Hmm, that is odd. Did you measure the diameter of the pin?Maybe, but I'm highly suspicious of that. Either way, that isn't the reason Denny gives for why a greasable shaft can't be rebuilt as a non-greasable. If I'm reading it correctly, they refer to an incompatible fitment issue where the "greasable" pin can't be assembled to a non-greasable centering yoke.
