Over the weekend I decided to test the hydraulic PD (place diverter) and discovered that the cylinder leaks from the shaft. Does anyone know if the cylinder can be rebuilt? I'd like to avoid spending the 100 bux on a new one if possible.

They arent rebuildable from my understand. Look for a used one that is still good. Pretty sure JBP or Cyclone will have a used one lying around you could pick up for less then a new one.

Actually, they CAN be rebuilt. Looked into this when this same question came up over a year ago and it peaked my interest.! Why not? My Biesemeyer leaked a little too, so there had to be a cheap fix right? O0
Heres the problem.......They leak because possibly the packing is worn out, a gland seal has failed or the shaft off the piston has become corroded, bent, and/or pitted.......maybe .too much pressure........any way you look at it, not good.
Cheapest tiny hydraulic cylinder repacking kit I came across (Used all my old sources from way back when I rebuilt my pops Backhoe after the barn fire........another story) was $65. They had no problem matching me up with what was needed to do what I wanted to do, but the secondary problem was replacing and polishing the hard chrome on the piston/shaft assembly, which, more than likely, was the culprit of the failure........2 minutes into that phone conversation showed me that this was a dumb conversation to be having to begin with, more on MY part than theirs........
$119 was the cheapest I found that cylinder for. You'll NEVER be able to rebuild it for less than that, really....... ;) It's disposable, it is what it is.........
