   Afternoon...

   You say you are "sure" the squeak is in the motor! I have to assume that you took the belt off the pulley and ran the motor with no belt and you got a squeak. If so... sounds like a bearing on the shaft.

   If you haven't removed the belt.. I would to be absolutely sure that is the motor. Not doubting you but I have seen many cases of where it sounds like where a noise is coming from is deceptive as sounds bounce and relay. That makes it very difficult to determine where they are really hidden sometimes.

   Regards...

   If the sound is definitely in the motor, the source is most likely coming from the centrifugal switch which has a couple of parts that rub when the motor is slowing down.  The rubbing parts are usually made from a low friction plastic so they shouldn't squeak, but it happens some times.  If the saw doesn't get used a lot, and if the sound doesn't seem to be getting worse, you can safely ignore it with little risk that the switch will fail anytime soon, if ever.  If you want to get at the switch, the motor will have to be disassembled.

   The only other halfway likely source of squeaking is the rubber seals of the ball bearings.  You can put a drop of a light oil on the shaft where it comes out of the motor on either, or both ends, of the motor to get a bit of lubrication on the outer seals.  Getting oil on the inner seals would require opening up the motor.  Again, if the motor isn't seeing a lot of use you can safely ignore the sound if it is coming from the bearing seals.

   Motor squeek ??  I just helped a customer find His squeek.  Try this,  Back off all of the blade guide bearings well away from the blade and see what happens.   It is amazing how far that squeek travels.

   Afternoon Bruce...

   That was my initial thought and why I ask if he was absolutely "sure" it was in the motor? If the squeak is not isolated to the motor, I'll put my money on your guess as most BS's will squeak if the bearing have been set at too tight a tolerance, especially the rear ones.
