The harder you pedal during shifting or right after, Berkin sg ch05 louder the noise. The Rollerbrake and coaster brake are weatherproof, but drag slightly when not engaged, so if efficiency is a concern, avoid them.
For example commonly a ball or balls can come adrift from the ring bearing, either during assembly, or even in service if the bearing adjustment slackens. The old one would have to be extracted from the shell and a new one pressed in.
Basic models have a ratchet and pawls at the left side of the internal mechanism, and a roller clutch in the middle. There are several different left-bearing-cone part numbers.
Full cleaning and lubing usually restores like-new function but is expected that there will be slight differences in the noise over time. Care should be taken to release force on the pedals when shifting.
Aaron has photos of axles showing typical failures. Mix and match at your own risk. There is considerable compatibility between shells and internals provided the number of roller clutches is the same. Shock loads have also broken other parts of the axle assembly.
Shimano has information on most but not all 8-speed models. Instead, there are protrusions on the carrier unit. The internal mechanism of these hubs is complicated, and the usual repair is to replace the mechanism in its entirety. This is not possible with the coaster-brake or disc-brake models.
Coaster-brake models have at most one roller clutch. Factory lubrication is inadequate, and better lubrication is advisable -- even with a new hub -- also, to make later cleaning and rebuilding easier.
Shimano sells the axle assembly only as a unit and does not provide rebuilding instructions for it -- but you might disassemble it either by mistake or to cannibalize parts.
The right-hand hub bearing cup is vulnerable to damage from water contamination. Reader Bruce Dance indicates: I have seen one hub in which a roller came adrift presumably during the factory assembly, since they cannot easily come out in service and this smashed the hub shell to pieces.
Sometimes the shift spring on the axle can get weak or the axle sleeve that lifts the pawls can get sticky as it wears.
The Alfine requires a wider overlocknut distance than the Nexus without Rollerbrake.Making America: A History of the United States, Brief Second Edition Carol Berkin, Christopher L.
