Table saw motor hums but won’t run
This is the motor from my Grandfathers table saw which was handed down to me.
With the belt removed and giving the shaft a spin the motor runs but will not run with the belt engaged. Looking on YouTube it sounds the same as a motor with a faulty capacitor but there is no capacitor on the motor.
Is this something that could have a simple fault or is it likely that motor would need to be rewound.

If there is no capacitor maybe there should be one and it's missing.

Hi Bohdan
Saw was working fine up until a couple of years ago. I’ve had it for close to 20 years I suppose. Gradually got worse over time to the point it won’t start at all now.

Disregard the previous post. The motor is fitted with a centrifical starting switch. Either the switch is not closing when the motor is stationary or the starter winding is shot.
The switch may be simply not closing because of dirt buildup on the contacts (most likely) so you need to open the housing to see if there is any obstruction to the operation of the switch. The switch should be located on the motor on the end away from the pulley.
A possible repair may be to give the motor some very solid wacks to try and dislodge the dirt and loosen the switch mechanism.

The housing usually needs to be knocked off. It is a tight fit as it holds the bearing. The WD40 won't do any real harm but it also probably won't do any good. You need to get the cover off to see what's causing the problem as the switch may have started to disintegrate.
PS Make sure that you are unplugged while working on the motor.
PPS If you get it apart check the bearings while your at it. If not sure just replace them.

Cheers thanks for your help.
Will update once housings off, probably next weekend as we’re just about to do a camp oven roast and that requires the drinking of red wine
