Spare O-rings for chain?

Post by Colorado Mike »

Like a dumb-a$$ I lost one of the o-rings on my master link today. Does anyone know if bike shops carry spares ? Or maybe it's a common size that I could get from Home Depot.

Also, has anyone found a good chain-lube that doesn't attract dirt? The PJ-1 I'm using is a magnet for dirt.

Thanks,
Mike

Mike, I don't use any lube on my O-ring. All the lube the chain needs is already inside, sealed by the O-rings. All I do is spray the chain with WD after a wash to get the water out. For a real cleaning, I soak it in kero, brush with a parts brush, then wipe off with paper towels.

You'll proly have to buy another Master link to get a o-ring. I use that Chain Wax... seems to work pretty good.

Have you read anything about dry film lubricants? I would suggest some lube even on ring chains because they need lube between the plates, too.
Thank you for participating on kdxrider.net. :bravo:

I'd take the one remaining o-ring down to your favorite megalomart and match it to the closest size in the o-ring case. Should be all of 20 cents.

Good advice! :prayer: Last time I changed chains, I too lost one of those little critters on my garage floor. :? Actually, it's not lost...it's in hiding, and one of these days it'll show up...one day after I desperately needed it. :shock: Luckily, I found a replacement in an old O kit I bought years and years ago.

Just one more reason to buy that "spare" master link for including with your trail tools. They come with O-rings that can be borrowed as necessary.

I carry a spare in my fender bag.

...don't carry a chain breaker, though..so don't ask me what good it does to have a spare link.

Go to your local bike shop and ask if they have some lying around. They probably do. If not..you're stuck getting a master link which should come with rings. I sahy SHOULD because you should make sure it does. I got one that did NOT have any o-rings in it once. Seems someone had 'borrowed' them for use somewhere else. Ended up ordering another one.

re: hardware store:

Last time I was there, I looked for the RK X-Ring drawer...but missed it! :roll:

Point is...I wouldn't count on that. Size is going to be critical. It's hard enough getting the things squeezed together correctly WITH the right parts..lot alone one that's a bit fat.

Besides, is the service application for o-rings on O-Ring chains anything like your one-each HW store variety? I dunno...maybe it is...but I wouldn't bet on it.

Is it really going to hurt anything if you don't replace it?

I ran my master link without o-rings for about 12 months before I replaced the whole chain and it was still going strong.

Did it groove the heck out of your chain guide? I would think the master link would tend to float one way or another as the chain made its way around the sprockets until it got to the chain guide.

Probably groove it a lot less...AND have less wear on the clip than it would WITH the o-rings on it.

For whatever reason...the chain guide being (whatever it is) and the master link being metal, you'd think the chain would wear a groove in the guide and you would be done.

But...no.

I've replaced clips more than a few times when the chain was fine..but the clip was ready to fall off due to it getting completely worn out rubbing on the guide.

I went to the shop and picked up a master link set that came with the rings. The counter dude just wrote it up for $.99, which was a nice discount over the $4.50 they normally sell for. So far I've spent close to 5 grand in there, so them discounting the link made me feel all tingly inside. :wink:
