[Fot] Tilton vs Stock Clutch (Was Clutch question)

[Joe Boruch]

The set up that came with my car had 2 throw-out bearing bushings brazed
together to reduce the travel to make up for the much shorter quartermaster
clutch.  To keep from over extending the pressure plate there was an
adjustable stop on the clutch pedal.  I have since changed to a Howe hydraulic
release bearing, but still use an adjustable stop to keep from over extending
the pressure plate.  Joe(B)

Bill, a related question on stock vs. Tilton;
I"m fitting an aluminum flywheel, 7 1/4 tilton single plate.

>From my collection; I have a couple collars for release bearings,
that are different lengths, in what look like PO modifications to
deal with the different standoff distance off rear of the block given
modified flywheel/pressure plates.

With a tilton setup, how do you control the throw such that you don't
over-extend the diaphram spring?  Do the hydraulics take up the
slack, do you have to use a different collar to control the throw
distance, or do you have put a hard stop for the lever arm?

After installing the tilton, and a longer collar, I have about 3/8"
play between fully retracted and when the release bearing first touch
the tilton diaphragm spring.

What else should I look for?  I unfortunately didn't measure the
lightened stock steel flywheel & stock clutch setup standoff distance
prior to this change.

Thanks

I've tried a lot of different clutches, including modified stockers,
Tilton, etc., and I like the Quartermaster clutches best. 7.25 two
