Are you going by part numbers or casting numbers?
This is what I show for the later cylinders.
Old Magnet, thanks for the info. Those are the cylinders. The sealing rings in mine are two per groove for a total of six per piston. I'm not too fond of that arrangement as I don't think that they seal too well. This and the fact that there was a large amount of mud in the cylinder probably accounts for the blade not staying up. The bore was not in the best shape either. However, I cleaned it up with a Sunnen cylinder hone and flushed it out with varsol. Here's hoping it helps. The previous owner's story of replacing the sealing rings does not hold up in view of what I found. Once again, Old Magnet, thanks for the info. Now I'll see if I can still get parts.Cheers, Larry.
Larry,
I think these are the new Cat part numbers for the seals in the D2 cylinders they are the numbers I used to
order new seals for my D2 in 1999 !
2x 8C9133 Seal lip type

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
