Well I do believe we fixed my air compressor and cured the temperamental rattle..
I ended up getting a set of short wrenches. I was able to work 11/16 around the compressor pully to turn the nut holding the compressor on. at times the wrench was at a 45 on the nut. Very awkward but manageable when climbing all over the motor. The wobble socket was never able to fit on the front two nuts.
After getting the compressor out and on a bench I was able to see inside the compressor and found no damage to the cylinder. The only thing that was found was an absence of an abundance of oil residue. With no belts attached and everything pulled away from the drive pully we decided to see if we could make the M35A2 produce oil. DO NOT DO THIS IN A CLOSED SPACE, NEAR ANTHING THAT CAN PRODUCE A SPARK OR FLAME, NEAR ANYTHING YOU CARE ABOUT, OR LIVING THINGS. My 70 y.o., disabled, father and my wife looked at the motor as I turned on the truck. For a while nothing happened. I jumped out of the truck and decided to take a look. As I leaned in to take a look under the hood, a 15' geyser of oil shot in to the air. With much screaming and laughter we were all able to get out of the way and I was able to reach the shut of for the motor.
I believe there was a clog in my oil supply to my air compressor. I was able to attach the belt and run the motor for a while with out producing the rattle. I ran out of time today to finish putting the truck back together. I will need more run time to see if it is fixed or if I need to find a check valve that has failed. The only casualty of today is the copper crush ring under the 1 & 1/4 nut on the top of the motor. That easier on the wallet than the price of a new compressor.
