Instructions for installing the piston of the first cylinder in the TDC position of the compression stroke on a VAZ 2110 car Instructions for installing the piston of the first cylinder in the TDC position of the compression stroke on a VAZ 2110 car.

Turn the crankshaft only by the bolt securing the pulley to it (do not turn the crankshaft by the camshaft pulley).

Recommendation for installing the piston of the first cylinder in the TDC position

Since it is inconvenient to turn the crankshaft by the bolt attaching the pulley to it, you can do this in the following ways:

  1. Include any gear (preferably 4th) and slowly roll the car until the mark on the camshaft pulley matches the mark on the rear cover of the camshaft drive belt.
  2. Shift into any gear and hang out one of the front wheels. Then turn the suspended wheel until the mark on the camshaft pulley matches the mark on the rear cover of the camshaft drive belt.

The piston of the 1st cylinder in the TDC position (top dead center) of the compression stroke is set so that when carrying out work related to the removal of the camshaft drive belt, the valve timing is not disturbed. If the valve timing is violated, the engine will not work normally.

Set the TDC according to the mark on the camshaft pulley (when installing according to the marks on the flywheel or crankshaft pulley, the piston of either the 1st or 4th cylinder may be in this position). After that, be sure to make sure that the marks on the flywheel or on the crankshaft toothed pulley match (if the alternator drive pulley is removed). If at the same time the mark on the flywheel or crankshaft pulley does not match, then the valve timing is broken (the piston of the 1st cylinder is not set at TDC). In this case, it is necessary to remove the camshaft drive belt and turn the crankshaft until the marks are aligned.
