The Stovebolt Site Forums The Shop Area Driveline S10 T5 to Stovebolt clutch disc help needed...

OK... I know there is a ton of info on this all over the place on the internet... maybe that is the problem... information overload!
Can anyone give me this simple information?

I am fitting a World class S10 T5 to a 1955 235ci stovebolt with 12v flywheel and 10" clutch. I am not running an adapter/spacer between the box and bellhousing and I am using the original 235ci pressure plate and realease bearing.

All I want to know is what 10" clutch can i use with this set up? A supplier, part number anything... I am in the UK so don't want to order the wrong one obviously.

Thanks in advance
Tim

What is the spline count on your transmission? You need a clutch that matches it and is 10 inches.

14 by 1" but I have seen various posts saying about different discs having different offsets and not clearing the flywheel. I have only seen mentioned once a part number of a disc that will work but when I googled it it came back with nothing.

Here is a suggestion. I'm not trying to complicate your life. I hope you see this as simple.
I recommend that you convert the 14 spline input shaft to a Jeep 10 spline input shaft. Then you will be able to use the standard factory 10 spline clutch kit that would be the stock replacement for your truck. The 10 spline Jeep shaft is 1 + 1/8", so it's a little stronger than the 1" X 14 spline S10. Here is a link to my DIY Jeep shaft swap for the S10 T5. I actually had a world class Jeep shaft for the DIY post, but they are no longer available.

Since you have a World Class S10 T5, it will have a fiber style synchro rings. Since only non-world class Jeep shafts are available, you would simply exchange the fiber synchro ring for 4th gear with a brass synchro ring.

If you decide to stay with the 14 spline shaft, then you have several options for discs, but I have no idea which will fit properly for your pressure plate and flywheel. Some of the info I have collected is below.
I just answered a similar question in another thread - so I just copied it below.

This is new territory for me. Some may find it hard to believe, but I have never installed an S10 T5 with 14 splines (only 10 splines after the Jeep shaft swap).

I do collect info to help others however, so I'd like to know the part numbers you are dealing with.
I've spoken to Dave Farwell on a few occasions and he's a great guy and a great resource. Two thumbs all the way up!

I know Speedway Motors sells several 14 spline clutch discs that work with T5s. You would want the largest diameter that your flywheel and pressure plate can handle. Here are some links to the clutch disc at Speedway Motors.

This Speedway disc is 9' which may be too small.

Speedway 10" disc.

Speedway 10.5" disc

Also, these are usually in stock at Rock Auto.

When I put a world class Camaro T5 in my "54 I used a 12volt flywheel from a 55 car with matching pressure plate, and I believe it was a 14 spline 10.4" disc from a Camaro or Corvette with t-10 4 speed. The disc hangs out of the plate a wee bit but doesn't seem to affect it. Worked for me.

Measuring my flywheel and the clutch that came off this would be a perfect solution as the clutch was 10.5" and did overhang slightly. The only problem is that I can not find exactly what car they came off. I really need to know this so I can try and get one from a local supplier in the UK as time is an issue. I can see them on speedway but they are talking about a 2 week shipping time which is ridiculous!

Anyone know a car that had a 10.4" 1" x 14 spline clutch as standard?

Thank you for all this information, I Don't want to start messing with the gearbox regarding the shaft etc at this point.

I have actually already been in touch with Dave Farwell and he is being helpful, I am hopingt to speak to him on the phone at some point today...

Found something but not very cheap. Try searching different years of Jeep clutch discs. Most I have seen are 10 spline but I know for sure that some used 14 spline.

Advance Adapters Jeep Disc

That's the disc I've been running on my '60 235 /T5 since '07.

Great! Did I do good?

I have a jeep 14 spline clutch dis I was going to use..came out of a jeep TJ.4 cyl disc size pretty much the same as the originalI don't remember the year.I had no doubt it would have work fine but I went with the input shaft conversion,it made more practical sense...

Thanks Lugnutz, I'd follow this up but Dave Farwell is sending me a '83-84 2.8 camaro disc which is 14 x 1" and 9 11/16" so all sorted now... I hope!

When I search for 1983-84 Camaro clutch disc, they all seem to be 9 + 1/8". Please share the part number with us.

The 1983 and 1984 V6 S10 pickup uses a 9 + 11/16" friction disc but it's hard to find a supplier that sells just the clutch disc.

Yes, smooth engage.
