The prevention

If the cover acts in film without infringement of fastening and integrity of consolidation of a head of cylinders after assemblage the weak leak of oil from under a lining established between a cover and a head of cylinders is possible. Therefore cover removal is expedient for combining with removal of a head of cylinders and lining replacement.


Removal

PERFORMANCE ORDER
1. Remove the pump of a cooling liquid (cм. Subsection 4.7).
2. Remove a pulley коленвала (cм. Subsection 3.1.1.5).
3. Remove the oil pallet and маслоприемник with the filter of rough clearing (cм. Subsection 3.1.1.12).
4. Turn away two bolts of fastening of an arm of the pump of the hydraulic booster to a cover of a chain drive, a nut and bolts of fastening of an arm to the pump and remove an arm.
5. Remove an arm from a support of the power unit, having turned away three bolts and having released conducting from collars on an arm.
6. Turn away bolts and nuts (are specified by arrows) and remove a viewing cover of gear wheels газораспределительного the mechanism on the right side of a head of the block of cylinders. Remove a lining.
7. Turn away two bolts and get натяжитель the bottom chain. Remove a lining натяжителя, having paid attention to its orientation.

The prevention

At removal натяжителя chains rotation коленвала is not supposed.


8. Turn away four bolts of fastening of a head of cylinders to the top part of a cover of a chain drive. On cars of early releases for access to one of bolts it is required to remove успокоитель the top chain.
9. Raise the engine a jack or will hang out on тали the lift, having hooked тали for special eyes on the engine.
10. Turn away a coupling bolt of the right support of the power unit, then turn away three bolts and remove a support. If rubber pillows of support have lagged behind a body arm remove also pillows.
11. Turn away bolts of fastening of an arm and a bolt of fastening adjusting скобы the generator to an arm. Remove an arm of the right support.
12. Turn away bolts of a cover of chains. Bolts have different length, therefore, it is necessary to mark their initial position.
13. Uncover a sock коленвала, then manipulating, get a cover from a motor compartment. Take уплотнители oil channels, it is necessary to replace them necessarily. If ослабли directing pins of a cover get them and store together with a cover.
14. Remove from a sock коленвала the shaped plug of a leading gear wheel of the oil pump.

Installation

PERFORMANCE ORDER
1. Before installation it is recommended to replace an epiploon коленвала.
2. Запрессуйте a new epiploon against the stop in a fillet. Запрессовывать оправкой, resting only in an external edge of an epiploon.
3. Be convinced that condensed surfaces of a cover and the block of cylinders pure and dry.
4. Insert into oil channels of the block of cylinders new sealing plugs.
5. Apply a thin film hermetic on a demountable surface (arrow) of a cover with the block of cylinders, hermetic put and on a site round the channel of the pump of a cooling liquid in the central part of a cover. If the head of cylinders did not act in film, put also hermetic and on the top plane of a cover.
6. Insert into the block of cylinders directing pins.
7. Combine a flute under шпонку in the plug of the oil pump with шпонкой, then dress the plug on a sock коленвала (arrows specify directing pins).
8. Bring a cover and expose a leading gear wheel of the oil pump so that the gear wheel has come on the shaped plug at cover installation into place. Dress a cover on коленвал, watching to damaging working edges of an epiploon, establish a cover on directing pins.
9. Wrap bolts of fastening of a cover in former apertures, tighten bolts in stages, gradually increasing the inhaling moment.
10. Wrap four bolts М6 of fastening of a head of the block of cylinders to a cover, tighten bolts with the set moment. On engines of early releases establish the top directing.
11. Establish a new lining on натяжитель the bottom chain, сориентировав it so that cut on a lining has been combined with a lubricant aperture натяжителя (it is specified by an arrow). Establish натяжитель with a lining and tighten bolts with the set moment.
12. Установитекронштейн the right suspension bracket of the power unit, tighten bolts with the set moment. Lay rubber pillows in a suspension bracket arm from outside bodies (if got), having convinced that pins of pillows have entered into apertures in an arm. Establish a support and tighten bolts with the set moment.
13. Combine the right support of the power unit with a body arm, insert a coupling bolt and tighten a nut with the set moment. Remove from the engine тали (or clean a jack).
14. Be convinced of cleanliness and absence of traces of a moisture and oil on condensed surfaces of a viewing cover of conducted asterisks of cam-shafts and heads of cylinders. If on a cover the lining replace a lining has been established, having established it on a head of cylinders. If consolidation was provided with hermetic put on all perimetre of a cover hermetic. Establish a cover and tighten bolts and nuts with the set moment.
15. Establish on the right support of the power unit an arm and tighten bolts of an arm with the set moment.
16. Establish on the engine the pump of the hydraulic booster of a wheel and tighten bolts of an arm of the pump.
17. Establish маслоприемник with the filter of rough clearing and the oil pallet (cм. Subsection 3.1.1.12).
18. Establish a pulley коленвала (cм. Subsection 3.1.1.5).
19. Establish the pump of a cooling liquid (cм. Subsection 4.7).
20. Fill the engine with oil and a cooling liquid.
