[TR] TR6 HVDA transmission conversion throw out bearing

[Bob Danielson]

I thought the original T/O bearing was from McLeod which worked great early 
on but over time their QA went down hill and the recent ones were failing. I 
got one of the last McLeod T/O bearings and it failed right out of the box 
during testing while the car was still on jack stands. Herman was in the 
process of testing in his own car a new T/O bearing from Quarter Master so 
he sent me one to test along with him. It did require a different Pressure 
Plate as the QM unit is flat faced and therefore needs a bent finger 
pressure plate. I've had 3 full driving seasons with it and not a drop of 
fluid has been added.

If you check out this page, it will show the difference between the two 
bearings & pressure plates:

This page gives you a good look at the QM unit:

The early Herman van den Akker HVDA transmission conversions used a Howe
hydraulic throw out bearing that was prone to failure in highway vehicles
(Howe indicates they are for racing and not highway use). Does anyone know
what the later version HVDA transmission conversions use for a hydraulic
throw out bearing?
Thanks in advance.
