Posts: 131 Ohio Gender:	Chain conversion gone wrong--eating through metal 11/04/22 at 10:49:03 Well I guess I'm glad I didn't go for the 13/50 combo. With the 14/50, the chain is already eating through the bottom of the RYCA footpeg relocation bracket (see pic). Not sure if I should let it eat, try to take it off and fab something (like a recess), or epoxy some ABS plastic. I'm open to all suggestions.

Ah figures. I've tried calling RYCA several times, but they don't return my calls. Now that they are some fancy computer software company, they've completely washed their hands of the parts business. The one time I did speak to them, they told me they sold all their parts and designs to another company, but when I tried to contact that company, they were out of business too. Seems like if you need RYCA parts, you're screwed.

The chain is cheap (Caltric). I'm half thinking I'll just let it eat it's way to freedom lol

Scared me and busted up my new paint job when it snapped. I don't understand why it snapped. It doesn't seem to have wear on it from rubbing the frame. The teeth on the sprockets all look good.

The only thing I can think of, is that the chain came with two different Master links:

One master link had a clip, where you just push it through, put the other plate on and clip it securely. The other master link, was the type where you need the special tool to flatten that rivet.

I'm realizing now that the chain plate I have does not fit on the master link that is rivet style. I wonder if I put the chain plate on that head slightly larger holes in that somehow led to the chain busting.

Is this chain trash? Or should I just get a new master link? Does the chain snapping indicate I probably did something wrong, or that it is garbage quality?

Another hypothesis:

When I cut the extra length, I didn't have the pin tool, so I used my angle grinder to cut the link all the way through, and then grind down the pin. It got so hot the pin just slid out.

I also noticed a faint grease smell when riding, but I figured it was the new chain.

Could I have overheated my o-ring chain, and then it broke a seal and bound up and snapped?

EDIT: I'm a moron. I didn't grease the master link when I installed it. I'm guessing this led to excessive heat and/or binding. I wish I wasn't so dumb

Also, slack was 7/8, then I adjusted to 1.25"

The chain and sprockets are definitely a safety item, and it is never a good idea to use "cheap" parts for safety related parts. You got lucky. A chain break while riding can cause you to lose control and crash, which can result in severe injury or death. Get a top quality chain, buy the proper tool, and install it correctly. Or, if you are a risk taker over a few dollars savings, keep doing it the way you have been. It's your life.

I agree; I have a wife and little kids, I gotta play it safe. I guess I shouldn't be shocked an eBay chain broke after 20 miles. I ordered a JT x-chain and a breaker/rivet press tool set. I should've known when the Caltric sprocket had sharp pieces sticking off from casting. I had to file it down.

I'm lucky that chain didn't wrap around the rear axle and lock it up. Shocked

Thanks for the specs. This is what I got so far (pic below). Is there any harm in leaving it open? I'm only 150lb, so I can't imagine it'd be a structural issue.

I have only thin metal to weld in, but there's not much left to box in anyway.

IDK what cutting board plastic is EXACTLY, but the white ones are tuff. The one I picked up outta the road served in several places. First thing it did was to get put on the legs of a workbench. But I suspect it would take a fair bit of chain dragging across before it was gone. Depends on how much pressure is involved.

IDK what the tool that mushrooms the chain to keep the plate on and orings snug has to be made of. I used a panel cutter with a hammer insert, one I made. And someone holding a hammer for backup.

As far as the chain, use a masterlink that clips. Make sure to orient the clip so that it is pushing itself on, in the way it travels. Not mounted so that anything it hits will knock off the clip.

Rivet masterlinks are a crapshoot if you dont have the right tools. Just stick with the correct size clip one.

That chain doesnt look broken, looks like the master just fell out.

I dont know what series your running. 520, 525, 530 or what.
