630 Clutch 10 A36147

I am replacing the clutch in my late model Case 630 diesel, and ran into a bit of a challenge.... Apparently there are two different versions of the same part number A36147. One is called a Auburn unit and the other a Rockford. They are both 10" and both have 17 splines. The difference is the "shoulders" of the inner segment of the disc which cover the springs are too high on one of the clutches. They contact the inner cavity of the flywheel. Both of the clutches below are part number A36147. The third picture below shows my old disc on the left and the new one on the right.

A couple of questions for the group:

1. Either I have the wrong flywheel on my 630 or the new disc is not designed to work on the early tractors. Is it possible that style of clutch was made for the later 430-530 / 470-570s?

2. Which one is the Auburn and which one is the Rockford...so I know which one to ask for....

3. Any ideas on a source.... A&I Products made the replacement unit I bought, but they do not have the other style.

I can't have mine re-lined. A piece of the inner section of the disc is broken (see third pic below)

Thanks in advance for any thoughts or guidance. - Joe





The clutch I removed is on the left and the replacement on the right.

I think you are putting it in backwards. I could be wrong, but I think the spring part should go towards the pressure plate.

I wish it were that easy. - Joe

Joe does the parts book show two different flywheels?( I don't have a 630 parts) or could you have the fly wheel machined to fit ?

Joe, my parts book shows a differant number for the 10" clutch for the diesel engine prior to #8191147 plate number g45780 is the correct plate for early 630 tractor.

Joe, I gave you the number for the early case 630 clutch plate number. The later plate number after serial number #8191147 is g45796.

G45780 was the original clutch for the early 630s which had a 10 spline shaft. It now subs out to G36145.

Mine is a late model (after serial number 8191147) with the 17 spline shaft. G45796 is the later clutch with 17 splines, which subs to A36147. The only 10", 17 spline clutch I can find anywhere is part number A36147..... and it appears to have 2 different hub possibilities. - Joe

I originally bought the clutch through an online dealer www.dealinapinch.com after searching for the part number A36147. When the problem surfaced, that dealer connected me with their supplier AI Products. http://www.aiproducts.com/products.html. AI Products researched the problem (I sent them detailed pictures), and they found a correct clutch, and had it hipped to me out of another dealer's stock. My pressure plate was still usable, so I did not need to source it... Joe

I have been in contact with AI and many many other suppliers across the country with no luck at all with any of them!! Would you mind giving me a call I'm desperate to talk to someone as yourself that I can go through some ideas around with, if I had your email address I could email you my phone# or you can email me privately and I can give mine to you that way [email protected] Thank you so much !!
