Inspection
1. Inspect relief plunger.
Coat the valve with engine oil and check that it falls smoothly into the plunger hole by its own weight.
If it does not, replace the relief plunger. If necessary, replace the front case.
2. Inspect relief valve spring.
Inspect for distorted or broken relief valve spring.
Standard value
Free height : 43.8mm (91.724in.)
Load : 4.6kg/39.1mm (10lb/1.547in.)
3. Inspect rotor side clearance.
Using a feeler gauge and precision straight edge, measure the clearance between the rotors and precision straight edge.
Side clearance
0.04 - 0.095mm (0.0016 - 0.0037in.)
If the side clearance is greater than maximum, replace the rotors as a set. If necessary, replace the front case.
4. If the tip clearance is greater than maximum, replace the rotor as a set.
5. Inspect rotor body clearance.
Using a feeler gauge, measure the clearance between the outer rotor and body.
Body clearance
0.100 - 0.181mm (0.0039 - 0.0017in.)
If the body clearance is greater than maximum, replace the rotors as a set. If necessary, replace the front case.
