Crash:
Two possibilities. If you have the later 40 engine with the prop drive mounted on a centering cone the front bearing is an R6. if instead you have the earlier version with the pro0p rive pressed on the 1/4" nose of the crank shaft the front bearing is an R4. In either case therear bearing is an R8.
Hope this helps.
And sorry it took so long for a reply, I just joined this forum.
