Condition check, removal and installation of a cover of a distributive chain, chain and its asterisks

Cover removal

 PERFORMANCE ORDER

    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 an air conditioning). Remove демпфер крутильных fluctuations of a cranked shaft (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 картера 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 clearing on perimetre a hammer with soft the brisk. Temporarily закупорьте a pallet aperture картера rags in avoidance hit in it of dust and extraneous subjects. Smooth out interfaced surfaces of a cover of a chain and the engine block, having removed with all of them traces of oil and a material of an old lining.

Check of a condition of a distributive chain

 PERFORMANCE ORDER

    Remove from a pin of a cranked shaft маслоотражатель and establish into place a bolt демпфера крутильных fluctuations. Turn for a bolt a cranked shaft so that one of the chain parties has sagged.
    Remove from a pin of a cranked shaft маслоотражатель, having paid attention that it is established by the concave party from the engine, then screw into place a bolt демпфера крутильных 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 positions 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

 PERFORMANCE ORDER

    Combine distributive labels of asterisks.
    When the piston of the first cylinder is in position ВМТ, 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 (marksman), then remove a bolt in the centre of an asterisk of a camshaft - insert a screw-driver into one of apertures in an asterisk for keeping of last from проворачивания in the course of bolt easing.
    Remove asterisks of cranked and distributive shaft in gathering with a chain.

Do not suppose проворачивания shaft after removal of a distributive chain.


    Removal and installation of a distributive chain is made in gathering with asterisks.

Installation

 PERFORMANCE ORDER

    Track that шпонка a cranked shaft on the former has been turned upwards. Remember sites of a directing pin of a camshaft and a reciprocal aperture in a shaft asterisk.
    Pay attention that on the party of an asterisk of a camshaft turned to the engine there is an aperture (arrow).

... Which is put on directing pin (arrow) of a shaft - at installation track aperture and pin combination.

    Enclose asterisks in a chain, having arranged distributive labels on one line and turned outside. Establish assemblage on the engine so that the line passing through labels crossed also the centres 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 has appeared in position at one o'clock. Thus the label of an asterisk of a cranked shaft in a place where the nearest tooth enters into gearing with a chain link should appear in position at three o'clock. Between labels should find room exactly 15 fingers of a joint of links of a chain.
    For check of correctness of installation of assemblage of a chain turn a cranked shaft clockwise so that distributive labels of asterisks of a chain have appeared in positions shown on drawing and count quantity of fingers of a joint of links of the chain which are finding room between labels.
    Establish on a pin of a cranked shaft маслоотражатель, having placed its concave party from the engine. Grease both parties of a new lining of a cover of a distributive chain with hermetic RTV and put a lining to the block. Before cover installation into place make sure that the integral lining of the pallet картера is not damaged and not deformed. In case of detection of defects of a lining it is necessary to replace it (Has undressed Removal, check of a condition and installation of the oil pump). It is supposed that the pallet lining картера will be replaced for a guarantee of prevention of occurrence of leaks (Has undressed Removal and pallet installation картера). Grease both parties of a new lining of a cover and pallet corners картера and the block with hermetic RTV, then establish a new lining on the block. Hermetic will temporarily fix a lining.

If the pallet картера acted in film for replacement of its lining, the forward cover should be established into place before the pallet.

    Establish a cover of a distributive chain on the block. For centering of a cover of a distributive chain use демпфер крутильных 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 take advantage демпфером крутильных 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 (Section Replacement of a forward epiploon of a cranked shaft). Having inserted шпонку into a pin of a cranked shaft, establish демпфер крутильных fluctuations (Section Replacement of a forward epiploon of a cranked shaft). Installation of the remained components make in an order, the return to a removal order. Start the engine and check up it on leaks.
