What Parts To Get?

Hello all,

I have a 63' CJ5 with the rare Buick 198 V6 in it. I am still trying to dial in the clutch pedal with the clutch itself. I have changed parts such as the pedal shaft and pivot bracket, etc. I have not pulled teh tranny yet but i am wondering if i need these parts...

Throwout bearing
Clutch fork
Clutch itself

etc...what do i use for searching. I am assuming it would be a 1962-63 Buick as all of those parts were with the motor and bell housing correct?

Then if i am able to find them, which may be hard, yes still have the pedal to the floor to disengage clutch, is there anything i can do to upgrade or change pedal linkage, etc?

Ideas...?

 

The pressure plate would be Buick
The clutch disc may or may not be depending on what Trans you have....

 

and if you do crack open the transmission you may as well replace it all, since its all apart anyways. no point in opening up and fixing one thing, just to have to open it again in a few months to replace another thing.

what transmission is attached to the engine?

 

He is showing a T-90..

 

Yes T90

 

Jon, you understand what's going on? You need a clutch disk to match the transmission, and a clutch cover (pressure plate) to match the engine. The disk has to fit under the cover so that the springs in the hub and the hub itself do not contact the throw-out bearing, flywheel or cover when the cover is engaged or released. The throwout bearing must be compatible with the release arm and the cover. The cover should be whatever the Buick used, but it could be the same as what you'd use with a Chevy V8 conversion. The Novak site should tell you what clutch parts you'd use with a Chevy. If you have a Buick bell housing and a plate adapter, the only part that could be different from all-Buick is the disk, chosen to match the splines of the T-90 and the diameter of cover. If you have a conversion bell housing, the manufacturer chose parts to work with their design, so parts choices could be a little different. I think the best option then is to match what parts you have and try them.

In addition to what Tim said above, another part to consider is the throwout bearing. This usually consists of an actual bearing, and a carrier sleeve that the bearing is pressed on to. When a conversion is done, these parts are often "borrowed" from some other application. You can match the bearing number to get a replacement (this is usually the only part that may need to be replaced), and reuse the sleeve. Sleeves can be different lengths to accoount for different style pressure plates (Borg &Beck 3 finger vs. diaphragm style).
With a conversion that was not done by you, or was a known kit, you usually have to pull things apart to find out what parts were used. Many times, stock factory parts were mixed and matched to make things work, other times, an aftermarket company made their own conversion bellhousing (and sometimes throwout carrier) to make factory parts work together.
I used to run a Buick 215 V8 mated to a T90 using a Buick bellhousing I believe from a 198. I had to use a 3 finger clutch that was less than ideal because I couldn't find a diaphragm style with the correct distances for the throwout sleeve.

Thanks all. Yeah, these conversion type projects are challenging. I get spoiled with plug and play projects. I really do think the clutch etc is good. Again, my issue is the PO did not dial in the pedal actions. Some parts are worn in the mechanizm on the pedal and linkage, but i am concerned that it really is about the fork, pivot, and throwout bearing. I did look at Novak and emailed them but they never responded. I am starting to think i need their adjustable throwout bearing, longer GM fork and adjustable pivot. I am about to get their T90 rebuild kit so wanted to attack this issue as well. Dont want to be grinding he new gears etc with insufficient pedal action.

As far as i can see i have the 198 and buick bell. I do not see any adaptors etc as i have read they bolt right up to the T90 J i believe.

 

Go to Advance Adapters out by the airport... 4320 Aerotech. Talk to Steve, Matthew or Randy. They can give you all dimensions you need. They also stock all the individual clutch parts there. Randy knows clutch systems inside and out. Matthew also does work on the side, although he will bore you with Landover talk

 

Also, I would seperate the engine from transmission and go to measuring the parts you do have. Inspect them for wear and also their stack up height. You'll need to measure all clutch components, input shaft stickout, bellhousing depth and measure their corresponding pieces. Easiest way to do this is use the bellhousing face as one and the back of the block as the other. A framing square makes this easier.

 

Cool Yeah i have known of that place for many years but havent made it out there. Again what i have "works" but can tell its not dialed in. Thanks will give them a try to be local heros!
