Repair and car operation

Removal, check of a condition and installation of a gas-distributing belt and cogwheels of a drive of GRM

Removal

Exact observance of phases of a gazoraspredeleniye is very important, but for DOHC engines important extremely. Incorrect installation of phases can seriously damage the engine. Be accurate at installation of a belt of a drive of GRM and before the first start after repair once again check coincidence of labels.

Assembly of a drive of GRM

PERFORMANCE ORDER

1. Disconnect a negative wire from the battery.

If the stereosystem established on the car is equipped with a security code before disconnecting the battery make sure that have the correct combination for audiosystem input in action!

2. Remove protection of a case.
3. Merge cooling liquid from a radiator and the engine block (see. Head of System of cooling of the engine, salon and air conditioning heating).
4. Remove a radiator (see. Head of System of cooling of the engine, salon and air conditioning heating).
5. Uncover throttle cases.
6. Remove an inlet air line.
7. Remove a driving belt with the coupling and a pulley of a cranked shaft.
8. Without disconnecting hydraulic tubes, remove the pump GUR, take him aside and tie up it so that it did not disturb.
9. Having unscrewed a bolt, then having uncovered, remove an intermediate roller of a driving belt (address to an illustration above).
10. Remove the right cover (right No. 3) a belt of a drive of GRM.
11. Remove the left cover (left No. 3) a belt of a drive of GRM. Be careful at a detachment of conducting of the sensor of provision of a camshaft (CMP).
12. Remove the following cover of a GRM belt (cover No. 2).
13. Without disconnecting tubes To/in, remove the To/in compressor, take him aside and tie up there that did not disturb.
14. Remove a fan arm. For its fastening bolts of the different size are used – combine them so that not to mix at installation.

15. If it is necessary to establish a belt of a drive of GRM back, find on it three adjusting labels, rotating a cranked shaft clockwise. Find labels on cogwheels of a cranked shaft and camshafts. If labels on a belt were erased, put new to facilitate installation (address to an accompanying illustration).

16. Weaken, but do not turn out a bolt of fastening of a pulley of a cranked shaft. Deduction of a cranked shaft from a provorachivaniye will need the special tool.
17. Establish the cylinder No. 1 piston in VMT of a step of compression.

Turn a pulley of a cranked shaft so that its risk It was combined with a label to a GRM belt cover No. 1.
Check coincidence of labels on cogwheels of camshafts with labels on back covers of a GRM belt. If labels do not coincide, the cylinder No. 1 piston in VMT of a step of compression is not established. Turn a cranked shaft precisely on one turn before the following combination of a label of a pulley with a label 0 on a cover of No. of 1 belt of a drive of GRM.
Unscrew a bolt of a pulley of a cranked shaft, trying not to bring down labels. A pulley of a cranked shaft do not rotate.

18. Having unscrewed two bolts, remove a natyazhitel of a belt of a drive of GRM and a boot. If the natyazhitel of a belt is replaced only, fix a belt on a pulley a wire. Put labels on a belt and a cogwheel of the right camshaft.
19. Remove a belt from cogwheels of camshafts. For this purpose weaken a belt tension between cogwheels of camshafts, having put on a cap key a bolt of fastening of an asterisk of the left camshaft and having slightly turned it clockwise.

20. For removal of cogwheels of camshafts by the bifurcate tool fix a cogwheel from a provorachivaniye and unscrew the central bolt (address to an accompanying illustration). Try not to turn cogwheels.

21. Remove the generator.
22. Remove a natyazhitel of a driving belt.
23. For removal of a pulley of a cranked shaft the central bolt should be already turned out. Pull together a pulley from a sock of a cranked shaft with a stripper suitable for this purpose. Do not turn a cranked shaft not to bring down VMT installation.
24. Remove the bottom cover of a belt of a drive GRM (cover No. 1).
25. Remove directing washer and a cover pro-rate.
26. Remove from the engine a belt of a drive of GRM. If it is necessary to establish a belt back, and adjusting labels on it were erased, put new rather dot label on a cogwheel of a cranked shaft.
27. If it is necessary, remove intermediate rollers and check smoothness of their rotation.
28. If it is necessary to remove a cogwheel of a cranked shaft, pull together it with a suitable stripper. Try not to shift a cranked shaft with VMT.

