I am trying to find seals and what not for D2 hydraulic pistons. I can't seem to find the correct 44 Hydraulic control book. There is a part number on the closed end, which I was told you could identify the cylinder. I called CAT and that was a waste of my time, they had no idea about the part # 8F2657. Would someone be kind enough to scan the page for me or get the manual form #? Just want seals and packings, are these parts the same as D4 but in a shorter cylinder?

Thank you for your time and reply.

8F2657 is part of assembly 8F2660 or 8F4045, here is 8F4045.

I'll if this is what my uncle need for their bulldozer project. He's not a techy person so he always ask me for some online search. I'll just finish installing the brake kit, wheel and tires on the Wrangler and I'll visit them and see what else they need.

We did a set of those a couple years ago from a barn find D2 I waited 25yrs to purchase. They were leaking so bad you couldn't use the blade at all. My son did them at his work where they rebuild giant hydraulic cylinders used in the mining and steel making industry. I'll see if he remembers what he used to repack his.
