I'm new to this forum but hoping for some guidance. I have been looking for an 8N or Jubilee and recently found a Golden Jubilee for sale by a local man who repairs Ns and Jubilees. The price was fair, but the only problem is the hydraulics didn't work. He was very confident the hydraulics could be fixed with a new o-ring and leather gasket on the piston. The hydraulic pump is operational. So, I offered him the asking price if he fixed the hydraulics. Well, he called me yesterday to say he had done the repair (piston gasket) and they hydraulics still do not work. He's basically saying he doesn't know what else it can be and has referred me to another somewhat local "expert" who he said could undoubtedly fix whatever is wrong. My problem is, he's not offering to pay for whatever additional work needs done. My other problem is that I've already paid for the tractor! So I'm in a little bit of a conundrum so to speak. Can anyone give me some ideas on what the issue could be and what kind of money I'm looking at to do a repair? Are there any valves that could be needing replaced, or could it be the piston itself? Any help would be much appreciated. If the cost to repair is reasonable, I'm inclined to go ahead and do it because I think I got a good price on the tractor, but if this is a major issue of some sort I want to press for my money back since the deal was that the hydraulics would be fixed. Thanks!
