    For reference here are a few pictures that show what a longer ball stud will do to the clutch fork position.

    I'm going with the longer pivot stud. Right now the TO bearing goes all the way to the preasure plate but not enough the disengage the clutch. So it's just a bit more to work. Thanks all for your help. Plus it's a much cheaper option than a new bearing. Im going to search around town and see if I can find a longer one locally before I order from an online source. I like to support local businesses!!

    You stated the clutch was slipping badly when you got the Jeep. Were you able to get it to disengage at that time?

    Yes I was but barely. That clutch disk may have been slightly thicker allowing some friction. That's the only thing we could come up with. We inspected the bearing movement and it's all working as it should. Just need a bit more. We think a longer stud should give us what we need. It kills me because Sunday is supposed to be absolutely gorgeous and would have really liked to get out in it. Oh well,so it goes!!

    Alright gents. Here's my issue. This is my clutch fork stud. Very different than the ones I've seen and you guys have shown. Can't find a longer one. Guess I'll have to spend the money and buy an adjustable throw out bearing. Oh well

    Having a serious issue installing this new Sacks clutch kit. Any and all help would be great!!!! Here's what's up....when the throw out bearing pushes the little spring fingers,on the old clutch there was almost an inch and a half distance between the fingers and the friction disk. On the new clutch kit (Sacks) there is only about a half in. So there isn't enough play to disengage the clutch. The new friction disk is Much thicker where the springs are than the old. I'm pretty sure the engine is a 71 from the casting numbers. 225 v6. And I'm also pretty sure the trans and transfer are to that motor. I think the trans is a Dana 86 and I know the transfer is a Dana 18. I'm lost as to how I can find a right friction disc. The disc is a 10 1/2 inch clutch. Thanks for any help!!!!

    I could be off base here but couldn't you shim that with washers for a higher standoff?

    Yes! I have that issue figured out. Now my issue is the TO bearing pushing the PP finger springs into the friction disk. At a loss!!

    Back to the question of whether or not the right side of the disc is facing the flywheel?

    Yeah, but he answered with an if so I'm throwing that out again. Something strange is going on since his old clutch didn't work right either.

    Pictures would be very helpful in solving this..........I'm having a hard time comprehending what you mean when you say you first had an 1.5" between the friction disk and fingers? And likewise now with the Sacks clutch having only .500" and then you saying "there isn't enough play to disengage the clutch".............throw-out bearing travel is what disengages the clutch disc from the flywheel and pressure plate , and on a standard pressure plate .400-.600" of travel is all you need to disengage the clutch............Pictures of everything you have would really be helpful.

    Something is definitely screwy here. Adding it all up, clutch didn't work correctly when he got it, knowledgeable instructor supervising installation, still doesn't work right after new install? Sure sounds like something is mismatched.

    He's thinking something is mismatched also. Now he's doing his homework to see what exactly everything is. We are thinking Jeep T18 trans. Just very frustrating because I wanna drive my jeep.

    The Jeep is registered as a 66 but when I looked up the engine casting it says it's a 71. Also the engine is red/orange with a dry filiment air filter. Looks original with factory stickers but who knows. Every dauntless I've seen is green with oil bath filter. So who know what came from where.

    Good reference. I am questioning this on my rig as well. I have a 198 and the pedal has to almost hit the floor to disengage the clutch. It doesnt slip so dont think its worn. I am trying to undertand what a longer or shorter stud will do to the clutch travel. Would this solve my issue and bring the pedal up more or make it worse?

    I have already replaced linkage, cross shaft, pedal bushing hardware, etc. I know the 198 is not a "Jeep" motor but many had them in the day as a tinkering.... Thoughts as i image is the same principal?
