20 Most Recent Delta 14-651 - Hollow Chisel Bench Mortising Machine, 1/2 hp, 1725 rpm, 120V, 0-1/2in. Capacity Questions & Answers

It's possible that the variable speed control may be the issue with your Delta 23-197 grinder. However, before attempting to bypass it, there are a few other things you can check. First, make sure that the grinder is properly plugged in and that the power outlet is functioning correctly. Check the power cord and make sure that there are no cuts or breaks in the cord. Next, check the switch and make sure that it is properly engaged. If the switch is faulty, it may need to be replaced. You can also check the brushes on the motor to see if they are worn out or damaged. If the brushes are worn out, they will need to be replaced. If none of these troubleshooting steps resolve the issue, it may be possible to bypass the variable speed control. However, this is not recommended unless you have experience with electrical wiring and understand the risks involved. If you do decide to bypass the variable speed control, you will need to identify the wiring that controls the speed control and connect the wires together to bypass the control. However, keep in mind that this will result in the grinder running at full speed all the time and may shorten the life of the motor. It's always best to have a qualified electrician or technician perform any electrical modifications to your tools.

I have used a double-ended bench grinder for years with only a single wire brush, without problems.

Hold (or lock) the grinding wheel on the other side if loose or lock because the locking direction is the same direction and don,t forget to ringing (sound-check -like a tuning fork) the stone if you replace it with a new one The risk is small but safety first

• there is also an
• centrifugal circuit inside one- side of the motor electricfield (not in the spare parts to see or order) that could have a problem but first measure the capacitor
• There are no brushes used its an induction motor. with start capacitor and an centrifugal switch. that was when you give a swing to the grinder the capacitor you needed has an 8 or 10 microfarrad 250 volt AC to start i think but be shure the start centrifugal is in good order and the capacitor together.

On a bench grinder the wheels turn towards you. This means the grinding wheel on the right side, has a right and nut, and the left side has a left handed nut. If you're trying to remove the left side turn the nut counter-clockwise

Unplug it first, if you like your skin. Use a wrench on the nut, and hang onto the wheel with one bare hand while you turn the nut in the same direction as the wheel normally spins. If you have a lot of difficulty doing that, jam the wheel with a piece of wood.

You need to check if the cost of the shaft will be too much and whether it makes sense. You have not indicated the reason for changing the shaft, if there is damage e it can be mended in most cases with the help of a machine shop.So check cost with replacement before you attempt.

first mark the caps so that when you reassemble they will align properly, Next get a small screwdriver and GENTLY pry the cap apart. One end probably has a rotating switch with wires coming from it so be careful. When reassembling you can use a small piece of wood to tap the end bells back into place.

It should take a standard grinding wheel, available at almost any hardware store.

It sounds like the capacitator might be bad or the starter windings. What you can try and BE CAREFUL is turn the switch on and spin the wheel by hand in direction it will be running to see if starts. Again BE CAREFUL

The new part number is 901912. You will have to contact a Dewalt service center to see if they can rustle one up for you. They are no longer available directly from Dewaltservicenet.com but you may get lucky contacting a service center.

I would take a look at the wheels or wire brush before I went any further. Then I would remove both and just run the grinder to see if still vibrates. But usually one or both of the wheels are out of round.

depends on condition and what comes with it. generally starts at $500 in good shape and up to 850 if excellent with many extras (chucks, rests, knurling attach, faceplates, etc) Also, check for accuracy...

Yes all the tool places say discontinued. Yes, bypass it, but make sure you don't overwork the grinder. https://www.google.com/search?q=2610904741 ..

Out of warranty ... time for a replacement machine.I would choose a different make. Assuming the batery is not the fault.

DIRTY CONTACTS POSSIBLY

Size for size and component value identical on replacement. Fit the correct part.

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

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.
