Oil Bath on Shimano Nexus IGH

[@maciejfratczak4136]

may be a bit too much of grease. lubrication is done by an oil film and not the grease itself?

[@inforobertklein]

Ja serwisuję piastę inaczej. Pozbywam się starego smaru, potem robię kąpiel w oleju ATF, następnie nakładam trochę smaru EP-1 na łożyska i na wewnętrzną stronę obudowy piasty. W ujemnych temperaturach smar shimano nie sprawdza się dobrze, zmiana biegów działa wolniej. Do piast planetarnych najlepiej sprawdzają się smary EP, EPX w klasie NLGI 1 i 0. I service Piast differently. I get rid of the old grease, then I make a bath in ATF oil, then apply some EP-1 grease on the bearings and on the inside of the hub housing.At negative temperatures, the shimano lubricant does not work well, gear shifting works slower.EP, EPX lubricants in NLGI 1 and 0 class are best suited to planetary hubs.

I've dismantled, regreased the internals and then added oil (half a cup) by pouring in via the non drive side with the drive side installed to the hub. It's now noiser than before on freewheel but see how it works for now.

[@works4me]

Not sure I understand the half a cup of oil in the drive side. Did you mean you added and then drained it back out and reassembled?

[@JesusChrist-sx1lf]

1. Too much grease overall. 2. 4:38 You should use Shimano bearing grease for that not the internal hub grease but i suppose it still works.

[@samerm8657]

I respect your dedication to maintaining the gearhub, but isn't the frequency you clean and re-grease far too often? Not that it's bad, just that it may be time consuming on your part. Thanks for the video though.

[@works4me]

Yes it is Samer. I was really just trying to figure out if I had a problem and then I wanted to get good at re greasing the hub:-) Thanks for watching my channel.

How much difference did this make to the rolling resistance? I have an old bike with a Shimano Nexus 3 Speed. It shifts ok but if I have the bike up on a lift and give the back wheel a spin it barely makes one or two rotations.

[@works4me]

Sorry for the late response. It didn't make any difference that I could tell in rolling resistance.

[@jeffmurdock8321]

On the old Shimano 333 hubs, back in the 1980's we would just take off the bellcrank, pull out the shift rod, and just shoot some oil down the axle. It seemed to do the trick as I never saw one fail. Can you not just do the same thing to these new hubs as well?

[@works4me]

Hey Jeff, I don't actually know the answer to your question. Maybe someone watching the video could help on that one. Thanks for watching my channel.

[@jeffmurdock8321]

@@works4me Thanks for the reply. I know the old Sturmey Archer 3-speed AWs were oil operated and had an oil cap drilled into the hub housing. And I've seen old coaster brake hubs with those oilers as well. I'd bet oiling through the Nexus axle would do the job and extend your big overhauls to every few years.

[@ashfrost2050]

From my experience, using lots of grease like you have is the worst thing you can do to these hubs as it makes them noisey and clicky as it binds everything up. For me, I just use the shimano oil and bath it in a similar way to you (but i don't bother disassembling the drive side).

[@works4me]

Mine is very quiet with the grease. After cleaning the grease out and reoil bath no difference in loudness or smoothness.

[@davenportmb]

This is the way.

Shimano gear hub grease has different texture compared to regular bearing grease

[@quenar]

@@davenportmb :D

[@JesusChrist-sx1lf]

@@Your_username_ Yes, he is only using Shimano Internal hub grease in this video (white or black), not bearing grease for 4:38 which is a mistake.

[@jbrizz99]

I think you should try to to clean the grease out with a solvent, even dip the whole mechanism in it. The thick sticky grease might be why there is excessive friction inside the hub.

[@works4me]

I agree jbrizz99. I'm gonna do that here in about 1000 miles. Thanks for watching my channel and the comment.

[@jrshaul]

@@works4me any news?

[@works4me]

@@jrshaul Cleaning out the goopy stuff this time didn't make any difference as far as resistance or smoothness. It looked better but... wouldn't worry about it now.

[@jrshaul]

​@@works4me I'm running mine on 90W gear oil. Hasn't blown up yet, and that was a trash find. Any suggestions on drilling a hole? I'm filling it with a BBQ injector syringe and it takes ages.

[@funkefuchs955]

I am thinking of getting a bike with nexus 8 for commuting, do you think it is a good idea?

[@works4me]

Yes. This is a good choice as you have plenty of gears for most any situation. Pretty much no bike maintenance except chain cleaning and lubing🙂

[@rlchardpritchard7426]

I wander if you can help me with nexus 7 hub

[@works4me]

Hi Richard. What exactly is the problem with it? Do you get all 7 gears or just 3 or?

[@rlchardpritchard7426]

@@works4me I need to service it bearings are rough

[@works4me]

The bearings are the easiest thing to replace on these. It would be just finding the right ones online. Make sure you can identify the exact model of your nexus 7.
