Can’t wait for the pictures, Charles !!

By the way ….. I wanted to get a “before and after” to see how much difference it makes, replacing my motor bearings.

With NOTHING on the arbor … the motor spins down to a full stop in 1.25 seconds … from the time I flip the switch OFF.

Once I replace the bearings, I’ll do the timing again.

May want to check yours, because … even though they’re different, it might give you an idea of what kind of shape your bearings are in !

mine spins for a while after shut off. Like probably 10 seconds. I think that might actually be a bad thing though. I think it means there isn’t enough grease. I’ll be really interested to see how long yours spins after replacing the bearings. My guess is that anything more OR less might mean that things aren’t working quite right.

1.25 seconds does seem pretty short (but I don’t know for sure) for a saw that doesn’t have an electronic break. I think your choice to change the bearings is probably smart.

HokieMojo: is that with nothing on the arbor ???

Hm. Interesting.

Rather than the electronic “dynamic” brake that a few of these DID have, mine has what’s known as the “viscosity broke down, and metal shavings turned the original grease into an abrasive sludge” brake.

Yeah. You’re jealous. I know ;-)

I did some actual woodworking, today, instead of working on the saw (what WAS I thinking ?!?), but … probably Tuesday, I’ll crack ‘er open, and get to changing out all the bearings.

Will report back.

If you know how to service bearings (and if they ARE serviceable), it’s NOT difficult to rebuild bearings, clean up everything, and either re-install the existing balls, with new grease, or—safer bet—replace the balls. As a home bike wrench, I actually have a few different sizes. When I bought them, I bought tighter tolerances than OEM.

So … you COULD go that way, if you were so inclined.

Thanks much, Dennis ! I’m probably only a month away from cutting something (other than myself), at the pace I move :-)

I must have read too fast. That was with a blade. I couldn’t tell you about without because my saw didn’t come with a wrench. The only way I was able to get the blade off was to put the blade in a clamp while the motor was removed from the carriage and remove the arbor nut (I did that today). I don’t know how I’m going to do the blade changes in the future, but I’ve been researching that as well. I hear bike wrenches might be a good solution.
