    Has anyone had problems with their linkage binding or not engaging the clutch during Hi Tweakage type times?Whenever I get all crossed up and about to crawl over the next obstacle my clutch wont grab enough to allow for forward movement?I dont git it! I cant see haw theres much adjustment to this system either so what do I do?

    Mine does the same thing. I should have used hydrolics on the clutch instead of a manual one.Between the body flex and frame flex i have gotten stuck in some odd places because the clutch didnt work . i have even had the clutch rod slip off the fork before.

    The only way to fix it is to go hydraulic.

    I am too am trying to go with hydrolic. I posted a question on the 69-72 board and got a few answers. If you guys have any input on how you have done it and the parts you used, let us know.

    thanks,

    That's done to a stock clutch fork that had mechanical clutch. That's a SM420 tranny in a internet buds jeep. The Slave is a pull type. You don't get into the oil filter clearence issues. Willwood also sels a clutch master that with some creativity you can make work on the fire wall.

    My linkage occasionally binds up. One time, my clutch bound up at Mudstock in Potosi, Mo. I was at the Urban Rockcrawling Course and had drove the K5 up the front of a School Bus. I stopped just as the front tires reached the roof - to take photos. When I tried to disengage the clutch, it would not release. The truck kept going! Had to kill it, then get pulled off the Bus by another truck. My clutch was smoking the whole way as I was being strapped backwards. We finally got me down from the School Bus, then I tried a concrete culvert and had similar results. It was so bound up, I could not get it into neutral! Finally Bigdaddyof2 gave it a yank and it went into neutral. I didn't try any more that day! Found out the problem wasnt linkage, it was the pressure plate collapsed. So, pick up your latest issue of 4 Wheel Drive and Sport Utility magazine and look at the Mudstock coverage. There is a photo of a Jeep climbing the same Bus. Well, if my clutch hadnt failed, you would have been looking at my K5 on that Bus! The camera man was there watching, but never snapped a pic! Ill post photos sometime soon. Anyway, thats my story and I'm stickin' to it!

    Anyone heard anything about the hydraulic throw out bearings? I would think that would be about the EASIEST way to go, yet I'm not sure if anyone here has gone that route yet.

    Yeah Jeep has tried it and they fail all the time. To much heat in there it bakes the seals out of them. Then the fluid trashes the clutch. Seen one catch on fire this way. It was leaking but still working guy slipped the clutch enough to ignight the fluid.

    I've had a little bit of bind in my linkage at times also. I think that Mcleod sells a hydralic throw out bearing setup but it cost a lot. Summit sells a hydralic cylinder that is a pull type that can be mounted to the trans. You have to figure out how to mount and work the slave cyclinder though. The last option for me was to go to an automatic. My wife won't even try to drive my 465 so I'll be selling it soon. Good luck.

    I'm sorry but that image is funny...burning clutch! Would be horrible, but yet that image : )

    Glad I got hydraulic already I guess, but I can't imagine myself crossing the truck enough to mess up the linkage. But thats pretty light duty off roading.
