Yes, you got it:) Wide gauge-special parts......most likely the special parts are a gearing option.

Paul - The last post in this thread will assist with understanding the S/N suffixes ..

Caterpillar have this to say about the "SP" suffix ..

“SP” stamped at the end of the Serial Number indicates special parts were substituted for standard parts on the machine. Examples include special transmission gears, oversized idlers in place of standard idlers, and other items that required special attention on the assembly line, usually “deep” in the machine. “SP” was not used for add-on accessories such as lights, cab, PTOs, crankcase guards, and mufflers."
