4.4.5. Removal and installation of cogwheels of the GRM drive

Camshaft cogwheel

Removal

 PERFORMANCE ORDER

  1. Take off a gas-distributing belt (see the Section Removal and installation of a belt of the GRM drive).
  2. Block the camshaft from a provorachivaniye at an otpuskaniye of the central bolt of its cogwheel. Manufacture of two pieces of steel plates (one long, and one short) and three bolts with nuts the bifurcate device for deduction of a wheel. Use one bolt as axial, fix two others on the ends of a fork, - they are entered into gearing with openings in a cogwheel. It is alternatively possible to uncover the gas-distributing mechanism (see the Section Removal and installation of a cover of the gas-distributing mechanism) and to hold a shaft Rozhkov a key for lysk.

Blocking of the camshaft from a provorachivaniye by means of a bifurcate clamp (it is alternatively possible to uncover the gas-distributing mechanism and to block a shaft for lysk Rozhkov a key)

  1. Turn out the central bolt and remove it from a shaft together with a washer. Remove a cogwheel. Check landing density in a pin of an adjusting pin of a wheel, - in case of need take a pin and move away him to the reliable place.

Installation

 PERFORMANCE ORDER

  1. Before installation check a condition of an epiploon of the camshaft. In case of identification of traces of leaks or signs of wear replace an epiploon (see the Section Replacement of an Epiploon of the Camshaft).
  2. Put a cogwheel on a shaft pin, - track correctness of hit of the fixing pin in a reception opening on a wheel.

When landing a cogwheel track hit of an adjusting pin in a reception opening

  1. Screw the central bolt with the washer which is put on it and tighten it with the required effort, holding a shaft from a provorachivaniye one of 2 ways described in the paragraph.

Tightening of the central bolt of fastening of a cogwheel of the camshaft (the shaft keeps from a provorachivaniye for lysk, - GRM is uncovered)

  1. Establish a GRM drive belt (see the Section Removal and installation of a belt of the GRM drive), then, - if removed, - establish a cover of the gas-distributing mechanism (see the Section Removal and installation of a cover of the gas-distributing mechanism).

Cogwheel of a bent shaft

Removal

 PERFORMANCE ORDER

  1. Take off a GRM drive belt (see the Section Removal and installation of a belt of the GRM drive).
  2. Remove a cogwheel from a pin of a bent shaft, - try to remember by what party the wheel was established.
  3. Check reliability of landing in the groove of a spline, - in case of need take a spline and move away her to the reliable place.

Installation

 PERFORMANCE ORDER

  1. If took, establish a spline in a groove in a pin of a bent shaft.
  2. Having tracked hit of a spline in a shponochny groove, put a cogwheel on a shaft pin VMT tag outside.
  3. Establish a GRM drive belt (see the Section Removal and installation of a belt of the GRM drive).
