Sears Craftsman Model 919.165612 will not build pressure.

Compressor will slowly build pressure to 60 psi and stop. It will continue to run , however it will not build anymore pressure. I suspect it is the check valve after reading the manual. I removed the check valve and the valve disc moves freely. I can't tell if it is worn. What is the best way to tell if the valve is bad?
Actually Pressley, I don't think it's the check valve at all. To test the check valve, blow into one side of it, and then the other. Air should only flow in one direction and not the other.
In your compressor, I suspect you've got a gasket leak or a valve issue, or both.
Both issues are covered on the pages linked from "Compressor Won't Build Pressure".
Need to replace the belt. unsure of the model number
70's air compressor bought at sears. no model numbers left on machine need a serpentine belt. 1/2 inch wide 6 rib 49 inches long
Take the old belt with you to an automotive type parts store or to a farm implement outlet. Both typically have a vast collection of belts and should be able to give you one that is a match to yours.
Typically the belt brand is immaterial as long as it fits the application.

Sears Craftsman Air Compressor .110- 220 conversion
Sears Craftsman Air Compressor . Model #919152920 4 hp ,110- 220 conversion. How do I convert my compressor from 110 volt to 220? This model is supposed to be convertible.
Joe, as long as the motor has the power to run the pump, the compressor doesn't care what the motor voltage is.
Assuming you have a 220 Volt power supply available, the motor will have to be wired for 220 (again assuming it can be) and you'll either need to wire it to a junction box, or add the appropriate plug on the motor supply line so it can plug into a 220 volt outlet.
As to re-wiring the motor, if the instructions are not on the schematic, you'll need a motor supply shop or electrician to do that for you.
919.152930 switch 220 to 110
(Tucson AZ USA)
I would to run a 919.152930 on 110 but it is currently wired for 220. can it be switched to 110 with no ill effects?
Kenn, it depends on the motor. If the motor is capable of being run on 110 versus 220, then the switch is easy.
I can't tell you if your motor is suitable.
You may have to purchase another motor, and, you need to make sure that the 110 volt motor can power the 220 pump.
If the current HP is a 3 HP or larger, you likely cannot get enough power on a 110 volt circuit to run a motor big enough.
