Works order

Priveditekolenval by means of a fixing bolt of a damper of krutilny fluctuations in the direction of rotation of the engine to VMT mark цил. 1.

Remove an inlet collector and a cover of a head of the block of cylinders.

Remove the thermostat case.

Remove a natyazhitel of a chain of a drive of GRM.

Unscrew a cover of cam-shafts.

Fig. 2.72 . Places of drawing of labels

Before removal mark the direction of a course of roller chains (e.g. to put with paint to the shooter specifying the direction of a course of a chain) (fig. 2.72) .

NOTE Do not put a notch with a center punch or similar the tool.

At first remove the coupling of shift of a final cam-shaft.

To hold a cam-shaft in the fixed situation follows only by means of a vilochny key 32. At an inhaling or untwisting of phase shifters the ruler for cam-shafts of T10068 A should not be enclosed in flutes.

Remove the coupling of shift of a cam-shaft together with a roller chain of a drive of GRM from an inlet shaft.

Put a chain of a drive of GRM aside, having put it sideways.

Fig. 2.73 . Bolts of fastening of the case of a regulator

Unscrew the regulator case from a head of the block of cylinders (fig. 2.73) .

Accurately uncover the distributive mechanism manzhetny consolidations of cam-shafts.

Inlet cam-shaft

Remove at first covers of bearings 1 and 13.

Then remove covers of bearings 3 and 11.

Uncover the bearing 7.

Components of a zolotnikovy box: 1–electromagnetic valve 2; 2–shtekerny connection of the sensor of frequency of rotation of a target shaft of KP; 3–the pressure sensor for hydrosystem 2 in AKP G194; 4–the pressure sensor for hydrosystem 1 in AKP G193; 5–electromagnetic valve 4; 6–sensor of frequency of rotation of a target shaft of KP; 7–sensor of temperature of oil of a transmission; 8–electromagnetic valve 6; 9–electromagnetic valve 3; 10-electromagnetic valve 5; 11-electromagnetic valve 10; 12-electromagnetic valve 1

Weaken and remove covers of bearings 5 and 9, alternating cross-wise (fig. 3.74) .

Final cam-shaft

Remove at first covers of bearings 2 and 14.

Then remove covers of bearings 4 and 12.

Uncover the bearing 8.

Fig. 2.74 . Inlet and final cam-shafts

Weaken and remove covers of support 6 and 10, alternating cross-wise (fig. 2.74) .

Accurately take cam-shafts and put them on a pure lining.

Take roller levers together with support and postpone them for a pure lining.

It is forbidden to interchange the position of roller levers and basic elements.
