[Farmall] Super M Fan Belt

[RICHARD POPE]

Mike & Dean:

I got the old fan belt off this afternoon, but it wasn't a quick job.  The threads on that fan pulley sheave were so clogged with almost 60 years of grease and rust that the thing wouldn't turn.  Used lots of penetrating oil and then chased the treads with a small screwdriver.  Got the belt off and left some of my DNA on the fan blades, but that's normal.
Many thanks for your help!
