2-105 hydraulic

[rrlund]

Well...I mentioned below that I put a rebuilt pump on my 2-105 last week because the hydraulics were overheating. I cut hay this morning and after an hour, the light started blinking again. I let it cool off and went back after dinner. I went about 40 minutes this time. There's a Mennonite hydraulic shop a few miles away. I went over there and he said he'd come over tomorrow at 1 and take a look at it. There seems to be a pin hole in the suction hose between the filter and pump. He didn't have any inch and a quarter, so he told me to put a piece of inner tube and some clamps on it and try that. Didn't help. Don't just assume it's the pump if overheats is the lesson here. I'll let you know what he finds.

I have had three occasions now where guys had bought a new pump and the compensator was set higher than the main relief, and for whatever reason mechanic didnt know he had to set compensator, or maybe didnt even know how? One was a Agco dealer. The other issue I have seen is crap from the old pump that was indeed bad had gotten in to the main relief body holding relief open. As you probably know the prerequisite to installing a new pump nessitates cleaning out the valve bodys as pump flow goes directly there with no high pressure filter. Unlike most industrial applications of the same basic pump utilize a high pressure filter. When you think about it a fella should probably look at how hard it would be to plumb in a high pressure filter??

Thanks Tom. I'll pass all of this along when he gets here tomorrow.
