Not my bike but I was involved in fitting a belt drive conversion to a mates Speedmaster on Sunday.
You really do have to strip the back end down to do the job. For most part time spanner men the swing arm removal is probably the biggest thing.

The pulley F & R are easy bolt on units.


Almost back together.
The hardest part was working out how to get the left side swing arm spacer bush back into place. We don't read instructions but figured out that by removing both spacers (the one clamped into the frame also) we could get the shaft and S/Arm back in, then slide the bushes into place before clamping the frame down onto the outer bush.

Finished job.
The rear wheel, rear caliper carrier and spacers are a bit fiddly to align.
You'll require a belt tension testing tool to finish the job properly if you haven't worked on lots of belt drive bikes.
