Power Steering stopped on my 460 Utility

Butch WI · Aug 1, 2010

Two days ago While cutting hay with the 460 u the hyd pump started to whine like there was no oil in the system even when I didn't use the hydraulics, then it would stop on its own. I finished the 20 minutes of mowing I had left with the whining happening about 4 more times. My power steering became intermintent but I still had some. I went and changed the Hyd filter and fluid. The round metal screen on the filter was completely blocked with what looked like the orange\red paint found on the inside of the transmission. I changed the filter, cleaned the screen, put in new oil (2 gallons over the full plug), jacked the front end to cycle the oil out of the steering (per the I & T manual) It seemed to be steering good. When I took the jack out it steers hard...as if there is no help from the pump. Am I missing something like cracking a line somewhere to bleed it? I have good hydraulic function of the 2pt. and remotes. I have to rake and bale hay and the field field is hexagonal in shape (lots of turning!)

Thanks

As the power steering has a seperate hyd pump mounted piggy back on main pump, it may not be primed. I don't think there is a plug strictly for power steering on the pump moounting plate but if there are two plugs one is for steering. You can just take that out to see if it is primed. If no plug,loosen line that goes into steering control or take line off at pump mount. The reason the screen on filter was plugged is because filter was plugged and that screen is a bypass valve for filter. Your system may be overheating causing paint to loosen or it may have done so previously and is still picking up remaining paint or paint just loosened from age , moisture etc.
