Removal
| PERFORMANCE ORDER |
| 1. Uncover heads of the block of cylinders (see subsection 3.1.1.3). |
| 2. Establish the piston of the 1st cylinder in VMT of a step of compression (see subsection 3.1.1.2). Put a paint droplet on labels of VMT of gear wheels of a cam-shaft (labels are in a place of gearing of gear wheels, their arrangement coincides with the line of the section of a head of cylinders and covers of a head of cylinders. |
Prevention
On gear wheels of cam-shafts there are two sets of labels. The labels coinciding in situation VMT correspond only to cam-shaft orientation in VMT, other labels are used for the correct orientation of cam-shafts at their installation.
|
| 3. Remove the ignition distributor (see subsection 3.3.6).Снимите a conducted gear wheel of a cam-shaft (see subsection 3.1.1.8) and a gear belt (see subsection 3.1.1.6). |
|
4. Measure axial люфт each of cam-shafts by means of a display head. Establish the indicator on a zero. Shake a cam-shaft with force in the longitudinal direction (on itself and from itself) and define axial люфт. If люфт exceeds maximum permissible, a cam-shaft and (or) a head of the block of cylinders are subject to replacement. |
|
5. Turn cam-shafts so that the technological opening under an auxiliary bolt in a gear wheel of a cam-shaft was located directly over edge of a head of cylinders. In this situation cams corresponding to the first and third cylinder of a cam-shaft of inlet valves should rest under the influence of springs against pushers with identical efforts. |
Prevention
The cam-shaft should be exposed in such situation that at removal of a cam-shaft to avoid breakage of a head of cylinders or the cam-shaft.
|
|
6. Unscrew two bolts and uncover a forward basic neck of a cam-shaft of inlet valves. |
|
7. Attach an auxiliary gear wheel to the main gear wheel one of prepared bolts М6, having screwed it in a carving opening in a gear wheel. |
| 8. In sequence, return specified, (see fig. Sequence of an inhaling of bolts of covers of basic necks of a cam-shaft of inlet valves (engines of 1,6 l and 1,8 l)) unscrew for some receptions bolts of other covers of basic necks of a cam-shaft of inlet valves. Turn on each bolt on 1/4 turns at one time, until then while bolts will not begin to turn away by hand. Remove covers, having lifted them vertically up. |
Prevention
In process of an otpuskaniye of bolts of an average cover be convinced that the cam-shaft starts to move equally in support in the vertical direction. If any neck of a cam-shaft ceases to move freely, or the cam-shaft is released with a distortion (that is found on cams), repeat procedure of an otvorachivaniye of bolts of covers of basic necks, previously having tightened them with the set moment in the specified sequence. It is forbidden to take a cam-shaft with effort application.
|
| 9. Get a cam-shaft, having raised it up. |
|
10. Turn a cam-shaft of final valves so that the pin (it is specified in drawing) was turned approximately at 5 o'clock. |
| 11. Unscrew bolts of fastening of a forward cover of a cam-shaft of final valves (from a gear belt), uncover also an epiploon. |
Prevention
The cover should act in film freely. If the cover does not give in, leave it on a place with the turned-on bolts.
|
| 12. In sequence, return specified, (see fig. Sequence of an inhaling of bolts of covers of basic necks of a cam-shaft of inlet valves (engines of 1,6 l and 1,8 l)) unscrew for some receptions bolts of other covers of basic necks of a cam-shaft of final valves. Turn on each bolt on 1/4 turns at one time until bolts will not begin to turn away by hand. Remove covers, having lifted them vertically up. |
Prevention
In process of an otpuskaniye of bolts of an average cover be convinced that the cam-shaft starts to move equally in support in the vertical direction. If any neck of a cam-shaft ceases to move freely, or the cam-shaft is released with a distortion (that is found on cams), repeat procedure of an otvorachivaniye of bolts of covers of basic necks, previously having tightened them with the set moment in the specified sequence. It is forbidden to take a cam-shaft with effort application.
