Timing Chain: Service and Repair
TIMING CHAIN REMOVAL/INSTALLATION [LF]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 injures or death and damage. Fuel can also irritate skin and eyes. To prevent this, always complete the Fuel Line Safety Procedure.

16. Start the engine and:
^ Verify the ignition timing, idle speed and idle mixture.
17. Perform a road test.
Crankshaft Pulley Lock Bolt Removal Note
1. Remove the cylinder block lower blind plug.
2. Install the SST.
3. Turn the crankshaft clockwise until the crankshaft is in the No.1 cylinder TDC position (until the balance weight contacts the SST).
4. Hold the crankshaft pulley by using the SSTs.
5. Remove the crankshaft pulley lock bolt.
Front Oil Seal Removal Note
1. Remove the oil seal using a screwdriver as shown.
Chain Tensioner Removal Note
1. Using a thin screwdriver, hold the chain tensioner ratchet lock mechanism away from the ratchet stem.
2. Slowly compress the tensioner piston.
3. Hold the tensioner piston using a 1.5 mm (0.059 inch) wire or paper clip.
Oil Pump Sprocket Removal Note
1. Hold the oil pump sprocket by using the SST.
Oil Pump Sprocket Installation Note,
1. Hold the oil pump sprocket by using the SST.
Timing Chain Installation Note
1. Install the SST to the camshaft as shown.
2. Install the timing chain.
3. Remove the retaining wire or paper clip from the chain tensioner to apply tension to the timing chain.
Engine Front Cover Installation Note
Note: Install the front oil seal before performing the following procedure.
1. Apply silicone sealant to the engine front cover as shown.
Caution:
^ Install the engine front cover within 10 minutes of applying the silicone sealant.
^ Silicone sealant is not need in area C as indicated below due to an existing.
Thickness
A: 2.0 - 3.0 mm (0.079 - 0.118 inch)
B: 1.5 - 2.5 mm (0.059 - 0.098 inch)
2. Install the engine front cover bolts in the order as shown.
Front Oil Seal Installation Note
1. Apply clean engine oil to a new oil seal.
2. Push the front oil seal in the engine front cover by hand.
3. Compress the oil seal using the SET and a hammer.
Front oil seal press-in amount 0 - 1.0 mm (0 - 0.039 inch)
Crankshaft Pulley Lock Bolt Installation Note
1. Install the SST to the camshaft as shown.
2. Verify that cylinder No. 1 is at TDC of the compression stroke. (Crankshaft balance weight contacts SST.)
3. To position the crankshaft pulley, temporarily tighten it and, using a suitable bolt (M6 X 1.0 length 25 mm - 35 mm (0.99 - 1.37 inch)), fix the crankshaft pulley to the engine front cover.
4. Install the SSTs to the crankshaft pulley, lock the crankshaft against rotation.
5. Tighten the crankshaft pulley lock bolt using the following two steps.
1. Tighten to 96 - 104 Nm (9.8 - 10.6 kgf-m, 70.9 - 76.7 ft. lbs.)
2. Tighten 87°-93°
6. Remove the M6 x 1.0 bolt.
7. Remove the SST from the camshaft.
8. Remove the SST from the cylinder block lower blind plug.
9. Remove the SST from the crankshaft pulley.
10. Rotate the crankshaft clockwise two turns until the TDC position.
^ If not aligned, loosen the crankshaft pulley lock bolt and repeat from Step 1.
11. Install the cylinder block lower blind plug.
Tightening torque: 18 - 22 Nm (1.9 - 2.2 kgf-m, 13.3 - 16.2 ft. lbs.)
Cylinder Head Cover Installation Note
1. Apply silicone sealant to the mating surfaces as shown.
Caution: Install the cylinder head cover within 10 minutes of applying the silicone sealant.
Thickness: 4.0 - 6.0 mm (0.16 - 0.23 inch)
2. Install the cylinder head cover with a new gasket.
3. Tighten the bolts in the order shown.
Tightening torque: 8.0 - 10.5 Nm (81.6 - 107.1 kgf-cm, 70.8 - 92.9 inch lbs.)
