Need to know what start and run capacitors to use in my century magnetek 3 ho motor that goes on my sanborn Blackmax compressor

SOURCE: change from 220v to 110v on air compressor

I can't blame you for askig, but here's my response. 5 HP is 3750 running watts. or about 35 amps at 110 volts and it would take somewhere around 50 amps to start it provided the motor could even be wired for 110 which I don't believe it can and for that exact reason. I'm sorry, but it's just not practical.

Sanborn/Coleman was bought out by MAT Solutions. A website I found lists Sanborn/Coleman compressors and parts but it does not show your model number. It does say, however, to email them with your model number and they will be able to find your parts for you. I have included the link for you here: http://www.mastertoolrepair.com/colemansanborn-portable-parts-freedirect-drive-electric-c-271_35_172_178.html

SOURCE: what type of oil should i use on my sanborn

You can use any 20 or 30 weight non-detergent motor oil in your compressor.

If you can remove the back cover of the motor, you should be able to see the capacitor. Do not touch any terminals, even with the power off, the capacitor holds voltage. You would have to locate it to replace it anyway. I had a bad capacitor on a pump last week and found one on the internet for $7 plus shipping. It is only a start capacitor, once the motor starts, the switch changes and runs on different windings.

Let me know if you need any additional information.

Don,
Do you have the model number of that motor. Don't do anything till you get the information because that would be a catastrophe if you get it wrong
