Section 207 (Engine Mechanical): Camshaft: Installation

1. Put the camshaft timing gear assembly and camshaft together with the straight pin of the groove.
2. Turn the camshaft timing gear assembly clockwise while pushing it gently toward the camshaft. When the pin fits the groove, push to ensure a good fit.

   NOTE: Do not turn the camshaft timing gear in the retard direction (clockwise).
3. Check that there is no clearance between the gear flange and the camshaft.
4. Tighten the flange bolt with the camshaft timing gear fixed.

   Torque: 64 N*m (653 kgf*cm, 47 ft.*lbf) 

   NOTE:

   • Do not lock the camshaft timing gear assembly when tightening the bolt.
   • Release the lock pin of the camshaft timing gear assembly first, and tighten the bolt when the lock pin is locked in the most retarded position.
   • Tightening the bolts with the lock pin locked could cause breakage of the lock pin.
5. Check that the camshaft timing gear assembly moves smoothly in the retard direction (clockwise) and is locked in the most retarded position.

1. Apply a light coat of engine oil to the camshaft and camshaft journals.
2. Install the chain onto the camshaft timing gear with the paint mark and the timing mark aligned as shown in the illustration.

3. Examine the front marks and numbers on camshaft bearing cap No. 2 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.

   Torque: 13 N*m (129 kgf*cm, 9.4 ft.*lbf) 

   NOTE: Tighten each bolt uniformly while keeping the camshaft level.

5. Examine the front marks and numbers on camshaft bearing caps No. 1 and No. 2 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.

   Torque: for bearing cap No. 2 

   13 N*m (129 kgf*cm, 9.4 ft.*lbf) for bearing cap No. 1 23 N*m (235 kgf*cm, 17 ft.*lbf) 

   NOTE: Tighten each bolt uniformly while keeping the camshaft level.
