Removal, check of a condition and installation газораспределительного a belt and cogwheels of drive ГРМ
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.
2. Remove protection картера.
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!
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.
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.
||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).
17. Establish the piston of the cylinder №1 in ВМТ a compression step.
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.
- 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.
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.
21. Remove the generator.
||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.
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.
|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.
3. Check up absence of a leak of the water pump. The pump should rotate smoothly, without люфтов.
||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).
|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.
4. Establish the prorate of a cover of belt ГРМ.
5. Establish directing washer the convex party outside.
6. Establish a cover of a belt of drive ГРМ and fix its four bolts.
7. Establish a pulley of a cranked shaft. Combine шпонку with a cut and establish a pulley. For this purpose, probably, it is necessary напрессовать a pulley by means of a piece of a suitable pipe.
8. Establish натяжитель приводного a belt (not belt ГРМ). A bolt in length of 106 mm and nuts tighten with effort of 16 Nanometers.
9. Establish the generator.
10. Check up position 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 drive ГРМ.
11. Establish cogwheels of camshafts. Put on cogwheels, having combined their apertures with pins of camshafts. Keeping cogwheels from проворачивания вильчатым the tool, tighten bolts of their fastening with effort of 108 Nanometers. Carefully clear cogwheels and dry wipe their 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 газораспределения with an adjusting label on a belt of drive ГРМ. Put on a belt a cogwheel.
- Turn a cogwheel of the left camshaft counter-clockwise that there was a belt tension on a shoulder between cogwheels of the left camshaft and a cranked shaft.
- Turn a cogwheel of the right camshaft before combination of an adjusting label of a belt with a label газораспределения a cogwheel. Put on a belt a cogwheel.
13. By means of a press press a rod натяжителя. 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.
