Slow & didn't start
Removed the 2 phillips end cap screws to access the brushes. They simply pull out to the holder after I took a pick and held the brush spring off to the side. When replacing the holder you have to separate the two halves of the handle. Not a big job. Just make sure you line up the steel field that the armature turns in. It has a notch in it that has to line up with the one in the handle housing. If you don't do this you can't get the housings completely together and wonder why. This happened to me. Also make sure the detent springs for the High/Low don't fall out when putting the two halves together. Otherwise it was a simple repair. I have done 2 drills so far in our business and plan to get more parts to do more. Parts are identical to the original and are in Makita labeled packaging. Also great pricing.

Makita drill got so hot that plastic melted and hung up one of the brushes, and died.
You can follow instructions on line but a few notes here.
Take all screws out to split the blue handle. slowly split the handle.
Hold the motor parts with hands to remove (only enough) old brush holder,
Remove the trigger to disconnect the old wires and connect new wires.
(Make sure the wires clip on little holders.)
Reassemble handle carefully and see that it sits perfect together.
Install new brushes after put together. use little hook tool to hold up spring to slide in brush.

I could do it within 30 min now, but I took a lot of time to have it repaired correctly

    First time buying from this website and I have to say that's amazing. I just pay $15.00 for the parts that I needed and I was able to fix my drill, It's working like the first day.
