Expert's Assistant chatimg
Customer: Hi, I have a cat 246b skid steer. ALL implements bleed/relax slowly when unit is running or off. Even the auxiliary circuit. If you attach a clamshell bucket it will start to get loose within 5 min. and you have to close it again.
JA: Hi there. Have you had issues with steering before? Have any error codes popped up?
Customer: If you lift the main bucket it will slowly drop 6 inches or so over 20 min. Running or not. Tilt will do the same.
JA: Can you confirm the make, model, and year of your car? Anything else you want the Mechanic to know before I connect you?
Customer: Its a caterpillar tractor

Hi there! Thank you for using Just Answer. My name is ***** ***** I'd like to try and help. Sorry to hear you are having issues but with my help I am hoping we can figure out a solution to your problem. I understand how frustrating it can be.

You will need to remove the hydraulic control valve and have it rebuilt. Sounds like some orings or seals and bad and are allowing internal leakage and leak down of your hydraulic circuit. Its a simple fix, but only for someone experienced in rebuilding hydraulic valves and remotes.

*Please note that an automatically generated offer to pay for premium service will appear during this chat, I have no control over these, thanks for your understanding*

Thank you, ***** ***** tell me what the control valve looks like or where it is exactly on the machine?

You would have to lift the cab to access them and it is the valve assembly attached to linkage from the foot/joystick controls. I do not have access to CAT parts books so I can only give you a generic location.
