    I have a problem with a plow truck that I have bought. First is that it is a old belt driven hydr. unit and parts are hard to find. Second, the plow works great except for the plow will slowly leak down. I know very little about plows and their mechanical parts so I am looking for any info out there. I have been told by different people all I need to do is rebuild the lift cylinder and flush the system. I have located a guy on ebay who has (supposedly) the parts for the rebuilding, but can anyone tell me how to flush and rebuild? Also one person told me the problem might be in the trip valve??? What is this, where is this and is it fixable? I have contacted my local meyer dealer and they did not have any repair manuels nor could they get any.

    If you have fluid leaking from your lift ram, then it needs rebuilt. If not then the the problem is probably with the control valve under the hood. Follow the cables through the firewall to the control valve. It could be an adjustment problem with the cables. If not then you will need to disassemble the valve and repair the o-rings. I have no idea where to get a kit, but a hydraulic repair shop should be able to hook you up with o-rings.
