Topic tags/keywords: craftsman router part

I have a Craftsman router model 9 1748. It’s identical to the router shown in Brandon W’s response to the forum here “What Is Your Favorite Router and Why?” <http: />. While picking off a piece of plastic protecting a new router bit, a small piece of it went flying. Stupidly, I was doing this right over the table mounted router. There was a possibility that the piece might have landed in the router. Long story short, I ended up taking apart the router looking for this piece. First off was the black housing followed by the section holding the wires, brushes, shaft, etc. After the second section was off, I noticed a small (3/4” diameter approx) retaining type ring of some sort laying on the workbench. This ring is flat on one side and has 4 raised arm type things on the other side. Problem: I don’t know where this goes and which side is up. The worthless manual doesn’t even show this part anywhere. Can anybody tell me where and how this piece goes? Sure would appreciate it because my entire project is at a complete standstill. Thanks!

Got the model # wrong (wasn’t w/ me when I posted this). Correct info is Craftsman model 315.17480. Sorry about that.

By your description of the part it sounds like a retaining washer used to hold bearings and/or shafts in place.

Look at the end of the router shaft that is under the plastic cover and see if you can see the thrust bearing and its retaining washer which is usually covered by a piece of felt to keep out dust and aid in lubrication.

If the washer is missing then I assume that is what you have. Check to see if it looks like it could fit but push it in carefully as not to damage the bearing. The fingers should grab the casting around the bearing.

If the washer is there, I do not know where else it could have come from, or more importantly why did it fall out.
