I just bought a B7200 HSD with a "Kelley B10 backhoe" attachement and the pistones on the backhoe leak badly. I have tried to contact "CC kelley and sons" and they are supposedly in business BUT no answer at their phone numbers or email serrvice or Chat.
I need to get the piston seal packs for the "Kelley B10" backhoe. I am sure there is an equivilant or someone has the seal pack. If someone can guide me to an equivalant chart OR another way of finding the Seal Pack I need it would be greatly appreciated
Can anyone help?

I know you are probably wanting an answer in order to do this job yourself... But I have taken several cylinders off old or obsolete machines into a hydraulic shop that specializes in rebuilding cylinders.

Seems that they don't need the model of the machine or any other information to find seals. That leads me to believe that they likely just measure the diameter of the bore and the piston to find the correct seal...

Perhaps you would be able to do the same and check online retailers? Not sure though.

I think there are a few more measurements, groove width and depth . . ., some of which take tools which we don't all have. Some folks on here have used Hercules. They may have a seal set for your cylinders. Or, if you can take all the measurements, especially the rod seal groove, I expect they'll sell you the parts.

I have repaired a cylinder, using Kubota kits before they became so expensive and unavailable, without any special tools. Then I bought the rod seal tools, and that was an improvement.

But the Kubota kits, when available, have gotten so expensive I started taking them to a hydraulic shop. I take them off, sometimes loosening the gland and piston for him, take them to the next town and, in an hour or so, they're ready to reinstall. He charges around $100.
