Could not stand it went to big city got fittings, test results all at full throttle
call pump closest to counterweight pump #1
Call pump closest to bucket pump #2
Started unit and at full throttle pump #2 had 2k lbs, hit boom up an pressure drop to 1000lbs at boom up max, no pump noise
and pump #1 had 900lbs, as boom went up it dropped ending at zero with full boom up,
So i shut it off and recorded results, restarted now pump @2 has right at 1000lbs and drops to 500lbs at full up, push boom down at half throttle unit goes up in air like old times,but when I do stick in/out or boom up/down i get slight slipper shoes sound just for split second, and real light, but pump #2 will not drop to zero like pump one, curl bucket in or out at stops gauge is zero and lugs motor, now will lug motor boom up/down--stick in/out, so do I have trash in valve or valve sticking? hooking gauges up at valve block not at pumps, have to go get on dozer before lose this job be back this evening