|
| 13. Get a cam-shaft of final valves, having raised it up. |
|
14. Wipe from oil adjusting washers of pushers, put labels with a marker and remove pushers together with adjusting washers. |
| |
15. Store covers of basic necks, pushers and washers in that order in which these details were established, without allowing their hashing. |
| 16. Clamp a cam-shaft of inlet valves for a six-sided neck in a vice with soft sponges. |
|
17. A natural two persistent pins turn an auxiliary gear wheel clockwise, then unscrew the auxiliary bolt, fixing the main and auxiliary gear wheel, and carefully weaken effort, giving the chance to an auxiliary gear wheel to turn counter-clockwise before spring liberation. |
|
18. Take a lock ring of an auxiliary gear wheel, operating special пассатижами. |
|
19. Now it is possible to remove a spring washer (1), an auxiliary gear wheel (2) and a spring of an auxiliary gear wheel (3). |
|
Condition check
Installation
| PERFORMANCE ORDER |
| 1. Establish pushers of final valves on former places, whether previously having greased pushers with greasing on the basis of a molybdenum disulfide assembly greasing, openings in a head of cylinders. Be convinced of safety of adjusting laying on pushers. |
| 2. Grease basic necks and cams of a cam-shaft of final valves with greasing on the basis of a molybdenum disulfide, or assembly greasing. |
|
|
3. Lay a cam-shaft of final valves in a head of cylinders so that the pin was turned approximately at 5 o'clock. |
| 4. Apply a thin film RTV type hermetic on a contact surface of a forward cover of a cam-shaft of final valves with a head of cylinders. |
Prevention
The cover should be established at once after hermetic drawing, before its hardening.
|
| 5. Establish covers of a cam-shaft of final valves on former places, observing numbering and orientation of arrows which should be directed towards a gear belt. |
| 6. Evenly, in stages and observing sequence, tighten bolts of fastening of covers with the moment specified in subsection 3.1.1.1). To wrap bolts on 1/4 turns at one time. |
| 7. Establish a new epiploon of a cam-shaft, being guided by the description in subsection 3.1.1.8. |
| 8. Collect a cam-shaft of inlet valves with springs and an auxiliary gear wheel. |
|
|
| 9. Establish a spring washer (1), an auxiliary gear wheel (2) and a spring of an auxiliary gear wheel (3) (a photo at the left), fix all details a lock ring (a photo on the right). |
| 10. Being guided by item 7, wrap an auxiliary bolt. |
| 11. Establish pushers of final valves on former places, whether previously having greased pushers with greasing on the basis of a molybdenum disulfide assembly greasing. Be convinced of safety of adjusting laying on pushers. |
| 12. Grease basic necks and cams of a cam-shaft of inlet valves with greasing on the basis of a molybdenum disulfide, or assembly greasing. |
|
13. Soriyentiruyte a cam-shaft of final valves so that the pin was located between the directions for 9 and 10 hours. |
| 14. Soriyentiruyte cam-shafts of inlet and final valves, having combined adjusting labels on their gear wheels (see fig. Adjusting labels on cam-shaft gear wheels). |
Prevention
On some engines there are two sets of labels. The labels of VMT marked with paint (see item 2) not to use. Adjusting labels differ that are duplicated with external and inside of gear wheels of cam-shafts.
|
| 15. Turn a gear wheel of an inlet cam-shaft on a gear wheel final before installation of a final cam-shaft in pro-points under basic necks to a head of cylinders, thus slightly shake a gear wheel of a final cam-shaft on an identical corner in both directions. |
| 16. Establish covers of a cam-shaft of inlet valves on former places, observing numbering of covers and orientation of arrows which should be directed towards a gear belt. |
| 17. Evenly, in stages and observing sequence, tighten bolts of fastening of covers with the moment specified in subsection 3.1.1.1). To wrap bolts on 1/4 turns at one time. |
| 18. Turn out an auxiliary bolt from a gear wheel of a cam-shaft of inlet valves. |
| 19. Establish on a cam-shaft of final valves a conducted gear wheel and tighten a gear wheel bolt with the moment specified in subsection 3.1.1.1). At an inhaling of a bolt hold a cam-shaft a key for a six-sided neck. |
| 20. Establish a gear belt (see subsection 3.1.1.6). |
| 21. Other operations on installation are carried out upside-down. |
