106.153784 Craftsman Sears twin cylinder squeaks then shuts off?

106.153784 Craftsman Sears twin cylinder compressor
Model # 106.153784 sears compressor oil driven will power on for about a minute pressure only reaches 30psi compressor rated at 150psi.
After a minute I hear a loud squeaking sound coming from the flywheel/pump area then it just stops while squeaking.
Daniel... check the belt tension and alignment first please. That may not be the problem, but lets eliminate that as the source.
What I surmise from your post is that as the pressure in the tank builds, the pump has to work harder to get air into the tank. As a result, the motor has to work harder too.
If the pump bogs down to the point where the motor cannot cycle it, the motor will overheat and go off on safety.
With the tank empty, remove, inspect / clean the tank check valve. Again, this may not be the cause of the issue, but lets get it out of the way.
Assuming that it is not the motor that is squeaking, that suggesting that the motor itself is the problem, I am guessing that you may have a valve problem in the pump, that's backloading the pump and overloading the motor.
If you run the compressor with the line from the pump head off, I suspect it will run with no issues, right?
After you put the line back on, pull the pump intake filter and feel if air is being pulled in strongly as the compressor runs.
If so, that would suggest that the issue is the high pressure valve, and that means a pump teardown and valve replacement.
bleeder valve air compressor 921.16472 not working
(Mcpherson KS USA)
have replaced bleeder valve, and the little pin on the bleeder valve stays open(condensed) not allowing the tank to fill. Air still leaks. Is there an adjustment that needs to be adjusted? Notice that there is 2 screws in the general area.
Josh, if by the bleeder valve you are referring to what I would call the unloader valve, it is supposed to open when the compressor has reached cut out, to allow air over the piston to bleed off.
Then, when your air compressor starts, a pin on the side of the pressure switch trips, allowing the unloader valve to close.
If air continues to bleed out the unloader valve while the compressor is running, you are correct, it has a problem.
Also, if air continually blows out the unloader valve while the compressor is stopped, that typically is not an unloader valve problem, but a symptom of a leaking check valve.
Could you add a comment here with more information, please.
919.165140 compressor making a bad sound ?
#919165140 Craftsman Air compressor parts diagram (Photo: www.searspartsdirect.com)
I have a craftsman air compressor model numbe 919-165140.
recently it started making a bad sound so I shut it off and took it apart.
I found out that the cylinder was damaged and the cylinder wall was scratched. I ordered new part and replaced it.
After putting it back together I plugged it in and turned it on and now it runs for about a minute and shuts off.
If I unplug it after about a minute I here a clicking sound and I can turn it back on but it repeats the process. Any ideas?
A couple of quick checks, Todd.
The first is to pull the switch cover, empty the tank, and start the compressor. Assuming that it does not run up to cut out pressure and stop normally, watch the switch internals (live power warning - be careful) and see if it is the switch that trips off when the motor stops before it is supposed to. If so, then I suspect the pressure switch may be the problem.
If the pressure switch stays on, power is flowing to the motor but the switch does not trip off, then my next thought would be to check the capacitors.
Why not look at these two first, then comment here with results, if any?

Craftsman model type (photos) and how to check oil level
I recently purchased a Craftsman 5hp 30 gal compressor. The identity plate has been painted over and I do not have a manual. Can you identify this compressor for me and tell me how to go about checking the oil level?
Richard, in the second photo you can see the base of the pump. There is, what appears to be, a sight glass. Below the sight glass is the oil sump drain port.
Typically the oil level in a compressor with a sight glass is to the middle of the glass.
What I am not seeing is the oil fill port. I suppose it is on the other side of the pump, behind the plastic shroud.
Sears has a pretty good parts department and can often supply manuals. Without a model number though, it will be hard to find.
Your request is posted in the hope someone can identify the model and help you with a manual.
