Left bearing end that fits on sprocket shaft

[48Flatty]

Can the left bearing end (#24776-40) on the sprocket shaft be replaced without taking the motor apart? There is a crankcase bearing spring ring (# 24702-40) that I believe snaps inside of the left bearing bushing to hold the "bearing end " in place. I purchased a "Sprocket Shaft Seal Assembly" from Colony because oil is seeping into my primary drive along the sprocket shaft past the "bearing end" currently in place. The Colony kit comes with a new "spring ring" (or snap ring), but I am unsure of how to remove the existing installed snap ring to free the currently installed "left bearing end."
It appears that the "bearing end" in the motor is the same Colony type seal that I purchased. Has anyone had these seals fail? The motor only has about 1200 miles on it since complete build.

Its possible but very tedious to get the oil slinger out of the there. Depends upon how patient you are.

The oil seal assembly you are referring to is supposed to have an interference fit on its O.D.
I've seen "Rebuilt" engines that do not have a proper interference fit which is one reason for it leaking.

With this said, it would be very difficult, close to but not entirely impossible, to remove the oil seal without damaging the bore or shaft "If" it has a proper interference fit to begin with.

I hope this helps in your decision forward,
