In Reply to: NAA Hyd pump Loses Prime posted by Money Pit on Tuesday, November 26, 2013:
Couldn't check this site at all yesterday. My computer went south and I had to buy a new one. I know very little about the hydraulic system on these tractors. Mine still has the vane type pump and works reasonably well. But I agree with Bob. If it's loosing prime, then air is getting into it from somewhere. If it isn't leaking onto the ground, then it has to be leaking inside the sump, I would think.
