I have a couple DeWalt DW618 routers that are 8-10 years old and have seen heavy use. They both started acting up in the same way. During a cut, the speed changes erratically. Most repair shops would recommend replacing the router because a new speed control unit is the same cost as a whole new router.

I pulled the carbon brushes and they were all chipped away. Replacing the brushes totally fixed one of the routers. No more stalling under load. The repairs had no effect on the other (older) router. But, the brushes were cheap and worth a try. I’ll be replacing that motor.

I’d say if anyone has similar router problems, inspect and replace the brushes.

Remove cap with four torx drive screws.

Lift cap off motor.

Pull retaining spring to the side with a small flat screwdriver.

Replace carbon brushes with new ones. Repeat process on the other side.

Cool. Great info. VS can be asking for problems, and I usually try to steer clear, but sometimes its necessary, like on larger routers…

I hope you’re able to find a motor replacement. I looked for a motor replacement for my Milwaukee, and they only sold the router in a whole kit at the time.

Hey Pete,
You make a good point. With the Dewalt the fixed base kit is usually the same price or cheaper than just the motor, so I’ll get that.

Have a good one.
