Hi. Yeah i came right. Proportional valve faulty.
Fault code 474 and 473 popping up now and then ? Do you know what it is ?
My issue inded up being a bad proportional lowering solenoid valve. Replaced it, calibrated valve hydraulics and everything was good after that. Which lowering valve did you replace? Keep in mind the calibration procedures must be followed correctly.. Forks tilted up, p1 lowering speed @ 90, 1500lbs minimum.
hi. I have the same problem on a crown rr 5700. did not lower at all. replaced the lowering valve. it lowers now but very fast. the velocity fuse comes in to play and only the free lift comes done. what have you done ?
