Inspection

Spockets, Tensioner, Idler
Check the camshaft sproket, crankshaft sprocket, tensioner pulley, and idler pulley for abnormal wear, cracks, or damage. Replace as necessary.
Inspect the tensioner pulley and the idler pulley for easy and smooth rotation and check for play or noise.
Replace as necessary.

Replace the pulley if there is a grease leak from its bearing.
Timing Belt
Check the belt for oil or dust deposits.
Replace, if necessary.
Small deposits should be wiped away with a dry cloth or paper. Do not clean with solvent.
When the engine is overhauled or belt tension adjusted, check the belt carefully. If any of the following flaws are evident, replace the belt.
Do not bend, twist or turn the timing belt inside out.
Do not allow the timing belt to come into contact with oil, water and stem.

Installation

Install the camshaft sprocket and tighten the bolt to the specified torque.
Temporarily install the camshaft sprocket bolt.
Hold the hexagonal head wrench (A) portion of the camshaft with a wrench (B), and tighten the camshaft sprocket (C) bolt.
Tightening torque
Camshaft sprocket bolt :
98.1 117.7Nm (10.0 12.0kgf.m, 72.3 86.8lb-ft)

Install cylinder head cover.
Install cylinder head cover (A) and the twelve bolts (B).

Tightening torque :
7.8 9.8Nm (0.8 1.0kgf.m, 5.8 7.2lb-ft)
Install the PCV hose (A) and breather hose (B).
Install the accelerator cable (C) and the auto-cruise cable (D) from the cylinder head cover.

Install the spark plug cable.
Install the crankshaft sprocket (A).

Align the timing marks of the camshaft sprocket (A) and crankshaft sprocket (B) with the No. 1 piston placed at top dead center and its compression stroke.

Install the idler pulley (A) and tighten the bolt (B) to the specified torque.
Tightening torque
Idler pulley bolt :
42.2 53.9Nm (4.3 5.5kgf.m, 31.1 39.8lb-ft)

Install the timing belt tensioner loosely enough for the adjuster to rotate. Make sure that the stopper of base is leaning against the lowering sealing cap on the cylinder head.
Belt so as not give slack at each center of shaft. Do as following procedures when installing timing belt.
Crankshaft sprocket (A) → Idler pulley (B) → Camshaft sprocket (C) → timing belt tensioner (D).
(The tensioner can be installed after the timing belt.)

Check the alignment of the timing marks on each sprocket.
Remove the pin fixing the tensioner arm.
Using a hex wrench, turn the adjuster counterclockwise to make the indicator of the arm (A) located at the center of the base notch.

Do not rotate the adjuster clockwise.
It will result in auto tensioner's functional problem.
Tightening tensioner bolt with fixing the indicator not to move.
Tightening torque
Tensioner bolt :
22.6 28.4Nm (2.3 2.9kgf.m, 16.6 21.0lb-ft)
Turn the crankshaft two revolutions in the operating direction (clockwise) and check that the indicator is in the center of base.
If the indicator is not located at the center of base, slacken the bolt and repeat the abore procedure.
Install the timing belt lower cover (A) with 5 bolts (B).
Tightening torque
Timing belt cover bolt :
7.8 9.8Nm (0.8 1.0kgf.m, 5.8 7.2lb-ft)

Install the flange and crankshaft pulley (A).
Make sure that crankshaft sprocket pin fits the small hole in the pulley.
