| Removal and installation |
| 1. | Remove the timing chain cover. (Refer to Timing System - "Timing Chain Cover") |
| 2. | Remove the oil pump cover (A).
|
| 3. | Remove the inner rotor (A) and outer rotor (B).
|
| 4. | Install in the reverse order of removal. |
| Inspection |
| 1. | Remove the relief plunger. Remove the plug (A), spring (B) and relief plunger (C).
|
| 2. | Inspect the relief plunger. Coat the plunger with engine oil and check that it falls smoothly into the plunger hole by its own weight. If necessary, replace timing chain cover. |
| 3. | Inspect the relief valve spring. Inspect for distortion or breakdown of the relief valve spring. |
| 4. | Inspect the rotor side clearance. Using a feeler gauge and precision straight edge, measure the clearance between the inner rotors and precision straight edge. If the side clearance is greater than maximum, replace the rotors as a set. If necessary, replace the timing chain cover.
|
| 5. | Inspect the rotor body clearance. Using a feeler gauge, measure the clearance between the outer rotor and body. If the body clearance is greater than maximum, replace the rotors as a set. If necessary, replace the timing chain cover.
|
| 6. | Inspect the rotor guide clearance.
