4.4.4. Removal and installation of a belt of the GRM drive

Removal of a gas-distributing belt has to be made on the cold engine!

Do not turn the engine at the taken-off gas-distributing belt!

Removal

 PERFORMANCE ORDER

  1. Disconnect a negative wire from the battery.
  2. Remove the air cleaner.
  3. Cock the parking brake, a front of the car and establish to a poddomkratta it on props. Remove the right forward wheel.
  4. Mark with chalk or paint the direction of rotation of a belt of the drive of auxiliary units. Having taken away to a natyazhitel by means of a cap key, weaken a belt and remove it from the engine (see the Head Nastroyki and routine maintenance of the car).
  5. Remove the top section of a cover of the GRM drive (see the Section Removal and installation of a cover of the GRM drive).
  6. Establish a bent shaft in the provision of VMT of the first cylinder (see the Section of the Procedure of repair of petrol SOHC engines without their extraction from the car) and do not change this situation.
  7. Remove a pulley of a bent shaft (see the Section Removal and installation of a pulley of a bent shaft).
  8. Remove the lower section of a cover of the GRM drive (see the Section Removal and installation of a cover of the GRM drive).
  9. If it is supposed to establish an old gear belt, mark with a felt-tip pen the direction of its movement (clockwise).
  10. Weaken a belt tension. For this purpose wring out a tension roller (1) so that openings in its mobile element (3) and in a plate coincided (2). Record a tension roller of a gear belt in the received situation a suitable core.

Fixing of a tension roller of a belt of the GRM drive.

  1. Take off a gas-distributing belt.

Do not rotate shaft at the taken-off belt.

Installation

 PERFORMANCE ORDER

  1. Make sure of correctness of combination of adjusting tags (address illustrations).
  2. Having begun with a cogwheel of a bent shaft and moving against an hour hand, establish a gas-distributing belt according to the scheme of laying. Track that the belt was tense on sites between the next wheels.

If the old belt is established, you watch the direction of its movement.

Scheme of laying of a belt of the GRM drive

  1. Take a lock core from a natyazhitel and weaken bolts of fastening of assembly of the water pump.
  2. Pull a gear belt by turning of the water pump by means of the KM-421-A tool so that the mobile element (1) of a tension roller (2) was opposite to the right emphasis. If there is no specified tool, it is possible to apply a suitable wrench (about 42.5 mm).

Adjustment of a tension of a gear belt, stage 1

  1. Turn a bent shaft on two whole revolutions clockwise and achieve the correct combination of adjusting tags of VMT.

Turn a bent shaft smoothly not to break position of the water pump.

  1. Pull a gear belt by turning of the water pump counterclockwise a little so that the index (1) and a tag on a plate of a tension roller (2) coincided.

Adjustment of a tension of a gear belt, stage 2

  1. Tighten bolts of fastening of the pump with the required effort (8 Nanometers).
  2. Screw all bolts of fastening of a pulley of a bent shaft. Remove the fixing mandrel and turn by hand a shaft on two turnovers of the direction of an hour hand. In conclusion check whether are opposite to each other of a tag of pulleys of cranked and distributive shaft.
  3. Check a tension of a gear belt: the index of a mobile element of a tension roller has to coincide with a plate. Otherwise it is necessary to repeat adjustment.

If at installation it is required to weaken a tension of a gear belt, press a hand finger on a natyazhitel so that openings coincided (3).

  1. In this situation enter a suitable core into openings. Thus, the natyazhitel is fixed and the belt can be taken off.
  2. Working as it should be, the return to a dismantle order, install the removed components on the places.
  3. At installation of the air filter check and if necessary replace its filtering element.
  4. Screw a bolt of a pulley of a bent shaft and tighten it with the required effort.
  5. On the C14NZ engine check and if necessary adjust ignition.
