I'm getting ready to rebuild the hydraulic lift and power steering assist assemblies on my IH 354 and am confused about some o-ring descriptions in my parts book.
Here is a typical book entry:
352 221 R1 "O" RING, 9/16" x 3/4" x 3/32" (class 6)
I understand the sizing alright, but what is "class 6"? Is it o-ring material? I expect most of the seals in these assemblies are buna-n (nitrile). I don't want to pay many dollars for single o-rings that should cost a few cents unless it is necessary for the specific application.
How do I find dimensions for o-rings that are called out by part number without the description? It would be easier to have dimensions than to measure grooves and old o-rings to come up with a fit. It's not hard, but I could have the seals purchased and on hand before the disassembly begins.
Thanks for your insight!

Jon called me to help him discover why his tractor wouldn't start
