Check

Pulleys, pulley of the mechanism of a tension of a gear belt and single pulley

 PERFORMANCE ORDER

  1. Check pulleys of distributive and cranked shaft, a pulley of the mechanism of a tension and a single pulley for lack of uneven wear, cracks and damages. Replace them as required.
  2. Check ease and smoothness of rotation of a pulley of the mechanism of a tension and single pulley, and also lack of extraneous noise at rotation. Replace them as required.
  1. Replace pulleys if there is a lubricant leak.

Gear belt

 PERFORMANCE ORDER

  1. Check a gear belt on lack of traces of oil, water or dust. If it is necessary replace a belt. Insignificant traces have to be wiped by dry fabric or paper. You do not clean a gear belt solvent.
  2. After repair of the engine or adjustment a belt tension, check a condition of a belt. With the following defects, replace a gear belt.

    • Strongly do not bend a gear belt and do not change the direction of its rotation.
    • Do not allow oil and lubricant to contact with a gear belt as it will lead to its destruction.


Description
Defect
1. Rigid return surface of a gear belt

The surface has a glossy appearance. Rigidity of a surface such is that the nail does not leave marks on a belt

2. Cracks on the return surface of a gear belt
3. Cracks or stratification of a gear belt
4. Strongly worn-out teeths

The side of tooth is worn-out, at the same time fibers, a cord and the rubber basis become visible

5. Strongly worn-out teeths (last stage)

The side of tooth is worn-out, at the same time attritions become visible and tooth thickness is reduced

6. Cracks in the basis of teeths
7. Lack of tooth
8. Strong wear of one party of a belt

The normal belt has to have an equal side end face as though cut off by a sharp knife

9. Cracks on lateral face of a gear belt

Installation

L engines 1,8 and 2,0

 PERFORMANCE ORDER

  1. Install the plug, and a pulley of a bent shaft as shown in the drawing. Pay attention to the direction of their Inhaling Moment installation: 170–180 N • m.
  1. Establish a pulley of the camshaft and fix by a bolt, having tightened it the required moment. Inhaling moment: 100–120 N • m.
  2. Combine adjusting tags on pulleys of distributive and cranked shaft with indexes, at the same time the piston of the first cylinder has to be installed in VMT in a compression step.
  3. Install the mechanism of a tension of a gear belt and the directing roller.
  1. Establish a gear belt on a camshaft pulley.

After installation of a gear belt on a camshaft pulley, pressing a pulley of the mechanism of a tension of a gear belt of the drive to the water pump be convinced that its sagging from a tension is excluded.

  1. Turn clockwise a bent shaft of the engine on one turn and combine a tag on a pulley of a gear belt of a bent shaft with the index on the block of cylinders of the engine. Check that the tag on a pulley of the camshaft was combined with the index on a cover of a head of cylinders.

Do not turn a bent shaft of the engine counterclockwise. The moment of an inhaling of bolts of fastening of the mechanism of a tension and the directing roller: 43–55 N • m.

  1. Repeatedly check a tension of a gear belt. When pressing the tense branch of a gear belt by effort of 20 N the belt has to cave in approximately on 4–6 mm.
  1. Establish casings of a gear belt. Inhaling moment: 8–10 N • m.
  1. Establish a pulley of a bent shaft. Inhaling moment: 140–150 N • m.
  1. Establish a pulley of the water pump.
  1. Establish poliklinovy a belt and adjust its tension.

Engines of 1,6 l

 PERFORMANCE ORDER

  1. Install the plug, and a pulley of a bent shaft as shown in the drawing. Pay attention to the direction of their Inhaling Moment installation: 140–150 N • m.
  1. Establish a pulley of the camshaft and fix by a bolt, having tightened it the required moment. Inhaling moment: 80–100 N • m.
  2. Establish the directing roller and fix by a bolt, having tightened it the required moment. Inhaling moment: 43–55 N • m.
  1. Combine adjusting tags on pulleys of distributive and cranked shaft with indexes, at the same time the piston of the first cylinder has to be installed in VMT in a compression step.
  1. At installation of the mechanism of a tension of a gear belt first of all install the tension mechanism, a spring and the expansion plug. Temporarily tighten bolts. Then, temporarily squeeze the tension mechanism, having inserted a bolt into the extended opening. Establish the back end of a flat spring opposite to a forward cover, as shown in the drawing.
  1. Fix the tension mechanism which is taken away to the water pump.
  1. Establish a gear belt on a pulley of a bent shaft.
  1. Establish a gear belt on a camshaft pulley, at the same time be convinced that its sagging from a tension is excluded.
  1. Tighten bolts of fastening of the mechanism of a tension.
  2. Turn clockwise a bent shaft of the engine on one turn and combine a tag on a pulley of a gear belt of a bent shaft with the index on the block of cylinders of the engine. Check that the tag on a pulley of the camshaft was combined with the index on a cover of a head of cylinders. Moment of an inhaling of a bolt of fastening of the mechanism of a tension: 20–27 N • m
  1. Repeatedly check a tension of a gear belt. When pressing the tense branch of a gear belt by effort of 49 N the gear belt has to cave in to the center of a head of a bolt of fastening of the mechanism of a tension.
  1. Establish casings of a gear belt. Inhaling moment: 8–10 N • m.
  1. Establish a pulley of a bent shaft. Make sure that the pin of a bent shaft enters a pulley opening. Inhaling moment: 140–150 N • m.
  2. Establish a belt of the drive of the fan and adjust its tension.
  3. Establish a pulley of the water pump.
  4. Establish poliklinovy a belt and adjust its tension.
