Looking for tech help! I have a 78 Cj-7 with a 304, 3-speed tranny, To make a long story short, When shifting, It takes a few seconds for the clutch to fully engage. I have adjusted the linkage in hopes that it would help, without luck. Does this sound like I need a new clutch, or should I continue to crank down or back off on the adjusting nut?

give a little more to the story, like: how long has it been doing this? have you recently replaced the clutch? do you know if that stupid pivot ball is in the bellhousing?
that could help in properly diagnosing.

It has just really started to act up within the last 2 days. Today I got underneath after I posted this, and backed off the locking nut and adjusting nut. It seems to not be slipping as much after the slight adjustment and the motor feels like it has more power. Where as before the motor would be taching high and it seemed as if the power wasn't making it to the wheels. I really felt it when I shifted gears, Normally it would hook up pretty hard. Looking at the clutch, it seems fairly new, not sure how many miles it has on it. I just bought this jeep a few weeks ago.
How hard is it to change the clutch, will I have to pull the transmission and transfer case completely out down and away from the vehicle? Or, Can I just back it away from the motor and put on in like this?

It does sound like an out of adjustment deal as you have found, but I'm wondering what has caused this to happen over the passed couple of days???
Do small adjustments on it. Too much and you'll burn your clutch up, too little and you'll be grinding gears.
to replace the clutch, some like to pull the engine and tranny as one unit out the front. I prefer to drop the tranny and pull the clutch from underneath. the T-150 isn't too bad, but nice to have a friend to help balance it and the D20. (I'm a skinny bastard too.) Tranny Jacks help.
If you can get it adjusted and it seems to stay and grab fine, then I wouldn't worry about it right now. if you adjust and continue to have issues,you may want to think about pulling things apart to find out why.

Check your clutch linkage to make sure it isn't worn out giving you a 'misadjustment' (getting stuck in a worn out spot). I had the original (at least it looked that way) Borg & Beck type 3 finger pressure plate/clutch, and my petal pushed very hard. When I changed over my trans & tcase I installed a Centerforce II clutch - very smooth, nice, it grips & holds well.
If you are looking to go four wheeling, the T-150 & Dana 20 combination leave alot to be desired. I went for the NP435 & Dana 300 combo and love it (now my first gear high range - NP435, is what my first gear low range was - T-150/D20). Later, T.J.

if the clutch is slipping, you should be able to smell it
Thanks all....When the clutch slips, you sure can smell it. It smell like burning brake pads, or should I say, it has a odor unlike burning oil or gas. But since I have made the minor adjustments, it has been fine. I am going under to look at the linkage today to see if it is worn out or what may have caused this. I tell ya, my clutch pedal is very heavy. So much that my little lady can't push it to the floor. Maybe I will look at replacing with a centerforce....Thanks again all for the advice...I am sure I will have many more ignorant question as trail season nears!

you'll likely need to replace the clutch soon

Yeah, if you play to much more, the way it's sounding, you might be replacing the flywheel, instead of just resurfacing it.
The Centerforce II allows me to push the clutch petal down with my hand (for checking clutch adjustment), that to me is kewl. (My little lady dosen't have a problem pushing the clutch in now either).
When I recently installed a 1" body lift to my CJ5, I had to modify my clutch linkage, that's when I noticed the 29 years of use. Holes enlongated, rod ends almost worn off, it was an accident waiting to happen, that's why I mentioned it in my first post. So take your time inspecting all of your parts, remember your CJ has been around for a while, and if you don't 'know' the PO then it's wise to do a very good checking out from bumper to bumper, (if you haven't already).
