- Check the clearance between the rotors in the
position shown in the diagram using a feeler
gauge.
Measure the distance between the outer rotor and
the pump body (see figure).
- Check the axial clearance of the rotors using a
trued bar as shown in the figure.
Characteristic
Axial rotor clearance
Limit values admitted: 0.09 mm
Distance between the outer rotor and the pump
body
Admissible limit clearance: 0.20 mm
Distance between the rotors
Admissible limit clearance: 0.12 mm
Refitting
- Check there are no signs of wear on the oil pump
shaft or body.
- Check there are no signs of scoring or wear on
the oil pump cover.
- If you detect non-conforming measurements or
scoring, replace the faulty parts or the unit.
- Fit the pump cover in the position that permits the
crankcase clamping screws to be aligned.
- Make sure the gasket is positioned properly and
refit the pump on the engine crankcase. The pump
can only be fitted in one position. - Tighten the
screws to the prescribed torque.
