Timing Belt: Installation

Check the belt for any defects as shown in the illustration. Also, check the points below.

1. If there is premature parting:
   • Check for proper installation.
   • Check the timing cover gasket for damage and proper installation.
2. If the belt teeth are cracked or damaged, check if either camshaft is locked.
3. If there is noticeable wear or cracks on the belt face, check if there are nicks on the side of the idler pulley lock and water pump.

4. If there is wear or damage to only one side of the belt, check the belt guide and the alignment of each pulley.
5. If there is noticeable wear on the belt teeth:
   • Check the timing cover for damage.
   • Check that the gasket has been installed correctly.
   • Check for foreign object on the pulley teeth.

   If there is any trouble in the belt condition, replace the timing belt.

1. Remove any oil or water on the pulleys, and keep them clean.
   NOTE:

   • If there is a trace of water and/or oil on the timing belt, repair the leakage and install a new timing belt.
   • Wipe only the pulleys; do not use any cleaning agent.
2. Inspect the idler pulleys.
   1. Check that the idler pulley turns smoothly.
   2. Visually check the seal portion of the idler pulley for oil leakage.
3. Inspect the water pump.
   1. Turn the pulley, and check that the water pump bearing moves smoothly and does not make any noise.
   2. Visually check the drain hole for coolant leakage.
4. Temporarily install the crankshaft pulley bolt and washer to the crankshaft.
5. Turn the crankshaft counterclockwise by approximately 60°.
   NOTE: To prevent contacting the piston head and the valve head, set the crankshaft pulley at 60° BTDC/compression position.

6. Using SST, turn the timing pulleys, and align the timing marks of the timing pulleys with the No.3 timing belt cover.

   SST 09960-10010 (09962-01000, 09963-01000) 

   NOTE: Be sure to hold the SST with the timing marks aligned to prevent the left bank pulley from deviating to the right.

8. Face the front mark on the timing belt forward.
9. Align the installation mark on the timing belt with the timing mark of the crankshaft timing pulley.
10. Align the installation marks on the timing belt with the timing marks of the camshaft timing pulleys.

    NOTE: Be sure to hold the SST with the timing marks aligned to prevent the left bank pulley from deviating to the right.

1. Set the timing belt tensioner upright on the press.
2. Slowly press in the push rod.
   NOTE: Do not apply pressure more than 9.8 kN (1,000 kgf, 2,205 lbf) to the rod.
3. Align the holes of the push rod and housing, and pass a 1.5 mm hexagon wrench through the holes to keep the setting position of the push rod.
4. Release the press.

5. Temporarily install the tensioner with the 2 bolts. Alternately tighten the 2 bolts.

   Torque: 27 N*m (280 kgf*cm, 20 ft.*lbf) 

   NOTE: Be sure to tighten the bolts equally. Installing the tensioner at an angle may cause improper operation.
6. Remove the 1.5 mm hexagon wrench from the tensioner.
7. Turn the crankshaft 2 revolutions slowly and align the timing mark of the crankshaft timing pulley with the oil pump body.
   NOTE: Always turn the crankshaft clockwise.
