I have a farmall 450 with power steering and have blown the pump seal out twice. This time we have had the factory flow divider rebuilt which did not solve the problem the pump still gets hot and is on constant pressure. We drilled the orfice out to.40 over with no relief from that either and we have installed a different rear remote valve with no change. The only way the pump doesn't get hot is to put the outside rear remote lever ahead to relieve the pressure . We have tried adjusting the single and double valves in the other 2 remotes which some have said is where there problems were but no change . Looking for any suggestions as to what it may be causing the pump to get hot and stay on presssure. Thanks
