Part 1

Removal

1. Disconnect the battery negative cable (A).
2. Remove the engine cover (B).




3. Remove RH front wheel.
4. Remove RH side cover.
5. Set No.1 cylinder to TDC/compression.




6. Drain the engine oil, and then set a jack to the oil pan.

NOTE:
Place wooden block between the jack and engine oil pan.

7. Disconnect the ground line and then remove the engine mounting bracket (A).




8. Remove the drive belt (A).




9. Remove the idler (A) and drive belt tensioner (B).





CAUTION:
Tensioner pulley bolt is left - handed screw.

10. Remove the water pump pulley (A), crankshaft pulley (B) and engine support bracket (C).





NOTE:
There are two methods to hold the ring gear when installing or removing the crankshaft damper pulley.
- Install the SST (09231-3K000) to hold the ring gear after removing the starter.




- Install the SST (09231-3D100) to hold the ring gear after removing the dust cover.
1. Remove the dust cover (A) on the bottom of the ladder frame and unfasten the two transaxle mounting bolts (B).




2. Adjust the length of the holder nuts (A) so that the front plate of the holder (B) puts in the ring gear (C) teeth.
3. Adjust the angle of the links (D) so that the two transaxle mounting bolts can be fastened to the original mounted holes.




4. Install the SST (09231-3D100) using the two transaxle mounting bolts and spacers. Tighten the bolts and nuts of the holder and links securely.





11. Disconnect the ignition coil connectors (A) and remove the ignition coils.




12. Remove the cylinder head cover (A).




13. Remove the compressor lower bolts.




14. Remove the compressor bracket.
15. Remove the oil pan.

CAUTION:
Be careful not to damage the contact surfaces of cylinder block and oil pan.

16. Remove the timing chain cover (A) by gently prying the portions between the cylinder head and cylinder block.





CAUTION:
Be careful not to damage the contact surfaces of cylinder block, cylinder head and timing chain cover.

17. The key of crankshaft should be aligned with the mating face of main bearing cap. As a result of this, the piston of No.1 cylinder is placed at the top dead center on compression stroke.

NOTE:
Before removing the timing chain, mark the timing chain with an identification based on the location of the sprocket because the identification mark on the chain for TDC (Top Dead Center) can be erased.

18. Install a set pin after compressing the timing chain tensioner.




19. Remove the timing chain tensioner (A) and timing chain tensioner arm (B).

[Single CVVT]





[Dual CVVT]




20. Remove the timing chain.
21. Remove the timing chain guide (A).

[Single CVVT]





[Dual CVVT]




22. Remove the timing chain oil jet (A).
23. Remove the crankshaft chain sprocket (B).




24. Remove the oil pump chain.


Inspection

Sprockets, Chain Tensioner, Chain Guide, Chain Tensioner Arm
1. Check the camshaft sprocket and crankshaft sprocket for abnormal wear, cracks, or damage. Replace as necessary.
2. Inspect the tensioner arm and chain guide for abnormal wear, cracks, or damage.
Replace as necessary.
3. Check that the tensioner piston moves smoothly when the ratchet pawl is released with thin rod.

Drive belt, Idler, Pulley
1. Check the idler for excessive oil leakage, abnormal rotation or vibration. Replace if necessary.
2. Check belt for maintenance and abnormal wear of V-ribbed part. Replace if necessary.
3. Check the pulleys for vibration in rotation, oil or dust deposit of V-ribbed part. Replace if necessary.
