Wish there was a way to replace that plastic. Stripped on mine.

Hi!

Is it possible to change just the plastic part where the brush screws in?

They did a really dumb thing and made a metal screw go in a plastic thread so of course, the plastic thread finally gave in.

The brush spindle gets replaced as part of the motor assembly.

Now I just need to find a good part # for the motor assembly. I'm replacing mine because of the worn out plastic spindle too.
