3.1.4. An order of installation of the piston of 1st cylinder in ВМТ a compression step
THE GENERAL DATA

The prevention

At the procedure description it is supposed that the ignition distributor is established correctly. If it is necessary to expose the distributor define a compression step on a compression in the cylinder, and combine labels of the moment of ignition. 1st cylinder is located about a radiator


Piston installation (or pistons) in ВМТ a compression step is an integral part of many procedures on engine adjustment.

Installation

PERFORMANCE ORDER
1. Translate the check point lever in neutral position. Disconnect a high-voltage wire of the coil of ignition from the central conclusion of a cover of the distributor and connect to weight on the block of cylinders.
2. Uncover the distributor and find on a cover position of a high-voltage wire of a candle of 1st cylinder. If this conclusion is not numbered, define it on a wire from a spark plug.
3. Put a label opposite to a conclusion of a wire of 1st cylinder.
4. Uncover the ignition distributor.
5. Turn коленвал a key (for a head of a bolt of a pulley) or a starter so that the mark in a pulley was combined with a label on a plate in a forward part of the engine. On engine M40 turn коленвал so that position бегунка the distributor corresponded ВМТ a compression step in 1st cylinder, then tighten before dredging coincidence on a flywheel with a label on the block of cylinders, observing through a window in the block.
6. If бегунок specifies in a label put on the case of the distributor the piston of 1st cylinder is in ВМТ a compression step. Otherwise tighten коленвал on one complete revolution clockwise (360 ) and establish the piston of 1st cylinder in ВМТ a compression step. If it is impossible to combine simultaneously labels on a pulley and on the index бегунка it specifies in loss of teeths of a gear wheel or a belt, or on wrong installation of a chain or a belt.
7. Now it is possible to expose in ВМТ a step of compression and other pistons, having put labels opposite to other conclusions to the distributor case according to an operating procedure of cylinders and turning коленвал.
