Are you changing this because there is an issue or just because you have reached 100,000 miles?
The balance shaft chain is not mentioned in any of the tables so due to its absence, I would say it does not need to be changed unless there is an issue. However, if you are there, then it may not hurt to change it as well. Clearly you are not going to hurt anything.
