Sequence of an inhaling of bolts of covers of basic necks of a cam-shaft of inlet valves (engines of 1,3 l)


Adjusting tags on gear wheels of cam-shafts of inlet and final valves


Two sets of adjusting tags on engines of 1,3 l

At mutual orientation of cam-shafts it is forbidden to use the adjusting tags intended for other purposes.
A. Cam-shaft of final valves
B. Cam-shaft of inlet valves
1. Adjusting tags
2. Adjusting tags of VMT

Prevention

Before performance of work prepare two bolts with a carving of 6х1 mm and 15-20 mm long which will be used when dismantling as auxiliary.


Removal

PERFORMANCE ORDER
1. Uncover heads of the block of cylinders (see subsection 3.1.1.3).
2. Install the piston of the 1st cylinder in compression step VMT (see subsection 3.1.1.2).
3. Remove the ignition distributor (see subsection 3.3.6). Remove the conducted cam-shaft gear wheel (see subsection 3.1.1.8) and a gear belt (see subsection 3.1.1.6).
4. Measure an axial side play of each of cam-shafts by means of an indicator head. Install the indicator on zero. Shake a cam-shaft with a force in the longitudinal direction (on yourself and from yourself) and define an axial side play. If the side play exceeds maximum permissible, the cam-shaft and (or) a head of the block of cylinders are subject to replacement.
5. Turn a cam-shaft so that the technological opening under an auxiliary bolt was turned vertically up. In this provision of a cam-shaft cams of the first and third cylinder have to 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. Turn off four bolts and remove forward covers of basic necks of cam-shafts of final and inlet valves. Get a cap of a cam-shaft of inlet valves, remove an epiploon of a cam-shaft of final valves.
7. Attach an auxiliary gear wheel to the main gear wheel in advance prepared bolt with a carving of M6 and 15-20 mm long, having screwed it in a carving opening in the main gear wheel of a cam-shaft.
8. In sequence return specified (see rice. Sequence of an inhaling of bolts of covers of basic necks of a cam-shaft of final valves (engines of 1,3 l)) turn off bolts of other covers of basic necks of a cam-shaft of final valves for some receptions. Turn off each bolt on 1/4 turns at one time until bolts do not begin to turn away by hand. Uncover, having lifted them vertically up.

Prevention

In process of an otpuskaniye of bolts of an average cover be convinced that the cam-shaft starts moving 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 application of effort.


9. Get a cam-shaft of final valves, having raised it up.
10. In sequence, return specified (see rice. Sequence of an inhaling of bolts of covers of basic necks of a cam-shaft of inlet valves (engines of 1,3 l)) turn off bolts of other covers of basic necks of a cam-shaft of inlet valves for some receptions. Turn off each bolt on 1/4 turns at one time until bolts do not begin to turn away by hand. Uncover, having lifted them vertically up.
11. Wipe adjusting washers of pushers from oil, put tags with a marker and remove pushers and adjusting washers.
12. Store covers of basic necks, pushers and washers in that order in which these details were established,
13. Clamp a cam-shaft of inlet valves for a six-sided neck in a vice with soft sponges.
14. A key with two persistent pins turn an auxiliary gear wheel clockwise, then turn off the auxiliary bolt fixing the main and auxiliary gear wheel and carefully weaken effort, giving the chance to an auxiliary gear wheel to turn counterclockwise before liberation of a spring.
15. Take a lock ring of an auxiliary gear wheel, working with special passatizha.
16. Remove a spring washer (1), an auxiliary gear wheel (2) and a spring of an auxiliary gear wheel (3).

Check of a condition of details

PERFORMANCE ORDER
1. Measure distance between the ends of a spring of an auxiliary gear wheel in a free state and compare to the standard. If the distance differs from standard, replace a spring.
2. Check a condition of adjusting laying and pushers. Existence of chips and deep development is not allowed.
3. Measure diameter of each pusher, then measure diameter of the interfaced opening in a head of cylinders. Define gaps in pushers as a difference of diameter of the interfaced opening in a head of cylinders and diameter of a pusher. If the gap exceeds norm, a pusher (pushers) or a head of cylinders should be replaced.
4. Check existence on basic necks and cams of a cam-shaft of wear tracks – grooves, poles, a navolakivaniye of metal and traces of an overheat (sites of bluish color, or the painted sites). Check existence on each cam of peeling of the tempered layer.
5. Measure by a micrometer the size of each cam of a cam-shaft and compare the sizes to the standard. If the size at least is less than one cam standard, replace a cam-shaft.
6. Measure by a micrometer diameter of basic necks of a cam-shaft and compare the sizes to the standard. If diameter at least is less than one basic neck standard, replace a cam-shaft.
7. Check gaps in basic necks for each cam-shaft.
8. Clear basic necks of a cam-shaft and cover of basic necks in solvent for varnishes or in acetone.
9. Carefully lay a cam-shaft(s) in a head of the block of cylinders without pushers, adjusting washers and an auxiliary gear wheel of a cam-shaft of inlet valves. Availability of oil on necks is not allowed.
10. Across each basic neck of a cam-shaft lay pieces of a plastic calibration wire of "Plastigauge".
11. Establish covers of basic necks of cam-shafts so that shooters were directed towards a gear belt.
12. Tighten bolts with the set moment turning each bolt on 1/4 turns at one time.

Prevention

Turn of a cam-shaft with the inserted plastic caliber is not allowed.


13. Turn off bolts and uncover.
14. Compare width of the crushed wire (in the widest place) to a scale on packing.
15. If the gap at least in one of necks exceeds norm, the cam-shaft and (or) a head of the block of cylinders are subject to replacement.
16. Scrape off a nail or plastic, the plastic remains, thus do not scratch a basic neck or an internal surface of a cover.
17. At temporarily established covers of basic necks check a gap in gearing of gear wheels of cam-shafts. Holding a key one of cam-shafts for a six-sided neck, check the size of movement of a gear wheel of other cam-shaft. Compare result to the standard. If the gap is higher than norm, replace both cam-shafts.
