this might not be the best place to ask this
question but since it is a hydraulic issue i
figured i might as well see what responses i get.
im trouble shooting the leveling blade on the
front of a cat cp433e compactor. the blade is slow
to raise at first and when the oil is warm wont go
up at all when its running at a low idle. high
idle it works fine. took the valves apart and
found nothing there. put in 2 new pressure relief
valves in. the steering works fine and uses the
same pump but there is a priority valve that
divides the outlet of the pump between the 2.
there is only 875-900 psi at the cylinder. no
visual leaks. over 2000psi at the steering side of
the priority valve (the only side with the test
port). could a week pump cause this? also if you
steer and try to raise the blade it will work.
