You should have 1 1/4-1 1/2" pedal free travel.
Ck linkage for wear-ASAP
Ck tranny mount for movement.

My tranny mount bolts were tight and my linkage is in good shape. I have the kit with the heim joints. And my freeplay is good but going into first doesnt feel right

HI try taking away some of the free play up top so you engage more clutch and see if that helps.. also check the fluid level might be low??
good luck

hello

the actual free play you want on a cj with a 258 or the 304 is 1 to 1-1/4 of a inch. i always run mine at the 1 inch mark. if you have to much free play on the top that means that you are not pushing the pressure plate enough to release the clutch disc completely and the disc will drag and not want to shift. at one inch and a fairly new clutch i have about a 1 inch at the bottom. letting the pedal up about a inch it starts to grab the disc between the pressure plate and the flywheel.
check all of your clutch linkage for wear because with alot of wear can give you issues. on jeeps when i do a clutch i also always replace the linkage assy parts also.

Note, as the clutch friction plate wears.
Pedal freeplay is reduced.

hello

cj's ran about 1 inch of free play and the FSJ ran just over 1/2 inch in the early 80's. IAW the FSM. my rule has always been i want as minimum amount of free play in my pedals. from the time i ran bugs,civics and jeeps ive always adjusted them all the same way with a small amount of free play. as long as i had a little bit of play in the fork and throw out bearing it was good. that always gave me a great feeling balanced clutch that i have enjoyed. that is part of the reason i have always loved having a mechanical or cable linkage system. very adjustable and it passes on the feel of the spring in the pressure plate. you can feel the change of tension as the clutch is engaging.

Not the bell crank, The release arm.

I also had a heim joint linkage and oneday I suddenly had about 3" of freeplay and when I went underneath, I saw the short linkage arm had punched through the end of the release arm.

It was like, wow, never thought that could happen.

That could be caused by pedal travel being to long. Pushing the pedal all the way in, as usual, but links are at their ends and throw out bearing has no more room to move. Pedal pressure eventually pushes the adjusting rod through the lever arm. Proper pedal freeplay adjustment is what will eliminate that.
