A BIG "DOH!!"

Look like fan blades to me! Just how DID that screw get in there? Hhhhmmmmmm?

Does sorta look like the remains of a cooling fan, doesn't it? That'd be my first guess.

Anyhoo, did that screw fall into your router? The plastic bits seem a tad too curved and large to be fan parts but ya just can't tell these days.

How are the vibrations? I'm sure you'd feel a distinct change with that much mass removed from the rotating bits...

Larry,

The on-line manual for that fan is item 1B Part #875931 but it "looks" to be a stamped metal fan. But seeing as how there are no other fans listed in the parts breakdown - that must be it. Shouldn't be difficult at all to replace it and depending on how many hours are on it, you may want to replace the brushes also.

Yes that deck screw was found inside the router along with the plastic pieces plus several pieces of wood. I was able to just dump the stuff out. With the router mounted in the table, anything falling through the bit hole could end up inside the router.....

I can't be sure just when the screw fell in and trashed the fins....with my ear muffs on I didn't really notice anything. No real vibration etc.

Thanks Bob...when I get a little time I'll dig out my owners manual and pull the router apart. I'll order that part 1B shortly. The router has less than

Could they be the end of a Shop Vac hose? My router broke off some of mine when I got it too close to the bit. They look a bit large for the cooling fan for something the size of a router.

I have ,since posting that picture , shaken 3 more plastic fins out of the housing. There is still something else inside there that sounds like another piece of plastic when the router starts up. I was asking if someone, with the same router, could look down into the bit end of the housing and see if they could see a black plastic fan in there. I'll go by the Home Depot today and take a look at one of their display routers.

You sure it's a router and not a Buick 8?

There is ... no doubt about it. Hard to tell if it is plastic, but it is definitely a multi-finned cooling fan.
