I ordered the Zoom clutch set. It isn't right. It too must be for a big block though they say it is for a 292.



I'm going to try a Bronco pressure plate, re-use the old disc and hopefully it will hold out until I can do the 5 speed conversion.

Well,

The bronco clutch plate will not work. I ordered a replacement from Mac's. It isn't right. I've come to the conclusion that there just are not replacement clutches for Y-block trucks.

Any of you other trucks out there know of anything?



Since I want to drive the thing I'm just going to re-use everything clutch related. Hopefully the pressure plate's not warped too bad. The flywheel sure was.

Charlie,

      There's an outfit in Fort Wayne, In that can make you one, also one in South Bend,In. What exactly is the problem with what you ordered, and what do you want?

The Zoom clutch kit I ordered, advertised for a truck with a 292, must be for the big block - or something other than a 292.  The pressure plate bolt pattern is drilled on a larger circle than The 11" pattern on the 292 flywheel.  The pilot bearings had a larger id than required.  I don't know about the od.  The clutch disc was a 12" with a 1 3/8 -10 spline.  The disc would have worked if the pressure plate would have bolted up.  The throwout bearing looked correct.

The bronco had the smaller input trany and so the pressure plate fingers are closer together than those of the large input.  I was just taking a chance here.

The one I ordered from Mac's, to fit '48 - '64 trucks, was for the smaller input transmission.  They had no alternative.  The picture representing the part looks exactly like the part I need.

Ideally I would like something with a little more holding power.

The clutch would slip on hard acceleration.  At disassembly I found that the flywheel had started to crack which, no doubt, contributed to the slip.  The pressure plate wore uneven.  The 3 fingers were not at the same height so the throwout bearing pushed on two fingers to start out.  I did not notice this when it was assembled.  The 1/3 of the pressure plate corresponding to the third finger has hot spots so it has probably warped some, also contributing to the slip.

Because of my speed addiction, the engine has been modified much more than I intended 5 months ago.  I don't think the stock clutch will act favorably but I don't know what the stock clutch is designed to handle.

Have you any experience with either of those outfits?  I may go that route if stock doesn't hold.

Charley, have you checked with the guys on the "Slick 60's" site? Someone over there might have an answer.

Charlie,

Look for a larger truck application, I have a 58 F500 w/272 and have a few transmissions around that came out of big trucks with a PTO and They all have the 11" pattern with the     1 3/8 x 10 spline. I am sure it is the same setup you are looking for.

When I got the combination for my T10 conversion, I went to NAPA and looked through their applications and compared part numbers until I found the same part numbers (I.E. looked at 63 galaxie pressure plate numbers and matched them to a 292 truck pressure plate number) then found a kit using that number and the matching clutch and throwout bearing to fit the spline of the transmission.

I made a post on FTE but not the slick60s. I guess I could try that as well.



All of the clutches that come up in the catalogs of local parts stores are the 12 inch clutches. I think they are all made by Zoom. The Zoom clutch from summit looked exactly the same as the 12" clutch kit I got at advance auto parts. Of course, both are incorrect.

I didn't have any trouble finding what I needed a few years ago. I'm at the point where I don't want to order more unless I can see a picture of the actual part before it is shipped. Most places will not accommodate that request.

          OK, you need an 11 inch clutch, Have you faced the  flywheel to remove the heat cracking? If the flywheel itself has actually started to crack, REPLACE it. You do not want to see what happens when a flywheel breaks. You now have anoption in the pressure plate department. There's three styles available, Borg and Beck, Long or Diaphragm. Ford generally used the Long style. The diaphragm has a nice light feel, The B&B is a good compromise. I run a diaphragm with a Kevlar disc in the red car, works pretty well with stock type tires. Don't think it would hold slicks.

 Next, is simple, order a clutch disc for an 11 inch pressure plate with whatever size and spline count your tranny is. I'd suggest a McCloud or Ram, dual friction. Use new everything, grade 8 bolts for the pressure plate, new throwout, check the pilot, make sure it's not worn out, also check the throwout arm for straightness. Make sure the pressure plate and disc are designed for each other. the disc thickness is a factor.

I have replaced the flywheel with a new billet steel unit from JM.

The problem I'm having with the pressure plates is that the ones that will bolt to the flywheel are designed for the small input transmissions. If I place the throwout bearing over the fingers, as it will be aligned when installed, I can see the tips of the fingers through the id. This means the fingers will come dangerously close to the input shaft and may touch when the clutch is disengaged. I've talked with a few people about this and no one has been able to say without a doubt that it will or won't work. I don't really want to be the guinea pig here.

A big input pressure plate from a big block seems to have the mounting holes on a larger circle than that of the small block so it won't mount to the flywheel.

I wonder if the big block plate would fit in the bell housing if I had the flywheel drilled for that pattern.

Finding an 11" pressure plate is easy. It's finding one to work with the large input shaft that is being a pain.



Thanks for the help on this y'all!

Charlie,

        Have no problem with that issue on mine, but it's a 1 1/16" 10 and I used the diaphragm Press plate. The only issue is that I have to run with very minimal throwout to finger clearance in order to have enough travel in the linkage. I can check to see what they have at SB clutch if you want. I would also recommend you pick the phone up and call Ram or John and see what they have.
