Zane Not any more. Simple and inexpensive conversion to a modern gear pump. I have three units in the works right now. TOH This post was edited by TheOldHokie at 15:21:33 08/14/12.

It will be in the larger tube or intake tube or its connections. If you find no leaks then it's probably going to be the hydraulic pump seal. The piston pump will pump no air. If it is the original vane type pump you are in for more trouble as the parts are hard to find and harder to have a sucessful repair. Parts for the later replacement piston pump are easy to get. Like the man said. It's the seal. Maybe the shaft and the needle bearing etc. Zane [Reply]  [No Email]

As for air in the hyd that can be as simple as a small hole in one of the lines or even the pipe plug in the pump not being as tight as it should be [Reply]  [No Email]
