Deraillier gurus - anyone in the know?

[117]

I have a question for the guru's out there on mtb RD's: 

 

I have an XT M8000 (11spd) RD. Now Ive gone and stripped the thread for the guide pulley bolt (top guide wheel). Sure, its easy enough to re-tap the thread, but, I also have a spare cage system from a SLX M7100 (12spd) RD. 

Now the clutch systems are exactly the same between the deore, slx, xt and xtr systems for the past 3 generations of RD's. I would presume then that the mounting system for the cage's would  be the same too? 

Ive also checked the DM RD004-08 manual vs. the DM-MARD001-02 manaul but I cant see any decent views to see if theyre compatable. Short of me trying to do the swap and actually testing - (which would mean I wont be able to re-assemble the xt cage before it gets repaired.)

Are the xt 11spd and slx 12spd cages interchangable? I would also prefer an over sized pulley system anyway

Muchas gracias

I have had a go at swapping out the RD cage on a clutch type deraileur, but I gave up when it started looking difficult (looked like I was going to struggle to get the clutch off). Maybe you can find some instructions.

I have however swapped cages between other deraileurs on a number of occassions. I can't see the 11s/12s thing being an issue.

Not sure on the compatibility between SLX and XT. But it should be pretty simple to remove. With the older xt m786 clutch rear derailleur I've managed to rebuild the whole cages across from one derailleur to another.

Should be able to take the two cages off and check pretty easily

Its simple enough to remove the cages/clutchs, but I'll get stuck with the xt cage to put it back as I dont have the tools to repair the cross thread for the pulley wheel

Take the outer plate off both and check the shape?

The most important thing would be the orientation of the spring hole.

Then just pop the cap, turn the clutch 'off' with a 2mm allen key, swap out the cages and then turn it back on. Close the little lid and boom!

for the broken one, I've succesfully put a slightly longer bolt through with a low profile nut on the end, all loctited into place. Probably done about 10 000km with it like that.

But that is on a Shimano 105 RD.

Thanks Jewy and Chris. Great info. I'll check it out on the weekend and get back to you with a result

Problem... 

The xt cage has the spring hole here where the 2 red dots are. The slx spring hole is inline with the longitude of the cage. Its easy enough to drill a new hole I guess, suppose its also easy enough to find new stock somewhere (hint hint, any suggestions to look local?)

Eish... I tried drilling a hole once to put a long cage onto a road derailleur. It sort of worked but wasn't perfect.

I am the wrong person to ask.... Only 1 of my bikes has a derailleur on hahaha

Lol, thats the truth right there!

Thanks for the tips though Jb,
