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 planning to reuse the belt, check the installation marks on the timing belt.
1. Check that there are 3 installation marks on the belt by turning the crankshaft as shown in the illustration.
If the installation marks have disappeared, place new installation marks on the 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 are aligned.
If not, turn the crankshaft 1 revolution (360°).





3. Using the crankshaft damper bolt, turn the crankshaft counterclockwise by approximately 45°.

NOTICE: With timing belt disengaged: The crankshaft damper must be at the correct angle to avoid damage in later steps. If the crankshaft pulley is at the wrong angle and then the camshaft timing pulley and the camshaft are removed, the piston head and valve head may come in contact and be damaged.

c. Alternately loosen the 2 bolts. Then remove the 2 bolts, 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 belt from the timing belt idler No. 1, and remove the belt.

INSTALL TIMING BELT
a. Check the 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 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, oil pump pulley, water pump pulley, idler No. 1 and No. 2. Keep them clean.

NOTICE: Only wipe the pulleys. Do not use any cleansing agents on the pulleys.





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: Turn the camshaft timing pulleys slightly clockwise to make installation of the timing belt easier.

Camshaft timing pulley of LH bank: 1/2 of a tooth
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.





3. Remove any oil or water on each pulley. Keep them clean.

NOTICE: Only wipe the pulleys. Do not use cleaning agents on the pulleys.

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





e. Set the belt tensioner.
1. Using a press, slowly press in the push rod using 981 to 9,807 N (100 to 1,000 kgf, 220 to 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.





f. Install the belt tensioner.
1. Temporarily install the belt tensioner with the 2 bolts.
2. Alternately tighten the 2 bolts.
Torque: 26 Nm (265 kgf-cm, 19 ft. lbs.)
3. Using pliers, remove the 1.27 mm hexagon wrench from the belt tensioner.





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

NOTICE: Always turn the crankshaft pulley clockwise.





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