‘99 Fatboy

This bike came to me in terrible condition, lots of stuff to figure out.
I have anrear axle spacer problem; The spacers that go between the bearing and the swing arm are 1 3/8” and 5/16”. It definitely needs longer spacers... I can’t get in there to measure, but it looks to be 1 1/4 - 1 1/2” too short overall.

These are aftermarket wheels, so I’m not sure if the wheel hub width is the same as stock.

I’m at a loss what and where to measure to get the right size spacers for each side.

I’m hoping someone can tell the stock spacer sizes left and right, that might get me pointed in the right direction.

 

Never mind, I’m a moron... I haven’t put the brake caliper bracket in place!

 

If it uses tapered bearings it should use original spacers, but being aftermarket, who knows....

Front and rear outer (bearing) spacers Part# 43654-86A that go thru the seal are .750" on both sides, front and rear, with the brake caliper mount being the only right outer spacer.

The left outer spacer Part# 41595-86 is basically 1.25" but you'll see them listed anywhere from 1.225 - 1.230

Front wheel
Left outer spacer Part# 43674-95 is 1.420"
Right outer spacer Part# 43657-89 is 1.00"

 

AFTER ALL THAT!!!! YOu owe me 2 cups of coffee and 3 brain cells.....

LOL, it's all good

 

ha ha, well the coffee I’ve got, but if you haven’t figured it out yet... I don’t have any brain cells to spare!
