- Inspect the following areas of the oil pump:
| • | The oil pump housing and cover for cracks, scoring, casting imperfections
and damaged threads |
| • | The drive gear shaft (If the shaft is loose in the oil pump housing,
replace the oil pump.) |
| • | The pressure relief valve for scoring and sticking (Burrs may
be removed with a fine oil stone.) |
| • | The oil pump screen for broken wire mesh or looseness |
| • | The gears for chipping, galling and wear. |
- If the oil pump is to be reused, replace the pressure relief valve
spring.
Important: The oil pump is serviced as an assembly. Do not attempt to service the
individual components.
The pressure relief valve spring is the only serviceable component.
- Replace the pump if any wear to the pump gears or housing exists.
