Dyna rear wheel install question
I did my first rear wheel drop on my '14 Low Rider and took it to an indy for a tire swap. It's a little more involved than on my Sporty. I loosened the belt tension adjusters evenly and put them back when done, but still did an alignment check to be sure. The ABS speed sensor was also fun putting back since I didn't notice exactly how it was situated when I pulled the axle.
Anyway, my question is about the spacer sleeve on the left (sprocket) side. It has a couple machined lines on one side of it. There's no mention of these in the FSM, and the blowup picture doesn't even show them. So as far as I could tell, there was no "right" way to install the spacer, meaning lines facing in towards the bearing, or out towards the fork.
I put it all back together and everything seems fine, but I haven't taken it out yet because it's raining. I did some Googling today, and found a variety of opinions about what the machined lines are for and how the collar should be oriented. The conclusion I came away with is no one really knows what the lines are for, and it doesn't matter how the spacer is oriented.
Can anyone shed light on this?

I went down the same rabbit hole when I took my rear wheel off to get a new tire as well. I'll try to find my notes and pictures a bit later today, but for now I can offer this tidbit. This is just my opinion but at the time I remember coming to the conclusion that the lines were possibly to help the assemblers at the factory tell them apart in their parts bins.

The "lines" are to be faced inward, toward the bearing. The rational for the lines is to reduce wear on the rubber seal lip that retains bearing grease. The reason that bushing has 3 grooves is that it is used on numerous bike models.

Doesn't make sense. The face of the bearing touches the face of the spacer. Nothing touches the outside barrel of the spacer, lines or not. I was watching a video by Ryan Urlacher and he says the lines must point away from the bearing, but he gives no explanation why. Mine happens to be facing inward.

The bushing fits numerous models. Some have the bushing partially insert into the hub. The factory installs the lines towards the hub. Not away from it. But, in the case of the FXDL's it makes no difference how the bushing go on. As long as it's there.

Ahh, ok. I did read some posts saying it varies depending on the bearing/hub design. Thanks!
