Removal

PERFORMANCE ORDER
1. Disconnect the battery from weight.
2. Remove the lower guard of the engine.
3. Remove a casing and the fan.
4. Merge liquid and remove a radiator.
5. Take off belts of the generator and pump of the hydraulic booster.
6. Disconnect from wire candles.
7. Lift a car front, block back wheels.
8. On engines of 3,0 l turn out hairpins from a branch pipe of cooling liquid.
9. On engines of 3,4 l remove the pump of the hydraulic booster and take aside.
10. Remove the conditioner compressor (see subsection 4.13).
11. Turn out candles.
12. Remove the top cover of a belt and laying. On engines of 3,4 l remove a nave of the fan and an arm.
13. Install the piston of the 1st cylinder in compression step VMT.
14. Check existence of adjusting tags on a gear belt. If necessary put tags.
15. Be convinced of combination of tags on a cam-shaft gear wheel (at the left – tags on the engine of 3,0 l, on the right – tags on the engine of 3,4 l).
16. Remove a natyazhitel and a cover (at the left – a natyazhitel of a gear belt on the engine of 3,0 l, on the right – a natyazhitel of a gear belt on the engine of 3,4 l, shooters specified bolts of a natyazhitel).
17. If the gear belt does not change, then designate tags its situation on an asterisk of a cam-shaft of final valves.
18. Take off a gear belt from cam-shaft asterisks.
19. Examine asterisks of cam-shafts, if necessary replace. For this purpose uncover (covers) and holding a cam-shaft a key for lysk, turn off a bolt and remove an asterisk.
20. Shoot a video of a natyazhitel N 2.
21. Turn off a crankshaft bolt, having recorded (shooter) a flywheel wreath (or holding a hydrotransformer disk bolt).
22. Double-check combination of tags of VMT on a pulley of the crankshaft and a motionless scale.
23. Remove a pulley by hand or by means of two screw-drivers, working as levers.
24. Remove the lower cover of a belt and laying. On engines of 3,4 l previously remove a fan arm.
25. Take off a belt from the leading asterisk.
26. Shoot a video of a natyazhitel of N1.
27. Check existence of a tag on a belt opposite to deepening in the leading asterisk, if necessary put a new tag (if the belt does not change).
28. If necessary remove the leading asterisk by hand or by means of two screw-drivers, working as levers.

Check

PERFORMANCE ORDER
1. Check a condition of a belt. In the presence of cracks, anguishes, cuts, the cut-off teeths or if operation term expired, replace a belt.
2. Check oil potek on a natyazhitel. The epiploon of a natyazhitel is serviceable if only weak traces from oil from a plunger are observed.
3. Check the plunger course, having rested it against a motionless surface. If the plunger is displaced, then a natyazhitel replace.
4. Check a vystupaniye of a plunger of a natyazhitel. If the vystupaniye differs from normal, then a natyazhitel replace.
5. Check freedom of rotation of rollers of a natyazhitel.

Installation

PERFORMANCE ORDER
1. Clear a forward part of the engine.
2. On engines of 3,0 l combine tags on a wreath of the leading asterisk and on the case of the oil pump. Establish the leading asterisk so that a flange part was turned towards the engine.
3. On engines of 3,4 l do not damage an insert of the sensor of rotation of the crankshaft on the leading asterisk. Check combination of the specified tags.
4. Establish a roller of a natyazhitel of a N 1 belt, having greased 2–3 strings of a carving of a bolt of a natyazhitel with frictional structure. Tighten a bolt with the set moment.
5. Put on a gear belt, having got it on the leading asterisk. If the taken-off belt is established, then combine tags on a belt, asterisks and covers, put at removal.
6. Dress the directing cup on the crankshaft, having turned it a convex surface towards the engine.
7. Dress a pulley of the crankshaft and tighten a bolt with the set moment, holding the crankshaft (shooter).
8. Establish the top roller of a natyazhitel. Tighten a bolt and check freedom of rotation of a roller.
9. Establish an asterisk of the left cam-shaft by a flange part outside, having combined an opening in an asterisk with a cam-shaft pin.
10. Tighten an asterisk bolt with the set moment.
11. Again check tags and be convinced that the crankshaft was not turned rather starting position (at the left – combination of tags on the engine of 3,0 l, on the right – combination of tags on the engine of 3,4 l). If the taken-off belt puts on, then establish it on the tags put at removal. If tags do not coincide, then move a belt on the leading asterisk. The tag on an asterisk of the left cam-shaft has to be turned up and coincide with a tag on a back cover of a belt.
12. The opening under a pin in an asterisk of the right cam-shaft has to be turned up (for 12 hours). If necessary uncover a head of cylinders (if did not act) and turn a cam-shaft before combination of tags on a cam-shaft and on a back cover.
13. Turn the left cam-shaft to an hourly arrow approximately on one step between teeths. If the taken-off belt puts on, then combine an adjusting tag with a tag on a cam-shaft asterisk. Put on a belt on an asterisk and turn a cam-shaft against an hour hand, having returned it to a starting position. The belt has to have a small tension now.
14. Having combined an opening with a pin, establish an asterisk of the right cam-shaft so that a flange part was turned inside.
15. Tighten an asterisk bolt, keeping the provision of tags.
16. Put on a belt on an asterisk, having combined tags (if the taken-off belt is established).
17. Squeeze in a vice a natyazhitel and drown a plunger. Record a plunger, having inserted a drill with a diameter of 1,2 mm into cross through openings.
18. Establish a natyazhitel and tighten bolts.
19. Turn the crankshaft on 2 turns and check combination of tags. If tags are not combined, then repeat all actions for installation of a belt. It is forbidden to start the engine until is full confidence in the correct installation of a belt.
20. Establish other details upside-down.
