I have a question about backhoe bleed down. The backhoe on my BX23S bleeds down ... if I don't put the pin in, it will be on the ground over night. My understanding is that this is not uncommon, if not actually normal behavior.
I did a test and disconnected all three hydraulic lines, and it still bled down. I haven't run any timing tests so I don't know if disconnecting the lines changes how fast it bleeds down.
It seems to me that the bleed down can either come from internal leakage within the main boom cylinder, or valve leakage. The boom cylinder is extending, so it wouldn't lock out if there was an internal leakage (thanks Dan).
If the boom bleeds down with the hydraulic lines disconnected, is this semi-direct evidence that there's internal cylinder leakage? If not, where else would the displaced fluid from the rod end be going?
Thanks!
