Clearance 6 = (regulator valve hole diameter D) - (outer regulator valve diameter E).
If the calculated clearance 6 exceeds the standard, replace the oil pump body.
- Clearance 6: 0.040 - 0.097 mm (0.0016 - 0.0038 in)
CAUTION:
- Coat the regulator valve with clean engine oil.
- Check that it falls smoothly into the valve hole by its own weight.
