  20. SET NO. 1 CYLINDER TO TDC/COMPRESSION

    1. A202382C05

      *1

      Timing Pointer

      *2

      Timing Mark

      Turn the crankshaft pulley clockwise to align the timing mark on the crankshaft pulley with the timing pointer of the timing chain cover sub-assembly.

      *2

      Timing Mark

      Make sure that the timing mark of the camshaft timing sprocket is at the top.

      Tip:

      If the timing mark is not at the top, turn the crankshaft pulley 1 revolution so that the timing mark is at the top (set the No. 1 cylinder to TDC/compression).

    3. Put a matchmark on the timing chain plate that is aligned with the timing mark of the camshaft timing sprocket.

      Tip:

      The timing chain has 2 yellow-colored plates. If either of them is aligned with the timing mark of the camshaft timing sprocket, this step can be omitted.

    4. A202384N02

      Turn the crankshaft pulley by approximately 90° in the direction of engine revolution from the point where the No. 1 piston is set to TDC/compression so that the lifted valve and piston do not contact each other when removing the camshaft.
