[QUOTE=WinDancer;508172]The motor in my older [maybe 10 years] Delta 10 inch drill press will only work if you start it spinning by hand.
The motor is a sealed unit with no parts available.
It has less that 10 hour total use.
My experience [very limited] tells me that this is a capacitor problem.
Took the motor to a local repair shop, tested the capacitor and it is bad.
The tool repair shop would not sell me a capacitor without a part number.

Delta will not help in any way.

Will anyone give me a capacitor number that I can order to try?

Thanks if it works, oh, well, if it doesn't.

My only option right now is to trash the drill press.


On the capactoor these number on the side buy lose to 5% -/+ will work.,!!!!!! Same size & volts also

Dave, that would be silly. Hang in there, you'll get your answer.
You just need a start capacitor for a 120v 1/4 hp motor.
They're common as dirt.

I had the same condition with the motor on my old mill. We worked it out in a very short time & solved it for just a few bucks.

Well I usually use 5mf caps on Furnace motors that size if that helps any .

I collect capacitors and when one goes bad I find one that is about the same size physically and put in in and have never had a problem. I know this is not the right way to do it but it works for me. To test a capacitor it is best to have a analog meter set to read ohms, put a lead on each connector and the meter should read high resistance and slowly go to to zero, reverse the leads and the same thing should happen. If it is open it is bad. A digital meter will also work.

Well, best would be a digital meter with a capacitance setting. I've tested several that fail, but still provide some amount of steady capacitance, but only 20-50% of what it should be.

In the air conditioning world, a motor that size could use anywhere from 3 uF - 15 uF, with 5 uF and 7.5 uF being the most common.

Learn something every day. I assumed that the diode checker on a digital was just a continuity check with a bell.

Diode tester and capacitance tester are two different settings, the latter is more rare, often only found on testers designed for field technicians.

This is mine: http://fieldpiece.com/clamp-meters/sc66

Even my $300 Ideal electrician's digital multimeter doesn't do capacitance.

my fluke 179? does capacitance and it cost me $135. On ebay but with wires and box I'm up to $300.

Lu47Dan:
If he has two [I have two of this model drill press] of them that he thinks will work I would be thrilled to send the money for them and the shipping and a couple bucks for gas. If you have PayPal that would work, if not, snail mail if you send me your mailing address Or I can call him direct and order them, whatever works best for you. And if they end up not working at least we gave it a shot.

Thank you all for the info! Having the drill press working correctly would save me throwing it out.

Thanks!
Dave
Dave, I will call him in the morning and see what he can do, if he can help out, I will send them to you in flat rate envelope.
Dan.
