4.12. Removal and installation of a chain of a drive of GRM

Components of installation of a chain of a drive of GRM

1 — the Forward cover of a head of cylinders
2/3 — the Asterisk of an inlet/final camshaft
4 — Natyazhitel of GRM chain
5 — the Lever of a natyazhitel of a chain of GRM
6 — the Forward cover of the block of cylinders
7 — the Forward epiploon of a cranked shaft
8 — the Pulley of a cranked shaft

9 — the Chain of a drive of GRM
10 — GRM Directing to a chain
11 — the Pin
12 — the Driving plug of the oil pump
13 — the Asterisk of a cranked shaft
14 — the Sealing ring

On models from RKPP remove the power unit and separate the engine from RKPP (see. Section Removal and installation of the power unit). Then remove the components specified in point 3 and pass to point 5.

Removal

 PERFORMANCE ORDER

  1. Remove the right forward wheel and a loker of the right forward wheel arch.
  2. Lower impellent oil (see. Head of Control and routine maintenance of the car).
  3. Remove the following components:
  4. Fix the engine, having established on it elevating eyes and having hung out on the winch. Alternatively it is possible to prop up the engine a jack. Remove a rack of the right support of the engine and both arms of the right support (see. Section Removal and installation of the power unit).
  5. Remove the generator (see. The head of System of electric equipment of the engine) and a forward cover of a head of cylinders (see. Section Removal, check and installation of camshafts).
  1. Turn out auxiliary bolts of a head of cylinders.
  1. Establish the piston of the first cylinder in situation VMT as it is described in the Section Removal, check and installation of camshafts.
  1. Using an assembly opening of a starter, establish on a gear wreath of a flywheel a clamp to prevent a provorachivaniye of a cranked shaft. In qualities of alternative it is possible to block a counterbalance of a cranked shaft by means of the hammer handle after removal of the top section of the pallet of a case.
  1. Turn out a bolt of a cranked shaft.

Do not turn out fixing bolts since they will be used as support for a pulley stripper.


  1. Establish captures of a stripper (1) in a pro-point of a pulley (2) cranked shaft and remove a pulley.
  1. Remove from a forward cover of the block of cylinders of assembly of arms of intermediate pulleys of belts of a drive of auxiliary units (see. Section Replacement of belts of a drive of auxiliary units and intermediate rollers of belts).
  2. Accurately, trying not to damage a forward epiploon or the plug, remove the driving plug of the oil pump by means of long pincers or two screw-drivers.
  1. Turn out the bolts of A-C specified an illustrations and remove a forward cover of the block of cylinders.

Do not damage a forward part of laying of a head of cylinders. If it occurred, replace laying (see. Section Removal and installation, dismantling and assembly of a head of cylinders).

  1. Remove from the block of cylinders a sealing ring.
  1. Warm up pins (1) forward cover of the block of cylinders by means of the hair dryer (2) and remove pins pincers (3).
  1. Remove a forward epiploon, вытолкнув its screw-driver from within a forward cover outside.
  2. As it is described in the Section Removal, check and installation of camshafts, establish a regulator of phases of inlet valves in the provision of the maximum advancing, remove a natyazhitel of a chain of GRM and an asterisk of camshafts.

Thus to do marks in a chain it is not required.

  1. Remove a chain, it directing and the lever of a natyazhitel. Check a chain on existence of cracks and wear of rivets.
  2. Remove an asterisk of a cranked shaft.

Installation

Installation of asterisks, chains, it directing and the lever of a natyazhitel

1 — the Lilac or orange link
2 — the External circle
3 — Risk
4 — a camshaft Pin
5 — the Beaten-out label
6 — the Asterisk of a final shaft
7 — the Asterisk of an inlet shaft
8 — Natyazhitel of GRM chain
9 — Shponka of a cranked shaft
10 — the Dark blue link
11 — GRM Chain
12 — the Asterisk of a cranked shaft
13 — the Lever of a natyazhitel of a chain
14 — Directing to a chain


 PERFORMANCE ORDER

  1. Completely clear of the remains of old laying interfaced surfaces of all acting in film details.
  2. Establish asterisks, GRM chain, it directing and a natyazhitel so that various labels on them settled down according to an illustration above and were turned outside.

Establish the specified components in the following sequence: an asterisk of a cranked shaft and a chain, the lever of the natyazhitel, directing to a chain, asterisks of camshafts, a natyazhitel of a chain.

  1. Temporarily establish the driving plug of the oil pump, a pulley of a cranked shaft and a fixing bolt of a pulley that the cranked shaft could be turned.
  2. Turn a cranked shaft clockwise and establish a regulator of phases of inlet valves in the provision of the maximum delay (see. Section Removal, check and installation of camshafts).
  3. Once again turn a cranked shaft on some turns clockwise and make sure of coincidence of labels of GRM.
  4. Remove a pulley of a cranked shaft and the driving plug of the oil pump.
  5. By means of a suitable drift or a piece of a pipe of suitable diameter press a forward epiploon in a forward cover of the block of cylinders a stamping outside.
  1. Establish on the block of cylinders a new sealing ring (1) and by means of a screw-driver put hermetic on a joint between laying of a head of cylinders and the block of cylinders in two places (2).
  1. Put hermetic on a back part of a forward cover of the block of cylinders and on the top plane of a forward cover.
  1. As is shown in an illustration, establish a forward cover (1) as it is possible more densely to the block of cylinders (2), moving it parallel to a cranked shaft and surely leaving thus a small gap between a cover and laying (3) heads of cylinders. Then shift a cover on a diagonal to a joint of the block and a head of cylinders so that the cover was interfaced to laying of a head of cylinders.
  1. Temporarily fix a forward cover several bolts and press through it pins in the block of cylinders.

  1. Temporarily tighten bolts of fastening of a forward cover and auxiliary bolts of a head of cylinders. Then tighten the specified bolts with demanded efforts.
  1. Combine flat surfaces of the driving plug of the oil pump with its internal gear wheel and establish the plug, trying not to damage a forward epiploon.

If necessary turn an internal gear wheel of the pump a screw-driver.

  1. Establish assemblies of arms of intermediate rollers of belts of a drive of auxiliary units (see. Section Replacement of belts of a drive of auxiliary units and intermediate rollers of belts).
  2. Establish a pulley of a cranked shaft and tighten a bolt of its fastening.

Thus the cranked shaft should be blocked, as at pulley removal.

  1. Establish a forward cover of a head of cylinders (see. Section Removal, check and installation of camshafts).
  2. Establish an arm and a rack of the right support of the engine.
  3. Further installation is made in sequence, return to an order of dismantle of components.
  4. At least 30 minutes later after installation warm up the engine and check it on existence of leakages of impellent oil.
