Camshaft Gear

The installation of timing chain and sprockets begins with using a wrench to position the Camshaft timing marks while the wrench touches the hexagonal region of the camshafts. Begin by initializing the Camshaft rotation to bring the timing marks into proper position followed by moving the Crankshaft until its keyway points upwards. Leverage two bolts (1, 2) to fasten the timing chain shoe then tighten them to 10 nm (89 inch lbs.). Install the timing chain and Crankshaft timing sprocket before placing the timing chain onto the camshafts timing sprockets. Position the timing marks properly before moving forward. Affix the timing chain dampener using one bolt followed by a bolt torque of 18 nm (14 ft. Lbs.).

The first step involves removing the Timing Chain dampener bolts and Timing Chain dampener followed by the Timing Chain shoe bolts and finally the Timing Chain shoe. Crankshaft sprocket and Timing Chain need simultaneous removal during the procedure.

Remove the timing chain shoe bolts and the timing chain shoe.
