Putting speedy seal on sealing surface of crankshaft and got to wondering if anyone has tried to sleeve snout of crank where H.B. sits. Seems like H.B. should fit snug, being this is so important, but I've never seen one that does. If it was sleeved it would maybe center and balance better.
So if someone has done this, what sleeve should I order?
