Hi. I have replaced all the boom dipper and bucket lines on my Bradco 8LD backhoe mounted on a B8200 HST. It has been a long time coming. Everything is re-connected and I am ready to get it working. Have the boom and dipper connected and on the tractor. All the lines had been drained and removed except for the swing cylinde.r I am preparing to bleed first the stabilizers, passing on the swing function as the dipper is at rest on the ground minus the bucket. I am thinking of bleeding boom, dipper, and bucket cylinders in that order. working from closest to furthest. I am also considering only attaching the anchor point of each cylinder and allowing the pistons to move under no load.. Any thoughts on this procedure with any recommendations? I am expecting the proccess to take awhile with constant checking of the fluid levels

You can bleed if you want to but the lines and cylinders will purge out the air as you cycle them a few time each, without doing anything before hooking everything up.

No bleed procedure required. Just use it and air gets pushed out. Maybe Jerky at first until enough fluid circulated to displace air.
