manuels61 Posted September 17, 2020 Share Posted September 17, 2020 So anybody else running an xt 8000 rear D with clutch that seems to be working itself to off position after a few jumps/miles,?? It’s at least 1 1/2 tears old and six months ago the switch for the clutch broke off, I noticed the clutch before doing this so got new one rebuilt it and thought maybe this would fix the broken and the slipping of the clutch but it has continued to drop to off position usually after only 5-10 miles seems to be getting shorter, anybody come across this? Any fix before I just buy new drive train? ,, ps. I only need one person to say no! buy new, can’t be fixed so I can justify this to the wife!

RedRider3141 Posted September 17, 2020 Share Posted September 17, 2020 (edited) I have an XT M-8000 11spd. Honestly I regularly forget to turn the clutch on but when I do I've never noticed it turning off. Is the lever moving, or is the clutch releasing? Mine is ~4 years old.

mack_turtle Posted September 17, 2020 Share Posted September 17, 2020 the clutch is adjustable and needs to be touched up every now and then. look up the service instructions for your derailer. Quote Link to comment Share on other sites More sharing options...
manuels61 Posted September 17, 2020 Author Share Posted September 17, 2020 The lever is actually moving to the off position not completely but I think only because I usually catch it especially now because I’m constantly looking to see how much it has moved, mac like I said I replaced the lever a couple months ago and serviced the whole thing and have everything tensioned right Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
mack_turtle Posted September 17, 2020 Share Posted September 17, 2020 without seeing it in person, I certainly can't diagnose it. depending on how much you ride, I'd think it should last longer than that. Quote Link to comment Share on other sites More sharing options...

Until I recently sold a couple of bikes, I ran XT RD-M8000 on 4 bikes. I still have it on 2 bikes. I tend to get about 4000 or so miles out of them until they just wear down or get bashed enough to stop functioning. I keep a lot of the spare parts, so in an emergency I may cobble one together. But I also always keep a new on on the shelf. They're only $80, after all. So I'd venture to guess that I've bought quite a bit more than a dozen of them over the 6 or so years that I've been using them. And in all those I have encountered 2 that have had issues that I've managed to warranty. The first one sounds a bit like yours, but it occurred on a new derailer. Oddly the clutch didn't lock on. When you engage the clutch, it didn't "click" into place. It flips to roughly the on position, but it doesn't stay engaged for more than a few minutes of riding. After a couple of minutes, it is full flipped into the off position. Fully tightening or loosening the clutch didn't help the situation. And when I pulled it apart to look at it, the little friction cam that was supposed to hold the clutch lever in place just wasn't doing it's job. Jenson sent me a new one. The other issue occurred with one after a just few weeks a use. The clutch just stopped returning. It was still very stiff, but it didn't actuate back once it moved forward. Odd. I didn't bother to break this one down for diagnosis. Jenson sent me a new one. 1 Quote Link to comment Share on other sites More sharing options...
manuels61 Posted September 17, 2020 Author Share Posted September 17, 2020 Thanks Barry that’s more than likely my prob, I am not getting an obvious click to lock it in but it has had its share of bruises and is at least 2 years old so just time for some new stuff [emoji3] thanks buddySent from my iPhone using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...

I'd buy the 8100 just for the better design even if you're gonna run 46t. IMHO, hard to beat the MX8 series sunrace 11-46. Fairly light considering, and plays well with OEM and doesn't have the stupid 37-46 jump like the shimano cassettes. Here's the place I buy my shimano & sunrace and various bike stuff for a good price. https://www.lordgun.com/ Edited September 17, 2020 by ATXZJ 1 Quote Link to comment Share on other sites More sharing options...
Trailrider Posted September 17, 2020 Share Posted September 17, 2020 I'll give you some cash for it if you want to offload. I have one that needs the lower cage replaced. Quote Link to comment Share on other sites More sharing options...
