Title: Rear wheel bearing removal
Post by: jon stead on April 08, 2018, 10:10:59 AM
Hi, I’m busy renewing the rear drive rubbers and thought change the bearings whilst I’m in there. 

Looking at the bearing dimensions. The rh one is 52mm od and the lh side is 62mm. The left hand side has the bearing retainer, so I guess everything, including spacer, will just push out, right to left? By push I mean drive.

Any tips gratefully received.

I may be wrong, often am, but I think the best way is to move the spacer out of line enough to get a drift on the inside of one bearing and knock it out. Then you can knock the other one out from the other side. I've not heard of anyone knocking them both out together. HTH.

Hi, yes that does help. I’ve looked at the set up again, and I don’t think the right hand one will push through, it has to be sitting on a machined shoulder.

I will do as you suggest. Thanks for your assistance.

And they’re out! No heat needed, or PB blaster, whatever that is? Left hand bearing rough as a badgers so well worth doing.

Another question; when reassembling with new rubbers in the Cush drive, do you use any lubricant on the rubbers? If so what?

Talcum powder,as  any oils or grease will shorten the life as they attack the rubber

Would red rubber grease have that effect as well Hairy?

Not 100% sure on that one nursey, but always best to err on the side of caution with rubber parts. What does Trig use on his rubber clothes and toys? Tyre soap would probably be okay for cush drive rubbers as it's rubber safe, but I've never seen it in less than 5 gallon containers which is why I didn't suggest it.

He uses Fuchs Renolit Red Rubber Grease for everything rubber on bikes Hairy and the same for his clothes and toys . It's a bit if a pain actually as it's not water soluble, so it plays havoc with the washing machine !!! Yes, we also have a 5L tub of Tyre Soap and what he uses that for I shudder to think 🤣🤣🤣

Thanks Hairygit and Nurse Julie for your replies. I’ll get some red rubber grease although I’m sure talcolm powder would have been ok as well. I guess French Chalk would of been ok also?
Thanks again

Most homes have talcum powder, that's why I suggested it, but yes, French chalk would be fine as well.

Johnson & Johnson Talcum Powder is now listed as a Carcinogenic would you believe it. Makes me wonder how so many of us have got to the age we have !!!!

That’s it all boxed up now.

New bearings and oil seal, new Cush drive rubbers with red rubber grease. Only mistake I made was the bushing that the oil seal runs on. I thought it slid in once the sprocket and cover were fitted but found this to be wrong when I tried to remount the wheel on the bike. Had to remove the bearing retainer and fit the bush from the inside. All good now.

Thanks for help along the way.

Did you remember to grease the metal sleeving where the sprocket carrier sits, it will wear away if you haven't.

Oh yes indeedy. Aqualube, the best out door, harsh environment grease, I’ve ever used offshore and at sea.

The sun came out, briefly, got out on the bike. I didn’t think the Cush drive rubbers were bad, but changed them anyway seeing as how I’d already bought them. What a difference. Much smoother ride now. Well pleased.

So do you pack the area behind the sprocket retainer where the bush lives with Grease Oddjob? Or just smear grease on the mating surfaces? (I’m not yet that familiar with the 500 rear hub as I’ve always got other to service them for me, but will need to be soon :-) ).

It's just the mating surface that needs it James, you don't want to much in there as the cush rubbers live there as well and grease can affect them, as the cush drive moves back and too under acceleration and engine braking you need to ensure the two surfaces aren't wearing themselves away, it's a Goldilocks amount, not too little, not too much
