What to do.......

[Raptor]

The balance shaft has the smaller oil pump gear on it's end bolted down while the other gear has the timing belt driven sprocket on it. They both require locktight and have different torque specs for each.
The balance shaft can come out with the timing belt gear still attatched and proper tension still being maintained. That is a good thing to hear anyway, at least there is no top end issues to worry about.
