Have an old sears craftsman 1/4 hp grinder model

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

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. older-sears-bench-grinder-wont-run-1-3-z1zi3msqm0xxzvze3v341n5r-4-0.jpg Klixon 2CR relays are no longer available.You may find a suitable replacement here: http://www.herbach.com/Merchant2/merchant.mv?Screen=PROD&Store_Code=HAR&Product_

How do I get a manual for 55-3584-2 bench grinder

Considering how potentially dangerous grinding machines and wheels are and how much safety legislation exists about their maintenance, adjustment and use, a great deal of printed matter exists about these things and the wide range and selection of wheel material. You should have no bother finding useful information, fortunately bench grinders are extremely similar to each other... https://images.homedepot-static.com/catalog/pdfimages/b6/b64b39fb-6d42-4fec-a274-76bbd950e6d8.pdf

I have a Buffalo Model B-8 bench grinder and am looking for a wire wheel attachment. This grinder was purchased in 1982. Not finding comparable parts anywhere.

A wire wheel is bought from the same sort of supplier as you would buy a grinding wheel. The dimensions of the wire wheel should be similar to the grinding wheel it replaces, though the centre hole is usually larger and should be fitted and mounted with the correct size plastic bushes and steel retaining washers. The guard and the tool rest should not be used with a wire wheel for safety and of course there should be a hook nearby to hang a pair of safety goggles... Bear in mind, in a commercial environment, local legislation could exist that means only a suitably qualified and registered person is allowed to maintain/adjust a grinder as in the UK and Europe.

Un plugged the wires from the switch and do not

Mmmm... that's a little more complicated. If you have a continuity / resistance meter, we can noodle it out, though. First, are the two white wires the ONLY wires coming from the motor? I suspect they are - that's not in conformance with any accepted color code, but it'll work. For the rest of this, I'll assume that the two white wires are the only ones from the motor. You'll need to meter the switch itself, with no wires connected to it. In the OFF position, you shouldn't find continuity between any of the four switch contacts. In the ON position, you should find continuity between two pairs of contacts. The black wire from the power cord should go to ONE of the two switch contacts in a pair that have continuity with the switch turned ON. One (either) of the white wires from the motor should go to the other switch contact IN THAT PAIR. That leaves you with one more pair that has continuity with the switch turned ON. The white wire from the power cord goes to one of those, and the second white wire from the motor goes to the other one. When you have it all wired up, plug it in & turn it on. If it's not right, it should immediately pop your circuit breaker. If it IS right, it should run fine. If it pops your circuit breaker, open it back up and swap one wire from the power cord and one wire from the motor.

I have a buffalo 6 inch dual wheel bench grinder cord and off on switch are missing how do i hook up the grinder is old and has 4 wires

Usually, 4 wires are multi-directional neutral and earth are usually colours the other 2 are both live and would need to go through a switch. you can of course put the other live in a cover and just use one live wired as usual into a plug. Make sure the spare wire is well protected ie in a jb with plenty of tape around it

I didn't find a manual when I searched. A similar model for sale shows a vender site, where you might ask the question of whether a manual could be provided to you. https://www.amazon.com/sp?_encoding=UTF8&asin=B0057PLTL2&isAmazonFulfilled=0&isCBA=&marketplaceID=ATVPDKIKX0DER&orderID=&seller=A1DXFJTFV58TSS&tab=&vasStoreID=
