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

The prevention

It is meant that works are carried out at correct installation of the distributor of ignition (on engines 3,0). If it is necessary to redeem correct position of the distributor define an engine step on sensation of a compression in 1st cylinder at the turned out candle then combine labels of the moment of ignition (see more low).

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

1. Translate a control lever transmission in neutral position. Exclude possibility of operation of ignition, having connected to weight the central wire of the distributor (3,0), or having disconnected a socket on each of 3 coils of ignition (3,4). It is necessary to consider that коленвал it is necessary to turn only clockwise.
Installation order on engines of 3,0 l
2. Designate a conclusion of a candle of 1st cylinder a label on the distributor case.
3. Uncover the distributor.
4. Turn коленвал clockwise before combination risks on a pulley коленвала with a label "0" on a motionless scale.
5. If the index бегунка the distributor is opposite risks on the distributor case the piston of 1st cylinder is in ВМТ a compression step. If бегунок it is turned on 180 ° from risks turn коленвал on 1 turn then the piston of 1st cylinder will be exposed in ВМТ a compression step. Thus labels on a scale and a pulley should be combined, and the index бегунка should be opposite the risks, 1st cylinder designating a conclusion.
6. Designate conclusions of other wires according to an engine operating procedure. Turning коленвал further clockwise concerning position ВМТ of 1st cylinder, it is possible to expose in ВМТ the piston of each cylinder, combining the index бегунка with labels of conclusions.
Installation order on engines of 3,4 l
7. Turn out a candle of 1st cylinder and attach a compression measuring instrument through a hose in length about 150 mm, having screwed the hose union in an aperture for a candle.
8. Turn коленвал until then while pressure of a compression will not start to raise in process of rapprochement of labels on a pulley and on a scale. Having passed labels, remove a measuring instrument and turn долее коленвал on 2 turns.

The prevention

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