My rack setting charts (the bible) does not show a 49A engine in anything up to 1966.
Are you sure the 4 is not a 5 making it a 59Axxxx model which would be the D320. They are not that common an engine and were only used in the 933G model loader and the 922. Plenty of industrial engines, marine and gen set applications though.
a 59A4650 would be a 1965 model near end of production at 5147.
We own a 59A 922b that the previous owner had attempted to install a Perkins in. It was not a success. It involved machining the flywheel to fit the Perkins as well as doing away with the transmission oil cooler, fabricating mounts etc.
When they gave up on it, we bought all the CAT part of it and found another D320 to put in it. Had to replace the modified flywheel and overhaul the D320 which had been apparently been submerged in flood water at some point. I was lucky to find the D320 in the first place. I thought I needed a D330, and the guy we got the "new" engine from, thought he had a D330, but we were both wrong! Then Hector had all the parts I needed to finish the project. Thanks again Hector!
Pretty typical "machine out of the weeds" story!
No need for further investigation , the engine number IS 59A4650, i got the wrong number from my buddy!
