Hi compressor drive motors tend to have sealed bearings wich cannot be regreased unless they have been removed but i would suggest that if you are going to remove the drive motor end covers that you remove the bearings for replacement as they are not as expensive as some people would have you believe
hope all goes well

Why is my compressor humming every three seconds or so?utive?


sounds like the motor is seized, disconnect power then open the rear cover and use a wrench to free the motor. If the motor spins freely you may have a faulty motor starting capacitor

Craftsman model #921166390 motor


The motor does not take oil on that unit. The compressor housing does though. If you cant get it to start after it ran dry, the cylinder is most likely seized to the piston.

We have a 2004 XAS 136 rotary screw compressor. The problem started suddenly. Engine starts and runs fine. On activating compressor, (blue button) there is a bit of exhaust smoke and engine seems overload....


First check oil level in both the engine AND the compressor if it has an oil sump.
It ounds like the piston rings or cylinders are scored causing the engine to have no power under load and to burn oil, and the compressor may also be seized.

if there is the correct amount of oil in the engine then consider an oil change and add some

to both engine oil and the compressor oil (providing it also uses ordinary engine oil too)

Air compressor will not start.


When you are texturing walls you need a texture machine, they work very differently from an air compressor. An air compressor, especially one as small as the Central Pneumatic 40400 cannot supply the constant flow of air required by texture guns. If your compressor was running long enough to get hot enough to smell it then stopped working some of the possibilities are:
- Popped a circuit breaker, either the house breaker for the outlet you were using or the breaker on the compressor motor. This usually occurs because the compressor is being run on a too small guage or too long extension cord or run constantly for an extended period.
- Motor got overheated and seized up or shorted out. This could be as simple as a bearing seizing or as bad as the coils in the arnature shorted out.
- Pump may have seized up. Even if the sight glass shows the crankcase is full, the condition of the oil and its ability to lubricate are greatly affected if it is overheated.

I started my air compressor for the first time without any oil. Now it makes a buzzing noise. Is there a "simple" solution other than replacing the motor?


Running compressor without out oil generally will damage rod and deposit metal on crank lobe. Metal can be removed using 400 grit sandpaper cut into one inch strips pulling back and fourth untill lobe is clean as new. You will only need to buy the rod(about $20) and one sheet paper. Remove pump/motor from frame, remove two bolts holding cylinder to body and airline and pull up on cylinder to expose piston/rod. Usually the rod will slightly coat the crank with metal and seize. Remove or work rod off lobe. Clean crank area and add fresh oil. Parts available at www.toolpartsdirect.com Good luck

Mine does not want to start. Uses up to much pwr and kicks off

I can think of many problems that could cause what you are experiencing.

Are your using a long, small gauge extension cord? Too long and too small of a cord will starve a motor of the power it needs to run properly.

Check the oil level. If the oil is too low the piston can seize to the cylinder. Too much oil can cause excessive pressure in the cylinder, stopping the motor.

There could be a bad bearing. A seized bearing can cause enough resistance to stop the motor.

There are a couple of capacitors on the motor. At least one of them will be used to help start the motor. A motor shop can test them to see if they are both working properly.

Those are the most likely causes. You will need to do some testing to figure out which is causing your problem.

I hope this helps with your repair!faeaa56.gif

A/c clutch seized


Sounds like you may have debris in your a/c system. From what you describe your going to need another compressor but before you hook the lines to it do a couple of things. Remove the reciever drier. remove the expansion valve. With the all the componants removed flush the lines and system. Flush kits are available at most parts stores. Install new expansion valve , new reciever drier, hook up new compressor. (make sure you add pag oil to the system, Check how much the system holds and add accordingly) Evacuate and recharge and you should be good!

I have a craftsman air compressor (small) with 2 wheels on end, my probelm is when i plug it up it buzzes only, will not start motor, what could be problem


unplug it and see if you can turn the motor pulley by hand, it should turn freely. If it does, check to see if the motor runs with the belt off. If the motor runs by itself then either the belt was too tight or the compressor is seized.
