Q:

Air Compressor 919153331 Stalls out 919153331 Craftsman Air compressor

A:

Thanks for the inquiry and for being a valued member.

I am sorry to hear of the issue you're having with compressor tripping the breaker on the refill. I know how frustrating that is to have happen.

The check valve on the tank holds the pressure in the tank when the motor shuts off. It also bleeds the pressure out of the discharge tube from the compressor. This allows the motor to start back with no back pressure to overcome.

If the check valve doesn't close well, it allows the tank pressure to fill the discharge tube. The motor can't start against the back pressure and will trip the breaker.

You will more than likely need to replace the check valve on the compressor. I have linked it below for convenience.

I hope this helps and thanks for using SearsPartsDirect.com. We appreciate your business.

Q:

Why did the squirrel cage fan on my Craftsman air compressor model 919.153331 break?

A:

I wonder, that upon the units starting, if the frame is torqued, causing the cage to suddenly twist and fail..... And if that's the case, I wonder if there is an underlying problem being masked by the cage breaking.... I will forward your question to an expert who will investigate the matter further and get back to you within two business days. Have a pleasant morning.

Thank you for your question as to why the replacement fan broke upon compressor start up.

I am not sure why it broke on start up.

Looking at the fan kit, if I remember correctly there is a locating hole or pin and then you use one of the two screws included in the kit to fasten it to the eccentric.

It seems like you were very careful in installing the fan so I am not sure what happen.

If you received instructions with the fan could you please send a copy to me?

Thank you.

A:

That is correct. I lined up the hole in the fan with the matching piece on the eccentric and used the smaller of the two screws that came with the kit (the only screw that fit & matched the one already in the machine). The only thing I didn't do was torque the screw to the recommended 75-90 in.lbs. because I don't have torque wrench that will handle that small of a screw. I did have the screw as tight as I could get it. I was hoping somebody may have experienced this problem in the past and maybe could tell me what is wrong. I don't want to order another fan and have it break also. They aren't cheap. I guess I'll have to take it to a Sears repair site, but that is also expensive. But at least they can't charge me for every fan they break until they figure out what is the underlying problem.

Thank you for the update on the fan for the air compressor. It sounds like that you have installed the fan correctly. If you turn the air compressor motor by hand to see if the fan is running smooth and not eccentric then you have done it correctly. I think you may have had a cracked fan blade. If you tightened it by hand you may have over tightened it rather that under torque the screw. I have installed a number of these over the years and it is possible to put it on wrong. That is why I suggested turning it over by hand before installing the shroud to make sure it is running true and not eccentric. Please let me know what you decided to do. Sam A.

A:

That bearing is the replacement bearing for this model. The flywheel part is no longer in production (and unavailable) but if it's in good shape, you can just replace the bearing. There is a set screw on the bottom of the flywheel that will have to be removed to take the flywheel off of the motor. The flywheel may be stuck onto the shaft (not uncommon). You can spray penetrating oil on the shaft and flywheel and allow it to sit for a while to help it to loosen up. You may need to use a small pulley or even a pry bar behind the flywheel to get some pressure on it while you tap on the flywheel with a hammer to break it free.

Thank you for using Manage My Life!
