[Fot] TR6 Throwout bearing wanted

[David Gott]

Hi Scott,
My TR4 has a 1980’s Tilton 7.25” dual clutch setup, that turns out is really an AP racing clutch setup that they were reselling at the time.  AP still makes all the parts; seems to be similar to the Quartermaster 7.25 sintered clutches.   Try looking at AP racing release bearing options here, along with some engineering diagrams of some options for you:Release Mechanism and Bearings | AP Racing

I’m trying to switch from the aluminum flywheel/stock size clutch to a Quartermaster steel flywheel and 7.25” clutch.  The challenge is the throwout bearing - I’ve included photos of the current one I use and a new replacement I picked up.  The QM pressure plate needs something smaller in diameter than the new replacement.  If I could find one that’s more like what I have, it would work - ideally the contact surface is even closer to 2” in diameter.The photos below indicate that the profiles are different, and the profile of the old one results in a smaller contact diameter.

QM recommends a radiused contact surface.
Any thoughts on where to source one like the one I have?  I could convert to hydraulic, but would prefer not to as I’m guessing that’s not a simple bolt-in.
