Wing pin Removal Tool:
The Shadow wing pin tool that came with my B-D Shadow is a 440mm long 3/8″ steel rod, with a threaded end (3/8″ x 16 UNC). Weighs 840g, so you wouldn’t want to drop it on your toe! The hollow wing pin is a 265mm long 5/8″ diameter aluminium tube, with 5/8″ steel ends pressed into it. The lower end is threaded to fit ‘slide’ tool.
To remove the wing pin, slip the ‘slide’ tool right down inside the hollow wing pin and screw into the threads at the lower end. Repeatedly slide the weight upwards – each ‘impact’ helps draw the wing pin out. That’s kinder to the wing pin than bashing it out from below.
