2. Set the piston of the first cylinder to the TDC of the compression stroke (see Section 3).
3. Remove the cylinder head cover (see Section 4) and upper drive belt cover.
4. Remove the drive belt, crankshaft pulley and lower drive belt cover.
5. Remove the camshaft drive belt (see Section 7) and crankshaft gear pulley.
6. Remove the oil pan (see Section 13) and disconnect the oil pump downpipe assembly (it is fixed with three bolts).
7. Unscrew the oil pump from the front of the block.
8. Remove screws and remove pump cover.
Pic. 14.8 Removing the oil pump cover. The screws are installed with locking adhesive. May need an impact screwdriver
9. Measure the clearance between the inner and outer rotors with a feeler gauge. Compare your result with the data in the specification.

10. Check clearance between rotors and pump cover.
Pic. 14.10 Measuring the rotor/cover end clearance
11. Check clearance between outer rotor and pump housing. Check that the inner and outer rotors are installed correctly: you should see one small dimple on each rotor.

12. If the gaps exceed the allowable values, replace the oil pump.
13. Install a new seal in the pump housing (until it stops in the restrictive groove). Pack pump cavity with grease. Apply sealant to the mounting screws and attach the pump cover. Tighten the screws with the force specified in the specification.
Pic. 14.13 Assembly of the oil pump:
1 - plug; 2 - washer; 3 - seal; 4 - spring; 5 - glass; 6 - cotter pin; 7 - pressure reducing valve; 8 - cover; 9 - outer rotor; 10 - inner rotor; 11 - rubber ring; 12 - body.
14. When installing the pump, use only a new gasket and a rubber ring. The tightening torque of the mounting bolts is indicated in the specification.
Note: Lubricate the threads of the bolts with sealing paste to prevent leaks.

15. At installation of a reception pipe of the oil pump apply only new lining and a rubber ring.
16. Install the camshaft drive belt and everything else.
17. Check the oil level and top up if necessary. Start the engine and check for oil pressure and leaks.
18. Recheck the oil level after stopping the engine and 5 minutes pause.
