Check of a state, removal and installation of a cover of a distributive chain, chain and its asterisks

Removal of a cover

 PERFORMANCE ORDER

  1. Disconnect a negative wire from the battery.
  2. Remove the fan, a casing of the fan and a pulley of the water pump (The head of the Cooling system, heating and air conditioning).
  3. Remove a damper of tortional fluctuations of a bent shaft (Section Replacement of a Forward Epiploon of a Bent Shaft).
  4. 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.
  5. 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.
  6. Separate a cover of a distributive chain from the engine. In case of need slightly tap it for release on perimeter the hammer with soft brisk. Temporarily to a zakuporta a case pallet opening rags in avoidance hit in it of garbage and foreign objects.
  7. Smooth out the interfaced surfaces of a cover of a chain and the block of the engine, having removed from them all traces of oil and material of old laying.

Check of a condition of a distributive chain

 PERFORMANCE ORDER

  1. Remove from a pin of a bent shaft a maslootrazhatel and establish into place a bolt of a damper of tortional fluctuations. Turn for a bolt a bent shaft so that one of the parties of a chain sagged.
  1. Remove from a pin of a bent 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 tortional fluctuations.
  1. Apply a basic tag on the block. Shake the sagged part of a chain here and there fingers, having measured course size. The difference between two extreme provisions ми makes chain deflection size. If the deflection exceeds size in 13 mm, replace a chain together with asterisks.

Removal of a distributive chain

 PERFORMANCE ORDER

  1. Combine distributive tags of asterisks.
  1. When the piston of the first cylinder is in the provision of VMT, index points on asterisks of a distributive chain (arrow) have to settle down the friend opposite to the friend.
  1. Remove a persistent finger of the camshaft, a spring, a bolt of fastening of an asterisk and its washer.
  1. Remove a persistent finger with a spring (shooter), then remove a bolt in the center of an asterisk of the camshaft - insert the 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.
  1. Remove asterisks of cranked and distributive shaft assembled with a chain.

Do not allow a provorachivaniye of shaft after removal of a distributive chain.


  1. Removal and installation of a distributive chain is made assembled with asterisks.

Installation

 PERFORMANCE ORDER

  1. Track that the spline of a bent shaft was still turned up. Remember locations of the directing pin of the camshaft and a reciprocal opening in a shaft asterisk.
  1. Pay attention that on the party of an asterisk of the camshaft turned to the engine there is an opening (shooter).

... which is put on the directing pin (shooter) of a shaft - at installation track combination of an opening and pin.

  1. Enclose asterisks in a chain, having arranged distributive tags on one line and turned outside. Install assembly on the engine so that the line passing through tags crossed also the centers of asterisks.
  2. Establish a bolt of an asterisk of the camshaft and tighten it with the required effort. Establish into place a persistent finger and a spring.
  3. For check of correctness of installation of a distributive chain turn a bent shaft so that the distributive tag of an asterisk of the camshaft fell into a state for one hour. At the same time the tag of an asterisk of a bent shaft in the place where the next tooth enters gearing with a link of a chain has to fall into a state for three hours. Between tags exactly 15 fingers of a joint of links of a chain have to find room.
  1. For check of correctness of installation of assembly of a chain turn a bent shaft clockwise so that distributive tags of asterisks of a chain appeared in the provisions shown in the drawing and count the number of fingers of a joint of the links of a chain which are finding room between tags.
  1. Establish on a pin of a bent shaft a maslootrazhatel, having placed it the concave party from the engine.
  2. Grease both parties of new laying of a cover of a distributive chain with RTV sealant and apply laying to the block.
  3. Before installation of a cover into place make sure that integral laying of the pallet of a case is not damaged and is not deformed. In case of detection of defects of laying it needs to be replaced (The section Removal, check of a state 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).
  4. Grease both parties of new laying of a cover and corners of the pallet of a case and the block with RTV sealant, then install new laying on the block. Sealant will temporarily record laying.

If the pallet of a case was removed for replacement of its laying, the forward cover should be established to the place of before pallet.

  1. Install a cover of a distributive chain on the block.
  2. For centering of a cover of a distributive chain use a damper of tortional fluctuations. Leave an old epiploon on the place as it can be damaged in the course of installation of a cover.
  1. For centering of a cover of a distributive chain in the course of its installation use a damper of tortional fluctuations.
  1. Establish bolts of fastening of a cover to the block and the pallet to a cover and tighten them with the required effort.
  2. Replace a forward epiploon of a bent shaft (Section Replacement of a Forward Epiploon of a Bent Shaft).
  3. Having inserted a spline into a pin of a bent shaft, establish a damper of tortional fluctuations (Section Replacement of a Forward Epiploon of a Bent Shaft).
  4. You make installation of the remained components as it should be, the return to a removal order.
  5. Start the engine and check it for leaks.
