Just put a new t63 on last night and noticed that the bearing that is in the rear sprocket carriage was collapsed . This is the same bearing that collapsed on the NIIS ride and chewed up my swingarm etc andthat embarrasingly meant I had to get a ride home on a trailer.
Does anyone else have trouble with this bearing?
My advice is to check it as it is often overlooked when removing the rear wheel etc as it is in the sprocket hub which often just gets put aside and not seriously looked at.
I mentioned vegetables once, but I think I got away with it...........
its got something to do with you being an animal...
I suspect worn cush drive rubbers can increase the loading on the bearing.
I replaced the bearing on mine (and cush drive rubbers) at 25000km just because of what happened to you.
the new sealed bearings sometimes don't have much grease in them so its best to pop the seals and repack before you put the new one in.
I used to think sealed bearings meant that I can ignore them but I have had to many die on me to not try regular regreasing.
Is it on the downhill side when the bike is on the sidestand? That side bearing always suffers more.
Get new seals *and* new spacers for them to seal against. Worn, grooved spacers don't seal.
Don't over-pack the bearing with grease, they are designed to run with only 25-30% of the void full of grease. IME they'll just spit the excess out even though they are only running at 10% of their max rated rpms. A little but often is the trick. River crossings are particularly bad for wheel bearings.

Part of the problem I now suspect with this one is that a heap of the hub got worn away when the first one collapsed and now does not have the protection it should have. A stick or something may possibly have got to the seal. It is not hard to change and they are a real common bearing, and I now carry that one in my toolkit.

Generally, I agree with you, but for wheel bearings they get compromised much worse by contamination. Use a small pocket knife to get under the seal, and just lever it out. It will pop out without damage even though they flex heaps as they come out. Don't slide the knife as you could cut the seal.

I swapped some labour for a few boxes of KLR parts. They're from an old white, green & blue model so if anyone needs any parts sing out cos after having a good look thru I'll start getting rid of most of it on Trademe.
I have alread scored a carb diaphram ($95 US last time I looked) & an unobtainable front sprocket cover so it has already paid for myself.
Unfortunately most of the motor internals aren't there which is a pity as I would have liked to reassemble it to see how it all works.
So no wheels. bars, frame but lots of electrics & plastics speedo etc.

I don't know what model it is in fact I realise now how many parts a ren't there...
Tank was rooted & rusted threough so went to the tip with the PO
Yep the speedo is there reading 86K with spre speedo cable. Seats there but may keep that.
I will take everything out of the boxes in the weekend & take a few pics so you can see whats there & the cond.
It has a very cool rear RHS melted exhaust shroud.![]()
