Repair Procedures

Removal

1. Remove the timing chain.


NOTE:

2. Install a set pin after compressing the balance shaft chain tensioner.
3. Remove the balance shaft chain hydraulic tensioner (A).
4. Remove the balance shaft chain tensioner arm (B).
5. Remove the balance shaft chain guide (C).




6. Remove the oil pump & balance shaft module (A) and balance shaft chain (B).





CAUTION:
Do not disassemble the oil pump & balance shaft module.

Installation

1. 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.
2. Confirm the balance shaft module timing mark.
Timing marks to be visually aligned with centers of adjacent cast timing notches.




3. Install balance shaft module that the timing mark of balance shaft module sprocket should be matched with the timing mark (color link) of balance shaft chain.
