I have changed from a single disk clutch to a triple disk ram 6 1/2. Upon intitial install the pedel felt strong but wouldn't disengage the clutch enough to get the trans in gear. Even though there was plenty of movement in the pull slave and fork at the slave end I think we have a geometry issue. I was looking at using the adjustable pivot ball from lakewood to correct this. Is this a practical solution to correcting the goemetry? Is the total adjustment eough when using the lakewood bell sufficient? We are looking for a solution other than buying a internal slave. We have plans to change the entire driveline this coming off season so spending large amount's of money doesn't make cent's.

Main thing there is to make sure the throw out bearing is contacting the clutch fingers evenly............that's why they make the adjustable balls.. If not you have to use a longer throw out bearing, shorter ball, adjustments adjustments adjustments....I hate fooling with clutches I haven't dealt with before............something always happens. Make sure you don't over extend the fingers..........put a stop on the thing when it releases or make it release down next to the floor.

Ram say's the stack hieght as measured from the crank is a lot smaller in the triple disk(I knew that already) and I probably just need the long GM version or the adjustable one from lakewood and like company's. I may still need a longer throwout bearing though. I'm waiting for part's to come in.

I had to go to the public libary and look up the correct part. I am listing them here for future referance to anyone. According to my search earlier there's not much info. Use either one of these part's:

PN: GMC3729000 13/16 x 16t x 1.48" overall length.

PN: GMC3790556 13/16 x 16t x 1.78" overall length.

The longer one worked better for me but overcentering was a problem solved with a pedel stop. They can also be found on 84-87 chevy astro van with the 4.3 fo you salvage yard minded.
