Rockwell clutch?

What is the difference between a standard clutch and a rockwell on a SC? Thanks. Ron

It's "ROCKFORD", and the difference is the clutches were made by different suppliers.

Sorry for the mix up and Thanks for the info. can a guy still get parts for both? I found a fixer upper SC that I was thinking about getting mostly for parts. The owner said it had a "rockwell" clutch. He said the clutch was bad, and it had not been started for a couple of years. I know the carb is missing but the rest of it looks to be in good shape.
It has a fast hitch and a 2 to 3 point converter. Ron

Trouble is, that could mean different things. Bad throw-out bearing? Clutch disc worn? broken finger? Something broken on the fork? Out of adjustment? It would help if he could describe the symptoms in more detail.
When I overhauled my Super-A, All the parts were available. The flywheel needed to be re-faced, and I just went with a new disc, new pressure plate, and new TO bearing.

Ron: It's Rockford and the older clutches were Auburn. Rockford is a bit heavier all over and pressure plate has 6 springs compared to 3 in the Auburn. That difference applies to SA, SC, etc.

My SA is a mid 53 model, if I recall IH started installing Rockford in SA less than a 100 serial numbers after my tractor. My SA never saw much heavy work thus the Auburn clutch lasted until 1992. When I changed it the weight of the new Rockford pressure plate was noticably heavier than the old Auburn, and the spring count very noticable. I think most of the Rockford changeover occured in 1953, right from the SA to SW9.

The only thing I remember about the larger tractors, is my dad changing our H from Auburn to Rockford and it was much harder clutch to depress. Bear in mind I was only 12 at the time. Those either had more springs or much stiffer springs. Prior to that IH had a reputation for poor clutches, especially as farmers started buying loaders. Dad's H was a 51 with a loader, and the Auburn clutch only lasted 3 years. The old H did get excessive loader use as we had 5 neighbors without loaders, thus dad made the rounds loading as many as 5 spreaders all day for a month.

Ron, I can have those clutch parts on your doorstep in 2 to 3 days.

Thanks for the info guys. I have not decided if Iam going to get it yet. If I do I am going to take the parts I need and pass the rest along to a friend that needs some parts. Ron
