So I got some cast wheels and I'm trying to hunt down all the internals for it. It's an 84 xlx. I bought the bearings and seals from j&p bought having a tough time picking internal spacers.
For the rear Harley parts list 3 different spacers.
HD 43604-78 SLEEVE, BEARING SPACER - 4.420 (W/O FLANGE) (ORANGE)
HD 43605-78 SLEEVE, BEARING SPACER - 4.434 (W/O FLANGE) (YELLOW)
HD 43606-78 SLEEVE, BEARING SPACER - 4.448 (W/O FLANGE) (WHITE)

Then 3 for front
HD 43623-78 SPACER, BETWEEN BEARINGS - 2.564 (VIOLET)
HD 43624-78 SPACER, BETWEEN BEARINGS - 2.550 (PINK)
HD 43625-78 SPACER, BETWEEN BEARINGS - 2.536 (GOLD)

Any help would be appreciated

 

You have to set the bearing load and can only tell my trial and error. That is why there are so many spacers. You will never know till you check it which one to use. You can all so use the latter set up where you use a spacer then a special washer and shims. I have set up a many a wheel in 44 years of riding and working on them.
