M923A2 Air Compressor Rebuild Parts

[NJDEUCE]

Can anyone point me to where I can purchase the parts to rebuild the air compressor on my M923A2? The compressor failed on me last Sunday, and I barely made it back home. I checked the whole truck for leaks, and did not find any. I recently rebuilt the air dryer, so that was not the problem either. I dove into the project of removing the air compressor today, so all I need is the parts to rebuild it. I should also mention that I disconnected the outlet hose from the compressor and was able to hold back the pressure with my hand. After I got the compressor out I pulled the four bolts off the top and the gasket was completely destroyed when I went to open it. I'm thinking that may be part of the issue. I would like to rebuild everything I can while I have it out of the truck. I need all the gaskets as well. If anyone has done this before and can help me out that would be awesome.

Part number on the compressor is Holset 3558006 SS296

I've tried searching for any parts I could find, but im hitting dead ends.

Thank you

A lot of guys here have just changed the gaskets and been good to go, I will look for the numbers....

Cummins dealer, gaskets 4920062 , 154018, you can give them the engine serial number and double check that these numbers are right.

Thanks for the numbers davo, unfortunately my cylinder head got cracked when I was taking it all apart...ugh. Does anyone have a source for M939a2 compressors? I can only find ones that are close to being right, but not exact, even with the part number.
