    SRAM XO shifter difficulties

    I just dissasembeled my XO shifter to replace the cable, and the springs popped out of place. The screw on the carbon side of the shifter wouldnt come off so I had to remove the cover on the oppostie side aswell. I found out what the carbon side spring setup should look like by removing the carbon cover on the other shifter, but I couldnt manage to get underneath the bottom cover to get a peek at that. Im not sure how the lower/non carbon side spring should sit, or how I should reassemble it. Let me know if you guys have any solutions/picures for my problem. Thanks

    Every so often I see these threads come up where someone has disassembled their Sram shifter. My buddy took his apart one night at work and it took four of us working at it for two nights before we got it back together and shifting right. He took the other one apart to see how the parts were supposed to go so we then had two to fix. The first one took forever. The second maybe five minutes. This was over a year ago so I can't really help you but I do feel your pain. I will never disassemble the bottom unless absolutely necessary.

    Based on the frequency of this topic I would like to see detailed schematics of the trigger shifter so they can be properly self serviced. I have found nothing on SRAM's website.

    No good send it in

    I just spoke to "technical service" at SRAM for this same issue. They recomended that I take it to a local shop to send into SRAM. The person I spoke to was not willing to help me out over the phone, which is disappointing as I feel that this is something they could have worked with me over the phone on.

    It' s a piece of cake - i took mine apart in about 10 mins.

    To be honnest as i discovered theres not alot to service, all you can do is clean them out and put fresh grease in them however i did find this made a hell of a difference. Mine where full of sh!t but i have used them for nearly 3 years now.

    .

    Uhhh OK, great but not sure how that answers this:

    Let me know if you guys have any solutions/picures for my problem.
    Now if you want to take it apart again and photo document the rebuild process that would be helpful.

    I had issues with my rear shifter.
    Specifically the bottom assembly came undone (my fault, I admit that freely) and I was unable to get get the spring back in correctly.

    What spring in the bottom assembly?

    When you remove the cover you have a spring atop the cable puller. If you remove the upshift lever like i've done you have the inner gear workings and as far as i can see there is no spring.

    Gimme a min - gonna go get the exploded diagram i have....

    Ok so here we have the much longed after exploded diagram of the trigger. Parts 7 apparently are labeled as the X0 Service kit. This includes new bearings and body seals.

    On both of my shifters i removed the levers, and found they were caked with mud - cleaned them and what a difference it made. More on the point i have removed the lever, removed the top and lifted the whole body out before.

    I can take some shots of my shifters if it helps - what bit EXACTLY are you having trouble with?

    Good Lord!!!

    Now I am not sure I would even try to change my shifter cable

    The top cover has to come off to change the cable?

    Well you unscrew the top cover, remove the cover.

    Push the cable out of the cable holder and insert the new cable. Push it all the way through. Put cover back on.

    Done.

    you rock

    Tiffster,
    Thank you very much. I appreciate your willingness to help.

    My mistake was using the allen bolt on the lower assembly, which I thought was necessary to remove the top cover. I think the "spring" on the lower assembly I was referring to, can be seen in the exploded diagram you posted at the bottom of the main shifter body (just above the first part labled "7").


    You are 100% right that changing the cable (when done correctly) is a cinch!

    I removed the allen bolt on the lower assembly too. Holy ****!
    I can't get the lower lever to return to its normal position after I've shifted.
    Unless someone has a great tip I'm taking it to the shop. I spent hours today aking it apart and putting it back together.

    I never understood this - is it only obvious to me that you remove the top cover instead of the bottom allen key fitting?


    Anyway you have probably not located the return spring correctly.

    Yup, i'd imagine there will be some sorta spring which will push the lever back to its neutral position or something.


    If it's that hard to put it back together give Sram a call - explain and you maybe could send it in for one of them to have a look at. Dunno if they'd do that though.

    Make sure you haven't over tighten the "wing nut" on the carbon/top cover.

    T-jib,

    i did the same thing and removed the 2 small allen bolts on the bottom...did you end up getting your shifter to work right again? if so, can you describe the process? I didn't fully take the bottom cover off, but it was loose...I can get the rear der. lever (large silver one) to "return" back to its normal position after the shift....

    Tiffster (or anyone),

    Do you think it's ok or worthwhile to spray a degreaser like Finish Line Speed Degreaser (the stuff sprays on and takes the gunk off, and the solvent just evaporates) when you take the top cover off to change the cable? Your comment about the gunk build up made me wonder if this would be a happy medium between doing nothing and taking the whole thing apart. If so, would you just apply some thin layer of grease with a finger in the body since the degreaser would strip out everything?

    NO!

    Dont spray degreaser in there what ever you do.

    There are actually bearings in the shifter, so you'll strip the grease out of it. And you'd stip the grease of the mechanism and unless you really took the whole thing apart it would be running bare.


    I just cleaned muck out from the underside of the lever between it and the body, there was a build up there and around the seals. Just whipe it off - thats it.

    I've had to do this twice in one year. The culprit is always mud. It gets in and freezes the lever against the bushings. changing cables are easy just as long as you only take the top part off. Finally gave up on these shifters as it takes me a whole day sometimes to figure out how to put things back together again. downgraded to x7's which i think uses bearings instead of bushings. living with them for now. the hassle makes me think of going back to shimano after being a loyal sram user of more than 6 years.

    Can you help us with x.o triggers please? The diagram is cool for x.9 but some of us are having issue with x.o and the design is different on the bottom assy.

    My top carbon plate was loose so I tried to take it off to make sure it was seated prop. The lower assy got loose and popped out. Not I can not get everything back together. If it is so easy can you help us?

    Hi,

    The pic i have linked shows the exploded view of an XO trigger so i don't know why you are referring to X9.....

    How much of the internal gear mechanism has come out? Try and post pics - it helps alot!

    Alright, my bad, but my x.o looks diff than your pic. I am at work but I will post pics later. On you pic you have item 6 (level), then items 7, 7 (washers). On my x.o I do not have 7,7 I have like a coil spring thing that popped out and now it will not go back together. Not sure if I take that coil spring and put it in the housing first then try to put back item 6.

    Thanks for your fast reply and your support it is much appreciated

    Ok so I was wrong about items 7, then 7 (the washers). Those are still on my lever as you can see from the pics (camera phone go easy on me for the qty).


    I know how the unit goes back together I guess as far as the order and where the coil spring attaches to the housing and the lever. My issue is with getting the spring back in the housing so unit works and the washers are flush along with proper spring tension so unit works like it was designed to.

    You can PM me as well if that is easier, thanks again.

    If you remove the silver lever from the part that goes into the body work this might help. It's held on with a 3mm allen bolt - just undo the bolt and turn it and it comes off.

    The spacers go back in with the black going on first then the smaller silver one.

    You should be able to get everything lined up better without the lever being in the way now.

    Dragging this up. Got the same problem: opened up my trigger (X0) and accidentally popped out the lower lever. If I put the lower spring back in (as pictured on supramk388's pics), does it wind down towards the lever mechanism, or does it wind upwards? I had it back together with it winding downwards, but then the lever wouldn't work. Winding it upwards looks pretty weird though. What's the best way of putting that spring back in?

    Winding down it is. Got it back together again. Not too difficult really. Just make sure the toothed gap in the upper spring/cable assembly is above the hole in the shifter itself for the bottom lever to plug into.
