Removal and installation of a belt of drive ГРМ (engines 1.4 and 1.6)

Start performance of procedures only after full cooling of the engine.

Removal

 PERFORMANCE ORDER

  1. Disconnect a negative wire from the battery.
  2. On the engine of 1.6 l separate a socket of the gauge-measuring instrument of weight of an air stream (MAF).
  3. Remove the air filter with a soaking up hose and an air inlet sleeve (see the Head of the Power supply system, release and decrease in toxicity of the fulfilled gases).
  4. Turn out bolts of fastening and remove the top cover of a gear belt.
  5. Remove a belt of a drive of auxiliary units.

On cars with К/В a belt only remove from a pulley, but do not take out it.

  1. Remove spark plugs (see the Head of Adjustment and car routine maintenance).
  2. Turn out two bolts of fastening of the gauge of position of a camshaft (CMP) (1) and take him aside together with the attached electroconducting.

The scheme of an arrangement of adjusting labels ВМТ

  1. Remove the right forward wheel. If necessary remove локер a wheel arch. At presence in a design of the engine of an oil bath uncover a flywheel (the Manual 5-step box of a gear change see the Head).
  2. Establish the piston of 1st cylinder in position ВМТ (the Section of Procedure of repair of petrol engines DOHC without their extraction from the car see).
  3. Remove a pulley of a cranked shaft. Thus watch that earlier established position of a shaft did not change. For deduction of a shaft from проворачивания block it.
  4. Remove the bottom cover of a gear belt.
  5. If it is supposed to use a gear belt repeatedly, mark on it with an arrow a direction of its movement (clockwise).
  6. Ослабьте a tension of a gear belt, for what ослабьте a fixing bolt of a tension roller. If necessary turn a tension roller a key-shestigrannikom for the clown in an hour hand direction.

Easing of a tension of a belt of drive ГРМ

  1. Remove a gear belt and check up its condition.

Engine position at the removed gear belt do not change.

Installation and tension

Before installation check up, whether labels ВМТ (the Section of Procedure of repair of petrol engines DOHC without their extraction from the car see) on pulleys of camshafts, and also on a cogwheel of a cranked shaft coincide. Installation of a gear belt at incorrect position of cogwheels can lead поврежениям valves and engine pistons.


 PERFORMANCE ORDER

  1. Check up adjusting position of the water pump. The label (2) on the pump should coincide with a label (1) on the block of cylinders.

Adjusting labels of the water pump

  1. Put on a gear belt cogwheels, without turning the last. Thus necessarily watch correctness of packing of a belt.

The scheme of a lining of a gear belt
1 — the Cogwheel of a cranked shaft
2 — the Tension roller
3 — the Water pump
4 — the Intermediate roller, the release party
5 — the Cogwheel of an inlet camshaft
6 — the Cogwheel of a final camshaft
7 — the Intermediate roller, the admission party

At packing of a gear belt on a cogwheel of an inlet camshaft watch to passing any tooth and that the label during belt imposing coincided with the top edge of a head of cylinders.

  1. Pull a gear belt. For this purpose turn counter-clockwise a tension roller a key-shestigrannikom through the adjusting clown so that to reach the maximum tension. The index of a tension roller thus costs on the right, about a label. Fix in this position a tension roller of a gear belt.

Initial tension of a gear belt

At adjustment of a tension of a gear belt its part between an intermediate roller from outside release and a cogwheel of a cranked shaft should be tense, otherwise exact adjustment is impossible.

  1. Screw an old bolt of fastening of a pulley of a cranked shaft. Smoothly, without jerks, turn a cranked shaft by hand on 2 turns clockwise. Then check up, whether labels on cogwheels of camshafts and on a cogwheel of a cranked shaft coincide. In case of discrepancy remove a belt and repeat adjustment.
  2. Adjust a tension of a gear belt. For this purpose it is a little ослабьте an adjusting bolt of a tension roller of a gear belt also turn the adjusting clown in an hour hand direction so that index position corresponded to accompanying illustrations.

Adjustment of a new gear belt
And — the Index (1) tension rollers of a gear belt should coincide with a label (2)
In — the Index (1) tension rollers of a gear belt should coincide with a label (2) «NEW»

Adjustment of already used gear belt
And — the Index (1) tension rollers of a gear belt should coincide with the left edge of a label (2)
In — the Index (1) tension rollers of a gear belt should coincide with a label (2) «USED»

Adjusting labels can differ depending on a year of release of the car. The specified values operate also for adjustment of a tension of a gear belt within the limits of maintenance service carrying out.

  1. Tighten an adjusting bolt of a tension roller with effort of 20 Nanometers.
  2. Establish the bottom cover of a gear belt.
  3. Establish a cogwheel of a cranked shaft. Thus it is necessary to apply a new bolt always. At first tighten a bolt with effort of 95 Nanometers, and then tighten its rigid key on a corner 30 hailstones. And on a corner 15 hailstones.
  4. Fix the gauge of position of a camshaft on a back cover of a gear belt two bolts, having tightened them with effort of 8 Nanometers. Preliminary grease a carving of bolts with hermetic.
  5. The further installation is made in an order, the return to an order of removal of components.
