642B BOBCAT MYSTERY

[gfrye]

CAN ANYONE OFFER ANY SUGGESTIONS? ALL HAD BEEN WORKING WELL. DURING ROUTINE MAINTAINENCE, I LIFTED THE CAGE AND PRESSURED WASHED ALL OVER. TWO DAYS LATER, I START TO USE IT AND NOW THE BUCKET/LIFT HYDRAULICS DO NOT WORK CORRECTLY. THE LIFT WILL GO UP SLOW BUT ONLY SO FAR AND ONLY IF YOU FIND THE RIGHT SPOT ON THE PEDAL. IT WILL NOT COME DOWN UNTIL YOU SHUT IT DOWN. THEN, IT WILL EVENTUALLY COME DOWN WITH THE PEDAL. THE BUCKET WILL TILT FORWARD ONLY (SUPER SLOW AND ONLY IF YOU FIND THE RIGHT SPOT ON THE PEDAL). IT WILL NOT RETRACT UNLESS SHUT DOWN. ALL LINKAGE IS FREE. I CAN SEE THE VALVE SPOOLS MOVE IN AND OUT. FLUID LEVEL IS CORRECT. I'VE LOOKED AND LOOKED TO SEE IF SOMETHING CAME LOOSE. I CAN SEE NOTHING. THE ONLY THING DIFFERENT IS THE WASH JOB. ANYONE HAVE ANY IDEAS?

Just FYI, if you do not use the aux hydraulics often, you can insert a pin under the cab so the aux hydraulics will not engage.
I have done the same thing with my 642.
