    You may need to get a workshop manual because as you assemble the timing chain and sprockets, there might be pre-alignment procedures---I don't know how much of the engine you've taken apart, so that may or may not apply.

    But I'll get you started:

    Rotate the crankshaft so that the following conditions are met:

    • The number 1 (front most) cylinder is at the Top Dead Center (TDC) position.
    • The keyway on the crankshaft (5) aligns with the mark on the engine block (4).
    • The arrow (3) on the idler sprocket is pointing upward.
    • The guide pins (1) on the camshaft sprockets line up with the notches (6) on the cylinder head.

    NOTE: The timing chains need to be aligned to specific locations during assembly. Refer to procedure for further information.
