1. | Remove the cam chain. |
2. | Remove the oil screen (A), then remove the oil pump (B).
|
1. | Remove the pump cover. |
2. | Check the inner-to-outer rotor radial clearance between the inner rotor (A) and outer rotor (B). If the inner-to-outer rotor radial clearance exceeds the service limit, replace the oil pump.
|
3. | Check the housing-to-rotor axial clearance between the rotor (A) and pump housing (B). If the housing-to-rotor axial clearance exceeds the service limit, replace the oil pump.
|
4. | Check the housing-to-outer rotor radial clearance between the outer rotor (A) and pump housing (B). If the housing-to-outer rotor radial clearance exceeds the service limit, replace the oil pump.
|
5. | Inspect both rotors and the pump housing for scoring or other damage. Replace parts if necessary. |
6. | Install the oil pump cover. |
1. | Install the dowel pins (A) and new O-ring (B) on the oil pump (C), then align the inner rotor with crankshaft, and install the oil pump.
