Looking for a on/off switch for a craftsman 8" bench grinder


Sears Craftsman is usually easy as Sears Parts Direct has diagrams and part numbers.
However your switch number 31919063033 is no longer available. I would suggest checking out online places like Digikey or Newark for a switch that will work for you. As long as the Voltage, amperage and number of poles and will fit in the space provided you should be OK.

I have a 1/3 hp motor with a capacitor. There are four motor leads coming out of motor, the capacitor is mounted in the wiring box. This motor does not have a centrifugal switch, to isolate the capacitor...


I am in the process of replacing a capacitor on a Craftsman 6 in 1/3 grinder, 2.8 amp, single phase, 110v. Not sure on the centrifugal switch. model 319.190621, ser B9530. When I took the old one out the black wire from the capacitor went to the cluster of back wires (in my case 3) in the wire nut. The blue wire from the grinder went to red wire from the capacitor in a wire nut. Hope that helps you....

Maybe you can help me... the specs on the capacitor burned off when it failed. Can you tell me what the capacitor specs are on yours?

I need a replacement switch for a craftsman 1/2 HP bench grinder model#397.19441. I have no owners manual or parts list. This grinder is several years old.


this switch is no longer available from Sears, so I suggest making a wiring drawing and taking the switch to a local electrical supply house and try matching it up with a replacement. It seems to be a simple on/off type switch and I would think that you should have no problem. Let me know if you do and give me the information on the switch and I will try some other sites I know.

Have an old sears craftsman 1/4 hp grinder model 397.19501 wires have been disconnected. I want to rewire and test. Does anyone know how to connect the wires? There are 2 copper tabs under the on/off...


the two copper tabs under the on off switch are to break the power source.connect incoming power to one of these(black) then a short piece of wire from the other tab under switch to one of the three tabs under plate that is marked hot or l1 is probably #2 but you need to be sure. the white is the nuetral or l2 which is most likely #3 and the green is the ground most likely #4 I would definately look online for a wiring diagram to be sure if they are not marked with L1 L2 and GND

Need manual for craftsman bench grinder model # 257.191300. misplaced other one. hope you can help. mike


Mike
Not sure what was happening when the previous reply was created, but the owners manual is part number 211260001 $7.99 at SearsPartsDirect.com

That said, I'm staring at my own copy of the the owners manual and I can't really see why you would want to pay for one. The only really useful information is the parts diagram which is online at SearsPartsDirect.com. The rest is generic grinder information (support workpiece, select proper wheel, etc.) and CYA (always wear gloves and eye protection, don't remopve safety guards, don't use damaged wheels, don't stick your finger in the light socket, don't cross the steet in the middle of the block, etc.)

Older sears bench grinder wont run 1/3 hp model 397 19581


I know this is an old post, but maybe it will help others looking for information.

I have the Craftsman 1/3-HP grinder models: 397.19580 & 397.19581.

They are Split-Phase single voltage (115 V), and use a Klixon start-up current style relay - 2CR14-224.

The relay is normally open. When the large starting current in the main/run winding circuit is sensed by the the relay coil (term 3 & 4) which is in series with the main winding, the relay contacts close (term 2 & 4).

The one end of the start-up winding is connected to the main coil's BLK wire in the coil pack.

When the relay contacts close the start-up winding is energized. The start-up coil is used to provide a boost to over-come the resting inertia of the rotor.

Once the rotor reaches between 65% - 75% of operating speed, the current through the main winding circuit is reduced to the point that the relay coil cannot over come the return-springs force, acting on the relay contact arm. With the contacts open, the start-up winding is no longer energized.

This should take about 2-3 seconds, if the relay malfunctions, the high current through the start-up windings (thin wires) may be damaged.

Here is a diagram I have made.

Klixon 2CR relays are no longer available.
