Fit my DWE402 Perfectly
It was an easy fix - especially with the correct part. This fit like a glove and was exactly the same as the other brush holder that i didn't replace.

Armature assembly burnt out for being plugged into a unmarked 240 outlet

Parts Used
Assembly was completed mainly from the rear of the grinder. When one side of housing is off, the next step is to take fan off on top of the armature assembly. I used a flat screw driver between blades and socket at the bottom end (caution of thin blades if brittle). Slide the armature into channel up to carbon brush. Using a flat screwdriver, pry up red Arm holding carbon brush and push assembly up until arm is seated by a fraction and do the other side. Regrease metal on metal contact on top, assemble and turn on power. Disassemble top and regrease and your good.

I opened the bottom half of the grinder, (it is in a clam shell configuration). I then removed the arms and brushes using a allen wrench and small screw driver.Then put the new ones in place. Replaced the bottom half the grinder to its original form. And bam I am done easy as pie!

Tools Used
Screwdriver, Pliers, Tiny star drive tips
When the brushes failed, the arms that hold them against the armature were damaged. They were held in with #4 star drive screws (TINY!!) which I initially thought were Allen screws, they were that hard to see (and very difficult to approach, being tucked in behind the motor fan). I broke the arm mount in disassembly but with a certain amount of force and the replacement case, I'm back in business. Should have removed the fan so I could see the mount screws with a magnifier (which is what I used) and would have saved the damaged mount/case and made a MUCH simpler repair.
