Crank bearing noise

[wa-wil-jy-wees]

How. do I know if my crank bearing is going?

<?: prefix = o ns = "urn:schemas-microsoft-com:office:office" />

 

The last few rides I had, it sounds like something is clicking on the inside of the crank. I have lubed the pedals since the local cycle shop said that the pedals bearings might be dry. The noise is still present.

 

Any advice please?

Hi there,by crank bearing do u mean the bottom bracket?Usually a clicking sound is sign of a worn BB,you would have to replace it or service and clean it ,depending on the type of BB and/or condition..

The only way to say for sure without opening the BB up, is to remove the chain, spin the crank and put your ear against the frame somewhere. You'll here a shhhhhhh sound for a healthy bearing and a rrrrumble for a sick bearing.

 

Click sounds come from dirt trapped between BB and BB shell threads. The only cure is to remove, clean, apply whatever muthi of your choice and re-install. It may or may not return again, depending on what dirt gets pulled in there by the water.

 

Poor bearings don't cause click sounds. Clicks come from healthy or sick BBs.

Also check that the cable for the front derallieur isn't hitting the crank arm as it passes can cause a clicking sound.
