Question and Answers

Q:

I have an air compressor, model 919-152811. I am Rebuilding the air pump. When I turn the fan, it rubs on the connecting rod.

A:

The model number you sent does not run in our system. Please verify the correct model from the tag on the compressor if you need more specific information.

If the motor shaft has gotten bent, the fan will rub on the connecting rod. If the connecting rod is bent it will cause it to rub.

If nothing is bent and you have incorrect spacers on the motor shaft, the fan will usually rub all the way around.

Go to www.searspartsdirect.com and enter the correct model of the compressor. You can see a parts diagram of the compressor with the location of the spacers for your model.

When a compressor continues to break rods, it is usually because the nut that holds the rod on is not torqued correctly.

I am sending you an image showing the correct torque specs for the compressors.

Q:

While using compressor heard a popping sound and the motor got loud - I shut off right away - had enough pressure bult up to do what I was doin at the time.

A:

Thank you for your question on the air compressor all of a sudden making a strange noise.

There are a number of air pipe connections and fitting you may want to check first. Also take a look at the check valve that goes into the air holding tank and the small pressure relief line that goes to the pressure switch.

It sounds like from your description that one or more reed valves have broken in the compressor head.

I would suggest removing the head on the compressor and examine the reed plate.

Please let me know what you find out.

Thank for the update on the air compressor. I am glad that you found the problem and I would suggest replacing all the fitting connections on the lines. They use the orange rubber rings to reduce vibration and breaking of the aluminum lines. Having a spare is always a good thing to have so you do not have to wait for a parts order. Sam A.
