Installing

NOTE:

Because of the small clearance between the balance shaft and cylinder block, the balance shaft may need to be cooled in order to install it. Check if the balance shaft can be inserted into the cylinder block without forcing it in. If this is not the case, then the balance shaft must be installed cooled.

For the correct tightening specifications, refer to BALANCE SHAFT TIMING CHAIN OVERVIEW .

-- Check the installation position of the pipe for the balance shaft -arrow-.
