Thanks Dave, that is all I need. I assume the measurements are imperial?. Looking to alter my cushion drive so if I can use the same dimensions, replacements are easily available. Just have to get away from CNC as have sold too many kidneys already. Neil.

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.
