so the idea is to fit it in the tube, past the oil seal to get it jammed in..you dont smash it in...you get it in so it becomes jammed.
you turn the hex..if it spins...just tap it in a bit more to get it some the cylinder doesn't spin...took me about 3 taps to get it jammed in...
once it is in tight..try to turn hex by holding handle etc...and it comes undone..as they are not really tight in there...
take bolt off with fingers...pull out broom...
