Depends what parts are needed. Spare parts for something that goes wrong so rarely can be difficult especially if the machine is imported. Some parts will be fairly universal and so fairly easy to obtain - nuts, flanges, abrasive wheels, bearings, capacitor (if fitted) and possibly even the switch and tool rests.

SOURCE: Bench Grinders Safety issues

Goggles or safety glasses need to be worn to protect the operator's eyes from the sparks and metal filings that result. Depending on the workpiece and time of exposure, hearing protection may also be required, the dust produced is also potentially hazardous. The toolrest (or workrest) should be mounted slightly below the center of the grinding wheel with less than 3 mm clearance from the wheel. This prevents the work from jamming between the toolrest and the wheel. Grinding wheels designed for steel should not be used for grinding softer metals, like aluminium. The soft metal gets lodged in the pores of the wheel and expand with the heat of grinding. This can dislodge pieces of the grinding wheel. Wire brushes require particular attention for the safety of the operator and bystanders as the metal wires may become dangerous projectiles as they could bind with the object being brushed and so throw it away with great energy. The machine needs to be securely mounted to a pillar or a bench to be used safely and effectively, often with an emergency stop switch or pedal fitted close by the machine, for use in emergencies.

Replacement should be simple. Just do a one for one hookup with the new part, after you unplug it first.

You just move the belt up or down for a ratio change.

SOURCE: bench grinder, 110/220?? wired up properly

LIKELY the capacitor which is usually in the base is bad.

The capacitor shifts the phase angle in one of the two windings which creates a pseudo rotating field to start rotation.

Your grinder is listed on page 3085 of the Grainger catalogue. The part number for the eyeshield is 00281.00 and the number for the lower eyeshield bracket is 00280.00. The right hand upper eyeshield bracket is number 25188.00 and the upper left hand bracket number is 25177.00. All of this can be ordered through Grainger at 1-800-323-0620. Marvin T.

I have an old Craftsman bench grinder that I got at an auction. I need a capacitor and the one on it has no markings. It is a 1hp model 319.19063. Sears Parts direct says that it is no longer available and...


this is a "Split-Phase"motor it uses only a run capacitor and a typical capacitance rated MFD rating will be between 80 and 290 MFD, go to www. grainger..com and they will have your part,and even if its an older unit and the model/serial/number is available take it with you & they will have a replacement capacitor available in the correct size/dimension/mfd/etc

No motor replacement for 152.217060 6 1/8 planer


You are correct, there is no replacement for part # OR90357, but if you have the original motor, I am sure that a local electric motor repair shop will be able to repair, or replace it. I'm confident that this is your best option at this point.

Cant get a on off switch anywhere co that maid it for wilton is out of business what a scam.


Repair parts have always been a problem.

See if you can get into the electrical area ... open the bench grinder from underneath ... tie the switch wires together ... put a regular wall switch on the electric line.

I hope it works for you.
