The main differences between the JD350B and JD350C are that the C went to a 3/164 CID engine from the 3/152 CID in the JD350B and that the JD350C changed from dry to wet steering clutches.

Sometime during 1985, the serial number scheme was changed and the new range started in the 700000 range. So, there are some 350C units showing serial numbers in the 700000 range prior to number 723603. However, we do not know the beginning serial number in this new range.

The source of the data is from a farm equipment quick reference guide that's intended to assist dealers in determining the year and current market value of trade-in equipment.
The guide as such only lists the beginning serial number for each year. I'm making the reasonable presumption that the last serial number for any given year is one less than the starting serial number for the successive year.
Thanks to Digitup for sharing the relevent pages from his guide with us so we can determine what year a given machine is.

Additionally, some model numbers contain an extra letter. At some point during the manufacturing of the 350B, they added a letter. Making the model one letter longer. Such as 350BE.
A - Diesel, Loader
B - Diesel, Loader
E - Diesel, Inside Dozer
G - Outside Dozer
J - Drawbar Crawler
W - Wide Track
The meaning of the letters csme from the JD350C manual section 1A3. There was no data on what the difference is between the A and B loaders.
