Re: T18/Dana300 swap update
Ok, Here's my thoughtprocess. The flywheel is a flat disk (in that CJ) so when I have a correct working clutch then it should work. correct ? I can imagine the linkage doesn't have enough throw and when the wrong clutch is used it doesn't go to the point of "maximum release" But I already messed with that, changing the linkage so it has more throw. But still it does the same thing. I am just wondering if the place where I got the clutch I have now maybe gave me a clutch that was wrong and that maybe the clutchdisk is too "thick" for the pressure plate used ? Anyway, I am going to take the Jeep apart (again). What I am wondering though ..... when I put a new clutch in and again it isn't working .... can I return it and say "this one isn't working for the application I told you I needed it for.

Did you check prices for the same part # at Summit Racing? Caveat: Although Summit might be less, due to the difficulty you are having in diagnosing your problem, you might be better off buying your parts locally, even if a few $ more, so you can take advantage of your supplier's expertise. (As a matter of principle, I am opposed to soliciting free advice from local merchants/repair experts and taking their time, only to buy "cheap" somewhere else.) As for returning the clutch after install - only if your parts man will take it back on "warranty" and label it "defective" so he can get a credit from his supplier. If your are going to pull the clutch one more time - set the clutch assembly you remove on a workbench next to one spec'ed for a '79 with T150 tranny and look to see if they are the same "height" off the bench. If the height is different, or there are any other visible differences, install the unit for a '79. If they are the same, you have a different problem and you may want to return the unused clutch. It is possible, although unlikely that you have a bent or warped clutch fork. When that was suggested to me, I looked at 5 or 6 used ones and although none appeared to be "bent," none of them exactly matched any of the others making it impossible to know which was warped, if any, or whether any/all/none were outside specs. If you suspect a warped fork, see if you can compare yours to a new fork. Finally, did you have your flywheel resurfaced? If not, take it to the machine shop and have it done.

Oh I don't even mind paying the guy that looked at my clutch labour and a tip and buy the new clutch from him IF it is going to work. I don't even mind buying the brand he likes, even if it is a different style (diafragm instead of the 3 finger type). If it is going to work I am wulling to spend a few extra $$$. (the swap was already expensive enough, so you probably see my point.

Ask for a clutch for a '79 CJ-7 with T-150 transmission. Since there were both V-8 and inline 6 engines in '79, you might want to confirm that the clutch part numbers are the same for both engines. My recollection is that they are the same. If you ask for what you actually have (258/T-150 Bellhousing and T-18 tranny), the parts guy won't have a clue what you are talking about because there are no such animals in his parts book. >do you mean the overall height ? yes.
