragm is damaged. Replace the
switch.
