REMOVAL

 PERFORMANCE ORDER

 Does not follow without need to remove epiploons of camshafts. At removal of epiploons try not to injure necks of shaft!

1. Take off a V-shaped belt (see the Head Routine maintenance).
2. Remove a pulley of a cranked shaft (see the Section Removal and installation of a pulley of a cranked shaft).
3. Uncover the GRM driving belt (see the Section Removal and installation of forward covers of the GRM drive).
4. Remove assembly of a GRM belt (see the Section Removal and installation of a belt of the GRM drive, check of a condition of components).
5. Remove a camshaft cogwheel (see the Section Removal, check of a state and installation of cogwheels of camshafts).
6. Remove a cogwheel of a cranked shaft (see the Section Removal and installation of a cogwheel of a cranked shaft).
Remove the left section of a back cover of the GRM drive.

 Attention: Try not to damage and not to lose lose a rubber sealant!

7. Remove the right section of a back cover of the GRM drive.

 Try not to damage and not to lose lose a rubber sealant!

8. Remove an arm of a natyazhitel of a gas-distributing belt.

9. On the left semi-block remove a support of the sensor of provision of a camshaft (CMP) and the directing tube of the probe of measurement of level of motive oil.
10. Remove assembly of yokes (see the Section Removal, check of a state and installation of elements of the drive of valves).

11. Turn out consistently bolts (1) and (2) fastenings of a cover of a camshaft.

12. Working in ascending order of serial numbers, evenly weaken the next eight bolts (with [3] on [10]) fastenings of a cover of a camshaft.

13. By means of a special key like TORX PLUS (ST 499497000) turn out in ascending order of serial numbers the remained six fixing bolts (with [11] on [16]).

14. Accurately uncover a camshaft.

15. Take a camshaft.
16. Remove an epiploon.
17. Remove the cap established from the back party of a shaft.

CHECK

 PERFORMANCE ORDER

1. Having laid a shaft special prisms of a V-shaped form, by means of the dial measuring instrument of plunger type determine the size of its radial beating. Estimate degree of wear of bearing necks. In case of need make the corresponding recovery repair, or replace a shaft.


2. Measure outer diameters of necks of a camshaft and internal diameters of beds of the corresponding bearings in a head of cylinders. Determine by way of subtraction of result of the first measurement from result of the second the size of working gaps of bearings. Compare results of calculations to requirements of Specifications, in case of need replace a shaft, or a head.

3. Estimate a condition of working surfaces of cams of a shaft. Minor defects can be eliminated by means of a grinding stone. Measure geometrical parameters of cams. Compare results of measurements to requirements of Specifications, in case of need replace a shaft.

4. Determine the size of an axial side play of camshafts by the dial measuring instrument of plunger type. Compare results of measurements to requirements of Specifications, in case of need replace a shaft support.

INSTALLATION

 PERFORMANCE ORDER

1. Apply a layer of motive oil on necks of a camshaft and establish it.
2. Apply Three Bond 1280B P/N K0877YA018 sealant on perimeter of the interfaced camshaft cover surface. The pillow of sealant has to have the section of 3 mm in the diameter (A) and is imposed on edge (B) of a contact surface of a cover (C).

3. Temporarily tighten as increase in serial numbers bolts with (7) on (10).
4. Establish assembly of yokes (see the Section Removal, check of a state and installation of elements of the drive of valves).
5. Working in strictly certain order, tighten with the demanded effort bolts of fastening of assembly of yokes (see the Section Removal, check of a state and installation of elements of the drive of valves).
6. By means of a special key like TORX PLUS (ST 499497000), moving in ascending order of serial numbers, tighten with the demanded effort (18 Nanometers) bolts with (11) on (16).
7. Working in ascending order of serial numbers, tighten with the demanded effort (10 Nanometers) bolts with (3) on (9).
8. Working in ascending order of serial numbers, tighten with the demanded effort (10 Nanometers) bolts (1) and (2).

9. Previously having greased sealing sponges, by means of a special mandrel (ST 499597000) and a pro-rate of ST 499587500 put on a camshaft pin the NEW epiploon (And) (see sopr. illustration).

10. By means of the adaptation for installation of epiploons of ST 499587700 put into place a cap.
11. Make adjustment of valvate gaps (see the Section Check and adjustment of valvate gaps).
12. Establish a cover of a head of cylinders and connect a hose of ventilation of a case (PCV).
13. Further installation is made as it should be, the return to an order of dismantle of components
