QuarterMaster Twin Disk Issues/Concerns

[Vanish70]

Hey everyone. I tried searching this topic, but couldn't find any information that was pertinent.

I have a 1g AWD and I'm currently using a QuarterMaster Twin Disk on it. I'm not using a different slave cylinder or a pedal stop. Currently there is a bit of freeplay at the top of my pedal, but not a lot. My main question is, what is the proper adjusting procedure for a clutch like this? I want to make sure I'm not overextending the clutch fingers. Also, how necessary is it to run a pedal stop or a different slave? I know lots of people who use these clutches on the stock components and seem to have good luck.

I want to make sure I do everything right because I'm about to install a built TRE trans and don't want to grenade anything because I didn't set up the clutch properly. Any advice, hints, or tips would be greatly appreciated.

Thanks!

Sent a PM to twicks69. He has the PTT/Quartermater twin disc clutch kit on his car and has more info about them than most of the people on this site.

Did you ever figure it out??

There might end up being a bit of slack at the top of the pedal (not actual free play, but little pressure to push before the actual pressure of the clutch), but that is usually a circumstance more in line with a leaking master cylinder seal that would cause pedal pump up.

If it was pedal pump up, it would have varying pedal feel depending on the clutch hydraulic temperatures or from air in the line.

If it was just a simple clutch master cylinder rod adjustment for proper clutch adjustment, then adjust it like any other clutch. First off, spin the rod totally out away from the firewall/toward the pedal assembly, and then bleed the clutch. Then, adjust the master cylinder rod towards the firewall until you get the proper pedal feel and engagement while being able to completely disengage the clutch when the pedal is fully depressed.

It takes a little bit of time, but it is easy enough to do.

If you overextend the clutch cover springs, you WILL HEAR IT! It will be a mean screaching noise -- you don't want that.... If you only do it for one or two times of pushing the clutch pedal down while checking engagement characteristics, it won't blow anything up. I would suggest just checking at idle, there is no reason to check if it is over-extended at any rpm higher than idle. To check if it is fully disengaging, then you can rev it up and see if the car is moving whatsoever.

Good luck,
