Good point Ken, the slave needs to be in good condition.
It is an option but a new long throw slave is definitely a preferable way to go, over a stock slave.

Scott,
I asked the forum about using a 7/8 MC, and at least one response was to be careful about exceeding the stroke of the stock
slave. I haven't checked, but if the longer stroke resulting from the larger dia MC does not get out of the smooth bore, it seems
like an alternative to a smaller bore (i.e., longer stroke) slave to increase clutch disengagement.

I never said to use a 7/8 inch master with a long throw slave. I would NOT do that.
What I said, (or meant), was you could use a 7/8 master with a stock slave to achieve a long throw installation.
Just another option...

Boyd,
I would call Dennis Quella and ask for his solution to your problem. (303) 660-6094. Tell Becky I sent you. :-)
My 2511 came from Dennis with a CNC 5/8" clutch master and an internal hydraulic throwout bearing.
At that time, the CNC bolt pattern required an aluminum adapter piece which Dennis supplied.
I would assume that adapter was sourced from Dennis' regular supplier - IPSCO, Mark Johnson (303) 252-4481
The Dennis sourced master was all aluminum, no SS or brass sleeve. I had rebuilt it once before, but with its obvious second failure
approaching, I looked for a better option than another rebuild.
I talked with Dennis and the very knowledgeable lady that picks up the phone at CNC.
I learned CNC now makes a proper bolt pattern clutch master for the Pantera. However, it is only sold through Dennis.
But as I already had the adapter, I could again use a new CNC master with their standard bolt pattern.
CNC offers most (all?) of their masters with a SS sleeve, but the SS is an upgrade option.
I ordered a standard (NOT Pantera bolt pattern) SS sleeved master, and on Dennis' advice changed to a bore of 3/4".
Part # 701-3/4-SS -- round CNC master with SS sleeve.
So, yes you can get a SS CNC clutch master. You can get a bolt-on from Dennis, just make sure it is the SS version.
Or you can source the adapter and use one of CNC's off-the-shelf SS versions.
As for Scott's suggestion of moving to a 7/8" version, I'd check with Dennis if that is advisable when used with your long-throw
slave.
Hope this helps.
Larry
