Drivers

It's been so long since I pressed a set on a drive shaft I can't remember.
Do you mount em so the extros are centered in the window or do you favor the inside of the window so the track doesn't wonder around?

I try to make sure the track drive lugs are running true to sprockets and find the windows take care of themselves. Some drivers don't have the built in "wheels" so they rely on extroverts for centering track. On that style (Cat) I try to favour the inside of track window to keep it centered.

A general rule of thumb is 8'' between inside edges/surfaces of extroverts. Pro Tip... we usually install to the lesser side of 8'' somewhere in the neighborhood of 7.875". Like previously mentioned the extroverts will keep the track from wandering so if there very close to the inside edges of the track windows it will eliminate a lot the wandering.
