PROCEDURE
INSTALL CAMSHAFT TIMING GEAR ASSEMBLY
Note
Install the camshaft timing gear assembly onto the camshaft with the lock pin of the camshaft timing gear assembly released.
| *1 | Straight Pin |
| *2 | Groove |
Put the camshaft timing gear assembly together with the straight pin and key groove misaligned as shown in the illustration.
Turn the camshaft timing gear assembly clockwise while pushing it gently toward the camshaft. Push further at the position where the pin fits into the groove.
Check that there is no clearance between the gear fringe and the camshaft.
Tighten the flange bolt with the camshaft timing gear fixed.
Check that the locked in the most retarded position.
INSTALL CAMSHAFT

| *2 | Valve Lash Adjuster Assembly |
| *3 | Valve Stem |
| *4 | Valve Stem Cap |
Make sure that the valve rocker arms are installed as shown in the illustration.
Apply a light coat of engine oil to the camshaft and camshaft journals.
| *a | Paint Mark |
| *b | Timing Mark |
Install the chain onto the camshaft timing gear with the paint mark and the timing mark aligned as shown in the illustration.
Examine the front marks and numbers on the No. 2 camshaft bearing caps and check that the sequence is as shown in the illustration. Then uniformly tighten the bolts, in several steps, in the sequence shown in the illustration.
Note
Tighten each bolt uniformly while keeping the camshaft level.
INSTALL NO. 2 CAMSHAFT
| *1 | No. 1 Valve Rocker Arm Sub-assembly |
| *2 | Valve Lash Adjuster Assembly |
| *3 | Valve Stem |
| *4 | Valve Stem Cap |
Make sure that the valve rocker arms are installed as shown in the illustration.
Install the No. 2 camshaft.
| *1 | Pin |
| *a | Paint Mark |
| *b | Timing Mark |
Hold the chain and align the timing mark on the camshaft timing sprocket with the paint mark of the chain sub-assembly.
Align the alignment pin hole in the camshaft timing sprocket with the alignment pin of the No. 2 camshaft, and install the sprocket onto the No. 2 camshaft.
Temporarily install the bolt.
| *1 | No. 1 Bearing Cap |
| *2 | No. 2 Bearing Cap |
Examine the front marks and numbers on the No. 1 camshaft bearing cap and No. 2 camshaft bearing caps and check that the order is as shown in the illustration. Then uniformly tighten the bolts, in several steps, in the sequence shown in the illustration.
Note
Tighten each bolt uniformly while keeping the camshaft level.
While holding the No. 2 camshaft with a wrench, tighten the bolt.
Tech Tips
Connect the torque wrench and the union nut wrench properly so that they form a straight line when using them.
Use the formula to calculate special torque values for situations where a union nut wrench is combined with a torque wrench Click here.
Remove the bar from the timing chain tensioner.
| *a | Timing Notch |
Turn the crankshaft damper and align the timing notch with the timing mark "0" of the oil pump.
| *a | Paint Mark |
| *b | Timing Mark |
Check that all the pairs of timing marks are aligned.
Apply adhesive to 2 or 3 threads of the screw plug end.
| Adhesive |
