Timing Chain: Service and Repair
TIMING CHAIN REMOVAL/INSTALLATION [L3]Warning:
- Fuel vapor is hazardous. It can very easily ignite, causing serious injury and damage. Always keep sparks and flames away from fuel.
- Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious injuries or death and damage. Fuel can also irritate skin and eyes. To prevent this, always complete the "Fuel Line Safety Procedure".
1. Disconnect the negative battery cable.
2. Remove the plug hole plate.
3. Remove the dipstick.
4. Remove the spark plugs.
5. Remove the tire (RH).
6. Remove the under cover.
7. Loosen the water pump pulley bolt and removal the drive belt.
8. Remove the crankshaft position (CKP) sensor.
9. Drain the engine oil.
10. Remove the P/S oil pump with the oil hose still connected and position the P/S oil pump so that it is out of the way.
11. Remove the front drive shaft (RH) from the joint shaft.
12. Remove in the order indicated in the table.
13. Install in the reverse order of removal.
14. Start the engine and:
- Inspect for the engine oil, engine coolant, transaxle oil and fuel leakage.
- Verify the ignition timing, idle speed and idle mixture. (See ENGINE TUNE-UP [L3].) Testing and Inspection
15. Perform a road test.
Crankshaft Pulley Lock Bolt Removal Note
1. Remove the cylinder block lower blind plug.
2. Install the SST.
3. Rotate the crankshaft clockwise until the crankshaft is in the No. 1 cylinder TDC position (until the balance weight is contacting to the SST).
4. Hold the crankshaft pulley using the SSTs.
Chain Tensioner Removal Note
1. Hold the chain tensioner ratchet lock mechanism away from the ratchet stem using a thin screwdriver.
2. Slowly compress the tensioner piston.
3. Hold the tensioner piston using a 1.5 mm (0.059 in) wire or paper clip.
No.3 Engine Mount Rubber and No.3 Engine Joint Bracket Removal Note
1. Install the SST using the following procedure.
Caution:
- Refer to the SST instruction manual for the basic handing procedure.
(1) Install the right rear shaft of the SST to the bolt of the right shock absorber as shown in the figure.
(2) Install the left rear shaft of the SST to the bolt of the left shock absorber. (Identical position to the right side)
(3) Install the left/right front shaft of the SST with front foot No.2 to the bolt as shown in the figure.
* : If equipped.
(4) Adjust the positions of the SST side bars so that they are the same height (left and right) and horizontal.
(5) Make sure each joint is securely tightened.
2. Support the engine using the SST.
Note:
- The SST (49 E017 5AO) can be used in place of the SST (49 C017 5AO).
3. Remove the No.3 engine mount.
