The Stovebolt Site Forums The Shop Area Engine Shop Again...11" flywheel w/T-5 tranny...clutch????

I've searched but am not understanding 100% of what I'm reading so, if you'll be patient with me...I've got a 261 with an 11" flywheel and a three finger pressure plate. I've done the modification to the input shaft and bearing retainer front hub on the T-5 - bolts up nice! Next is what clutch do I use??? The Astro Van 10" or 11" or ??????? I read somewhere the the 10" will work eventhough it is smaller than the stock O.D.

Thanks fellas,
Tom

if you run a 235 then you have to trim down the coller and input shaft on a T5. Larger mtors like a 292 and ?? other motors you don't have to trim. I run an 11' corvette clutch but you're best bet is to take your pressure plate to a clutch facility and have them match what you have. a 'FLAPS' will usually only sell a complete clutch and pressure plate set. Make sure you count the input shaft on the T5. some are 26 spline while others are (14-16?) spline & know the diameter of your flywheel.

carolines truck:
I was just rummaging through the back of my shop and discovered a new 11" pressure plate which bolts up the the existing truck flywheel. This was a left-over on a previous T-5 tranny I used on another project. I think I'm in safe territory now. I'll just have to find a 14 spline (not 16)11" disc and I'm done. I am running a 261 and have already performed the modifications to the input shaft and collar as I said in my original post. I hope it is as simple as I anticipate. Thanks for the info.

Snegrah,

Look at an 82-84 S10/S15 2.8L. It is a 9 11/16" x 14spl. x 1". Close to 10 in. as I could find! NAPA part No. RCF-4201. Check it for fit on your 11" pressure plate. The plate should cover all the disc.

Hotrod6;
I just ordered a 10.5 disc 14 spl. x 1" from Summit! I do not see why this one won't work. If it doesn't...RCF-4201 it is!

Thanks!
Tom

I'm running a Schiefer aluminum flywheel which accepts a 10" clutch (actually measures 9 7/8") behind my 261 with an original 37 transmission. I'm counting on that RCF 4201, which I was told was a 9 7/8" clutch, 14 spline, to fit perfect. I don't have one yet, but I'm heading to get one tomorrow at my unlocal NAPPA. I'm hoping to buy just a clutch. I must have 3 or 4 clutches and pressure plates and I don't need anymore pressure plates.

A lot of good information on clutches here.http://www.ramclutches.com/Products/clutch_disc_apps.htm

I just went to a local clutch guy and he made a new disc for me with the proper splines worked great for about 25 bucks. If all else fails let me know and I would have one made for you.

I got lucky, my t-5 came from an 85 v-6 s-10 and when I pulled it I grabbed the pressure plate and clutch disc. The clutch disc was identical to the stock one but with the correct number of splines but the pressure plate bolt holes were different. I test fit the s-10 clutch with the stock pressure plate and it worked fine- and since it was in pretty good shape I'll use it til it wears out and then replace it with one just like it.

I'm using the RCF-4201 with my T5 behind a 55 235, which is a 10" disc that goes in an 83-84 Firebird w/2.8 V6. The center spline (14) is very compact and there was no need to grind or refit the disc. Disc was about $43.00 from NAPA.
