Broken Chain
« on: May 26, 2012, 05:48:59 AM »
Yesterday on my ride home from work I noticed a clunking sound from the driveline...! As I slowed down to inspect it, a loud one time clunk and nasty bump made me nearly s%$t myself. Once I stopped and inspected the chain, I found that the masterlink has failed. The weird thing is that the clip side didn't fail. One of the posts had pulled out of the back of the link! The plate had rotated around and was clunking on the case. I was lucky enough to be close to work, so I took the link and post and walked to the machine shop. I put a little spot weld on the back of the post and limped it home.

My questions: first of all, why would that link fail on the back side? Has anyone else experienced this before?

Secondly, I now have bought a rivet style masterlink..Any advice on which rivet tool to buy? There seem to be a plethora to choose from!

Cheers,
KC

The chain failed because it was OLD.

It was not because it had a master link.

KC,

Check the tools sub-forum from the main page.

Several topics there similar to this one:

While on the topic, is there anything 'wrong' with c-clip drive chains? Or should you strictly use a rivet type?

Nothing at all wrong with 'fish' clip particularly as most are now made so side plate is interference fit.
Sounds like you had a badly fitted rivet link?
I've seen it done several times when people didn't have correct press/rivet tool and didn't understand how to use a couple of hammers.
Chain only needs to be slightly out of line and/or too tight to cause major problems

I will say this again.
There is NOTHING WRONG WITH DRIVE CHAINS with clips.
They have been and still are used extensively in the motorcycle world and are completely reliable.


When you drive on the freeways what do you see?
Thats right Broken rubber drive belts!
Have you ever seen motorcycle chains laying on the ground? NO.

I will buy regular chains with clips until I die.
They are reliable.
They are sold all over the world.
The are easy to take off and put on.
NO SPECIAL TOOLS NEDED.
With modern chain lubes they are no longer a problem.

You do know the one that failed had two rivets on the back and a clip on the front so now you have one with four rivits. Kind of odd you are worried about the rivit and you increase the number of rivits ::) ::)

"I will buy regular chains with clips until I die."

With all due respect, do you hear yourself?  When one takes a position like this one relegates oneself to the junkheap of outdated technologies.

We all know what your position is on this. So I leave that be.

But suppose something else comes along that truly is superior? You've built yourself a mental barrier to accepting new and improved things. That can only detract from your credibility in this and other discussions.

For example, there was another post where you hung your hat on the "#3 million dollar dyno" that Honda had as being a reason to accept their engineering superiority. Well, its that same Honda engineering that now puts ORing chains on all their streetbikes. So which is it?

In my opinion.  :)

Whoa people!

I just wanted to know what rivet tool to buy. Didn't want to start a life long debate on which style of chain to buy! lol I have tried a clip style, and now know how it failed. Now I want to try a rivet style and see how it will fail and when it will fail.

My clip style oring chain lasted about 2 years of hard riding while being properly lubed! (Pretty good if you ask me) Now I will compare this to a rivet style oring chain.

Frankly, I don't care what type of chains people like to use, because much like a butthole, everyone has an opinion, and everyone's stinks, but nobody thinks theirs stinks!  ;D ;D just kidding!

Seriously though, thanks for the advice everyone. Can anyone suggest a rivet tool that is good for an o-ring type 530 chain?

Cheers,
KC

No idea...sorry!

Sure. So what is my other option? A clip-clip style? ??? lol I would rather just rivet the link myself and be sure the rivets are good and secure. (But good point though  ;D)

I bought this one. I have only used it once, buy it worked.
There were not included instructions, I had to figure it out. The spacers to keep from pinching the orings during installation came with the master link, not the tool.
Through my inattention, I broke the rivet pin (tightened it too tight). I requested from the ebay seller the price for just the pin if available, and they sent me one for free.

I use one I got off amazon, it was actually more important for me to have a multiuse tool that came in a travel kit, as I have too much stuff loose in my garage.

Usual reason the push pins break is the guide section wasn't tight enough so instead of having a straight push, the pin angles slightly and cracks
