If they had to stop #7470 due to a overheated bearing, I wouldn't be surprised to learn it's the same main rod crank-pin bearing on the fireman's side that they have had trouble with for years. If I remember correctly, the crank-pin has a reverse taper " Outside diameter is larger than inside diameter next to where it is set into the driving wheel. At the time 20+ years ago when I was around I took several measurements with my machinist measuring tools and offered a solution, besides making new bearings & pumping automotive ball joint grease into the void. Really made it bad. I'm surprised nobody has been able to fix this yet.
My solution to this issue if it is still the same one as I believe it is will be available to Mr. Swirk.
