    I installed a buick 350 into my 66 cj5. I had to use the bell housing from my 225. I also used to clutch fork from the 225. Now that I have installed my SM465 and Dana 300 I think I am having clutch problems. I have no drive shafts on yet, and the engine is not ready to be started, but when I finished installing every thing I put the tranny in gear and could not turn the yoke. In nuetral I could. then I engaged the clutch while in gear and could just barely turn the yoke with a LOT of effort. When I let the clutch out it was still about the same, turned but very very stiff. Any idea's? There is for sure pressure when I push the pedal. actually takes more effort than my 225 did. Thanks Guys. Zach Jachowicz

    I don't think you can tell a lot without the driveshaft in and actually running the engine. It should have a fair bit of resistance on the yoke with the clutch pedal pushed in and the tranny in gear. But remember, your hand can't generate 150 hp. Put the rear driveline in, block the tires, put it in gear and try to start it with the clutch pedal depressed. You should be able to tell if the clutch is releasing.

    With the trans in gear even with the clutch in it will have major resistance, because you're turning the transfer case gearing, plus all the tranmission gearing (because it's in gear) plus the input shaft and the clutch disc, which is probably rubbing against either the pressure plate or flywheel.

    Ok guys. Thanks. I will hook up my shafts this weekend (need to re-change my pinion angle) and when I get that engine going I will see what happens. What a relief. Happy wheeling guys and maybe I too can hit the trails once again sometime soon.

    Ok, So I hooked up the rear Drive shaft and jacked the rear axle off the ground to test this clutch out. Well When in gear I can still spin the wheels pretty easy, it does change a little by what gear I am in, but still spins no problem. I then I fired the engine up while in gear. The the jeep jumped off the jack and hit a tree! No not really. It did not turn the wheels even a little. I started to look a little closer through the side hole in my bell housing (for the clutch fork) and noticed a big problem. My throwout bearing was resting against my tranny. Right up against that bearing retainer on the tranny, which prevented it from ever realeasing pressure off of the pressure plate. Can I just get a different size bearing? I thought I may have put the wrong one on but when I tore it all apart and compared it to the one that was on my 225 it was the exact same size. Please help anyone that has an idea.

    I guess you're saying the throwout bearing assembly is too long and keeps the clutch disengaged?

    When you say the bearing was sitting up against the tranny, was it properly engaged in the clutch fork? Is the input shaft the proper length? Have you checked to see if you need an adapter housing instead of the one you have?
    With the tranny in neutral you should be able to turn the shaft. But the fact that it doesnt turn the shaft with the engine running and in gear says that there is no engagement. First I'd check the input shaft length like stated, then check the bearing clearance for movement.

    Monkeyman,
    GM engines and clutches use 6 different length throw-out bearing lengths.
    The low profile diaphram clutch uses longest--- and the three finger type clutches use the shortest. The clutch arm needs to be about 10 degrees forward from a right angle installed---- NOVAK Enterprises has a technical www page with more information. You have probally installed the wrong throw-out (clutch release) bearing for your clutch. If there is a clutch speciality shop near where you live--- ask around and you can find a GM freak who knows which throw-out bearing you need with your engine,cluch type and bell housing. This is a common problem, and is technically easy to fix---but you have to pull the bell off the engine to get the right throw-out bearing and collor.

    Good luck

    Yeah I for sure have a too long through out bearing. I will hold off on getting the right one till I get my centerforce clutch. I am going to buy a dual friction clutch for it. I figure may as well put it in now and say the hassle later. Anyone know the cheapest sorce for these clutches?
