CAMSHAFT TIMING GEARS AND NO. 2 CHAIN (for Bank 1)





a. Align the mark plate (yellow) with the timing marks (1-dot mark) of the camshaft timing gears as shown in the illustration.
b. Apply a light coat of engine oil to the bolt threads and bolt-seating surface.
c. Align the knock pin of the camshaft with the pin hole of the camshaft timing gear. Install the camshaft timing gear and camshaft timing exhaust gear RH with the No. 2 chain installed.





d. Hold the hexagonal portion of the camshaft with a wrench, and tighten the 2 bolts.
Torque: 100 Nm (1,020 kgf-cm, 74 ft. lbs.)
e. Remove the pin from the chain tensioner.

CHAIN SUB-ASSEMBLY





a. Align the mark plate and timing mark as shown in the illustration and install the chain.

HINT: The camshaft mark plate is orange.





b. Do not pass the chain over the crankshaft, just put it on it.





c. Turn the camshaft timing gear assembly on the RH bank counterclockwise to tighten the chain between the banks.

NOTICE: When the idle sprocket is reused, align the chain plate with the mark where the plate had been in order to tighten the chain between the banks.





d. Align the mark plate and timing mark as shown in the illustration and install the chain onto the crankshaft timing sprocket.

HINT: The crankshaft mark plate is yellow.

e. Temporarily tighten the pulley set bolt.





f. Turn the crankshaft clockwise to set it to the RH block bore center line (TDC/compression).
