When replacing the rear tire, getting the wheel assembly to line up with both swing arms, the brake caliper bracket is a bit of a chore, especially if only 1 person is doing it.
As you know, the sprocket and wheel both have bearings/seals that must not be damaged while getting the axle bolt through to the other side.
So yesterday I fabricated a simple & cheap alignment tool that is tapered on the front end (to allow it to self-align all the holes as it goes thru). On the other end, the dowel is reduced in diameter in order to fit inside the axle bolt (which is hollow).
Working from the sprocket side, insert the larger tapered end of the alignment tool until it comes out the other side.
Place open end of axle bolt onto the small end of the tool and (while holding light pressure on the other side of the tool) gently push the axle bolt thru until the bolt head seats against the left side swing arm.
Dimensions are on the photo below.
