1997 753 hydraulic problem

[tjdeerefan]

Hey guys. Just replaced 2 leaking hydraulic lines on one side of the boom. Filled the hydraulic oil res. and then started it up. The boom will raise but it is noisy. The bucket will not raise or lower. The boom will not lower. Was working fine before I changed the lines (although it was leaking) any help would be appreciated.

I assume its a jittery noise, it sounds like air. It still should lift though. Try letting it sit over night then try again the next day, it allows the air bubbles to settle out and helps remove the air from the system.
How are your BICS lights? are they all lit? it sounds like its locking you out of the lift/tilt operations as you say it will not lift or lower.

boom will lift. All bics lights are lit. I will let sit overnight and try tomorrow. Thanks for the reply.
