For best performance and maximum protection of all types of operation, select only those lubricants which :a. Satisfy the requirement of the API classification.
b. Have proper SAE grade number for expected ambient temperature range.
Lubricants that do not have both an SAE grade number and API service classification on the container should
not be used.
RELIEF SPRING
1.Check the relief plunger.
Apply engine oil on the plunger and check that it moves smoothly in the hole. If it does not, replace the plunger or
the front case only in necessary cases.
2. Check the relief valve spring.
Check deformation or damage of the relief valve spring.

OIL PRESSURE SWITCH
1.Check the continuity between the terminal and the body with an ohmmeter.
If there is no continuity, replace the oil pressure switch.
