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





(a) Align the mark plates (yellow) of the No. 2 chain with the timing marks (1 dot mark) of the camshaft timing gears as shown in the illustration.
(b) Apply a small amount 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 with the No. 2 chain installed.





(d) Hold the hexagonal portion of the camshaft with a wrench, and tighten the 2 bolts.
Torque: 100 N*m (1020 kgf*cm, 74 ft.*lbf)
(e) Remove the pin from the No. 2 chain tensioner.

(e) Remove the pin from the No. 2 chain tensioner.


NO. 1 CHAIN SUB-ASSEMBLY





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

HINT: The chain mark plate is orange.





NOTICE: Do not pass the chain over the crankshaft, just put the chain on the crankshaft.





(b) Turn the camshaft timing gear on the bank 1 counterclockwise to tighten the chain between the banks.

NOTICE: If reusing the idle sprocket, align one of the idle sprocket's chain plate marks with one of the chain's chain plates when installing the idle sprocket.





(c) Align the mark plate and timing mark as shown in the illustration and install the chain onto the crankshaft timing gear.

HINT: The chain mark plate is yellow.

(d) Temporarily tighten the pulley set bolt.





(e) Turn the crankshaft clockwise to set it to the bank 1 block bore center line (TDC/compression).
