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.

@chrisbliss2034 3 года назад

Excellent tutorial, thank you. Sturmy archer, older cyclists will know, have been using oil in their hubs for well over 100 years . Their older models always had a little oil port located on the external hub shell to facilitate adding the oil. You can too----- an old woods valve can be converted into an oil port ; 5 mm metric thread on it plus corresponding hole and threading in your nexus/ alfine hub shell. However, it isn't necessary, you can just add the oil as per this tutorial, but it's much easier to have the oil port access. Choice of oil. Semi synthetic magnetic oil is v. good, and the 10w/ 40 lawn mower type rating is about right. The quantity is spot on ; even Rohloff say 12 mls. is enough to be adequate for their hubs . Too much is unnecessary and risks spillage. Also, be aware when you park your bike it's not angled too steeply as oil may leak then too. Oil in your hubs will make them last indefinitely and keep them and you happy! Ride on for thousands of miles...🚴🙏

@hokehinson5987 Год назад

Are you recommending 10W30 mower oil? Non- detergent? All we have here is 30 wt. Any multi wt oil is rated at the lowest number as the base oil. Therefore 10W30 would be 10 wt oil. Multi wt oils for automotive use have many additives a particular one is polymer. These polymer additives begin to thicken with heat to arrive at the highest rated number 10W to 30 wt. Have to ask the question if the hub generates oil temps high enough to make the molecular shift from 10 to 30 wt. If not then it remains 10 Wt oil. Also the detergent active is not a slick component it is's a chemical that keeps dirt and debris dispersed/ floating within solution so an oil filter can filter them out. Otherwise these contaminates would collect in the lowest area in the mechanism. Am thinking for a bike hub a detergent oil would be detrimental to bearing life. Hope this helps... excellent tutorial....

@jed954 2 года назад

Changed grease for gear-oil in two 7 speed hubs and my first impression is that the pedals keep in rest when the wheel is running. Our Dahon bicycle that is for months in the car had dried out grease so the pedals immediately were driven by the wheel. Thanks for this tutorial. ---A year later I discovered, that oil was leaking through de dust-rings behind the small sprocket and with some dirt it turned nog longer smoothly. After cleaning I replaced most of the oil by grease. To avoid problems with the dust-rings I cleaned them thoroughly and made the small one 0.5 mm flatter. In another bike everything is still OK, but I think it is no good to use lots of gearbox oil.

@XWA2203 Год назад

Thanks for the video! Great content! I just bought a bike with an Alfine 8 and it will be a great help for me. As per comment: I am actively putting old bikes back on the streets, those are usually equipped with old Sachs geared hubs (3, 5 and 7-speed) and the manuals always say the same you did here. Grease the planetary gears with oil (I use automotive engine or gearbox oil) and grease the bearings with machine bearing grease (I use some hi temperature resistant automotive one), the coaster brake should be greased with special grease which actually is a hi temperature resistant one :-). The only difference is that I am completely disassembling the Sachs hubs first and clean up every single part separately. Greetings from Berlin!

@trustthedogsheneverlies644 2 года назад

If you are worried about plastic and rubber parts perishing in the oil use "detergent free oil". This is what we use in old motorcycle gearboxes due to the fragile rubber seals. FYI Almost all lawnmower oil is detergent free.

@moto_rad Год назад

Thats not why bike oil is detergent free. The clutch is bathed in oil and detergents will make your clutch slip.

@hokehinson5987 Год назад

The detergent additives are not slick. These are chemicals that disperse contaminates in the oil keeping them in a floating state in solution so a filter can do its job effectively. Normally in non-detergent oil the debris precipitates out of solution collecting in the lowest area within the mechanism. Modern oils can contain an additive which affects the flexible seals found on rotating shafts. These additives bond to the seals. Renews them... to remain flexible and swell enough to do there job better after high mileage. These oils usually are denoted as high mileage oils. The old transmission tune up in a can popular many years ago was basically a solvent that swelled the seals so the clutch packs would not slip. After prolonged use the seals became to soft and would fail. Hope this helps..

Thank you for the high quality video. Concise instructions and incredible image quality. I bought a used bike with an IGH that was overtorqued, loosened the cone and it still didn't spin smoothly. I followed all the instructions, opened it up, cleaned it and gave it a good oil bath. The oil was practically shiny with all the metal shavings inside... I went from the wheel spinning 3 revolutions when spun at highest gear for 1 pedal rotation, to 10+ or uncountable. It doesn't spin as freely as a regular bike hub but a huge improvement though it does have clicking noises. I'm sure the bearings are shot but at least I salvaged whatever life is left in them... Very big thank you.

@multireel7590 Год назад

Yes, considering the price, which is about 7 times cheaper compared to a Rohloff 14 speed, it surely is. The Rohloff is still king when it comes to built quality, sturdiness and gear range though. I own one too since a year or so and the difference is very noticeable. Where the Alfine 8 speed has a bit of give when you stand on the pedals, the Rohloff is rock solid. Never managed to get the Rohloff to skip in extreme condictions which is something I can't say of the Alfine. But like you say, commuting isn't extreme and that's where the Alfine shines. Cheers!

