Alfine 8 13.000 km dissasembly, inspection and oil

UPDATE 2022 - 15.000km: Recently I have been able to make this hub occasionally skip in the first and second gear by standing on the pedals and pulling hard on my handlebars for maximum torque. While this is not a very common usage case, it does show the limit of what this hub can handle. Contrary to what seems likely, it's not the gears skipping. The limit is caused by three tiny pawls that are located on the centre axle. (13:00 minute mark) Depending on the selected gear, one pawl will extend and hook into a ring around it. This way the hub changes gears. It's this pawl design that has it's limits when torque becomes very high. The Alfine 8 speed is still excellent value for money, but I would not recommend to use this hub for climbing steep mountains or any other thing that forces maximum torque in gear 1 or 2. ---------------------------------------------------------------------------------------- I've been running my Alfine 8 speed (SG-S7001) on gearbox oil for the last 13.000km. It's been working great! In this video I show you how to disassemble the Alfine 8 speed yourself and how to add the oil. And 'for science' I open up the internal gear system to see if any parts or gears have worn out during those 13.000km. I also compare the internals to an as good as new Nexus 8 speed (which has the same gearing system) At the 10:50 minute mark I mention the internals are interchangeable. This means you can grab the Nexus 8 speed internals and put them into the Alfine 8 speed. I tried this and it works fine. Lastly, thoroughly clean the the gearing system with brake cleaner so there's no white grease left. You don't want oil and grease to mix together. If you use one of those extension straws it's easier to clean the inside. Don't forget to let all the brake cleaner evaporate before you put everything together again.
