WARNING
Do not loosen or remove the crankshaft pulley bolt without first installing the special tools as instructed in this procedure. The crankshaft pulley and the crankshaft timing sprocket are not keyed to the crankshaft. The crankshaft, the crankshaft sprocket and the pulley are fitted together by friction, using diamond washers between the flange faces on each part. For that reason, the crankshaft sprocket is also unfastened if you loosen the pulley bolt. Before any repair required loosening or removal of the crankshaft pulley bolt, the crankshaft and camshafts must be locked in place by the special tools, otherwise severe engine damage can occur.

  5. Using the crankshaft pulley bolt, turn the crankshaft clockwise to position the No. 1 piston at TDC. The hole in the crankshaft pulley should be in the 6 o'clock position. 
    WARNING
    The special tool 303-465 is for camshaft alignment only. Using this tool to prevent engine rotation can result in engine damage.
