3.3.3. Top dead point (VMT) of the N1 piston

GENERAL INFORMATION

The highest point of which reaches the N1 piston at the moment of a compression step is accepted to the top dead point.

The N1 piston is located in a forward part of the right number of cylinders from a gas-distributing belt.

PERFORMANCE ORDER
1. Disconnect a wire of the minus plug of the accumulator and, if necessary, unscrew spark plugs.
2. Remove an external cover of a gas-distributing belt.
3. Turn a cranked shaft so that sinkhronizatsionny labels of asterisks of camshafts were directed up and combined with cuts in a cover of a gas-distributing belt (are specified by shooters). Do this procedure as for the right head of cylinders (drawing at the left), and for left (drawing on the right). On each asterisk there are two labels. The table on use of these labels below is provided.
4. Combine a label on a pulley of a cranked shaft with the index (are specified by shooters) on a casing of the oil pump. When labels are combined, the N1 piston is in VMT at the moment of a compression step.
