This was really well explained. Best I have found on TH-cam or anywhere else. Thanks a lot. I have a R100S -77. Bought it with no maintenance history and now I will be able to check the rear wheel. I belive the front wheel bearings are assembled similar. Can the preload be checked the same way be pressing the center spacer? Regards from Norway.
The front wheel has a different set up without the large centre tube. Instead there is a large internal spacer with the smaller adjusting space held together by a plastic outer sleeve. This is preset at the factory and not requiring any changes when the bearings are renewed. If there were no issues with bearing failure before renewal, it will be fine with replacements bearings.
I’m not sure what you have there by way of a rubber ring. There are just rubber seals either side externally. On snowbums diagram #9 is the replacement steel shim. Which diagram?
Thanks for the reply. In your video at 2:29 when you put the inner ring on the axle what is the band on the outside on the centre of the inner ring. Is that the rubber ring which maybe acts as a spacer between the inner and outer metal sleeves. The shaft seal is #4 on my exploded diagram. #9 simply stated “ring”. The shim or wedding band is not labelled and on the exploded diagram sits between 9 and 6. Any thoughts?
Got it! On mine I think it was a metal band attached, I don’t recall it being a rubber ring. But part 9 goes on the outside of the inner spacer tube to hold it roughly in place, to make the wheel spindle easier to fit through.
Okay Nice thanks. From what I’ve learned I’m guessing your R100 is a pre 77 model. I’ve seen a few iterations of the central tube. Some of them have dual what I’ll call “inner tube positioning rings” . Anyway thanks again for posting the very concise vid. 😊
Thanks great vid, iam about to check the front wheel on my 73 R75/5 there seems to be about 5 mill play when i rock the wheel rim when i spin it everything seems ok
thanks so much for that, i watched a few vids and it was all about special pullers and fancy tools, nice to know its possible in the home workshop. one question, would overtightening /not torqued enough the wheel axel have any effect on the pre load?
Great vid, ive bought a R75/5 and its has so much movement bearing you can see the wheel hub move when you rock the wheel
Sounds like it’s bearing time! not difficult. And generally the boxers don’t need much doing in general.
Thank you very much for your work ! I’m inheriting a 74’ R90S that will need this.
🙏
You are a very lucky man!

Wow, thanks for the quick answer and Happy Christmas 🙂
The S version is possibly the nicest airhead for the road. Is yours the Brembo brake version?
A perfect explanation. Thank you 👍
Thanks for that effort.
On my 77 100/7 spoked a rubber ring came out of it. It’s #9 on the diagram. Do you know where that goes.

That sounds excessive! Must be toasted bearings or incorrectly rebuilt.
@@rustynuts82 thaats my thinking too

Not especially. It all pulls up against the spacers. Under tightening might well give a false reading.
great tutorial :D
