bird,
This might help, I have a 787 BH on a TC29DA.
Disconnect the hose that runs forward to the right side of the engine and re-connect the one thats free in that spot. Then just disconnect the rear hose and that's it.
Before disconnecting any hoses, pull the pins and slip the hoe back till it's free of the tractor by setting it on the ground and driving forward. When I remove my BH I extend it all the way out as far of a reach as it will go. Set the bucket teeth and the frame of the BH on blocks. Do all this while still connected and adjust it with the outriggers to relieve the binding in the bracket under the tow bar. Then shut the engine off, wiggle the control handles to relieve pressure, and disconnect. Notice where the three point arms are so you can slip them back into the same area when you re-connect. Pull out and support the front of the arms.
