Timing Component Alignment Marks: Locations

CAUTION: Incorrect removal or installation of the timing belt can result in damage to internal engine components.

For complete Timing Belt Removal and Installation information, please refer to Timing Belt; Service and Repair. Service and Repair

REMOVE TIMING BELT





a. If re-using the timing belt, check the installation marks on the timing belt.
1. Check that there are 3 installation marks on the timing belt by turning the crankshaft as shown in the illustration.
If the installation marks have disappeared, place a new installation mark on the timing belt before removing each part.
b. Set the No. 1 cylinder to approximately 50° BTDC/compression.





1. Using the crankshaft damper bolt, turn the crankshaft to align the timing marks of the crankshaft timing pulley and oil pump body.





2. Check that the timing marks of the camshaft timing pulleys and timing belt plates aligned.
If not, turn the crankshaft 1 revolution (360°).





3. Using the crankshaft damper bolt, turn the crankshaft counterclockwise by approximately 50°.

NOTICE: If the timing belt is disengaged, having the crankshaft pulley at the wrong angle can cause the piston head and valve head to come into contact with each other when you remove the camshaft timing pulley and camshaft, causing damage. So always set the crankshaft pulley at the correct angle.

c. Alternately loosen the 2 bolts, and remove them, the belt tensioner and dust boot.





d. Using SST, loosen the tension between the camshaft timing pulley (RH bank) and crankshaft timing pulley by slightly turning the camshaft timing pulley (RH bank) counterclockwise.
SST 09960-10010 (09962-01000, 09963-00350)
e. Disconnect the timing belt from the timing belt idler No.1, and remove the timing belt.

INSTALL TIMING BELT
a. Check the timing belt idler No. 1 and No. 2.
1. Visually check the seal portion of the idler pulley for oil leakage.
If leakage is found, replace the idler.
2. Check that the idler turns smoothly.
If necessary, replace the idler.





b. Check the water pump.
1. Visually check the air hole and water hole for coolant leakage. If leakage is found, replace the water pump and timing belt.
2. Turn the pulley, and check that the water pump bearing moves smoothly and quietly.
If necessary, replace the water pump.
c. Remove any oil or water on the crankshaft pulley, oil pump pulley, water pump pulley, idler No. 1 and idler No.2, and keep them clean.

NOTICE: Only wipe the pulleys; do not use any cleansing agent.





d. Set the No. 1 cylinder to TDC/compression.





1. Turn the hexagon wrench head portion of the camshaft to align the timing marks of the camshaft timing pulleys and timing belt plates aligned.

HINT: Setting positions of the camshaft timing pulleys by turning them slightly clockwise makes it easy to install the timing belt:
Camshaft timing pulley of LH bank: 1/2 teeth
Camshaft timing pulley of RH bank: 1 tooth





2. Using the crankshaft damper bolt, turn the crankshaft to align the timing marks of the crankshaft timing pulley and oil pump body.





e. Install the timing belt.
1. Remove any oil or water on the each pulley, and keep them clean.

NOTICE: Only wipe the pulleys; do not use any cleansing agent.

2. Face the front mark (arrow) on the timing belt forward.
3. Connect the timing belt to the crankshaft timing pulley. Align the installation mark on the timing belt with the timing mark of the crankshaft timing pulley.
4. Connect the timing belt to the idler No. 2.
5. Connect the timing belt to the camshaft timing pulley (LH bank).
- Align the installation mark on the timing belt with the timing mark of the camshaft timing pulley.
6. Connect the timing belt to the water pump pulley.
7. Connect the timing belt to the camshaft timing pulley (RH bank).
- Align the installation mark on the timing belt with the timing mark of the camshaft timing pulley.
8. Connect the timing belt to the idler No.1.





f. Set the belt tensioner.
1. Using a press, slowly press in the push rod using 981 - 9,807 N (100 - 1,000 kgf, 220 - 2,205 lbs.) of pressure.
2. Align the holes of the push rod and housing, pass a 1.27 mm hexagon wrench through the holes to keep the setting position of the push rod.
3. Release the press.
4. Install the dust boot to the belt tensioner.





g. Install the belt tensioner.
1. Temporarily install the belt tensioner with the 2 bolts.
2. Alternately tighten the 2 bolts
Torque: 26 Nm (270 kgf-cm, 19 ft. lbs.)
3. Using pliers, remove the 1.27 mm hexagon wrench from the belt tensioner.
h. Check the valve timing.

NOTICE: Always turn the crankshaft pulley clockwise.





1. Using the crankshaft damper bolt,slowly turn the crankshaft pulley 2 revolutions from TDC to TDC.





2. Check that each pulley aligns with the timing marks as shown in the illustration.
If the timing marks do not align, remove the timing belt and reinstall it.
3. Remove the crankshaft damper bolt.
