Toyota:: Camry XV20:: Top Dead Point (TDP) of the N1 piston

3.2.3. Top Dead Point (TDP) of the N1 piston

The highest point which is reached by the N1 piston at the time 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.

Installation

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 bent shaft so that synchronizing tags of asterisks of camshafts were directed up and combined with cuts in a cover of a gas-distributing belt. On each asterisk there are two tags (see the table of the Tag of the camshaft).
	4. For installation of the piston in VMT connect the special measuring instrument of pressure in a spark plug opening.
	5. Combine a cut in a pulley of a bent shaft with a mark zero (shooter) on a plate with synchronizing tags. When tags are combined, the N1 piston is in VMT at the time of compression.
