M939A1/M923A1 NHC250 Cummins Air Compressor Replacement

Replacing the air compressor on the NHC250 small cam 855 cubic inch engine. Replacement Compressor is #3018543X. Replaced the coolant hoses as well. Along with the air charging line.

TM is 9-2320-272-24-2 Starts on page 898 (4-31). Compressor replacement number is a 3018543X. Can be found on ebay as well. Truckpro had mine. Always replace the plastic spider gear on the injection pump side Cummins # 3046200. I do a lot more crap than I probably need to.

There is NO timing on the compressor or injection pump. The military TM calls for timing but as long as the accessory drive gear did not get removed then everything else is fine.
