B phase is bad? are you just saying that the center pipe is the problem ?.
..if this is in the slab pour some lube into the pipe at both ends..then pull only one cable at a time. pick a cable, serve on a clove hitch and several half hitches close to the pipe take the free end of the cable and make a loop in it to keep the rope from flying off..now the hard part.
someone will have to make sure the now looped cable stays looped, use an open, gloved, hand to do this, slowly put pressure on the pulling rope with the tugger, release the pressure, re-apply pressure, release ..until the cable starts to move..keep the loop closed..DO NOT STAND in front of the rope.be sure you are to the side ..pull the cable out as straight as possible. make sure that everyone involved is on the same page !
You may only need to rig the tugger once, after the first cable is out the others might just come out by hand
