2. Remove the oil seal using a screwdriver.

Chain Tensioner (RH) Disassembly Note

1. Before removing chain tensioner (RH), turn the crankshaft clockwise to position the crankshaft keyway in the 11 o'clock position.

2. Verify that marks on the camshaft sprockets are aligned.

3. Turn the crankshaft clockwise to position the crankshaft keyway in the 3 o'clock position. (camshafts (RH) are in the neutral position.)

4. Place alignment marks on the timing chain corresponding to each of the alignment marks on the timing sprocket.

5. Hold the timing chain tensioner ratchet lock mechanism away from the ratchet stem with a thin screwdriver.

6. Slowly press the tensioner piston.

7. Hold the tensioner piston with a 1.5 mm {0.06 in} wire or paper clip.

Camshaft (RH) Disassembly Note

1. Before removing the camshaft, inspect the following.

(1) Camshaft end play (See CAMSHAFT END PLAY INSPECTION.)

(2) Camshaft journal oil clearance (See CAMSHAFT OIL CLEARANCE INSPECTION.)

Caution

• Remove the camshaft bearing thrust caps 1R and 5R first. Do not loosen any of the other bolts until the thrust caps are removed, or damage to the thrust caps may occur.

Note

• The camshaft bearing caps are numbered to make sure they are assembled in their original positions. When removed, keep the bearing caps with the cylinder head they were removed from. Do not mix the caps.

2. Remove the camshaft cap bolts in the order indicated in the figure in several passes.

Chain Tensioner (LH) Disassembly Note

1. Before removing chain tensioner (LH), turn the crankshaft clockwise 1 and 2/3 turns to position the crankshaft keyway in the 11 o'clock position. (camshafts (LH) are in the neutral position.)

2. Place alignment marks on the timing chain corresponding to each of the alignment marks on the timing sprocket.

3. Press and hold the tensioner piston by following Step 4 to 6 in Chain Tensioner (RH) Disassembly Note. (See Chain Tensioner (RH) Disassembly Note.)

Camshaft (LH) Disassembly Note

1. Before removing the camshaft, inspect the following.

(1) Camshaft end play (See CAMSHAFT END PLAY INSPECTION.)

(2) Camshaft journal oil clearance (See CAMSHAFT OIL CLEARANCE INSPECTION.)

Caution

• Remove the camshaft bearing thrust caps 1R and 5R first. Do not loosen any of the other bolts until the thrust caps are removed, or damage to the thrust caps may occur.

Note

• The camshaft bearing caps are numbered to make sure they are reassembled in their original position. When removed, keep the bearing caps with the cylinder head they were removed from. Do not mix the caps.

2. Remove the camshaft cap bolts in the order indicated in the figure in several passes.
