Remove the oil pump cover(A) from the timing chain cover.
Drain the engine oil.
Remove the drive belts.
Turn the crankshaft pulley, and align its groove with timing mark "T" of the timing chain cover.
Remove the Oil pan
Remove the timing chain cover.
Remove the oil pump cover(A) from the timing chain cover.
Remove the inner rotor and outer rotor.
Remove the relief plunger.
Remove the plug(A), spring(B) and relief plunger(C).
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 it does not, replace the relief plunger. If necessary, replace the front case.
Inspect the rotor side clearance.
Using a feeler gauge and precision straight edge, measure the clearance between the rotors and precision straight edge.
Side clearance | Outer rotor | 0.04 ~ 0.09mm (0.0016 ~ 0.0035in) |
Inner rotor | 0.04 ~ 0.085mm (0.0016 ~ 0.0033in) |
If the side clearance is greater than maximum, replace the rotors as a set. If necessary, replace the front case.
Install the relief plunger.
Install relief plunger(C) and spring(B) into the front case hole, and install the plug(A).
Tightening torque :
25.5 ~ 34.3N.m (2.6 ~ 3.5kgf.m, 18.8 ~ 25.3lb-ft)
Install the oil pump.
Place the inner and outer rotors into front case with the marks facing the oil pump cover side.
Install the oil pump cover(A) to timing chain cover with the screws.
Tightening torque :
5.9 ~ 8.8N.m (0.6 ~ 0.9kgf.m, 4.3 ~ 6.5lb-ft)
Check that the oil pump turns freely.
Install the timing chain cover.
