2.29. Repair of the oil pump

GENERAL INFORMATION

Prevention

At installation of the oil pump use a new sealing ring of a cranked shaft.


Dismantling

Unscrewing of screws of fastening of a back cover of the oil pump on the engine of 2,0 l

PERFORMANCE ORDER
1. Remove the oil pump.
2. Unscrew screws and uncover the oil pump (see fig. Unscrewing of screws of fastening of a back cover of the oil pump on the engine of 2,0 l).

Check

Gap measurement between teeths of rotors of the oil pump

Measurement of an axial gap of a rotor of the oil pump

Details of a safety valve of pressure on the engine of 2,0 l

PERFORMANCE ORDER
1. Using a marker, note arrange scientific research institute of an internal and external rotor of the oil pump.
2. Clear all details of the oil pump and check their condition.
3. Using an edge щупа, measure a gap between an internal and external rotor of the oil pump. Using металличес I forge a ruler, check an axial gap between the case of the oil pump and rotors (see fig. Gap measurement between teeths of rotors of the oil pump, Measurement of an axial gap of a rotor of the oil pump).
4. Unscrew a bolt of a safety valve of pressure from a forward part of the case of the oil pump and take a spring and a plunzher from the pump case (see fig. Details of a safety valve of pressure on the engine of 2,0 l).
5. Boots of natyazhitel should rotate freely on axes. If on them there are cracks, chips or considerable wear of a working surface, it is necessary to replace them.

Assembly

Use of an edge of a screw-driver for removal of an old sealing ring from the case of the oil pump

Use of a tubular opravka for installation of a new sealing ring of a cranked shaft on the engine of 2,0 l

PERFORMANCE ORDER
1. Replace the forward sealing ring of a cranked shaft located from the forward party of the case of the oil pump. Using a screw-driver edge, take an old sealing ring and, using a tubular opravka of the corresponding diameter, establish a new sealing ring (see fig. Use of an edge of a screw-driver for removal of an old sealing ring from the case of the oil pump, Use of a tubular opravka for installation of a new sealing ring of a cranked shaft on the engine of 2,0 l).
2. Check that interfaced surfaces of a back cover of the pump and the pump case pure and dry, then put on these surfaces a thin layer of hermetic (Opel No. 90485251) and establish a back cover on the pump. Screw in screws of fastening of a cover.
3. Establish the pump on the engine.
