Early Harley Davidsons did it by making the crank pin a seperate part
from the two counter weights which went on either end of it. Held
together with *BIG* nuts on each end of the crank pin.

Brian Whatcott Altus OK


How do you install Roller Bearings on connecting rods? All the
Roller Bearings used in engines I have ever seen, were on
single cyl engine cranks that could be pressed on from each end.
I would think that any split shell Roller Bearing, would be less
robust than a regular shell bearing in the same application.

Me just wondering........