@famkis8680 Год назад

When countering the bearing cone, note that this will reduce play since the cone will sit on the other flank of the axle thread afterwards. So you should adjust a little more play initially than intended, when tightening the cone.

@WarthogARJ 2 года назад

Great video, thanks! Really well made and very helpful. I have a Rohloff, bought 2nd hand, and I had to take it apart because the rim fell apart on me (2nd hand with the hub obviously), and part of it got wrapped around the hub/axle spacing and jammed the hub. Didn't work well after that, so I had a go at opening it up. Hmmmm.....TRICKY little bugger to put back together, but there are a couple of descriptions on the web, and I VERY carefully watched the Rohloff factory assembly videos as a help. So I managed. As far as advantages of oil vs grease, I think a big advantage is with oil you can replace the old oil regularily, including a "rinse", which will remove any wear particles. I've been looking at the lowest gearing you can put on the Alfine and Rohloff, more from curiousity, really. I cannot see any real reason why you can't go to lower gears than Shimabno recommends on the Alfine. Is obviously not an issue for you riding it in Netherlands...:-}, but for touring it's an issue. I don't think the issue is with actual overloading the internal hub gears, at least not from a short session of higher loads by exceeding their recommended gearing ratio. But rather over a longer period it tends to put more wear & tear on the gears, and you would tend to wear it out faster. So I think Shimano is really just trying to keep these hubs out of heavily loaded/long distance touring use by discouraging the more extreme gears. The reason would be that group is a very small fraction of their total intended market (commuters etc), and they don't want any failures talked up on the various forums etc by their use by tourers. Whereas Rohloff is more sturdily built, and can take a bit more punishment. Much more $$$ though.

@nickwf70 2 года назад

Yeah Shimano 8 speed hubs can take alot more torque then they recommend as they are very well maintained. Thousands of them on cargo bikes and electronic bikes. Mine was used with an electric bike pulling a trailer up to 100kg up 1/6 hills, still fine. I like to use a X2 front derailleur gives 16 gears. As standard 8 speed hub is geared too high for hills about 6mph and about 20mph downhill, that solves the problem. Rolhoff is too expensive, I don't want to park a rolhoff at the supermarket 😂.

@multireel7590 Год назад

I did look into the max torque thingy for the Alfine 8. Reason was I did manage to get the hub to skip on very high torque situations after around 15.000km . The cause? Is not the gears skipping. There are little pawls that extend from the centre axle to select the correct gear. These tiny pawls lock into a ribbed ring that surrounds them. During very high torque, these pawls can skip a bit inside that ring. Again, this only happens in really high torque situations and only in gear 1 or 2. I'ts pretty far from regular commuting use, yet it shows the limits of this hub. Meanwhile I also have a Rohloff and like you say: more sturdy and can take more punishment. Haven't been able to make it skip ever. I really did try. Pricey though :)

@famkis8680 Год назад

Awesome! I wouldn't have thought that the Alfine 8 is built to be oil-tight as the Alfine 11 is.

@borisstarosta7823 Год назад

Alfine 8 is not built to be "oil-tight" (see at 16 minutes in video). If you run oil in your Alfine 8, you'll be wise to keep the wheel "vertical" as much as possible. If you lay it down sideways, say in your car for transporting it, the oil will eventually flow out. When I upgraded my Bullitt cargo bike to a mid-drive motor, I made the move to running automatic transmission fluid in my Alfine 8 hub. Instead of adding 10ml of oil into the hub body, I simply dipped/submerged the entire planetary gear assembly into a bath of ATF. After an hour or so - to really let the oil soak into it - I took it out, let it drain for a few moments until the oil wasn’t “pouring” off of it, and then installed it in the hub body. It was a good decision to “convert” to trans. oil - shifting was improved, and it slipped/skipped out of gear less frequently. Now some five years after I made that change, I’ve taken the assembly out again for “maintenance” (really just curious - it’s been working fine). I observed zero wear and tear (though admittedly, I doubt I’ve put more than 3 or 4 thousand miles on it), and the oil that remained and dripped out looked basically still clean. I re-dipped/soaked the transmission assembly in new ATF, and re-installed it. I doubt that I’ll ever need to bother with it again.

I've ridden in hilly area's and the gearing was adequate and the hub worked fine. However, I do not recommend this hub for heaving mountain climbing or very steep hills. Not because of the gear range, but because of the internals reaching their torque limit in the lowest gears. I have been able to make the hub skip in one of the first gears by standing on the pedals and pulling my steering for maximum force. Although that's not a very common usage, it does show the limits of the hub design. I also got a Rohloff bike now and apart from the wider gear range, this thing is built like a tank. I really tried hard, but i have not been able to make it skip a single time the past 5.000 km.

