Installation

INSTALLATION
1. PLACE CYLINDER HEAD ON CYLINDER BLOCK

- If any cylinder head bolt is broken or deformed, replace it.

a) Apply a light coat of engine oil on the threads and under the heads of the cylinder head bolts.





b) Install and uniformly tighten the 10 cylinder head bolts and plate washers in several passes, in the sequence shown.
Torque: 39 Nm (400 kgf-cm, 29 ft. lbs.)
If any of the cylinder head bolts does not meet the torque specification, replace the cylinder head bolt.

3. ASSEMBLE EXHAUST CAMSHAFT





a) Mount the hexagon wrench head portion of the camshaft in a vise.

SST 09960-10010 (09962-01000, 09963-00500)
4. INSTALL CAMSHAFTS

NOTICE:
Since the thrust clearance of the camshaft is small, the camshaft must be kept level while it is being installed. If the camshaft is not kept level, the portion of the cylinder head receiving the shad thrust may crack or be damaged, causing the camshaft to seize or break. To avoid this, these steps should be carried out.

a) Install the intake camshaft.
1) Apply MP grease to the thrust portion of the intake camshaft.





2) Place the intake camshaft with knock pin facing upward of camshaft angle on the cylinder head.





3) Install the bearing caps in their proper locations.
4) Apply a light coat of engine oil on the threads and under the heads of the bearing cap bolts.





5) Install and uniformly tighten the 10 bearing cap bolts in several passes, in the sequence shown.
Torque: 15.5 Nm (160 kgf-cm, 12 ft. lbs.)
b) Install the exhaust camshaft.
1) Apply MP grease to the thrust portion of the exhaust camshaft.





2) Engage the exhaust camshaft gear to the intake camshaft gear by matching the timing marks (1 and 2 dots) on each gear.

NOTICE: There are also timing marks (for TDC) on each gear as shown in the illustration. Do not use these marks.

3) Roll down the exhaust camshaft onto the bearing journals while engaging gears with each other.





4) Install the bearing caps in their proper locations.
5) Apply light coat of engine oil on the threads and under the heads of the bearing cap bolts.





6) Install and uniformly tighten the 10 bearing cap bolts in several passes, in the sequence shown.
Torque: 15.5 Nm (160 kgf-cm, 12 ft. lbs.)
7) Remove the service bolt.
8) Check that the intake and exhaust camshafts turn smoothly.





5. SET NO.1 CYLINDER TO TDC/COMPRESSION

Torque: 73.5 Nm (750 kgf-cm, 54 ft. lbs.)
7. INSTALL CHAIN TENSIONER





a) Place a new gasket so that the front mark is toward the front side.





b) Release the ratchet pawl, fully push in the plunger and apply the hook to the pin so that the plunger cannot spring out.
c) Turn the crankshaft pulley clockwise to provide some slack for the chain on the tensioner side.

NOTICE: Do not turn the pulley counterclockwise.





d) Push the tensioner by hand until it touches the head installation surface, then install the 2 nuts.
e) Tighten the 2 nuts.
Torque: 21 Nm (210 kgf-cm, 15 ft. lbs.)
f) Check that the hook of the tensioner is not released.

NOTICE: If the plunger springs out during installation of the chain tensioner, repeat the operation in step b) before installing the tensioner.





8. SET CHAIN TENSIONER
Turn the crankshaft to the left so that the hook of the chain tensioner is released from the pin of the plunger, causing the plunger to spring out and the slipper to be pushed in to the chain.





HINT: If the plunger does not spring out, press the slipper into the chain tensioner with a screwdriver or your finger so that the hook is released and the plunger springs out.





9. CHECK VALVE TIMING
a) Turn the crankshaft pulley, and align its groove with timing mark "0" of the timing chain cover.

NOTICE: Always turn the crankshaft clockwise.

b) Check that the timing marks (1 and 2 dots) of the camshaft drive and driven gears are in straight line on the cylinder head surface as shown in the illustration.
If not, turn the crankshaft 1 revolution (360°) and align the marks as above.
