So I'm stripping down my mountain bike to give a thorough clean/re-build before selling and I figure I can just pull the FD off like I have on so many other bikes where there is a screw holding the cage together, and I come across this:



I've never pulled this FD off this bike before so I haven't dealt with it, and I'm not finding the old manuals online for some reason. Is there a way to dis-engage the small spring and have it pivot away to allow the chain through? Or is there some other way to do this? The FD is an XTR M95X (haven't cleaned it enough to find/get the last digit, it's one of the top pull models, not that it should matter).

Thanks!

Looks like squeezing the sides of the cage together at the back will release the other side and let the spring pivot that piece out of the way.

<I Guess its a Rivet> you're boned .. open the chain at the quick link and take it Off that way.

Ive never seen any .. Not an XTR Fitted MTB ridin' guy.

It's been a long time since I had installed this chain (not much riding on the MTB since though), I'd forgotten that I had a quick link on this chain.

Still though, what is the purpose of that spring and the apparent hinge? Both sides seem to have a pin that do not look to be removable.

Ask Osaka ? the designers are there , Maybe a Shimano Factory tour can be arranged?

I <guess> you mean the return spring that opposes the cable pull.. that is how it shifts both ways.

what hinge?

You may have to take more pictures or wait till another owner of that exact part chimes in .

I , guessing again , the ends of the piece was formed to wrap around the rivet pin , you only think its a hinge, but it's not.

The spring I'm looking at has nothing to do with the cable pull. It's at the end of the cage typically where there is a screw so you can remove your chain at the tail of the cage. Here is a better picture of the spring in question, and a picture of the front side of the link. I read someone's review of this series that speculated that it was there to help with chain rub in some way, but that seems a little strange as it doesn't move much and it's at the bottom of the tail of the cage.

Back side of the cage at the tail:


Front side:

Too many Bells and whistles then .. Good Luck .. Those Shimano Engineers need their Boat Payments.


Left friction shifter, I just move the cage with it and have never worn thru a FD cage ever ..

at least you got the Master/quick link part of the question.

It's a hinge. The two side plates of the cage move independently.

Yea,as I said in 3rd post , You're Boned , open the chain..

check it for wear, May be done.. and you need new chain+ new Cassette.

I'll open it once I get some master link pliers. The shop near my house doesn't have stock (they seem to lower their stock of tools in the winter when people have time to work on bikes). I'd already checked it for wear, the .5 end of the chain checker isn't even close to dropping in. If it was toast I would have just pushed a pin out and tossed it and not worried about any of this.

fietsbob

Try This : rear Wheel out so Plenty of chain slack .. fold the chain in a U where the quick link is, and squeeze the rollers together with a needle nose plier.

though someone into XTR stuff may feel better with the Perfect tool ..

There was a recall on Sachs chains. CPSC, SRAM Corp. Announce Recall of Bicycle Chains | CPSC.gov
You might want to check that.

Thanks, I've seen these methods and would prefer to add a tool to my tool box that I can use for my other chains.

Thanks for the link. Date codes don't match the recall.

I was annoyed when I figured out it's not possible to do this on most derailleurs. Shimano also makes it harder than necessary to take off a rear derailleur without breaking the chain

HillRider

All you have to do is remove the bolt that holds the lower pulley. That's the same for nearly all rear dérailleur.
