Yea sorry, should have mentioned I am across the pond.
This forum is the best one I found on the internet for repairing these machines, so I really appreciate the help.
I had assumed that the brush motor head was dead because I was getting 160V going into the head, but the bars did not spin. Plus l like I posted before, the bar had been sheared from the outside screw.
I will try to completely disassemble the head and try to double check.
