In Reply to: Rockwell clutch? posted by Idaho Ron on January 09, 2009 at 04:51:27:
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.
