Condition check, removal and installation of a cover of a distributive chain, chain and its asterisks
Cover removal
|
- Disconnect a negative wire from the battery.
- Remove the fan, a casing of the fan and a pulley of the water pump (The head of System of cooling, heating and air conditioning).
- Remove a damper of krutilny fluctuations of a cranked shaft (The section Replacement of a forward epiploon of a cranked shaft).
- Remove the compressor of the conditioner of air and the generator and put aside, without disconnecting from them wires and hoses. Remove the arms fixed on a cover of a distributive chain.
- Give bolts of fastening of the pallet of a case to a cover of a distributive chain and bolts of fastening of a cover to the engine block.
- Separate a cover of a distributive chain from the engine. In case of need slightly обстучите it for release on perimeter a hammer with soft the brisk. Temporarily закупорьте an opening of the pallet of a case rags in avoidance hit in it of garbage and extraneous subjects.
- Smooth out interfaced surfaces of a cover of a chain and the engine block, having removed from them all traces of oil and a material of old laying.

|
Check of a condition of a distributive chain
|
- Remove from a pin of a cranked shaft a maslootrazhatel and establish into place a bolt of a damper of krutilny fluctuations. Turn for a bolt a cranked shaft so that one of the chain parties sagged.
|
- Remove from a pin of a cranked shaft a maslootrazhatel, having paid attention that it is established by the concave party from the engine, then screw into place a bolt of a damper of krutilny fluctuations.
|
- Put on the block a basic label. Shake the sagged part of a chain here and there fingers, having measured course size. The difference between two extreme situation ми makes size of a deflection of a chain. If the deflection exceeds size in 13 mm, replace a chain together with asterisks.
|
|
Removal of a distributive chain
|
- Combine distributive labels of asterisks.
|
- When the piston of the first cylinder is in situation VMT, index points on asterisks of a distributive chain (arrow) should settle down the friend opposite to the friend.
|
- Remove a persistent finger of a camshaft, a spring, a bolt of fastening of an asterisk and its washer.
|
- Remove a persistent finger with a spring (shooter), then remove a bolt in the center of an asterisk of a camshaft - insert a screw-driver into one of openings in an asterisk for keeping of the last from a provorachivaniye in the course of weakening of a bolt.
|
- Remove asterisks of cranked and distributive shaft assembled with a chain.
|
Do not allow a provorachivaniye of shaft after removal of a distributive chain. |
|
- Removal and installation of a distributive chain is made assembled with asterisks.
|
|
|
Installation
|
- Track that the shponka of a cranked shaft on the former was turned up. Remember locations of a directing pin of a camshaft and a reciprocal opening in a shaft asterisk.
|
- Pay attention that on the party of an asterisk of a camshaft turned to the engine there is an opening (shooter).
|
|
... which is put on directing pin (shooter) of a shaft - at installation track opening and pin combination.
|
- Enclose asterisks in a chain, having arranged distributive labels on one line and turned outside. Establish assembly on the engine so that the line passing through labels crossed also the centers of asterisks.
- Establish a bolt of an asterisk of a camshaft and tighten it with demanded effort. Establish into place a persistent finger and a spring.
- For check of correctness of installation of a distributive chain turn a cranked shaft so that the distributive label of an asterisk of a camshaft appeared in situation on one hour. Thus the label of an asterisk of a cranked shaft in a place where the next tooth enters into gearing with a link of a chain should appear in situation at three o'clock. Between labels 15 fingers of a joint of links of a chain should find room exactly.
|
- For check of correctness of installation of assembly of a chain turn a cranked shaft clockwise so that distributive labels of asterisks of a chain appeared in provisions shown in drawing and count quantity of fingers of a joint of links the chains which are finding room between labels.
|
- Establish on a pin of a cranked shaft a maslootrazhatel, having placed it the concave party from the engine.
- Grease both parties of new laying of a cover of a distributive chain with RTV hermetic and put laying to the block.
- Before cover installation into place make sure that integral laying of the pallet of a case is not damaged and not deformed. In case of detection of defects of laying it is necessary to replace it (The section Removal, check of a condition and installation of the oil pump). It is supposed that laying of the pallet of a case will be replaced for a guarantee of prevention of emergence of leaks (The section Removal and installation of the pallet of a case).
- Grease both parties of new laying of a cover and corners of the pallet of a case and the block with RTV hermetic, then establish new laying on the block. Hermetic will temporarily fix laying.
|
If the pallet of a case acted in film for replacement of its laying, it is necessary to establish a forward cover to the place of before pallet. |
- Establish a cover of a distributive chain on the block.
- For centering of a cover of a distributive chain use a damper of krutilny fluctuations. Leave an old epiploon on a place as it can be damaged in the course of cover installation.
|
- For centering of a cover of a distributive chain in the course of its installation use a damper of krutilny fluctuations.
|
- Establish bolts of fastening of a cover to the block and the pallet to a cover and tighten them with demanded effort.
- Replace a forward epiploon of a cranked shaft (The section Replacement of a forward epiploon of a cranked shaft).
- Having inserted a shponka into a pin of a cranked shaft, establish a damper of krutilny fluctuations (The section Replacement of a forward epiploon of a cranked shaft).
- Installation of the remained components make as it should be, the return to a removal order.
- Start the engine and check it on leaks.
