You asked for a hub dynamo service, here it is!
Shimano DH-2N35 front hub, I show how to service drive and non-drive bearings in hubs with a Shimano dynamo.
By the way, I gain valuable experience myself and finally damage the body cap (which, fortunately, is my private).
How to do it, what to avoid and the most important ...
... will it work after the service ?!
About all this, in this material!
