47-55.1 Clutch

[Dachshund]

Where do I find the HD 10 3/4" clutch that won't cost me an arm? The pressure plate is good, but my disc has a broken spring. The plate is the one with 9 holes.

I'm trying to think what year, model and engine and trans you have. I'm old and I don't remember those things off the top of my head.

I got mine at Rockauto

Well....stupid computer! I "edited" the post to tell what year and motor, but it didn't take! It's a 1947 (late) 3600 with a 1952 216, and a 1954 head. Stock transmission.

The one for a 9 hole plate??? Did not see it listed. Do you know the part number?

Can't find a 10-3/4 on the Rock auto site. 10 1/2 are easy to find and will work fine unless you plan on using the truck to pull stumps. That would be loosing 1/8 inch friction surface on the outside edge of the disk.

Why are you hung up on this "nine hole plate" thing?

It would also save you 100 dollars on the disk alone. Chevs of he 40's shows the 10-3/4 disk. Spendy as you already know.

A better option might be to contact http://kyclutch.com/ or an other clutch rebuilder and send your disk in and have it rebuilt and be done with it. I would at least check with them or a clutch rebuilder in Missouri.

Here these guys are in Jonesburg http://www.uniqueclutches.com/

Another one that I used to deal with a lot is Waco brake and clutch in Waco, Texas their shop used to be about a frisbee throw from the silos that everyone's wife has on their bucket list to visit now. Not much in the way of brake shoes or clutch disks or pressure plates phased those guys back years ago.

just a heads up on clutches.
if the clutch is worn out then the flywheel is usually heat treated in spots on the friction surface that got hot. I mean spots, not all around the surface. these spots become harder than the other areas on the surface so they wear less in comparison. a new disc bearing against the unmachined flywheel will make the new disc wear into those high spots which will prematurely wear the new disc and may also make the clutch chatter when you slip it a bit to get moving. in short, if you are gonna take the whole thing apart anyway, you would do yourself a favor by having the flywheel ground at the same time. I say ground because a regular cutting tool bounces over the high spots so it doesn't leave a true flat surface. a clutch kit would include a disc, a pressure plate. a release bearing and a pilot bearing. other things to check would be the release fork contact surfaces and pivot ball as well as the splines on the trans input and the linkage wear points.
just food for thought

A new disk might chatter on a flywheel with hot spots for the reason that Dsraven mentioned too. If my sister ever drove it the whole flywheel would be one big hot spot because she used to think that clutch pedals were foot rests.

Yeah....had the flywheel ground. The plate was nearly new...if it wasn't for a broken spring, I'd put the disc in. Not sure how it was broken....did not see it on teardown.

[mr48chev]

They break or fall out. Maybe the last guy got stuck in the mud and tried to rev the engine and let the clutch out too fast to rock it out.

I'd contact one of the rebuilders i posted above and see what they have to say.
