My Dewalt router started squeaking a few days ago. Anyone else have the same problem? What did you do about it? Thanks.

Please tell us, Is it when your routing into something, or when it is winding down, Or is it when plunging. It could be something rubbing on the commutator,or ? It is hard to tell. without a little explaining Please put your mane and location 0n the profile, It you lived nearby, i could hear it;)

Hello Ivan, Thank you. If you Are checking a bearing, it should also get warmer than the others, Jim could be correct with the bearing, but, i would say that the bearing would squeak when spinning under no load. Does it do it when running at slower rpm? With it not starting to squeak until electric stops flowing, i would be quicker to say that a wire touches an object very close, or something that reacts to no electricity, that is the culprit. It is just an idea, but strange things happen. Hope that it helps :)

WD-40 is fine as a diagnostic tool, squirt it and the noise goes away you are pretty sure that's where the problem is. Fix would be to replace the bearing. I have an old, 25+, shop vac that does that. I suspect the bottom bearing. The magnetic field stops and the armature drops against the bearing putting a side load on. My shop vac is a wet/dry and has been used as such so all the bolts are all corroded up. Waiting for it to die, then replace it.
bigdogs router.. bearings are available at ereplacement parts, both for less than $30. I would replace both. I thought there may be a thrust bushing in there put the parts explode didn't show one. :)

Hi Guys

" It squeaks as soon as I turn it off and it's winding down."

My RAS will do the same from time to time,,it comes from saw dust in the motor :)

As Bj has pointed out, dust alone inside the motor can cause a similar problem. Use some air, blow out the router, then, check the bearings. WD-40 isn't a lube, nor is it a true "quick band-aid" of a fix. It may be wise to just replace the bearings. I'm not a fan of DeWalt due to a similar situation.

Hi Ivan

Now that I think about it,, on my RAS has not made a sound once I put my router plate back on,,It has a spring/waver washers on the out board side of the motor and when I had the plate off I put some grease on it and put it back into place..not a squeak,, you may have the same type of washer in your router..

The washer looked like the one below...the RAS is a DeWalt also

This washer stops end float as the manufacturing error to machine the armature and casing of the motor is less of a problem. It doesn't stop the bearing spinning in the housing. This is achieved with the "friction fit" of the bearing on it's (the bearings) outer ring. The washer presses on the outer ring and the base of the housing
