serial # letter (super C)

A Suffix Letter Code, as outlined below, is added to the Chassis Serial Number as a means of identifying tractors with special features, thus facilitating servicing. This code applies primarily to special features that replace standard ports or units used internally but may also be used to identify tractors equipped with one of two or more optional ports wherein identification of said optional parts is deemed necessary to proper servicing. Each suffix letter used is stamped in the blank space following the serial number on the Chassis Serial Number Plate.
Attachments that do not effect replacement of standard parts or units have not been coded.
(Example: 100001BEJ represents a tractor with a 8000-Ft. High-Altitude Kerosene Burning Engine and Roclcford Clutch./
