Install the tensioner arm, shaft and plain washer to the cylinder block.
Tightening torque:

35-55 N.m (350-550 kg. cm, 25.82-40.57 lb. ft)

Install the crankshaft sprocket.
NOTE: Confirm if timing marks coincide with.

CAUTION: Align the spacer with a pin, and assemble it exerting even force not to deform the crankshaft sensing blade.

Install the camshaft sprocket.
Align it like initial state as shown on the picture.

CAUTION: When installing camshaft sprocket, tighten the bolt holding hexagonal part of camshaft to prevent it from turning.

Install the auto tensioner to the oil pump case.
CAUTION: At this time the auto tensioner's set pin should be assembled completely.

Align the timing marks of each sprocket and install the timing belt, maintaining the proper belt tension between each shaft in this order.
Crankshaft sprocket --> Idler pulley --> Left bank exhaust camshaft sprocket --> Left bank intake camshaft sprocket --> Water pump pulley --> Right bank intake camshaft sprocket --> Right bank exhaust camshaft sprocket --> Tensioner pulley.

CAUTION:
- As a result of this, position of No. 1 cylinder comes to compression TDC.
- As each camshaft sprocket tends to rotate by itself, pay attention not to injure fingers or other bodily part. Especially be careful with the right bank.
- In case the right bank camshaft sprocket rotates excessively, be cautious not to rotate more than the initial stable position. Always align timing mark of rotating sprocket by turning it reversely. In this case, pay attention not to rotate it reversely from the initial position. (If, with one sprocket fixed at No. 1 compression TDC position, the other sprocket is rotated one revolution clockwise or counter clockwise, then the intake and exhaust valve might interfere each other.)
After installing the timing belt, exert the reverse-directed force to the right bank exhaust camshaft sprocket to give tension on the belt. Holding this state, recheck if each timing mark is correctly positioned.
With tensioner pulley slightly pushing the belt down, tighten the center bolts lightly.
