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". Before Service Precaution

Tightening torque
- 20-30 Nm {2.1-3.0 kgf-m, 14.8-22.1 ft-lbf}
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 before the applied silicone sealant starts to harden.
- Completely remove any oil, dirt, sealant, or other foreign matter adhering to the engine front cover and engine front cover installation surface. If any oil, dirt, sealant, or other foreign matter is not removed from the space between the engine front cover and engine front cover installation surface, it may cause a sealing malfunction.
Thickness
- A: 2.2-3.2 mm {0.087-0.12 in}
- B: 1.5-2.5 mm {0.06-0.098 in}
- C: 2.2-4.3 mm {0.087-0.16 in}
- D: 3.3-4.3 mm {0.13-0.16 in}
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 SST and a hammer.
Front oil seal press-in amount
- 0-1.0 mm {0-0.039 in}
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 length25 mm-35 mm {0.99 in-1.37 in}), 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.
a. Tighten to 96-104 Nm {9.8-10.6 kgf-m, 70.9-76.7 ft-lbf}
b. 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-lbf}
Cylinder Head Cover Installation Note
1. Apply silicone sealant to the mating surfaces as shown.
CAUTION:
- Install the cylinder head cover before the applied silicone sealant starts to harden.
Thickness:
- 4.0-6.0 mm {0.16-0.23 in}
2. Install the cylinder head cover with a new gasket.
3. Tighten the bolts in the order shown.
