Sherman power digger hydraulic cylinder

Looking for info on seals for a cylinder on my Sherman power digger.
The cylinder that pushes the boom to the right. It?s set up on a
Jubilee and I have a front
Mounted bucket made by Sherman as well. The guy at the hydraulic
shop is telling me it?s gonna be around 500$ to rechrome and bore
out the cylinder because it is in bad shape. But i think it?s salvageable
and I would like to just do it myself. This is also my first post.
 
Welcome Chance!

The cylinder may well be repairable. There may be some wear, not seeing it, hard to tell.

But the hydraulic shop can't take any chances on it coming back or causing some problem that they would later be liable for.

So, your choices are, let them fix it. Buy the seals and do it your self, see if it holds up. Or try to find a replacement cylinder.

The one in question is at the hydraulic shop now. I probably shouldn t have left it there. But here s a pic of the other side. Where do you think I can find the inside components?

Sure, you can do a DIY cylinder rebuild. However it doesn't seem as though seal kits are available any more for most Sherman equipment. Also there are multiple models of the Power Digger, you didn't say which one you have. Some manuals are still available if you know where to look online. Anyway cylinders of that era usually used stacks of V-packings for the piston and gland main seals. Cylinders also usually have a canned rod wiper and multiple O-rings (or similar such as square or quadrings). If you know how to accurately identify and measure, all of these things are available from a seal supplier such as Baum Hydraulics. The parts can also be matched up (usually) at your local hydraulic shop or industrial seal supplier. Additionally if you have de-chromed rods and a ratty bore a seal job may not seal, or may not last very long due to wear caused by roughness.
 
The hyd shop can supply the seals, if they will sell you just the seals. If they won't, try another shop, or buy them online.

BTW, that is a single acting cylinder. That means the condition of the rod is not that critical. It never has any pressure on the rod seal. The seal is only to keep dirt out.
 
Hi, if you can't rebuild a cylinder, sometimes you can buy a complete new one reasonable. Ed Will Oliver BC
 
I believe you are correct, I just compared and you are dead on except for which cylinder. Here is the cylinder and I need numbers 2, 4,5, and 6.
 
There is a good chance that rod was never chromed new. We had an old Shawnee backhoe, and none of the rods were ever chromed on it. We just greased them when done, and covered them with something to keep the weather from washing the grease off.
