View Full Version : cog welding with rust

Maybe kind of a dumb question, but I'm the worst for maintenance, and I can't see myself taking off the cog/lockring every once in a while in the winter to regrease it to avoid weldage. I'm putting another on now, and not even wanting to consider the state of the lockring and cog after just a few weeks of regular salting and wetting. rusty steel cog, salt/alu reactions on the hub threads, hmm.

You all in the salty wetter snowy areas, can I get away with just leaving it on there all winter and still get it off in the spring? the threads were greased to the wazoo when installed, and while I can't imagine much can actually get in between threads there, it seems that much can't come out either.

Then again, salt has an amazing way of finding its way into everything.

Does anybody besides me use anti-sieze compound on threaded parts? This is the stuff made for automotive use that is silver or copper in color and gets EVERYWHERE. However i use it on large threaded assemblies on my vehicles that I know I will want to be able to take apart after years of salt-attack and zero maintenance. And they always do. Come apart. This stuff is the shiznit for big suspension bolts, etc that would really suck if they got frozen in place.

I used it on some bike parts but I haven't been using them very long and I don't like riding my "good" bikes in wet winter weather so I don't really know if it works or not.

Water can eventually wash the grease out of threaded assemblies to the ponit where corrosion takes over. I think it takes a long time though.

In retrospect I guess these comments aren't really that helpful. Oh well.

I haven't had a problem with cogs or lockrings, at least using the rotafix method to get the cog off. Lockrings, it really pays to have a better tool (I use the Hozan wrench) to make sure you don't strip them.

One thing you really should check though is the seat bolt. I had one of those seize on me last winter. It loosened enough to let the seat move forward and back, but I couldn't tighten or loosen it. When I finally got it off, I found all of the threads coated in a really fine powdered salt. Basically it had welded all the parts together and stopped any threads from engaging. The only thing really holding it together was salt cement :mad:
