  1. Slowly turn a camshaft of final valves for a bolt of fastening of an asterisk clockwise before complete compression of a natyazhitel of a chain then establish the adaptation No. 11 3 340 in a natyazhitel of a chain (see an illustration).

At removal of one or both asterisks without preliminary blocking of a natyazhitel of a chain probably vyskalzyvany outside of the piston of the natyazhitel which installation into place is very labor-consuming operation.


  1. Weaken a bolt (1) on distributive to a shaft of inlet valves, and then completely turn out a bolt (2) on distributive to a shaft of final valves.
  1. Shift forward an asterisk of a cam-shaft of final valves, lift over it a chain (1) and remove an asterisk (2) in the arrow direction.
  1. Turn out a bolt of fastening of an asterisk of a camshaft of inlet valves and remove an asterisk.
  1. Twist a basic finger (1) level of a natyazhitel of a chain and a basic finger (2) directing chains.

At installation replace removal fingers. Extend up a level of a natyazhitel and GRM directing to a chain. Remove No. No. 11 6 321 adaptations, 11 6 322.

In order to avoid damage of valves at the subsequent installation of camshafts any of pistons should not be in situation VMT.

  1. Remove the adaptation for engine fixing in situation VMT (No. 11 2 300). Delay GRM chain up and hold her in the tense condition so that it was possible to turn the engine. Turn the engine for a damper of krutilny fluctuations by means of the special adaptation No. 11 6 480 approximately on a corner 45 ° counter-clockwise.
  2. Evenly, in stages on a half of turn, turn out bolts of fastening of covers of bearings of camshafts in sequence from edges to the middle. Remove covers of bearings and put them aside, having in an order providing possibility of the subsequent installation of covers of bearings on former places.
  3. Remove at first a camshaft of inlet valves, and then – a shaft of final valves.
  1. Remove all yokes (1) and hydrojacks of klapanny gaps and arrange them in an order providing possibility of the subsequent installation on former places.
  1. Turn out bolts.
  1. Turn out bolts of fastening of a head of the block of cylinders in return sequence.

The reuse of bolts of fastening of a head of cylinders is not admissible.

Do not damage a glow plug, acting it is necessary the plane of a head of cylinders.

  1. If necessary remove glow plugs.
  1. Remove laying (1) head of cylinders, pay attention to quantity of openings (2) in laying. Clear all deaf carving openings (3) of the oil, cooling liquid and dirt. Clear an interfaced surface (4).

Installation

 PERFORMANCE ORDER

  1. If on the block of cylinders the works causing change of a ledge of the bottom of pistons were not carried out, it is necessary to use new laying of a head of the block with the same marking (1 see an illustration) thickness, as on old laying. Otherwise it is necessary to define anew repair thickness of sealing laying, having measured for this purpose a ledge of the bottom of all pistons concerning the plane of the block of cylinders. At a ledge from 0.92 to 1.03 mm use laying with 2 openings, and at a ledge more than 1.03 mm - with 3 openings.
  2. Check aligning plugs in the block of cylinders on absence of damages and correctness of installation; if necessary replace plugs.
  3. Establish new laying of a head of cylinders and fix a head on the block of cylinders new bolts, having tightened them in the specified sequence (see an illustration).
  4. Tighten bolts (see an illustration).
  5. Grease with impellent oil of a bed and a cover of bearings of camshafts. Establish all yokes and hydrojacks on their former places.
  6. Establish camshafts.

On inlet «E» label, and on the final – «A» is put to a shaft; covers of bearings have the same alphabetic references, and also the digital designations indicating an arrangement of a cover, considering from release. Establish covers of bearings of camshafts and tighten their fixing bolts.


  1. Turn camshafts for shestigrannik so that tops of cams of inlet and final valves of the 1st cylinder specified at each other.

  8. Remove from a final camshaft the adaptation No. 11 6 321.
  9. Delay the adaptation No. 11 2 300 back so to release a flywheel (see an illustration).
  10. Turn the engine by means of the adaptation No. 11 6 480 twice in the rotation direction before position of the piston of the first cylinder directly ahead of VMT of the end of a step of compression.
  11. Turn the engine in the rotation direction to situation VMT so that the adaptation No. 11 2 300 (a fixing pin) was fixed with heard click.

The engine provorachivaniye in the opposite direction is not allowed.

  1. Block a cranked shaft in the situation relevant to VMT of the piston of the first cylinder by means of the adaptation No. 11 2 300 (see an illustration).
  2. Establish the adaptation No. 11 6 321 on a camshaft of inlet valves.

The adaptation No. 11 6 321 should adjoin without a gap to a head of the block of cylinders.

  1. Establish the adaptation No. 11 6 321 on a camshaft of final valves so that it without a gap adjoined to a head of cylinders.
  2. Remove the adaptation No. 11 6 321 from a camshaft of final valves. Remove adaptations No. 11 6 322 and No. 11 2 300.
