53 3b V6 Clutch Short Throw Prob

Hello,, I picked up a 53 cj-3b ,, Buick 231,, t90 trans,, overdrive,,, it had a modified clutch cable attached to the bottom of the pedal,,, they adjusted the clutch so tight (pulling on the clutch fork) to disengage the clutch,,,, but it did not have enough play to disengage the clutch,, thus clutch slipping,,

I installed an advanced adaptor chain control,, even adjusted to zero free play, I can not disengage the clutch,,,

researched parts installed by last owner and they appear to be all cj5 v6 clutch parts (including the clutch fork)

All parts purchesed thru Kaiser
1378486 fork
907588 bearing carrier
948692 pressure plate diaphragm
994841 disk
3752487 pilot bearing

thinking about modifying clutch pedal to be longer to gain more throw? Or do I have the wrong clutch parts?

 

With both cable control or the Buschert chain type control you would have sufficient travel.
Sounds to me that the driven disk may be installed backwards ? Also could be a mis alignment issue going on here.
I think your going to have to take this apart to discern the issue.
Take pics and we can better see exactly what’s up.

 

Also I’m wondering where or a what point is your linkage is attached to the pedal lever ?

I think this may be a factory lever for use with cable control but just not positive.
Perhaps someone with a factory cable control clutch system can specify the factory location for attaching the cable clevis to the lever.

 

The original cable was attached to the lowest hole on the clutch lever,, I was going to try and move it up,, but that the chain/gear setup would give me a better throw ratio,

 

So does the 231 v6 with Buick bell housing use the stock cj5 clutch parts? Or does it utilize a different clutch fork? Best place to purchase a proven kit?

 

You can guess all day long....but if the previous owner had problems with it, something is not right.
We don't know if the t/o bearing is positioned properly on the t/o fork.
We don't know what fork pivot ball has been installed.
We don't know if the disc is installed correctly.
We don't know if the disc hub is bottoming out on the input shaft splines.
We don't know if there is a bell housing alignment problem.
We don't know....and you won't know until the transmission is removed.
Sorry.

 

Yeah what Jim said. Also we don’t know what bellhousing you have but it appears it could be a 9774035. If so the bell number should be stamped (small) on the left side.
Nor do we know what adapter plate was used.
A correct adapter plate will be exactly 2-5/8” thick.
If the location of chain control attachment to the lever does not fix the problem you most likely have no option other than disassembly.

 

I agree I will have to remove the trany to inspect,, I looked for part numbers on the adaptor and bell housing to help identify it,,, I am assuming it is a Buick bell housing,, kinda hard to take pics of it, but maybe someone can identify it

 

Any advice on who to order replacement clutch parts from? Order parts for a cj5 v6? Do I stay with the stock jeep clutch fork?

 

From what I can see it looks like you may have a “Trans-adapt” adapter and 9774035 bell .
Those parts should be acceptable.
The Buschert control and your clutch release fork also appears to be correct.

Absolutely no sense in buying any parts until you know what the problem may be.
I suggest you take it apart and show us a pic of the release bearing and carrier . Also take a pic of the release fork fulcrum point.

 

As Ken has stated, no need to buy anything until taken apart and inspected.

 

Ok,,, so when I start to take it apart,, does the throw out bearing carrier ride on the transmission collar ? Or the adaptor collar? Just trying to look for a misaligned throw out bearing? I assume the adaptor and transmission can be misaligned, causing the t/c to be misaligned,,, guess I gotta peel the onion back to see what’s inside,,, lol

so the guy who installed the clutch/trany used a cumalong off of the roll bar to support the trany,, I think this technique could be a back breaker good idea,,

 

Accessing the clutch is the no doubt one of the worst tasks required on any Jeep.
The release bearing fits onto the release bearing carrier. The release bearing carrier slides over the transmission front bearing retainer. (AKA input snout)
Most but not all adapters use a separate bearing retainer for carrier to ride on.
So we may need to see the adapter plate configuration.
The fulcrum is threaded into the rear face of the bellhousing.

Sing along now…..
The neck bones connected to the back bone…….
The toe bones connected to the foot bone……

I’m presently thinking you have an issue with the way that the release fork is attached to the bearing.

 

I’m fairly certain you will have two bearing retainers. One attached to the transmission that has had the snout cut off and another full length retainer attached to the aluminum adapter plate.

 

Does anyone know the length of the t90 input shaft utilizing an adaptor?

 

The oal for the t90j maindrive gear is 11-1/2”
