Timing Belt: Service and Repair

TIMING BELT REMOVAL/INSTALLATION [KL]
1. Disconnect the negative battery cable.
2. Remove the crankshaft position sensor.
3. Remove the P/S oil pump with the pipe still connected.
4. Remove the spark plug.
5. Remove in the order indicated in the table.
6. Install in the reverse order of removal.
7. Verify the air gap. Refer to Powertrain Management.
8. Start the engine and
1. Inspect the pulleys and drive belt for runout and contact.
2. Verify the ignition timing.

Crankshaft Pulley Removal Note





- Hold the crankshaft by using the SST

Caution: The crankshaft position sensor rotor Is on the rear of the crankshaft pulley, and can be damaged easily.

No.3 Engine Mount Rubber Removal Note
1. Support the engine by using the chain block.
2. Remove the No.3 engine mount rubber.

No.1 Idler Removal Note
1. Install the crankshaft pulley bolt.





2. Turn the crankshaft clockwise and align the timing marks. (No. 1 piston is at TDC of the compression stroke.)

Caution: When removing the pulley bolt, hold the pulley so that the bolt holes are aligned, otherwise the threads can be damaged.





3. Remove the No.1 idler pulley.

Timing Belt Removal Note

Caution: When removing the bolt, hold the tensioner so that the bolt holes are aligned, otherwise the threads can be damaged.





- Loosen the auto tensioner bolts and remove the lower bolt.

Caution: Forcefully twisting the belt, turning it Inside out, bending it, or allowing oil or grease on it will damage the belt and shorten its life.





Note: Mark the timing belt rotation on the belt for proper reinstallation.


Timing Belt Auto Tensioner Installation Note





1. Measure the tensioner rod projection length. Replace the auto tensioner if necessary.
Projection (Free length)
Type A: 14.3 - 15.1 mm (0.563 - 0.594 inch)
Type B: 12.0 - 13.0 mm (0.473 - 0.511 inch)





Note: There are two types of tensioners and they are interchangeable.

2. Inspect the auto tensioner for oil leakage. Replace the auto tensioner as necessary.

Caution: Applying pressure of more than 9.8 kN (1,000 kgf, 2,200 lbs.) can damage the auto tensioner.





3. Slowly press in the tensioner rod by using a press.





4. Insert a pin into the hole in the body, as shown, to hold the tensioner rod.
Pin diameter: 1.4 mm (0.055 inch)

Timing Belt Installation Note

Note: This must be done to reduce the timing belt resistance when the idler pulley is installed.





1. Set the tensioner in place and hand tighten the tensioner upper bolt.





2. Turn the camshafts clockwise and align the timing marks.





3. Using the crankshaft pulley bolt, turn the crankshaft clockwise and align the timing marks.
4. With the No.1 idler pulley removed, install the timing belt on the pulleys in the order shown below.
a. Timing belt pulley
b. No.2 idler pulley
c. Camshaft pulley (LH)
d. Tensioner pulley
e. Camshaft pulley (RH)





5. Verify that there is tension between pulleys (3) and (1), and between pulleys (1) and (5).

Caution:
- Verify that the belt has no looseness at the tension side.
- Do not damage the bolt threads when installing.





6. Install the No. 1 idler while applying the pressure on the timing belt.





7. Push the auto tensioner in the direction of the arrow and hand tighten the lower bolt. Tighten the bolts.





8. Remove the pin from the auto tensioner to apply tension to the belt.
9. Turn the crankshaft clockwise twice, and align the timing marks.





10. Verify that all timing marks are correctly aligned. If not, remove the timing belt and repeat from Timing Belt Auto Tensioner Installation Note.

Crankshaft Pulley Installation Note





- Hold the crankshaft by using the SST.
