Question and Answers

Q:

oil in air tank 919176450 Craftsman Air compressor

A:

 

Thank you for choosing SearsPartsDirect.com. I will be more than happy to assist you. I can understand any frustration you may have experienced with regards to your unit. Let’s see what we can do for you.

With this issue it does sound like the rings around the piston would need to be replaced. I am showing that the parts for that repair are discontinued, and I’m not showing any kind of kit for its replacement. The only thing that could be done here would be to try and find a similar model with the same parts that are still available.
 

Hope this information has helped you.  Again, thank you for choosing SearsPartsDirect.com.

Q:

stops after pumps 20 or so lb. in it no more airwon twont go it slows thje pump while till the moter shouts down 919176450 Craftsman Air compressor

A:

Thanks for the inquiry and for using SearsPartsDirect.com.
Sorry to hear of the issue you're having with the compressor not building pressure past 20 lbs. I know how frustrating that is to have occur.

If the unit is not building pressure like it should, the air compressor probably has something broken inside the cylinder. 
Before you take the compressor apart, listen and feel for air leaks. Check to see if air is coming back out of the intake filter. If air is coming back out of the intake filter, the tank check valve is the problem. If you feel air coming out of the intake when it is running I suspect the valve plate is broken. 
Also check the tubing connections to the pump. If the connections are fine, you have to remove the head. The head is secured with four bolts. 
Directly under the head is the pressure plate. The pressure plate has reeds on it that direct the air into the discharge line and keep the air from going back into the cylinder of the compressor. Check the reeds for warping or breaking. If the reeds are damaged, you must replace the pressure plate. Make note of how the pressure and seal sit on top of the cylinder. 
If the pressure plate looks fine, I recommend setting it aside and inspect the piston and the cylinder. What usually happens is the piston ring wears and allows air to blow past the piston. When this happen the compressor will run longer and may never come up to full pressure. To repair this problem I recommend replacing the piston ring and the cylinder. Most compressors have a kit available that contains the piston, ring, cylinder, and the seals. Any time you take the pump apart, the gaskets should be replaced. 
Hope this helps and thanks for using SearsPartsDirect.com. We appreciate your business.
