Shimano Reinforcing Pins

[Rob500]

Evening All.
After learning from another thread about chain wear & stretch I checked mine and found it needed replacing. I'd appreciate any help/advice with the S-R-Pin. In these photos you'll see that it looks not bad from the front but at the back there is a slight protrusion.
1. Is this ok and I've just not nipped it close enough at the back?
2. Have I've pushed the pin through too far and its use is limited?
3. It's of no use and needs replaced rightaway. If so, can I put another S-R-Pin there?

1/2 Dunno, but I'd just ride it.
I don't think there's any choice about how close you remove the guide section of the pin - it only breaks at the designed point.

3. You can't push the connecting pins out like you can all the others. You have to break a chain anywhere other than at a connecting pin, as pushing one out damages the sideplates so a new pin won't grip.
If you do decide to take it out, also take out the pin at the other end of the outer sideplate and use a SRAM, KMC or Connex powerlink to rejoin it.

Thanks Andrew. Think I will just ride it and see what happens. I do carry a few 9spd KMC links in my saddle bag if ever I need them. Should've used those in the first place. Guess I was thinking, "It'd be good training to learn how to this the less easy way".

Check if the chain rotates freely on the pin. Some times if you don't push the pin far enough (or too far) you end up with a stiff link. Also try back pedalling and watching the chain as it runs through the deraileur. If the chain jumps or catches then you have a problem with the position of the link. If there are no problems with stiffness then I think your pin should be okay.

FYI, next time buy a KMC chain as they are superior to Shimano chains in every way and they connect with a missing link, so dead simple and no tools required
(unless of course you need to adjust the length of the new chain), but regardless, Shimano chains suck IME.

Shinano chains do indeed suck.

As above. Avoid Shimano chains.

Shimano chains are absolutely fine if you use a KMC "missing link" to connect them. There's a massive review of chains in this magazine which rubbishes the myth that Shimano chains suck

That "link" doesn't work.

That "link" doesn't work.

Actually, it does work, but the one in your quote doesn't (missing the "e" in "epaper").

Here it is again (Page 44 for chains test)

Interesting magazine. Thanks.

shimano chains are perfectlhy fine and the pin is fine too.

from the photo is does look as if the pin sticks out a bit further on one side - if it wre my chain, I would push it bck a fraction so it is same on both sides.

 

[I like Skol]

For what it is worth, I have joined and rejoined many shimano chains without the special dedicated jointing pin.This has never resulted in any untoward consequences and I am far from a low power rider, I do put some high torque through the drive train. IMO, if the pin lines up and passes through the side plaes ok then it is just a question of shuffling the pin back and forth to ensure even protusion through the side plates while making sure there is the minimum freeplay needed to allow a free moving link.

Thanks for the replies Guys. 02GF74, I'll try that tomorrow.

Thanks Oddsos. This is exactly what is happening
