3.2.3. Installation of the piston of the 1st cylinder in compression step VMT



It is meant that works are performed at the correct installation of the distributor of ignition (on engines of 3,0 l). If it is necessary to redeem the correct situation of the distributor, determine an engine step by feeling of a compression in the 1st cylinder by the turned-out candlelight then combine ignition moment tags (see below).

Installation of the piston of the 1st cylinder in VMT of a step of compression is necessary for performance of adjusting and adjustment works (adjustment of valves, installation of the moment of ignition, etc.).

1. Transfer a control lever transmission to neutral situation. Exclude possibility of operation of ignition, having connected the central wire of the distributor (3,0 l) to weight, or having disconnected the socket on each of 3 coils of ignition (3,4 l). It is necessary to consider that the crankshaft should be turned only clockwise.

2. Designate a conclusion of a candle of the 1st cylinder a tag on the distributor case.
3. Uncover the distributor.
4. Turn the crankshaft clockwise before combination risks on a crankshaft pulley with a tag "0" on a motionless scale.
5. If the index of the runner of the distributor is opposite risks on the distributor case, the piston of the 1st cylinder is in compression step VMT. If the runner is turned on 180 ° from risks, turn the crankshaft on 1 turn then the piston of the 1st cylinder will be exposed in compression step VMT. Thus tags on a scale and a pulley have to be combined, and the index of the runner has to be opposite risks, designating a conclusion of the 1st cylinder.
6. Designate conclusions of other wires according to an engine operating procedure. Turning the crankshaft further clockwise concerning position VMT of the 1st cylinder, it is possible to expose the piston of each cylinder in VMT, combining the index of the runner with tags of conclusions.

7. Turn out a candle of the 1st cylinder and attach the compression measuring instrument through a hose about 150 mm long, having screwed the hose union in an opening for a candle.
8. Turn the crankshaft until pressure of a compression does not start increasing in process of rapprochement of tags on a pulley and on a scale. Having passed tags, remove the measuring instrument and turn further the crankshaft on 2 turns.


The most exact installation of the piston in compression step VMT on such engines is reached by simultaneous combination of tags on a pulley of the crankshaft and on asterisks of cam-shafts (see subsection 3.1.7).
