Note:
For detailed installation procedures refer to Engine Overhaul, Reassembly Part 2 step 34

INSTALL NO. 2 CHAIN TENSIONER ASSEMBLY

(a) Install the No. 2 chain tensioner assembly with the bolt.

Torque : 21 Nm (214 kgf-cm, 15 ft-lbf)

(b) While pushing in the tensioner, insert a pin of dia 1.0 mm (0.039 in.) into the hole to fix it.

INSTALL 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 sub-assembly installed.

(d) Using SST to hold the hexagonal portion of each camshaft, tighten the bolts of the camshaft timing gear assembly and the camshaft timing exhaust gear assembly RH.

SST : 09922-10010

Torque : 100 Nm (1020 kgf-cm, 74 ft-lbf)

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

INSTALL NO. 3 CHAIN TENSIONER ASSEMBLY

(a) Install the No. 3 chain tensioner assembly with the bolt.

Torque : 21 Nm (214 kgf-cm, 15 ft-lbf)

(b) While pushing in the tensioner, insert a pin of dia 1.0 mm (0.039 in.) into the hole to hold it.

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

(a) Align the mark plate (yellow) with the timing marks (2-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 LH with the No. 2 chain sub-assembly installed.

(d) Using SST to hold the hexagonal portion of each camshaft, tighten the bolts of the camshaft timing gear assembly and the camshaft timing exhaust gear assembly LH.

SST : 09922-10010

Torque : 100 Nm (1020 kgf-cm, 74 ft-lbf)

(e) Remove the pin from the No. 3 chain tensioner assembly.

INSTALL CHAIN SUB-ASSEMBLY

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

HINT
The camshaft mark plates are orange.

(b) Do not pass the chain over the crankshaft, just temporarily place it on the crankshaft.

NOTICE:
When the idle sprocket assembly 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 marks 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).

INSTALL NO. 1 CHAIN TENSIONER ASSEMBLY

(a) Move the stopper plate upward to release the lock, and push the plunger deep into the tensioner.

(b) Move the stopper plate downward to set the lock, and insert a hexagon wrench into the hole of the stopper plate.

(c) Install the chain tensioner with the 2 bolts.

Torque : 10 Nm (102 kgf-cm, 7 ft-lbf)

(d) Remove the hexagon wrench of the chain tensioner.

INSPECT VALVE TIMING

(a) Check the camshaft timing marks.

NOTICE:
* Check each timing mark from a viewpoint directly inline with the center of the camshaft and the timing mark on each camshaft timing gear.
* If the timing marks are checked from any other viewpoint, the valve timing may appear misaligned.
(b) Check that each camshaft timing mark is positioned as shown in the illustration.

HINT
For the intake camshaft:

Be sure to check mark A at the point when marks B, C, and D are positioned in line. If the marks are checked from any other viewpoint, they cannot be checked correctly.
