Hi Denis
When you do swap them over make sure the gears have a small amount of backlash (4 thou is ideal). Too little backlash can not only ruin the dynamo drive gear but also the cam gear and crank pinion. Don’t ask me how I know this
.
If you do have too little backlash you can add a thicker gasket to the dynamo mounting tower. Too much backlash and you may need to linish the base of the tower.
Cheers
