Cranck bearing

asaf123098 · February 2017

Hi, when i pedal my cranck bearing makes noise, does it mean it wore out? Or does it just need to be re greased?

And also, is there a good grease i can get on ebay?
Thanks!!

It depends on the bottom bracket. Most are not really serviceable.

What bottom bracket? What Crank?

Is it the bottom bracket or a pedal bearing (hard to tell apart).

Hi, im pretty sure its the bottom bracket, my pedals are hardly one month old..
As for the bottom bracket, im not sure what it is.

This is my bike:

The bit that goes through the frame that the cranks bolt on to. In your case a Shimano Octolink. You'll need the right tools to remove the cranks, and to remove and fit the new BB.
BB needs to be the same axle length as fitted.
Unusual though, they normally last for ever. Unless jetwashed..

My bb es30 octalink creaks and it's brand new, I thought maybe the half splines are the issue as the crank arms don't ultilise the cartridge fully, seems like a bad design.

I use marine grease, it stops water getting to the bearings, you could always try greasing it up and refitting it, one of the crank arms might have come loose, it's worth a shot.

It actually makes sense that i might have jet washed it when i didnt know it might cause damage, anyway, i think ill take it off, regrease it and hope for good,
And as for the grease, could you maybe send me a link to ebay for that?
Thanks for your help!!

It might be too much damage has been done if it's been run with no grease in it, so just get something cheap, standard bearing grease from Halfords or local motosave.

Or of you want a better grease something like this
