My alfine 8 wheel has developed an issue and i need advice 😥
Its only 2 years old and done around 1000 mile on the mtb i use as my offroad/shitty weather commuter. The hub was not in use most of 2015 as it had been snapping a lot of spokes. When i started using it again it sounded a bit rough so made a mental note to service it at some point, it also started throwing chains which i put down to a worn chain and poor tensioning, but a new chain didnt seem to resolve it. Its been sitting out the last month as ive had the SS wheel fitted to the commuter with a ice-spike tyre.
When i grabbed it yesterday the sprocket/gear-mechanism was seized solid, had to use a chain whip to free it up. So decided to pull the mechanism out and check it over. All the gears and internals looked perfect with clean grease one, but a bit of rust on the large outer bearing. When i reassembled it was feeling rough and still had a little play despite the cones being tight. A 20mile ride out and it was feeling very rough and now had noticable play in what looked like between the sprocket and the hub carrier (ie. they were moving separately). The chain also managed to throw itself despite being tight and the chainline good, which i put down to the movement of the sprocket carrier.
So is the internal mechanism/gear lump servicable, as i think its the inner bearing on the drive side thats goosed, but you cant seem to get to it? Everything on the net ive found is about taking it out as a lump and just dipping in oil. which im not sure will help me.
[note: the shifting has been perfect throughout if that matters]
