Topic: How do I peen a Tsubaki cam chain master link? (and anyone got pics?)

[ksteve]

Bike: CB750K2
Task: Replace cam chain without splitting cases;
Parts: Tsubaki BF05M 94-link cam chain; Tsubaki BF05M master link;
Problem: Master link is hard-nosed; how to stake/rivet/peen it?

As many here have suggested, I plan to cut my cam chain, split the new Tsubaki, thread it in and re-link it with the Tsubaki link. I ordered several links from Z1:
http://www.z1enterprises.com/ItemDetails.aspx?itemDescription=Cam+Chain+Master+Link+Tsubaki+BF05M&item=TU25-9920.
The Z1 site shows a master link with soft/hollow link-pin tips. So I also ordered a Motion Pro chain tool built for hollow-tip pins.

What arrived in mail has hard-nosed links, not what the Z1 site shows. The Motion Pro tool won't work with these.

I called Z1 tech support; the tech guy said these masters are all hard-nosed, and that the pic on Z1 site is wrong. I asked how to stake these solid-nosed pins; he recommended I split the cases to attach the continuous chain instead of using a master.

I know some of you have put in these chains without splitting the cases and have had good results. Do you have advice and pics of how you staked these hard-nosed master links?

Thanks,
Steve

is this the effect I want to shoot for? (perhaps by knocking the corners with a hammer and drift, if a tool isn't available for our small chains)




or is this good enough?

I don't think there is a lot of force on the side plate They all look fine to me. I would do it myself. Let us see what the pros say.

Have you used this? The site doesn't give much info. It isn't clear whether it can crimp/peen solid pins. I already have one (MotionPro) that can do hollow pins.

I would go with the second pic. It's only to stop the pins sliding sideways. Just make sure you don't press them too far so as to add a stiff link in the chain.

Yeah, I saw that. But the z1 tech I talked with said it needed to be peened, but really wanted me to split cases. So Z1 is not talking with one voice, which leaves the question. If a press fit is official, I'd think Z1 tech guy would tell me that.
