Repair and car operation

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

Removal

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. Prop up back wheels protivootkatny boots and strongly cock the parking brake. 3. Weaken nuts of fastening of forward wheels, then поддомкратьте a front of the car and establish it on props (see. Head Routine maintenance). 4. Remove forward wheels and protection of a case of the engine. 5. Prop up a jack the power unit (for the purpose of distribution of loading lay between a head of a jack and the pallet of a case of the engine wooden whetstone). 6. Remove an arm of the top support of the engine (see. Check of a condition and replacement of support of a suspension bracket of the power unit). 7. Turn out spark plugs and remove driving belts (see. Routine maintenance). 8. To Otboltita the steering pump also shift it aside, without disuniting hydraulic lines (see. Head Suspension bracket and steering). 9. Remove the actuation mechanism of a control system in the speed (темпостата) (see. Head Onboard electric equipment). 10. Bring the piston of the first cylinder into the provision VMT of the end of a step of compression (see. Adjustment of seats). The cranked shaft should be turned only in the normal direction (counter-clockwise) – default of this requirement will lead to violation of adjustments of a gas-distributing belt. 11. Uncover heads of cylinders (see. The equipment and governing bodies in salon). 12a. Remove the central cover of a gas-distributing belt. 12b. Remove the bottom cover of a gas-distributing belt. (see accompanying illustrations). The top cover is incorporated with a head cover. 13. On a half of turn weaken a bolt of a natyazhitel of a belt (see an accompanying illustration). Having wrung out a natyazhitel, weaken a belt, then again tighten a bolt. 14. By means of a chain or tape key block a pulley of a cranked shaft from a provorachivaniye, then a face key weaken a bolt of fastening of a pulley (see an accompanying illustration). 15. Remove a pulley from a pin of a cranked shaft. 16. If the old belt is in good repair and will be established into place, mark with chalk or white paint the original direction of its rotation and situation concerning cogwheels of shaft (see an accompanying illustration). 17. Weaken a bolt of fastening of a natyazhitel. Having wrung out a natyazhitel, weaken a belt, then again tighten a bolt. Throw off a belt from cogwheels and remove it from the engine. If removal of a belt is made for the purpose of performance of replacement of an epiploon of a cranked shaft, throw off from a pin of the last a cogwheel and internal directing a belt (see. Safety systems). 18. If there is a need for removal of camshafts, or replacement of their epiploons, pass a big screw-driver through an opening in a cogwheel of the corresponding shaft for the purpose of blocking it from a provorachivaniye, then a face key weaken a fixing bolt and remove a wheel. Take from a camshaft pin a segment shponka. The wheel of the second shaft acts in film in a similar manner.

Check

Try not to allow provorachivaniye of cogwheels cranked or camshafts at the removed belt of a drive of GRM in order to avoid damage of valves as a result of their blow about the bottoms of pistons.

PERFORMANCE ORDER

1. Manually check freedom of rotation of a roller of a natyazhitel, then pull it here and there, checking on existence люфта in the bearing (see an illustration to paragraph 13). The defective roller is subject to replacement. 2. Attentively examine a gas-distributing belt from both parties, checking it on existence of signs of wear (especially persistent walls of teeths), cracks, cuts, attritions and zamaslivaniye traces (see an accompanying illustration). The defective belt is subject to obligatory replacement. If only run of the engine is not so small, replacement of a belt is recommended to be made regardless of its condition. At all do not establish on the engine an old belt, for all hundred percent being not sure of serviceability of its condition.

Installation

PERFORMANCE ORDER

1. If removed, establish into place cogwheels of shaft (do not forget about segment shponka of wheels of camshafts and internal directing a belt on a cranked shaft). Tighten bolts of fastening of cogwheels of camshafts with demanded effort (see. Specifications). 2. Before installation of a belt make sure that cogwheels of camshafts are established to well-aimed “UP” up. Adjusting labels should appear combined with the index on a back cover of a belt (see an accompanying illustration). At resistance emergence immediately stop a shaft provorachivaniye in order to avoid damage of valves as a result of blow about the bottoms of pistons. Accurately correct the provision of cogwheels of camshafts, then repeat attempt. 3. Temporarily establish on a place and fix a bolt a pulley of a cranked shaft, then turn a shaft (if it was brought down) so that the adjusting label on its cogwheel it was combined with the response index on the case of the oil pump (see an accompanying illustration). 4. Densely put on a belt a cogwheel of a cranked shaft, then lead it under a roller of a natyazhitel and round cogwheels of the water pump and camshafts. Weaken a bolt of a natyazhitel, having provided a belt tension, then temporarily tighten a bolt. 5. Accurately turn a cranked shaft six times in the direction counter-clockwise, then make sure of correctness of an arrangement of adjusting labels of cogwheels of camshafts (see illustrations above). If the cranked shaft is turned with breakthroughs, or got jammed, it is not necessary to apply force as it can lead to damage of valves at blow them about the bottoms of pistons (if adjustment is brought down). Remove a belt and repeat procedure, giving particular attention to combination of adjusting labels. 6. For adjustment of effort of a tension of a belt weaken on a half of turn (180 °) a bolt of a natyazhitel and turn a cranked shaft in the direction counter-clockwise on three teeth for situation VMT. Now tighten a bolt with demanded effort (see. Specifications). 7. Establish into place all components acting in film in the course of dismantle. 8. Adjust efforts of a tension of driving belts (see. Head Routine maintenance). 9. Start the engine and check serviceability of its functioning.
