Removal

PERFORMANCE ORDER
1. Shoot belts and a video of a natyazhitel.
2. Remove the pallet.
3. Remove a crankshaft pulley. For access to the reducing valve uncover a chain.
4. Unscrew 9 screws (ukazna shooters) and remove the case of the oil pump.

7. Carefully disassemble the reducing valve.

Check

PERFORMANCE ORDER
1. Wash out all details in solvent, check existence of wear and damages.
2. Check a condition of the sliding surface of the piston of the reducing valve and a spring. At detection of damages replace the piston complete with a spring.
3. Check the probe a gap between the conducted rotor and the case.
4. Check the probe a face gap of a rotor between a rotor and a cover.
5. Check the probe a gap in gearing of the leader and conducted rotors.
6. Compare results of measurements to standard. If gaps exceed norm, then replace rotors in a set. If necessary replace a pump housing (a chain cover).

Installation

PERFORMANCE ORDER
1. Oil rotors for the engine and install in the case.
2. Put technical vaseline in a pump cavity, lay laying, put a cover and tighten screws.
3. Oil the piston of the reducing valve fresh for the engine and establish valve details.
4. Establish new laying of a cover of a chain on the directing pins.
5. Establish a chain cover, having entered the roller of the leading rotor of the oil pump into gearing with the leading gear wheel of the crankshaft.
