TIMING CHAIN REMOVAL


  1. REMOVE TIMING CHAIN COVER SUB-ASSEMBLY


  2. SET NO. 1 CYLINDER TO TDC / COMPRESSION


    1. Temporarily install the pulley set bolt.

    2. Rotate the crankshaft clockwise so that the timing marks on the crankshaft timing gear and camshaft timing gears are as shown in the illustration.

      Tech Tips

      If the timing marks do not align, rotate the crankshaft clockwise again and align the timing marks.
