Replacing centrifugal switch of SawStop tablesaw motor
Hi
recently, I puchased a used SawStop table saw with a 240V 3H.P. motor.
The saw whent underwater for an hour the day before carrying it.
So adter carry it, I dismantle it to dry and clean every part. It was not plugged at the time of being submurged. I clean with alcool avery electronic board; I unmount the motor and opened it. While opening the motor, I damaged the centrifulgal switch, In fact if you need to replace the rear bearing, you cannot do it without damage that switch.
I also noted that the 45uF 350V capacitor had a bulge. So I ordered the capacitor and the switch from SawStop; and discover the switch for that motor was unvaillable and you had to replace the motor at the cost of 550$.
I ordered the capacitor and found on Amazon a 19 mm identical centrifugal switch at less than 10$.
The way the switch is assembled to the rear bell housing but the hole thrue is smaller than the bearing; it makes mounting the bearing in reverse order than normal.
On second figure, see the bearing pressed into the bell housing.
On the third figure, see the switch fastened to the bell housing in front of the bearing.
Then I press the whole assembly on the motor shaft.
The tablesaw in running fine.
If this can help sommebody.

It's annoying that it's hard to service the motor without damaging the internals. I've changed the bearings on a couple of motors in the past and have been lucky enough not to have this issue.
Nice work. Daring endeavor.
Thanks for sharing. It's good to know this down the road for sure.
Congrats on the result. How did your saw wind up a submarine? It sounds like you bought it dry.
Hi, I purchased it dry, but we had a record rain and the saw was located in garage under the house; the garage door openned under the pressure of the accumulated water.
I took it the day after and rush to clean it. The seller reduced the price.
It's interesting that the SS cabinet saws are hitting the used market. If you'd share info on price, age, and condition prior to the swim I'm sure many are curious. Also, was the seller aging out of the hobby or just making a change to his setup? Thanks for any & all...
