Looking to swap the spoke rear wheel on my 07' wide glide for a solid wheel. Does anyone know if bearings are interchangable? Is the outer diameter of a 3/4" and a 1" bearing the same?

 

The OD is the same and so is the width. Going from earlier to 07, you will likely need to bore the hub for a larger inner spacer.

 

3/4 an 1" are the same...25 mm are thinner...so you're good

 

What is the 'solid' wheel you have in mind? I have a Duece in my Glide.

 

It was in fact a deuce.

 

The OD of all three bearings the MoCo has used in recent years, 3/4", 1" and 25mm, are all the same and interchangeable. I used 1" bearings for fitting my Deuce wheel in my Glide, the same size as I believe your Dyna uses and they will fit into the bearing pockets in your Deuce wheel. I bought a H-D bearing kit, which came with 1" bearings and the correct bearing spacer.

It is likely that you will have to bore through your Deuce wheel, to increase the diameter of the central hole, to take the larger OD bearing spacer. Install the bearings as per your own FSM and you should be fine. The stock Duece tyre is wider than on most previous Harley wheels up to that time, so take care with clearances.

WARNING! The Deuce wheel is essentially a special and has a trick hidden up its sleeve. While your pulley and brake rotor will both bolt right on, they will expose holes into the interior of the wheel casting. There is a disc of shim steel available as an H-D part, which I recommend you install behind both pulley and rotor. These will keep out rain water from filling your wheel!
