 PERFORMANCE ORDER

  1. To check axial люфт a cam-shaft. Demanded value:
    • VZ engines, В6 (SOHC): 0, 04 — 0, 13 mm
    • (SOHC) VR engines: 0, 06 — 0, 20 mm
    • VZE engines, В5, B6E: 0, 05 — 0, 18 mm
  2. If values do not correspond to requirements, it is necessary to replace a persistent plate and, probably, also a cam-shaft.
  1. Holding a cam-shaft a key, to unscrew a bolt of fastening of a cogwheel of a cam-shaft. To remove a cogwheel, if necessary to bring down in easy blows of a rubber hammer.

To remove a cogwheel of a cam-shaft carefully, not to lose directing pin.


  1. To unscrew a persistent plate and to take out a camshaft through a distributor opening.
  1. To beat out an old epiploon of a cam-shaft by means of a drift.

The place of landing of an epiploon should not be thus damaged.

Installation

 PERFORMANCE ORDER

  1. To grease a place of landing and a cam-shaft epiploon with a small amount of engine oil. Carefully to hammer an epiploon by means of a pipe of the same diameter into place. To hammer an epiploon so that it was level with a head of cylinders.

Epiploon at installation not to warp.

  1. To grease all places of a support of a cam-shaft with a small amount of engine oil.
  2. Carefully to insert a cam-shaft into a head of cylinders through a distributor opening.

At a vdviganiye the shaft should not warp. Carefully to move through an epiploon, not to damage a working edge.

  1. To establish a cam-shaft so that the press plate could enter into a cam-shaft groove. To screw a persistent plate with effort of 10 Nanometers.
  2. To insert into a cam-shaft directing pin. To establish a cam-shaft wheel so that the directing pin entered into gearing with a groove.
  3. Holding a cam-shaft a key to screw a cam-shaft cogwheel with effort of 60 Nanometers.

When keeping a shaft not to damage a head of cylinders a wrench.

  1. To check, whether there are cranked and distributive shaft on labels of ignition of the 1st cylinder, if necessary to adjust, see. Section Removal and installation of camshafts.
  1. To tighten bolts of fastening of covers of bearings a dinamometrichesky key in the specified sequence. The inhaling of bolts should be carried out in two passes.
  • 1st pass: 15 Nanometers
  • 2nd pass: 25 Nanometers
  1. To clear a cam-shaft wheel of water and oil.
  2. To establish and pull a gear belt, see. Section Removal and installation of a gear belt of VZ engines, В5, B6 (SOHC), (SOHC) VR.
  3. If is available, to establish on a head of cylinders the mechanical fuel pump, see. Head Power supply system, carburetor, system of injection of fuel, Section Removal and installation/check of the fuel pump.
  4. If the engine is not equipped with hydraulic pushers, to check a gap of valves, see. Section Check/adjustment of a gap of valves.
  5. To establish a cover of a head of cylinders with laying, see. Section Removal and head installation cylinders/replacement of laying of a head of cylinders.
  6. To establish the air filter, see. Head Power supply system, carburetor, system of injection of fuel, Section Removal and installation of the air filter.
  7. To screw the holder of the battery with effort of 20 Nanometers.
  8. To establish the battery, see. Section Removal and battery installation.

Removal for the diesel engine 1, 7 of l

At the removed gear belt the wheel of a cam-shaft should not be turned, differently valves will encounter pistons.


 PERFORMANCE ORDER

  2. To unscrew a back casing of a gear belt.
  1. To remove springs of shaking levers.
  1. Замаркировать shaking levers that at installation it was possible to establish them on former places.
  2. To take out shaking levers from the places.
  1. To check axial люфт a cam-shaft. Demanded value: 0, 02 - 0,18 mm. The most admissible axial люфт: 0, 20 mm. If this value is exceeded, it is necessary to replace a cam-shaft and, probably, a head of cylinders.
  1. To unscrew a press plate-1-.
  1. To unscrew 3 basic arms - 2-cam-shaft and to remove together with a cam-shaft - 3-.
  2. To remove a forward basic arm from a cam-shaft and to take out an epiploon-4-by means of a screw-driver.

Installation

 PERFORMANCE ORDER

  1. To grease a place of landing and a cam-shaft epiploon with a small amount of engine oil. Carefully to hammer an epiploon by means of a pipe of the same diameter into place. To hammer an epiploon so that it was level with a head of cylinders.

Epiploon at installation not to warp.


  1. To clear surfaces of a prileganiye of basic arms of dirt and oil.
