Last weekend the mirror this weekend the Hub

Tried to go for a ride this morning got to the top of the Mountain and the back wheel felt strange. So I gave it a shack and it was moving the rear ball bearing race has collapsed So I have spent the afternoon pulling the hub and bearings out which is far easier than I had antisapated. I found that the ball race is plastic inside is this why they self destruct, I would imagine that there would be a lot of heat generated from the Brake disc which is mounted next to bearings on the axle.
I hope this lucky streak ends soon

Sorry to hear this. I doubt its the brake heat thats caused the bearings to fail though. I rarely use my rear brake and my bearings went too, lots of threads on rear hub bearing failures here I'm afraid if you want to check them out.

Yes thankyou

I had a look and have found Bearings localy using part numbers from the thread and I hope I am getting the Ball bearings with a metal race not plastic like the original one. It looks as if it just fell apart and there is some signs of heating.

Lorne910: 1. How many Km on the rear hub? 2. How many Km since hub was last disassembled and lubricated?

Thanks,
Dick

It has under 11000km and as far as I know was due for hub maint at 12000km but the bike is over 3 years old I got it with 2000km on the clock 18 months ago but it was out of waranty then.
the roller bearing looked great the ball bearings fell out the plastic bits had come apart and it did seem very dry.

chain slack

Was the chain recently adjusted? They do not like to be to tight, better to the lose side.
