Top Video thanks

Hi, thank you for a great video I'm wondering about the use of brake cleaner to remove the white grease as the 'Mannol' one I'm looking at buying online has a warning that it might damage some kinds of plastic... Any ideas?... Also wondering since you say that we don't want oil and grease mixing about the grease we need to put on the bearings to lubrication/prevention of water ingress and oil leakage - is it just the white grease that would be a problem? Thank you in advance.

Wat je ook doet, geen olie in Nexus 8 stoppen! De keringen zijn er niet op bedacht, waardoor er lekkage ontstaat. Gevolg is voortdurend olie op je schijfrem. Ik heb drie keer mijn remblokken vervangen. Toen was ik er klaar mee. Alle olie er weer uit en vet er weer in. Ervaring rijker.

Great video. To Those people with a CDX gates carbon drive. The sprocket needs a little help to come back on. There are three levers to lift the sprocket back upon the furthest ledge using a screwdriver before clamping back the springring. 👍

Can we use motorcycle engine oil?

Great video. I just needed it for maintenance. I aded fresh grease. Maybe some time i will try oil. Thanks

that video is awesome .....

BTW that C shaped "ring" you mentioned is called a C-clip.

what s the difference between SG-S7001-8 and SG-S7000-8 ?

Can you just use brake cleaner to clean the hub? Does it hurt the seals?

awesome video

what did you use to clean the gears? Regular breakcleaner?

In most other videos and instructions for this, I see people dip the unit into ATF, rather than inject it into the housing. Does anyone have any thoughts on which is better?

how does the oil not leak out? this thing is made for grease not oil

After watching this video, I did maintenance on my Alfine 8, with oil of course, and I will never get back to grease !!🙂

Why is the hub so filthy? I have bikes with more miles that look new...

Back in the 60’s my friend had an English 3-speed with a Sturmey Archer hub. I remember him having a little tube of sewing machine oil, and every so often he was suppose to put 2-3 drops of oil in the hub.

man chain drives are so labour intensive on Maintainence like i have to degrease and oil my chain every 15 days or the cycle performs like shit

please do not follow this guys example by NOT cleaning the wheel from months of grime. that bike is repulsive!

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.

Toi aussi tu vis avec ton vélo !?

The Shimano Nexus 7 and 8 and the Alfine 8 are not running on grease only. They also use oil. You can even buy special Shimano oil for it. But its insanely priced. 44€ for 1 liter!

I have got a gazelle C7 bloom bike from 2018. Its got a 7 speed shimano nexus 7 gear system. Its seems after looking some YT videos that a 3 speed or 8 speed have a better ratio in the gearbox. I have looked so far for parts to switch the system over to at least an 8 speed one.. Knowing i could find a shimano nexus 8 speed turn shifter (the original is a 7 speed nexus turn shifter) So i think that would be easy to swap if possible. Iam also think that a 11 speed gearhub wouldnt be possible on my bike. Iam really in a doubt to change out the 7 speed gearbox for a Nexus 8 speed or a alfine 8 speed gearhub. What is the benefit from a nexus 8 hub to a alpine 8 hub. It seems both are looking almost the same, and are also packed with grease to instead of oil. Can you give me you opinion what the best is to do? I really like to have a smoother paddeling action without to get tired to soon.

you can tell that it was lubed with oil based on the amount of oil built up on the outside of the hub lol edit: 1:37 there has definitely been some leaking. has it affected your rear brake?

Zojuist zelf uitgevoerd met behulp van deze video, bedankt!

thank u bro. 👍🏻👍🏻 saved my day 😂

there was a school outside Chicago for bike techs called Vance Bloom. I was the regional tech and presented the argument for oil then to the instructor. it is agreed grease is better for the occasional rider. as a commuter and tech...it's a simple task for someone set up for the work. the Nexus 7 was before this and terrific with oil also. like butter. butta.

my argument for oil began in Chicago. I left my commuter outside one night and had no forward in the morning. it freewheeled forward. froze the pawls closed. I use refrigerator oil since.

Very helpful! Am I the only one that suspects the domed nuts on either end are made of chocolate? I keep stripping the threads on these! BTW when new, they put a pitiful amount of grease in these. It's well worth servicing after a few months.

Great video quality. Also you might have saved my day - depending of wether I can put together the inner part that you left intact but I needed to disassamble due to rust ;-)

What did you use for the degreasing?

Van Gemert is een baas

On the original 3 speed gears you only has to add a few drops of oil now and then , thsts it , no strip down just ride . Why is it we always go backward, none of the new hubs have an oil cap ?

Thank you. Great video. Clear and good quality. Thank you.

Nexus and Alfine are mostly the same, except some minor differences in design of some internal parts?

Hi, I followed the instructions, but I made a mistake and greased the ball bearings with weldtite tf2. Should I clean it again a redo the process using ball bearing grease, or am I fine at it is now? Thanks!

Excellent, just what I needed! 👍

Hello, I was wondering if you can help with a problem. I have the nexus 8 hub which is making some unusual noises only when coasting or pedaling backwards, but no noise when actually pedaling foward, in that regards it runs quite nice. I've already checked the cable tension alignment which is fine, the dots match. Can you help identify the problem please or have any idea what to do. Thank you

Lavar essa nojeira toda com um querosone ou sabao antes é bom ne, adianta nd trocar o oleo e correr o risco de mais de 90% de chance de levar contaminantes pra dentro das engrenagens

Thank You! I will open my Alfine 8. It seem's to be very loud.

Can I say that this is one of the best tutorials I’ve watched in a while. Superbly filmed, you covered everyone question I would have had! I have the same hub so will be giving this process a follow. Thank-you

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.

Which Nexus 8 is that exactly? I am trying to fix my old bike for cheap and probably have to replace the internals of the hub. Would be interesting to know if I can also get an Nexus 8 instead of Alfine 8 since it increases the pool of used hubs on eBay.
