Alternator Drive Dampers Tip

I'd like to submit a brief tip to add to Don Eilenberger's article on replacing the alternator drive dampers on a K-bike.

The hardest part in replacing the rubber alternator drive dampers is lining up the damper holder with the alternator drive vanes. It is impossible to see what you are doing as you try to mesh the two parts.

Two things can make things much easier.

Using a felt marker, mark the outside of the damper housing where the gaps in the goobers are located so you will know where the vanes will slide in. Using the rear wheel and fifth gear rotate the engine to place one of the drive vanes in the 12 o'clock position. Now you will know where the vanes are, even though you can't see them.

Rotate the damper housing to place one of the gaps at the 12 o'clock position, and then visually guide the alternator into place using the mark and your knowledge of where the vertical vane is located.

The silicone grease Don Eilenberger recommended will help hold the goobers in place during the operation.
