Hello Neil,

Being a soft product (hard to measure) I am sending  Tracy’s metal bushing and coupling sizes instead. Both Tracy’s used and the group new replacement bushings have a friction slip fit on the metal parts. If you would like I can send 1 used Tracy supplied bushing and a set of the group replacement bushings, no charge.

Thanks,

Dave Williams

Bushing OD - .748

Bushing Height - .577

Coupling ID – 1.400

Coupling Height - .557

Tracy Used Bushing Durometer – 55

Group New Bushing Durometer – 70

Tracy’s used Bushing Height - .567

Group New Bushing Height - .572

Group,

                     Was asleep as usual but the group bought replacement rubber bushed for the tracy redrive.  Can anyone tell me the physical dimensions and what durometer they were?  Just looking at getting a similar product from Viton as viton handles much more heat.

Neil.
