Clean the oil channels. Carefully check the condition of the gland seals in the front cover, replace if necessary. Check for wear and traces of sticking on the rollers.

Installation

1. Check the pressure reducing valve plunger for wear. Install in the front cover, aligning the marks.

2. Lubricate and reinstall the pump gears, matching the marks.

3. Install the pump cover and tighten the bolts to 21 Nm.



4. Install the rollers carefully without damaging the bearings (1 - plug; 2 - screwdriver).

5. Put drift MD 998285-01 on the crankshaft.


6. Install a new gasket, install the front cover and tighten the bolts.

7. Fix the left roller with a screwdriver, tighten the bolt with a torque of 35 Nm.



8. Install the filter bracket, tighten the cover and bracket bolts to 23 Nm 9 (1 - cap).

9. Put the cap on the left shaft.

10. Assemble the pressure reducing valve, tighten the plug to 45 Nm.

11. Install the oil receiver, pan and oil filter.

12. Install sprockets, toothed belts and adjust their tension (see subsection 3.4.29).

2.6L engine

Removing

1. Remove both chains and sprockets (see subsection 3.4.30).

2. Drain the oil and remove the filter.

3. Disconnect the bypass valve and oil cooler hoses on the bracket.
