Pinning gears on IMS?

Thanks for any input.

All right, I`ll pin it then. Any idea about how to check the gear alignment? Also, there`s a punch mark on the external side of the largest gear, looks like a timing mark, any idea what that is referring to?

Thanks!

No. We send our out to a shop that checks the gear indexing before pinning them. Never had a problem when they were done.
