Hmm have I damaged my rear hub??

[silentRVF]

Take the chain off and spin the hub..you then know whether the chain is at fault.

Yep it makes noise when I do that.

Then unbolt the rear caliper and spin it..are you sure the brake is not binding?

I haven't done this but I know the brake isn't binding.

Then get a 46mm socket and get it stripped and re greased....easy!

Holy shit - 46mm? I had problems finding a 36mm socket for the rear wheel nut!!! I might wait a week and let my mechanic sort it out. Hopefully the 60km ride there doesnt damage anything vital!

What is the rear hub outer bearing and could this cause these sorts of problems with making the wheel hard to move in certain spots and causing the chain to be slightly tighter in some spots than others?

You could have killed the bearings but they normally rumble and make nasty noises rather than nip up

hmmm how about if I used this much kero + degreaser, plus about 3-4L of warm water with caustic washing powder??? hahaha

46mm socket and large circlip pliers reqd also the caliper mount can also seize onto the hub giving problems as well as sticking pistons as cmsmj1 said get it stripped and regreased well worth doing as part of general maintainence anyway on these bikes.

Yep might leave this for my mechanic and get them to regrease everything in my hub. Hopefully if the bearings or part of the hub need replacing it won't take them too long and they will have the parts needed!

Cheers
PS: Replacing my rear shock with an aftermarket shock and setting up for mainly road use shouldn't take them more than a couple hours, right? They work on these bikes every day and know them inside out.

Dude..they probably won't have the hub bearings in stock and when they do you'll choke on the price..

£40+ over here..

Swappign a shock is a piece of piss. You can do it in 30 mins if you have the bike on a decent stand (pegs or abba stand)

2hrs!! I would want my hub bearings regreased, all my linkages cleaned and greased and the shock in and sorted in that time.

The hub bearings are large rollers that need to be strong as they locate the wheel in the straight ahead. It is vital they are good as a single sided swinger needs solid support. Imagine if the bearings collapsed and the rear wheel was rocking or even locked up? Nasty.....

SO, don't scrimp on this mate..it is as important as any fancy bits and IMO, even more so.

A bike that works perfectly is better for you than a pretty one. Both is good!

OK well I'm not confident enough, I dont have the tools and TBH I CBF fucking around any more on this bike, to do this. I haven't ridden it since I've noticed this problem even though the weather's been perfect and I'll continue to do this until my mechanic opens.

When they do open I'll get my new shock installed and sorted, get them to check, clean and grease the linkages and disassemble and grease all hub bearings (and replace if needed), as has been suggested here.

That Koyo RS6908 I think it is (the double bearing used in the NC24/30/35 hub) is around £65 in the UK.

David Silver Spares regularly stock it from Japan at £25! :-) They have one in stock right now.

Dont' use kerosense / degrease near your rear hub. Use it sparingly on the chain.

Penetrative liquid (gasolene is worse!) will get through / around the rubber seals, even easier if they are worn and remove / dry up the grease in the hub / chain.

When it dries the system runs dry and everything grids to a halt, siezes up and dies. When using harsh chemicals, if in doubt dont' use it, otherwise wipe with a cloth / fine brush and rinse with plent of low pressure water, this will not get past the grease.

A pressure washer will.

1000kms on an incorrectly adjusted chain is more than enough to ruin the chain.

Hopefully your bearings are not killed by tight spots / excessive force on them too.

[silentRVF]

hey Neo thanks for the reply. Thankfully I took it to RB Imports this morning and they took the rear hub off, cleaned all the shit out of it, regreased it and it is alot smoother now.

There are no tight spots in the chain any more, so it must have been the bearings playing up.

Cheers!

Good stuff! The best thing when anything that rotates becomes stiff is to look at it sooner than later otherwise you risk expensive damage, fortuantly it looks like you didn't do any damage to the bike :)
