DID X-ring failure (again!)

ThunderGuts · World Chat Champion Joined: 13 Nov 2018 Karma :

When I was cleaning the chain on Saturday, usual routine (spray a bit of paraffin, then use a Muc-Off chain brush which is nice and soft, followed by a microfibre towel to clean it down afterwards, then lubed). Noticed on two links (not adjacent) a bit of rubber X-ring was poking out of the link, indicating they've torn/failed. This is the second time this has happened with the Crossrunner, but I figured the previous chain was neglected by the previous owner. This chain has been on for about 2.5 years and has only covered about 7k miles, most of which are fair weather.

Am I doing something wrong, or is this a fact of life? I know I can just keep lubing it and it should be fine, but it's still a bit irritating when I hear stories of people having chains last for 20k miles or more.

I'm going for a reynolds o-ring chain next time on my VFR. I put one on the bullet this summer after the side plates on the swift x-ring it had fitted started splitting through the pin holes. They are seriously chunky, no fucking about chains and relatively inexpensive to-boot (like under £50).

Only available in "imperial" sizes. but 5/8" x 3/8 " = 530.

If I started again I'd probably go for a shafty, but I'm in too deep with the viffer now for it to change! I've looked at Scottoilers on and off over the years but they've always come across as being a bit faffy (getting the flow rate set correctly etc..) and given my bike is mostly a fair weather toy (I don't commute on it, the only time it experiences rough weather is if I'm touring, again that's pretty infrequent, once or maybe at most twice a year).

By rights, the O rings between links should be nitrile ( compatible with oils), maybe there are some oils/ lubricants are more aggressive to the the rubber.
Even on some of the machines I work with, rubber components are not as flexible as when new even after a short period of time.

I suspect the paraffin is rotting the x rings WD40 dose even if the makers say it should not

As above: Paraffin rots some seal materials.

I once used paraffin to clean some engine o-rings. The next day they'd turned into a sticky mess.

Do not put paraffin on chains.

Is the failed x ring on the soft link?

Fit a New Chain (possibly sprockets) and a Scotoiler.

End of thread.

Much like a sprint but it's doable. It's all about the positioning of the delivery pipe on the swing arm so that it's as flat as possible and doesn't move with wind pressure.

If you can't achieve that, a shorter delivery pipe so it's on the sproket much higher and basically slung onto the chain.

I have seen the same situation on the newish DID X ring chain on my Exup-R.I do not use a brush to clean it,or parafin.It has only occurred on one link,which was not the soft link.The back wheel is in alignment and the sprockets are both Renthal.

I have the same specification chain on my 5JJ-R1 and my 3XW-FJ,which are both doing okay.

I would have to look up in my records as to how many miles the Exup-R and 5JJ-R1 have done since fitting the new chains and sprockets,but I do know that the 3XW-FJ chain,again with Renthal front sprocket but a steel rear,has only done around 3,000 miles since fitting back in 2019,just before Mrs.Fizzer and I rode down to Italy,in all weathers.
