noise in hydraulic pump on 300U

Posted by Charlie M on September 21, 2006 at 09:24:27 from (65.37.82.45):

I asked this question a couple of weeks ago and didn't get too much response so I'll try again. The pump on my 300U has suddenly started making a combination grinding/vibrating noise for about 3 seconds after using the hydraulics and then it stops. When I first heard it the system was low on oil. I drained the system and refilled it and the noise is still there. Any ideas before I do my usual thing which is to spend money on the wrong thing. Could it be the relief valve sticking? I've got 2 valves (one is 2 pt hitch) and both do the same thing.
