Front End Loader problem

???I have a 1995 Zetor 3320 with zetor 92 system loader with internal pump. My loader works sometimes and most of the time it is very slow and will barely lift with engine at high RPM's. The 3-p works fine. I replaced the safety relief valve on the pump and still not working. I have book coming for the 92 lift system and am curious as to what it could be?

What should I look for?

how have you adjusted the flow divider ? on the 5245 its a lever sticking out on the vertical floor part in front of the seat, right hand side. you can swing it over 180 degrees, controlling the flow, and redirecting between 3pt and external.
