Default Porter Cable runs hot

I have a PC 890 that I bought a few years back and use exclusively for table routing. Recently, the tool runs so hot after fifteen minutes or so that it is uncomfortable to change the bit. I tried blowing it out, seemed pretty clean and still runs hot. What is wrong?

Hi Bill - my guess would be a bearing went out on you. Since you have been running esclusively in the table, I'm thinking items 14 & 15 on this explode.

If I were going to change those, I would also change item 24 and the brushes.
Good Luck

The problem with experience is I usually get it immediately after I need it.

Fishlore, I agree with the other two RF guys, but while your at it, you might get some spray cleaner for electrical components and clean the field and the armature. Also, use some fine emery cloth and make sure the contact point for the brushes is well cleanedon the armature also.

Bill, I agree with all above coments, the bearings are the most common defective parts to make a router get that hot. They are relativity easy to replace and sure make an older router perform like new especialy after a good cleaning and brush replacement. A screwdriver, small puller and impact are all the tools you will likely need. V/R Robbie
