[QUOTE="Condor, post: 17316, member: 1887"] The hydraulic pump wore out, locked it up, and snap the input shaft. The hydraulic pump is one of those deals that incorporates the charge pump at the other end, so when the hydraulic shaft broke, charge pump operation ceased. Besides lots of hours, I think I found the likely culprit for the hydraulic pump failure. The previous owner had replaced the 3/4" hydraulic output hose from the hydraulic pump to the control valve assembly with 1/2" (noting the hydraulic system relief valve is downstream of this hose - in the control valve assembly). I suspect the restriction of the 1/2" hose resulted in overpressurizing the pump. Anyway, I replaced it with the correct hose, much faster than the previous arrangement. [/QUOTE]
