Removal, check of a condition and installation газораспределительного a belt and cogwheels of drive ГРМ
Removal
|
|
Exact observance of phases газораспределения is very important, but for engines DOHC important extremely. Incorrect installation of phases can seriously damage the engine. Be accurate at installation of a belt of drive ГРМ and before the first start after repair once again check up coincidence of labels.
|
Assemblage of drive ГРМ
|
|
1. Disconnect a negative wire from the battery.
|
|
If the stereosystem established on the car is equipped by a security code before to disconnect the battery make sure that have a correct combination for audiosystem input in action! |
2. Remove protection картера.
3. Merge cooling liquid from a radiator and the engine block (see the Head of System of cooling of the engine, salon and air conditioning heating).
4. Remove a radiator (see the 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 приводной a belt with муфтой and a pulley of a cranked shaft.
8. Without disconnecting hydraulic tubes, remove pump GUR, take him aside and tie up it so that it did not disturb.
9. Having turned away a bolt, then having uncovered, remove an intermediate roller приводного a belt (address to an illustration above).
10. Remove the right cover (right №3) a belt of drive ГРМ.
11. Remove the left cover (left №3) a belt of drive ГРМ. Be cautious at a detachment of conducting of the gauge of position of a camshaft (CMP).
12. Remove the following cover of belt ГРМ (a cover №2).
13. Without disconnecting tubes К/В, remove compressor K/V, 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 the belt of drive ГРМ has to be established 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. Ослабьте, but do not turn out a bolt of fastening of a pulley of a cranked shaft. For deduction of a cranked shaft from проворачивания the special tool is required.
17. Establish the piston of the cylinder №1 in ВМТ a compression step.
- Turn a pulley of a cranked shaft so that its risk It was combined with a label to a cover №1 belts ГРМ.
- Check up coincidence of labels on cogwheels of camshafts with labels on back covers of belt ГРМ. If labels do not coincide, the piston of the cylinder №1 in ВМТ a compression step is not established. Turn a cranked shaft precisely on one turn before following combination of a label of a pulley with a label 0 on a cover №1 belts of drive ГРМ.
- Turn away a bolt of a pulley of a cranked shaft, trying not to bring down a label. A pulley of a cranked shaft do not rotate.
18. Having turned away two bolts, remove натяжитель a belt of drive ГРМ and пыльник. If it is replaced only натяжитель a belt, 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 ослабьте a belt tension between cogwheels of camshafts, having put on накидной a key a bolt of fastening of an asterisk of the left camshaft and slightly having turned it clockwise.
|
|
20. For removal of cogwheels of camshafts вильчатым the tool fix a cogwheel from проворачивания and turn away the central bolt (address to an accompanying illustration). Try not to turn cogwheels. |
21. Remove the generator.
22. Remove натяжитель приводного a 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 approaching for it. Do not turn a cranked shaft not to bring down installation ВМТ.
24. Remove the bottom cover of a belt of drive ГРМ (a cover №1).
25. Remove directing washer and the cover prorate.
26. Remove from the engine a belt of drive ГРМ. If the belt has to be established back, and adjusting labels on it were erased, put new concerning a dot label on a cogwheel of a cranked shaft.
27. If it is necessary, remove intermediate rollers and check up smoothness of their rotation.
28. If it is necessary to remove a cogwheel of a cranked shaft, pull together with its suitable stripper. Try not to shift a cranked shaft with ВМТ. |
|
Check
|
|
1. Check up a condition of a belt of drive ГРМ. Do not bend it at an acute angle and do not turn inside out. Do not suppose hit on a belt of oil, water, antifreeze or solvents. If there are damages of teeths of a belt, check up, whether camshafts are blocked. If there is an appreciable deterioration or cracks on a back surface of a belt, check up absence of damages of a surface of rollers and a pulley of the water pump. At revealing of unilateral deterioration of a belt check up parallelism of pulleys and their axes, directing washer. If there is an appreciable deterioration of teeths of a belt, damages of covers of a belt or teeths of cogwheels are possible. For отворачивания bolts of fastening of cogwheels of camshafts do not use a tension of a belt of drive ГРМ.
|
|
2. Check up a condition of intermediate rollers. Check up integrity of consolidations of their bearings. If it is necessary, rollers replace. Check up absence of a leak натяжителя. Try to push a rod – it should not move. If the rod manages to be pushed, replace натяжитель. Measure a rod ledge – it should be equal 10.5 – 11.5 mm (address to an accompanying illustration). |
3. Check up absence of a leak of the water pump. The pump should rotate smoothly, without люфтов. |
|
Installation
|
|
1. If acted in film, establish a cogwheel of a cranked shaft, having combined шпонку not it 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 hermetic Loctite 242 or similar. Tighten bolts with effort of 35 Nanometers. Check up smoothness of rotation of rollers.
3. Temporarily establish a belt of drive ГРМ. Carefully clear cogwheels and rollers of oil and water, wipe their 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.

The effort of an order 981-987 N.Sovmestite of a rod and case aperture натяжителя For this purpose is required and insert a pin in diameter of 1.27 mm to fix a rod. Release a press and put on пыльник. Establish натяжитель on the engine and tighten alternately bolts of its fastening by the moment of 26 Nanometers. Having established натяжитель, take a pin flat-nose pliers.
14. Check up labels газораспределения. 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 газораспределения on cogwheels and a pulley.
15. If labels газораспределения coincide, tighten a bolt of fastening of a pulley the moment of 245 Nanometers. For deduction of a pulley from проворачивания it is required вильчатый the tool.
16. Establish a fan arm. Establish bolts of fastening of an arm on the places. Bolts are tightened as follows:
- Bolts with heads of 12 mm tighten with effort of 16 Nanometers.
- Bolts with heads of 14 mm tighten the moment of 32 Nanometers.
17. Establish compressor K/V (at a corresponding complete set).
18. Establish a cover №2 belts of drive ГРМ and tighten two bolts of its fastening with effort 16Нм.

20. Establish the left cover of belt ГРМ:
- Establish a tube маслоохладителя, having fixed its nut with a bolt.
- Spend gauge CMP conducting through an aperture in a cover.
- Establish a cover of a belt of drive ГРМ, having combined it with a fan arm.
- Tighten a bolt and a nut with effort of 7.5 Nanometers.
- Establish a sealant of conducting of the gauge in a cover, attach a socket and attach it to an arm.
- Fix engine conducting.
