Removal and installation
1. Remove the oil pan (see section "oil pan").
A) Turn away bolts and nuts of fastening of the pallet.
b) Insert the blade of the special tool between the oil pan and the cylinder block and, cutting off the sealant, remove the pan.
2. Remove the oil receiver and the oil receiver gasket.

1. Remove the male and female rotors.
2. Installation is made in an order, the return to removal.
Examination
1. Check pressure reducing valve.
After lubricating the surface of the valve with fresh engine oil, install it in the mounting hole and make sure that the valve drops under its own weight.
If it doesn't, replace the valve or the entire oil pump.
2. Check the oil nozzle. Check that the oil nozzle is not damaged or clogged.
3. Lubricate the male and female rotors with engine oil, install them in the pump housing and check that the rotors rotate smoothly.
4. Using a feeler gauge, measure the radial clearance between the male and female rotor lugs.
- Nominal clearance - 0.06 -0.16 mm
- Maximum clearance - 0.26 mm
5. Using a feeler gauge, measure the radial clearance between the driven rotor and the pump housing.
- Nominal clearance - 0.03 - 0.09 mm
- Maximum clearance - 0.15 mm
6. Using a precision ruler and feeler gauge, measure the end clearance between the rotors and the housing wall.
- Nominal clearance - 0.10 -0.14 mm
- Maximum clearance - 0.30 mm
If either gap is greater than maximum, replace both rotors. Replace the entire pump if necessary.
