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

GENERAL INFORMATION

Prevention

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, then 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.).

PERFORMANCE ORDER
1. Transfer a control lever transmission to neutral situation. Exclude a 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.
Installation order on engines of 3,0 l
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, then the piston of the 1st cylinder is in compression step VMT. If the runner is turned on 180 ° from risks, then turn the crankshaft on 1 turn then the piston of the 1st cylinder will be exposed in compression step VMT. At the same time 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 the provision of 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.
Installation order on engines of 3,4 l
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 begin to increase 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.

Prevention

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).
