Removal, installation and service of the oil pump
|
|
This procedure is among those which performance does not demand removal of the engine from the car. |
Removal
|
|
Empty cooling system (see. Head Current leaving and service).
Disconnect a negative wire from the battery.
Merge impellent oil (see. Head Current leaving and service).
Remove a belt of a drive of GRM (see. Head Current leaving and service).
Remove the case pallet, a maslozabornik and a maslootrazhatel (see. Section Removal and installation of the pallet of a case).
Turn out two bolts of fastening of the steering pump and four bolts of fastening of its basic arm.
Remove the steering pump assembled with a basic arm.
Remove from a cranked shaft a cogwheel of a drive of GRM, - in case of need use a stripper intended for dismantle of a steering wheel.
Turn out four remained fixing bolts and remove assembly of the oil pump.
|
|
Remove from pump assembly a sealing ring (1).
|
|
|
Installation
|
|
Establish on pump assembly the NEW sealing ring.
|
|
Impose on an interfaced surface of pump assembly a continuous pillow of hermetic.
|
Establish the pump on the engine and fix it four bolts, having tightened the last with demanded effort (bolts And: 22 Nanometers, bolts In: 44.5 Nanometer).
Turn out two bottom, then two top bolts of fastening of the К/В compressor.
Release three bolts of fastening of a basic arm of the К/В compressor.
Establish a basic arm of the steering pump and fix it four bolts, having tightened them manually.
Tighten three bolts of fastening of basic arm К/В.
Establish into place the To/in compressor, having manually tightened bolts of its fastening.
Tighten bolts of fastening of the compressor (at first top, then bottom) with demanded effort (23.5 Nanometers).
Tighten with demanded effort (32.4) bolts of fastening of a basic arm of the steering pump.
Establish the steering pump and fix it two bolts, having tightened the last with demanded effort (57.5 Nanometers).
Establish into place a cogwheel of a cranked shaft, having tightened a big central bolt with demanded effort (162 Nanometers).
Further installation is made as it should be, the return to an order of dismantle of components. Do not forget about need of observance of requirements of Specifications of Head the Engine to efforts of a tightening of carving fixture.
Fill in in the engine fresh engine oil.
Start the engine and check it on existence of signs of development of leaks through joints of the established components.
In summary check correctness of installation of a corner of an advancing of ignition, in case of need make the corresponding adjustment (see. Head of System of electric equipment of the engine).

Service
|
|
Remove assembly of the oil pump.
|
|
Dismantling
Design of the oil pump
|
|
Transfer pump assembly on a workbench, turn out seven fixing screws and uncover (1).
Take internal (3) and external (2) rotors.
Take a lock ring and remove components of the reduktsionny valve (a saddle, a spring and a plunzher).
Take an epiploon (5), - the epiploon is subject to replacement without fail (see. Section Replacement of epiploons of a cranked shaft).
|
|
Check
|
|
Attentively examine the case and a pump cover, in case of identification of cracks, deformations and other mechanical damages replace defective components.
Estimate degree of wear of a plunzher of assembly of the reduktsionny valve, in case of need make its replacement.
Check a condition of a spring of klapanny assembly, in case of detection of defects make replacement. Measure free length a spring, - if the result of measurement exceeds value of 45.5 mm, the spring also is subject to replacement.
Make control measurements:
|
|
Measure size axial люфта rotors;
|
|
|
Measure gap size between tops of teeths of rotors;
|
|
|
Measure size люфта landings of an external rotor in the working chamber of the case.
|
Compare results of measurements to requirements of Specifications of Head the Engine, in case of need make the corresponding replacements.
|
|
Assembly
|
|
Installation is made as it should be, the return to an order of dismantle of components. Before landing in pump assembly grease the NEW epiploon with pure impellent oil. The cover is put on the case through hermetic. Track, that fixing screws were tightened with demanded effort (7.5 Nanometers).