Check

PERFORMANCE ORDER

1. Check a condition of a belt of a drive of GRM. Do not bend it at an acute angle and do not turn inside out. Do not allow hit on a belt of oil, water, antifreeze or solvents. If there are damages of teeths of a belt, check, whether camshafts are blocked. If there is an appreciable wear or cracks on a back surface of a belt, check absence of damages of a surface of rollers and a pulley of the water pump. At detection of unilateral wear of a belt check parallelism of pulleys and their axes, directing washer. If there is an appreciable wear of teeths of a belt, damages of covers of a belt or teeths of cogwheels are possible. For an otvorachivaniye of bolts of fastening of cogwheels of camshafts do not use a tension of a belt of a drive of GRM.

2. Check a condition of intermediate rollers. Check integrity of consolidations of their bearings. If it is necessary, rollers replace. Check lack of a leak of a natyazhitel. Try to push a rod – it should not move. If the rod manages to be pushed, replace a natyazhitel. Measure a rod ledge – it should be equal 10.5 – 11.5 mm (address to an accompanying illustration).

3. Check lack of a leak of the water pump. The pump should rotate smoothly, without люфтов.

Installation

PERFORMANCE ORDER

1. If acted in film, establish a cogwheel of a cranked shaft, having combined a shponka it is not mute with a flute. Probably, it is required accurately напрессовать a cogwheel on a shaft by means of a suitable piece of a pipe.
2. Establish intermediate rollers. Put on a carving of bolts some drops of fixing Loctite 242 hermetic or similar. Tighten bolts with effort of 35 Nanometers. Check smoothness of rotation of rollers.
3. Temporarily establish a belt of a drive of GRM. Carefully clear cogwheels and rollers of oil and water, wipe them pure dry rags. Solvents do not use. Combine an adjusting label of a belt with a label of a cogwheel of a cranked shaft. Put on a belt a cogwheel of a cranked shaft and pulleys of parasitic rollers.

9. Establish the generator.
10. Check the provision of a pulley of a cranked shaft. Risk on a pulley it should be combined with a label 0 on a cover of a belt of a drive of GRM.
11. Establish cogwheels of camshafts. Put on cogwheels, having combined their openings with pins of camshafts. Holding cogwheels from a provorachivaniye the bifurcate tool, tighten bolts of their fastening with effort of 108 Nanometers. Carefully clear cogwheels and dry wipe them pure rags. Solvents do not use.
12. Establish a belt on cogwheels of camshafts:

Turn a cogwheel of the left camshaft before combination of its label of a gazoraspredeleniye with an adjusting label on a belt of a drive of GRM. Put on a belt a cogwheel.

Turn a cogwheel of the right camshaft before combination of an adjusting label of a belt with a label of a gazoraspredeleniye of a cogwheel. Put on a belt a cogwheel.

13. By means of a press press a rod of a natyazhitel. For this purpose about 981-987 N.Sovmestite's effort of an opening of a rod and the case of a natyazhitel is required and insert a pin in diameter of 1.27 mm to fix a rod. Release a press and put on a boot. Establish a natyazhitel on the engine and tighten alternately bolts of its fastening the moment of 26 Nanometers. Having established to a natyazhitel, take a pin flat-nose pliers.
14. Check gazoraspredeleniye labels. Temporarily establish a bolt of fastening of a pulley of a cranked shaft. Slowly turn a cranked shaft clockwise on two complete revolutions. Verify coincidence of labels of a gazoraspredeleniye on cogwheels and a pulley.
15. If labels of a gazoraspredeleniye coincide, tighten a bolt of fastening of a pulley the moment of 245 Nanometers. Pulley deduction from a provorachivaniye will need the bifurcate tool.
