3. Install in the reverse order of removal.

Scheme 74

Scheme 75

1. Remove the drive belt. (Refer to " DRIVE BELT ")
2. Remove the alternator. (Refer to " ALTERNATOR ")

Scheme 81

Scheme 82

1. Remove the drive belt. (Refer to " DRIVE BELT ")
2. Remove the engine room under cover.
3. Remove the passenger side front tire.
4. Remove the crankshaft damper pulley (A). Tightening torque: (47.0 ~ 50.9 N.m) + (38°~ 42°) [(4.8 ~ 5.2 kgf.m) + (38°~ 42°), (34.7 ~ 37.6 lb-ft) + (38°~ 42°)] NOTE: There are two methods to hold the ring gear when installing or removing the crankshaft damper pulley. Install the SST (09231-2B100) to hold the ring gear after removing the starter. Install the SST (09231-3D100) to hold the ring gear after removing the dust cover. Remove the bracket (A). Remove the dust cover (A) and unfasten the transaxle mounting bolt (B). Adjust the length of the holder nuts (A) so that the front plate of the holder (B) puts in the ring gear (C) teeth. Adjust the angle of the links (D), and fasten the bolt 70 mm (2.7559 in) in the original mounted hole. Tighten the bolts and nuts of the holder and links securely.
5. When installing the pulley, the groove on the pulley should be positioned outside.

Scheme 83

Scheme 84

1. Crankshaft damper pulley. (Refer to " DAMPER PULLEY ")
2. Remove the front oil seal. NOTE: Using the SST (09455-21200), reassemble the timing chain cover oil seal.
3. Install in the reverse order of removal.

Sprockets, Hydraulic Tensioner, Chain Guide, Tensioner Arm, Timing Chain

1. Check the CVVT sprocket, crankshaft sprocket teeth for abnormal wear, cracks or damage. Replace if necessary.
2. Check a contact surface of the chain tensioner arm and guide for abnormal wear, cracks or damage. Replace if necessary.
3. Check the hydraulic tensioner for its piston stroke and ratchet operation. Replace if necessary.
4. Check the timing chain for its elongation, abnormal wear or damage. Replace if necessary.
