[QUOTE="tubby's repair, post: 48148, member: 4909"] This machine had water in the hyd system and froze last winter. When it was started it made a popping sound and lost all hydrualics. I took out the screen on the inlet line to the pump and cleaned it. Removed pump and found that it was bad (internal). Replaced pump and changed fluid. The problem now is that it still has no charge pressure. I pulled pump back off. No oil getting to pump. After pulling pump, i cranked the engine over and the splined section on the hydro pump is not turning. I can see the shaft on eng flywheel turning, but i dont know if it is turning the hydro. Could there be a sheered key on the drive? And if it is do you pull the engine to repair ? Thanks for any help. Wes [/QUOTE]
