It is either the capacitor or the centrifugal switch. You can hear the centrifugal switch on some motors on start up.. It makes a clicking noise and then stops when the motor gets up to speed.

You should be able to pick up a start capacitor at any motor rebuild shop or a good electrical supply shop. Take the old one with you. Make sure that you short the contacts before trying to remove it, to avoid a potential shock.

Just disconnect the wires and arc across the capacitor contacts with a plastic handled screwdriver, it'll eliminate any remaining charge (if any) in the capacitor.

Could you be talking about this band saw or one like it, see picture. If so here is what I can tell you.

I used a friends before I bought the one pictured, and it did exactly as you described. I figured out that it was not the motor. Remove the belt an you will see it runs.

When I bought this saw I opened the gear box, brand new it had this mix of what looked like graphite and oil.. I mean gray slug like past. I literally had to scope the crap out, washed the box several times with lacquer thinner to remove the past. The second picture shows the update I made, along with redesigning the wheels so I could move the thing without it falling over, and some other little items to make cut true. It is a descent saw but does need some help to make it a worth while tool .

I have an older green HF version of the same saw... I actually returned one for exactly that problem (and a cracked casting) and when the second one did it also I figured that I'd fix it...

swapping the gear lube for something less sludge like helps, especially if you're having this problem in the cold, but the real problem is that the stock start capacitors really suck. Replacing them with a new one should fix it, I just added a second one, so I have 2x the the original capacitance (probably more like 1-1/2 since I'm sure that the original didn't have what it was rated at), and now it starts with authority (it might be a little too much, even the stock little motor has enough torque at start up to flex the mounting/adjusting plate).

www.useenco.com

Just search "bearing" and follow the guide. Cheapest and easiest place I know to get decent bearings, I have bought a bunch of them from these guys in various sizes and I am sure they have the ones you need.


BTW, they can probably get you anything else you might need for that saw since they sell their own model of the same one.


If you decide to order from Enco they have a code right now that will get you totally free shipping if the order is $25 or more.

Check an auto parts supplier, or there are even "bearing houses" in most major cities. Almost all bearings are standard sizes that can be looked up by the numbers on the side of the bearing, and usually if I need one or 2 I just get them from a local store, if I need more I've bought them by the tube, 10 at a time on ebay.
