belarus 570 hydraulics

Duckhunt · Oct 14, 2015

I have a Belarus 570 that after lifting something heavy (1000 +lbs) on the 3pt I hear what I believe to be the pressure relief valve squiling. If I slight lower the 3pt it will stop for 30 sec or so and then start back. If this does sound correct where is the pressure relief valve on the 570 and how do you clean it? Thanks For the help

On the 3 lever hydraulic main control valve, relief valve is on top right of valve. Thinking a little about the problem, maybe the pump for some reason is dead heading, thus the relief blowing. Could be caused by the unloader valve sticking or damaged. That valve is located on the left side of control valve under a 2 bolt cover.

Thanks for the help. I think I found the control valve. Is it to the rear of the hydraulic resavour . If so I don't see how to get to the top to check as it is just below the cab floor just under the dash? Am I looking in the correct place or is there a trick to get to it?

Been a few years since I sold my 562M, so can't go and look. You are looking in the correct place. Any removal panels in that area?

Thanks vapet, I'll look and see if I can find a way in this weekend when I'm down there. There has to be a way in there

Those valves maybe on bottom of valve. Been playing with a 420 valve and they are on top. Same valve but mounted different.
