I have a 2001 Bobcat 773 Turbo with hand controls. Recently the lift arms have been seeping down ~ 6-8 inches immediately after the arms are raised. It will seep 6-8 inches downward and then stop. What's more is that when I roll the left hand control outward to begin raising the arms again and they actually drop until I roll the control out even more and then it will rais the arms... then again as soon as I stop, they seep down another 6 - 8 inches over 5 - 10 seconds and stop. I've thought about the issue being a bad o-ring in the valvebody; however, I would think that the arms would seep down continously. (note: the arms will seep to the gound if left raised.... probaly drop a foot in 30 minutes). I've been told that there is a piston inside the lift cyclinders which go bad and can fluid to bypass which may cause this symptom too. I've also read where the actuators may need to be re-syncronized; however, everything had be working fine and I've been told that they rarely ever need to be re-syncronized... rather the actuators burn up. I hate to start guess at what to try to fix first. Any suggestions and/or ways to prove out any of these theories would be appreciated.
