Jeep Grand Cherokee

Disconnect a negative wire from the battery. Result the piston of the first cylinder of the engine in position ВМТ (Has undressed Reduction in position ВМТ of the piston of the first cylinder). Keeping the piston on a compression step, establish it in position approximately 30 before ВМТ. Uncover the distributor (the Head of Adjustment and routine maintenance). For maintenance of desirable accuracy of check to turn a cranked shaft follows manually, very slowly by means of a semiinch drive with a collar, connected to the replaceable face head of the demanded big diameter which has been put on the big bolt in the centre of a pulley of a shaft. Slowly turn a cranked shaft clockwise until the piston of the first cylinder will not move to position ВМТ. Thus the left part of a distributive chain should sag. Do not turn a shaft further, but also do not return it back. Mark on the distributor case its position бегунка. Slowly turn a shaft counter-clockwise before movement occurrence бегунка the distributor. Stop and by position of labels of an advancing of ignition (distributive) check up as far cranked shaft has left from position ВМТ of the piston of the first cylinder. If the label has moved more than on 10 , the distributive chain is worn out excessively. For more exact check uncover chains.

Disconnect auxiliary units (such as the pump of system of hydrostrengthening of a wheel, the generator and the compressor of the conditioner of air), limiting access to a cover of a distributive chain. Leave hoses connected to the compressor of the conditioner and the pump of the hydraulic booster and fix units aside (Has undressed Removal and installation of the inlet pipeline). Remove an arm of hinged units from a forward wall of the engine.

Remove the water pump (the Head of System of cooling, heating and an air conditioning). Give two forward bolts of the pallet картера, screwed in in a chain cover - to reach bolts most easier from under the car.

Give the remained fixing bolts and separate a cover of a distributive chain from the block and the pallet картера. The cover can appear "become attached" to the block. In this case follows with the help шпаклевочного a knife to destroy a hermetic layer between interfaced surfaces. Do not try to separate AT ALL a cover by means of the lever - it easily to damage!

Remove from a pin of a cranked shaft an oil separator (if that is provided). Remember how the oil separator has been established on a shaft - at assemblage its position should not be changed. It makes sense at the given stage to replace a forward epiploon of a cranked shaft (Section Replacement of a forward epiploon of a cranked shaft).

Put on a bolt of an asterisk of a camshaft a replaceable face head in structure динамометрического a key and put to a shaft a twisting moment in a direction of normal rotation (if heads of cylinders with коромыслами are left on the engine, the moment should make 41 Н•м if are removed - 20 Н•м). Do not suppose проворачивания a shaft! By means of a ruler fix position стыковочного a finger of a link of a chain on an asterisk and replace a twisting moment direction. Define displacement size on a ruler and estimate the general moving of a chain. If displacement makes more than 3 mm, it is necessary to replace a chain.

Check of an asterisk of knee and distributive shaft on presence of damages and deterioration signs.

Make sure of combination of distributive labels and give a bolt of an asterisk of a camshaft.

Combine distributive labels of asterisks of distributive and cranked shaft.

Asterisks of distributive and cranked shaft can be removed by means of three- or двухзахватного a stripper...

... Or two screw-drivers

Replacement of a distributive chain is made in the complete set with asterisks. Installation of a new chain on old asterisks is inadmissible. Having combined шпоночный a groove with шпонкой, put on an asterisk a shaft pin, запрессовав it into place by means of a bolt демпфера крутильных fluctuations with the big washer put on it. For bolt rotation take advantage of a replaceable head with a drive. It is alternatively possible to begin to knock accurately an asterisk on a pin a hammer.

In case of occurrence of resistance landing of an asterisk to a shaft should not apply force is though can lead to asterisk putting on, however it is fraught with imperceptible damage of components which in the future is capable to develop, having caused serious breakage of the engine.

At combination of distributive labels of asterisks in position ВМТ there is a piston of the sixth cylinder.

Establish an asterisk of a camshaft with the chain put on it on the place on a shaft pin, preliminary having turned its distributive label (marksman) downwards.

Шпонка a camshaft should be combined with a groove under it in an asterisk turned by a distributive label at 6 o'clock (downwards).

Try not to scratch a wall of a nest of an epiploon and not to leave on them задиров and agnails. Begin to knock a new epiploon in a cover by means of a hammer and a replaceable head of the corresponding size.

If the pallet acted in film for lining replacement, establish a forward cover (a cover of a distributive chain) engine before to establish into place the pallet with its lining.
