Is this done if the front play exceeds the amount that can be taken up by
the maximum thickness e-shaft spacer?

As I recall Lynn mentioned chamfering the bearings to be certain
the engine rotated freely.

Lynn, I need some help here.

Lynn is a racer that overhauls engines over and over again. 

I would think the spacer should be used to center the e-shaft and then
if the end housing main bearings rub on the e-shaft fillets they would need
to be chamfered.
