2. Turn the crankshaft and align the white notch on the crankshaft pulley with the arrow on the lower cover.
3. Remove the cylinder head cover and top cover.
4. Remove the power steering pump, air conditioning compressor and alternator drive belts.
5. Remove the crankshaft pulley and lower cover.
6. Remove the timing belt.
7. Remove the drive pulley.
8. Remove the oil pan and coarse oil filter.
9. Remove the oil pump.
10. Remove the screws from the pump body, then separate the body and cover.
11. Check the radial clearance between the internal and external gears of the oil pump. If the clearance exceeds the wear limit, replace the internal and external gears.
Radial clearance between internal and external gears:
- Standard (new): 0.02-0.14 mm
- Limit: 0.20 mm
12. Check the axial clearance between the housing and the oil pump gear. If the clearance exceeds the wear limit, replace the gear assemblies and/or the pump housing.
Axial clearance between housing and gear:
- Standard (new): 0.03-0.08 mm
- Limit: 0.15 mm
13. Check the radial clearance between the housing and the outer gear of the oil pump. If the clearance exceeds the wear limit, replace the gear assemblies and/or the pump housing.
Radial clearance between housing and outer gear:
- Standard (new): 0.10-0.18 mm
- Limit: 0.20 mm
14. Inspect both gears and the pump housing for scoring or other damage. Replace components as necessary.
15. Remove the old oil seal from the oil pump.
16. Using the special tool, carefully press in the new seal until the mandrel contacts the pump.
Note: The seal itself can be replaced without removing the oil pump.
17. Assemble the oil pump by applying locking compound to the threads of the pump housing screws.
18. Make sure the oil pump rotates freely.
19. Apply a thin layer of oil to the lip of the oil seal.
20. Install both reference pins and a new O-ring onto the oil pump.
21. Apply sealant to the contact surface of the cylinder block on the oil pump side.
Note:
- Use sealant P/N 08С70-К0234М, 08С70-К0334М or 08С70-X0331S.
- Before applying sealant, ensure that the contact surfaces are clean and dry.
- Apply the sealant evenly, distributing it over the entire contact surface.
- To prevent oil leakage, apply sealant to the threads of the bolt holes.
- Do not install components if more than five minutes have passed since applying the sealant. Instead, reapply the sealant, removing any traces of the old one.
- After assembly, wait at least 30 minutes before adding oil to the engine.
22. Install the oil pump on the cylinder block. Apply grease to the lip of the pump oil seal. Then install the oil pump on the crankshaft. After installing the pump, remove excess grease from the crankshaft, then make sure the oil seal is not deformed.
23. Install the coarse oil filter.
24. Install the oil pan.
