Help! Derailleur pulley lubrication

OakLeaf2010-04-29 00:20:29 +0000 #1
Well I pulled my derailleur apart so I could thoroughly clean my chain, only to find out that I've got ceramic bushings in one of my jockey wheels, and I don't know what kind of lube to use on them.

I wasn't expecting that - I thought both pulleys were sealed bearing and I could just clean around them as they probably don't need re-packing yet. But the whole thing came apart.

I sure would like to reassemble everything so I could go for a ride tomorrow! I don't have any bicycle-specific grease, so Deb or whoever, if you could specify the composition of whatever grease I need to use (moly paste, white lithium, etc.) that maybe I could get from the auto parts store, that would be a huge help! Thank you!

Just checked Barnett's manual and they reccomended light grease. I have used white lithium grease used for engine rebuilding. It is a very light weight grease that doesn't get thick or sticky.Can't think of anything off the top of my head right now that would be similar.

boy, a stop by your friendly LBS might be in order. they know what to use, they use it all the time. I don't think Deb's been by today or she would have surely answered!

If you haven't already done this , I would check with your LBS. Having installed ceramic bearings in a number of bikes, I have found that some do use grease and some do NOT! It really depends whether it is a true ceramic bearing.... does it have a ceramic or steel race AND ceramic bearing? Did it have or appeared to have grease on it when you pulled it apart?

Good luck!

I did see the question, but didn't know the answer. I've never used ceramic bearings, and a quick web search turned up conflicting advise.

So thanks for the enlightenment, Ridebikeme! After my UBI course this summer, maybe then I will know EVERYTHING???
