looks like it had a bit of castor added to it. See other thread about castor, Lacquer thinner will cut it right off and some 600 grit paper will polish it fine.

Is 600 grit what you guys use for polishing journals?

I sometimes start with 320, then 600 and also finish with 1200. but i will say, if you look close at factory stuff new, 320 duplicates it. I personally like the 1200 finish, looks like a mirror.

I think factory left them slightly "cross hatched" not sure what to call it.  and not perfectly smooth so the roller needles didn't slide.

Interesting the crank has #40 scribed and  MF  6-1-73  and  MF 9-20-73 on it.

Someone suggested it may have been magna fluxed at some point and that was the date it was done?   Not sure what #40 was.

This motor has lots of interesting marks and things.

that was my first thought too yesterday when I saw the photos and it was before I saw the castor oil thread, so I wasnt influenced by that thread, this does look like many RC motors I have seen

Slick.  Looks like the rig I use for driveshaft seal area.  

How did you adapt a 1/2 inch drill chuck to a 3/4 inch driveshaft (or whatever) to turn it?

PS: Another nice video presentation, by the way. Did I mention where I got the idea for videoing my dink boat runbys?  From your old Dock Wrecker video.

I had a 5 inch driveshaft stub I use in the vise when working on crankshafts.   I drilled an undersized hole in the center of the driveshafts stub then drove a 3/8ths bolt in it.  SO both a 3/8 and 1/2 drill will work to spin a crank if needed.

I was hoping to have a lathe by now and all this would be much easier.  But the drill and wooden steady rest work fine.  The con rod journals I still had to without rotation,  but they were almost fine.