10:41 Looking at the planetary gears, it seems like the Nexus hub has machined/steel planetary gears while the Alfine has sinter steel hardened steel planetary gears (you also mention the rounded edges on the alfine, that is also more common with sinter steel, since it is pressed into a mould). Purely based on judgement by eye, the typical golden color on the Alfine gears and the machine traces from the lathe on the ones in the Nexus hubs. The roller pins on the Alfine seem to be better quality steel as well. I would put my money on the Alfine in terms of durability for sure.

Did you mean to write Nexus in your last sentence (instead of Alfine)? I don't get it, which hub do you think is better?

@berendlucasvanderweide Год назад

@@kosztaz87 yes, correct. Thanks for your keen eye. I'll edit it

Excellent video! I have 2 bikes with Nexus 8 (c6000 & c6001) hubs and one with a Nexus 4 Coaster. Are the seals on these hubs sufficient to go "oily only". Thanks again for your clear instructions.

Did not know, Taiwan‘s Giant is going to assemble Alfine to their bikes. 🎉 Alfine 11 is with oil bath.

@multireel7590 Год назад

They don't, I put the Alfine there myself. This bike comes standard with the Nexus 8 speed.

@MrJob91 2 года назад

The biggest issue with these hubs is how the drive side bearings are difficult to service. Replacing the bearings will often result in a lengthy rebuild.

@aarioshahbany8440 Год назад

So I just finished fixing my gearbox following the video. The tool to loosen the break disk for me was: TL-LR11 That was it! It has 10 teeth. For different number of teeth a different number would be needed. For example TL-LR8 is for break disk lockring with 8 teeth.

@derekthompson2279 Год назад

Great video good explanation so you recommend the Alfine 8? Its reliable and does not slip unlike the Nuvinci?

@multireel7590 Год назад

The tiny gear selector pawls on the axle as shown at the 13:00 minute mark have to withstand high torque. They can go a long way, but the design wasn't meant to withstand extreme situations. I've had the Alfine 8 incidentally skipping in first/second/third gear when standing on the pedals and pulling my steering for maximum power when the green light hits. This happened at around 15.000km. Regular use was fine though and I could stand on the pedals in the other gears without a problem. I've opened the Alfine hub again since that skipping happened and switched some of the tiny pawls around with the ones from the Nexus. Not that I could see anything wrong with them, but after that there was no more skipping. Not sure how long this fix will hold. My takeaway is that for regular use, the Alfine 8 is still great value for money and works fine. However it's designed to be just enough and it's possible to exceed its limits if you're going for maximum torque in the first few gears. Since this video I also own a Rohloff bike and that hub is clearly a step up from the Alfine and hasn't skipped or slipped at all no matter what I do with it. It's 8 times more expensive though.

@Paul58069 Год назад

I'm sure these hubs will run great on oil versus grease. Grease adds more friction. But I could't help noticing the extreme amount of dirt on the outside of the hub. I'm guessing this is the drawback of running them oiled.

@multireel7590 Год назад

Good eye, yes it's dirty. Doesn't have anything to do with the oil inside the hub though. It's the chain lube spray I used a bit to generously.

@mennopieters3512 3 года назад

But the gaskets at the ends are grease proof but not oil proof of wil leak out thanks to the centrifugal forces sling it onto your rear disc brakes which makes them ineffective

@multireel7590 3 года назад

No, that doesn't happen. There has been no oil leaking the past 13.000km.

@robertktw Год назад

how often does complete disassembly needs to be done? is changing oil at regular intervals enough?

@jcvjcvjcvjcv Год назад

What do you see as "complete" disassembly? For the oil maintenance; mManual says; first time after 1000 km, then yearly or every 2000 km (whichever comes first), more under harsh conditions. Which is a pipe dream, mine is over 20.000 km and I only did it once. I ride every day regardless of weather.

@robertktw Год назад

@@jcvjcvjcvjcv no doubt, taking the internal hub apart is the best; I'll be happy with drains & refills ^^

@multireel7590 Год назад

Unless you think maybe water has entered the hub or the oil has leaked out for some reason, a complete disassembly isn't needed for a very long time. I would happily drive it for years to come.

@orangejerkorange4815 2 года назад

You can add an oil draining tap. So you can easily change oil and wash it. Shimano isnt even using full synthetic oil in their alfine 11

@multireel7590 2 года назад

Maybe I will!

@orangejerkorange4815 2 года назад

@@multireel7590 you have to drill the hole in the right place though and be careful about the length of the oil plug. Automotive gear oil has pressure additives that are unnecessary, toxic. Its probably best practice to use a thin fully synthetic oil. You'll probably end up with better frictiononal performance. More environmentally friendly too. You can use rohloff oil. It's fully synthetic and bio degradable.

@chadkline4268 Год назад

How does the gear range compare to the AdventX? They use different specs. Alfine 8 says 300%. AdventX says equally spaced, 11-48t. Does that mean Alfine 8 is like 11-33t? I guess? 😊 And Alfine 11 is like 11-44t? Does Alfine 11 still have problems? Could you have put more miles on your Alfine 8? You didn't say.
