Hello, anyone know what I did wrong when I reinstalled new parts for rear control lever & arm valve guide et al on 1994 B7100 HST D…Initial problem was broken bolt inside value cover caused rear hydraulic control arm to seize/stuck” so unable to activate 3 pt hitch. Bought & replaced new parts but I think when reinstalling the control valve assembly I must not have had the control arm, arm valve guide and or pin/spring on the spool positioned correctly because now upon startup the rear 3 point it automatically goes up and stays up causing the pump to howl..The lever control arm has no movement backwards ..just moves forward or straight up and movement of arm forward has no effect on rear 3 point hitch which stays all the ways up. The only way to get the rear 3 point arms to lower is to shut off the tractor. I’m thinking I have to reposition the arm value guide differently by moving the control arm in a certain position as I start the reinstall. Anyone out there that knows the proper positioning of the lever control arm/control valve guide onto that pin/spring and spool ? Should I have reinstalled with lever control arm in full forward position or full back position instead of straight up? Clearly the reinstall I did has caused the activation of the “lift” with no ability to shut it off (neutral lever control middle position)or lower
