Installation of base provision of camshafts

М111

Check

Verification of the base provision of camshafts of the engine of a series 111

PERFORMANCE ORDER

The illustrative material on verification of the base provision of camshafts of the engine of a series 111 is presented on an illustration which all references meeting in the text concern.
Uncover heads of cylinders (11).
Having turned a cranked shaft in the normal direction, bring the piston of the first cylinder into situation 20 ° after VMT, - the label 20 ° a measuring scale on a damper of krutilny fluctuations (95) should be combined with the index (And) on a cover of a drive of GRM, and cams of a drive of inlet (78) and final (77) valves of the first cylinder - to be developed by working ledges up at an angle.
Check freedom of passing of a blocking core (01) in openings of a cover of the bearing No. 1 or No. 6 and lock openings of an inlet or final camshaft.
In view of a tension of a gas-distributing chain the inlet camshaft should occupy situation between 20 and 30 degrees, and final - between 25 and 35 degrees after VMT.

Shift of landing of a chain on 1 tooth leads to 20-degree shift, - in case of need make the corresponding adjustment (see below).

At the correct base installation the emphasis on an asterisk (75) inlet camshafts should appear displaced towards "delay", i.e. to be shifted in flange sample in the direction of rotation of a camshaft (shooter).
Дейтсвуя as it should be, the return to a dismantle order, establish into place acting in film components.

Installation

Installation of base provision of camshafts of the engine of a series 111

PERFORMANCE ORDER

The illustrative material on adjustment of base provision of camshafts of the engine of a series 111 is presented on an illustration which all references meeting in the text concern.
Check base installation of camshafts (see above).
Remove a forward cover of a head of cylinders (see. Section Removal and installation of covers of a drive of GRM).
Having turned a cranked shaft in the normal direction, bring the piston of the first cylinder into situation 30 ° after VMT, - in this position of the engine camshafts can be turned without risk of collision of valves with pistons.
Remove a natyazhitel of a chain (14) (see. Section Removal and installation of components of a drive of GRM).
Remove an asterisk (78) final camshafts.
Having pulled up, remove a gas-distributing chain (73) from an asterisk (75) inlet camshafts.
Develop camshafts in base situation and fix from blocking the pins (01) passed through openings in covers of No. No. 1 and 6 bearings.
Having delayed a chain up, return the piston of the first cylinder to situation 20 ° after VMT.
Throw with a chain (73) an asterisk (75) inlet camshafts, previously having made sure of correctness of situation of the last.
Previously having filled in a chain, establish into place an asterisk (78) final shaft.
Establish into place a natyazhitel of a chain (14) (see. Section Removal and installation of components of a drive of GRM).
Take blocking cores (01).
Make sure of correctness of base installations (see above).

M112/113

Check and installation

Installation of base provision of camshafts of engines of series 112 and 113

PERFORMANCE ORDER

The illustrative material on adjustment of base provision of camshafts of engines of series 112 and 113 is presented on an illustration which all references meeting in the text concern.
Remove covers of heads of cylinders.
Check correctness of base provision of camshafts, - in case of need develop the engine in situation 40 ° after VMT of the piston of the first cylinder.
Remove a natyazhitel of a chain (see. Section Removal and installation of components of a drive of GRM).
Remove the Hall sensor.
Having lifted a chain, remove an asterisk at first right, then the left camshaft.
By means of a rozhkovy key develop the left camshaft in base situation, - developed to the diametrical plane of the engine grooves (6) should be combined with the line of a joint of covers with heads, - and fix it a blocking plate (2), having planted the last aflush with the left head and having filled in a groove (6) camshafts.

In position of the piston of the first cylinder 40 ° after VMT the camshaft can turn without risk of collision of pistons with valves.

Operating in a similar manner, expose the right camshaft.
Filling in a chain, establish to the place of an asterisk of camshafts (at first left, then right).
Establish the Hall sensor.
Establish a natyazhitel of a chain (see. Section Removal and installation of components of a drive of GRM).
Make sure of correctness of combination of adjusting labels, then establish to the place of a cover of heads of cylinders.
