- Servicing and taking apart a Shimano 10 speed Deore XT M786. The first Shimano XT derailleur with a clutch. Couldn’t find the correct term for the cluth mech. It’s referred to as a cam unit.
I just bought a used one. Thanks for the video. Informative!

Damn was thinking of upgrading mine to 8000 aswell will just keep it now it still runs faultlessly.
If ibwas upping the jockey wheels tooth wise from 11 - 11 maybe top 12 - 14 bottom do u think it would be a wise approach? Cheers 🥂
Hi, well if they fit on, I’d imagine you might need to lengthen the chain but it’ll reduce chain slack. So I guess in theory, it could handle a larger sprocket. Though I don’t think jockey wheels allow you to do that. Rather the derailleur design. Can’t think of any real benefits other than appearance and apparently it makes less noise? B screw will likely need to be adjusted but 12t shouldn’t be a clearance issue. Why do you want to do it?
Yo buddy
Think it ticks all the boxes
Current ones are a lil stretched on the teeth
Have a bit of spare on the new chain also fancy getting red ones to highlight the other accents on the bike plus anything that's quieter is an added bonus along with a bit of smoother shifting I think it's my last upgrade since the bikes just about finished 🚲
I have the exact model of your rear derailleur, the issue is that the outer pulley cage is broken which I cant find any replacement, do you have any idea if shimano alivio m4000 or altus outer pulley cage can be a replacement for my deore xt outer pulley cage?
Theres one for sale on bikable for 16,99 euros. Compatibl M786. As for the M4000, looking at a diagram, it doesn’t look like you can remove the outr cage, so I guess no not possible

how did you actually clean the derailleur
Degreaser, soap; paper towels, toothbrush
well spotted
False economy...you should have cleaned it while disassembled
Cleaning it is the easy part nothing false or less economical so relax
