Here is some pics explaining the original intent and setup of the R 
series parts system.  This information comes from and IH publication 
called "What is a Parts Number?"  (IH Publication number A-90-II).   I 
had started an article regarding this a few years ago for RPMAG, but 
kids, Work, etc have gotten in the way.

Hope this helps.   Time for me to go to bed.
