Easy assembly
Installing the bushing is fairly easy, provided you've thoroughly cleaned the shaft seat bore.
However, it's necessary to present it 'dry' to mark the two holes that will receive the axial set screws.
After drilling the two holes for the two set screws, you'll need to replace the bushing so that it aligns with the threaded holes in the shaft seat. Marking the generator line passing through its two holes on the bushing can help with this process.
The bushing I had to remove before installing the new one had been glued with epoxy glue!! A very bad idea, spending three hours cutting it and pushing it in while hammering it along the axis, risking damaging the seat's laminate!!
