Question about Craftsman Air Tools & Compressors

Open Question

I have Sears Craftsman 5hp air compressor with 20 gallon tank. It runs fine for a while but eventually slows down to a stop and won't start again for quite some time. If I keep running it when it slows down it'll pop the breaker. The kid a Sears said that commonly it is the over heat sensor that thinks the motor is over heating but really isn't . What do you think? Thanks, Brian Lester

if shuts down at 20 psi regulator is set wrong
it runs but only builds 20 psi, compressor is probably worn out

1988 20 gallon 5hp sears air compressor leaking quite a bit of oil. Can it and is it worth repairing?


I would think that is is actually coming from the crankshaft seal and running down. Does it leak when you are not using it, or just when it is being used? If it leaks even when it is not being used then it could be the drain plug. If it only leaks when being used then I would look at the crankshaft seal. And yes it would be very feasable to repair it, because like all things they don't make them like they used to.

What type of oil to add


Mobile synthetic 10-30 , Craftsman compressor oil if K-mart or Sears are near by. You can also use a non-detergent 10 - 30 motor oil , I use Mobile or Craftsman in mine. I have three - one is a Campbell Hausfeld this oil is per their book - (minus the Craftsman)

How do i change my craftsman 919165200 air compressor from 120v to 240v?


Your Craftsman model 919.165200, 5hp, 20 gallon compressor was designed to run on 115~120v 15amp. I believe that it was made by Campbell Hausfeld and is of the oilless single cylinder type. If however your compressor is oil lubed and has a motor /drive belt configuration it may be able to convert if there is a spec plate on the motor with alternate wiring diagram. Many high-end compressors like Rol Air, Jenny, Dewalt, etc with motor/belt drive have a switch selectable voltage, however one must still change the power cord when using 220v. Good luck with your projects and post again if your have other question.

Craftsman compressor won't cycle off


Hi, First, I think the cutoff pressure is 135psi and there is an overpressure valve so let it run a little longer. I don't know exactly which model you have ( some of these were oil less) but if it is running longer than you remember, be sure to check the oil if necessary, make sure you are not using a long extension as this will cause the motor to slow down and definitely check to make sure the water is drained and the drain petcock is closed all the way. Also check it without an air hose attached. Good Luck!

Air compressor w/5hp motor


Assuming that the motor is factory matched to pump, it should be powerful enough to turn the pump. Most problems with motors are related to pressure switch and/or capacitor. The pressure switch could have burned contacts causing low amps to reach the motor. The capacitor should test at least 90% of rated value printed on capacitor. Some volt meters have capacitor check setting. Also this motor at 5 hp must draw lots of amps. The outlet should be rated at least 20 amps and plug the compressor directly into oulet without an extension cord. \
Secondary problem is the in-tank check valve. The check valve should hold in tank pressure without leaking back to the head of the pump. If check valve leaks, replace it with any brand of same thread size. enjoy

Coleman 5Hp Compresser


All electric compressors share a basic design with ac power pressure switch with unloader and checkvalve between the pump and the tank. When the pressure switch powers off, it unloads the compressor by releasing the air in the discharge hose. You will notice a small tire stem pin and a lever to engage it somewhere on the pressure switch. If the compressor stops before reaching set cutoff point, the air pressure remains in the discharge hose not allowing the motor to start, thus the hum you hear. Solution is to check for the proper function of pressure switch /unloader, tank check valve (if check valve leaks air back to compressor it will load motor causing hum) and extra measure check capacitor for at least 90% of rated valve. Finally, do not run this compressor with an extension cord, use more hose instead. enjoy
