Procedures of repair of petrol engines DOHC without their extraction from the car

Reduction of the piston of the first cylinder in position of the top dead point of a step of compression (ВМТ)

The general information

Reduction of the piston of the first cylinder in position of the top dead point of a step of compression (ВМТ) see.

Order of performance of procedure

All engines

Reduction of any of pistons in position ВМТ is made by проворачивания a cranked shaft of the engine. If to take a detached view of the engine of drive ГРМ, the direction clockwise will be a normal direction of rotation of a cranked shaft. Remember that attempt проворачивания a shaft counter-clockwise can lead to infringement of adjustments of phases газораспределения. The first is the cylinder, extreme from outside drive ГРМ.

 PERFORMANCE ORDER

  1. Disconnect a negative wire of the accumulator. For the purpose of simplification проворачивания the engine turn out all spark plugs.
  2. For the purpose of providing of access to label ВМТ on cogwheels of camshafts, uncover drive ГРМ (Removal and installation of a cover of drive ГРМ see).

Engines 1.4, 1.6 and 1.8 l


The scheme of an arrangement of adjusting labels of cogwheels distributive (1) and cranked (2) shaft in position ВМТ of the end of a step of compression of the piston of the first cylinder (engines 1.4, 1.6 and 1.8)



 PERFORMANCE ORDER

  1. By means of the key which has been put on a bolt of fastening of a pulley of a cranked shaft, turn last in a direction of normal rotation before deployment of cogwheels of camshafts by adjusting labels to each other. The label on a rim of a cogwheel of a cranked shaft thus should be combined with a label on the case of the oil pump (the Scheme of an arrangement of adjusting labels of cogwheels distributive (1) and cranked (2 see an illustration) shaft in position ВМТ of the end of a step of compression of the piston of the first cylinder (engines 1.4, 1.6 and 1.8.

At performance of the listed conditions the engine will be resulted in position ВМТ of the end of a step of compression of the piston of the first cylinder.

Engines of 2.0 l

 PERFORMANCE ORDER

  1. By means of the key which has been put on a bolt of fastening of a pulley of a cranked shaft, turn last in a direction of normal rotation before combination of adjusting labels of cogwheels of camshafts with reciprocal risks on a cover газораспределительного the mechanism. The label on a rim of a pulley of a cranked shaft thus should be combined with the index on the case of the oil pump.

At performance of the listed conditions the engine will be resulted in position ВМТ of the end of a step of compression of the piston of the first cylinder.
