310 Roundnose Clutch?

My 56 has the double clutch plates. Can't get them from Case any more and a local Chicago firm' SURGE DRIVELINE does them along with all types of antique cars and trucks. The parts guy told me to get him the correct thickness for re-facing them. I am hopeful the service manual has the info or you know the spec? SURGE is in South Holland, IL, a Chicago suburb and came recommended to me by my engine machine shop.

I had a business here in the Kansas City area recommended to me by my local Case dealership. They may be a second option to reface your discs. They turned a flywheel off of my 630 and did it very reasonably. I will also be sending them a clutch disc to rebuild in the near future. - Joe

I do have good used plate for double clutch on 300 round nose. e mail is open jc

I have the double clutch also. Years ago I ran into a simular problem -Not available. I took it to Boston clutchh to get rebuilt.When I put it together I couldn't release the clutch,they had made the facing too thick. I took it back and they took some off the flywheel to compensate for the extra thickness of the disk. Now I have more material on my clutch ,but on the otherhand if it goes again I don't know what the correct thickness of the disk is. Just thought I would pass this along. I should have mesured the thickness and the assembled height after it was working correctly.

The used ones have about 1/8th of an inch left on them. When I replaced the clutch in my 69 580CK last year, I recall the new plate being about 3/16ths or so. But it is a single driven plate. My friend looked at the used ones and said they would last a long time but I believe in the old adage about splitting it once.

I have the friction linings w/rivets kit G45043 for the G11077 standard single plate clutch used on 300"s.

The new friction linings measure exactly 1/8" thick.

Thanks Joe, You just saved me a couple hundred bucks and I will have this 310 back together this week now.

I saw the other thread on the release bearing and it is instructive to note that my tractor (double clutch) has a single clutch release bearing on the shaft. It too was in good shape. The needed bearing is no longer available but the use of the other type works in mine. The depth of the bearing where it meets the pressure plate fingers is wrong since it is supposed to actually fit over the fingers a bit, but still contacts the fingers enough to work well. The stop, which is supposed to be a roll pin but is the bent tab found on the single type also works. The bearing matches the Service Manual drawing and picture of the single type.

I am guessing the clutch and bearing was recently installed before I bought it at auction and the PO could not get the bearing like the rest of us who have the double discs

My guess on why all this works is simply because the adjusting rod simple design allowing for lots of threaded adjustment which makes up the depth. I was surprised to find it working in the tractor when I spilt it. I assumed the single clutch and release bearing went onto a different sized/spined shaft. Without specs on either I can't verify why this works. I know the fingers on the pressure plate are being rubbed in the wrong spot but the metal thickness is the same and no uneven wear is evident.

Not a recommendation, just my experience that may be useful. Thanks guys.

The single plate clutch is 9-1/4" Dia. I think the double plate clutch is around 8-1/2"? Dia. I doubt the single friction linings can be made to work.

jcmarleau, do you have a pressure plate for a 1956 Case 310 utility tractor dual clutch that you can sell?
