Sprockets Drive sprocket spacer

[GW's Motorized]

I had an Idea of spacing out my drive sprocket a bit to help with chain alignment. I have very little room to adjust for chain alignment, and I don't really feel like offsetting the engine. The alignment is only off a few mm, but since these hibs are so wide I can't really move the hub or my pedal chain will have issues. Would this be a good option for helping chain alignment?

I found a pre-made one, but I would probably make my own from a chunk of aluminum.

You also have to be careful the nut goes all the way on, or else it will rub on the inside of the cover.

Otherwise some loctite and a good snug and it should be good?

Just so I don't mess anything up, is that nut reverse threaded?

You can make one of these. Find a washer with the correct I.D. and file a slot in it for the key. You can grind down the O.D. if it's too large. You've built harder things than this. LOL

I dont see how a spacer will work, that's a tapered shaft. Where is the shoulder that the washer will press against. My just my thoughts.

Ain't even a crank seal in that engine either.

Having never seen one, from the picture it looks like the bearing seal doubles as a crank seal and the spacer contacts the inner race.

That part doesn't go into the crank case. It goes into the area separate for the clutch.

I measured it with my caliper, there is a .3mm difference between the end of the shaft and where it is at the bearing.
