    deore dx thumb shifter rebuild

    does anyone know of a place to see exploded diagrams of older components? i'm specifically looking for one of a deore dx thumb shifter, 7-speed, part number is SL-MT62. Whoever had it before me decided to get clever--they took it apart and put it back together wrong.

    techdocs.shimano.com for the newer stuff. Why not just get current Deore stuff and be done with it?

    There's only so many ways it can be fit back together, there's like... 3 thin plates on the top or something like that, right? I can't recall off hand but the important thing is the tiny ball bearing is what is giving you the indexing by clicking into the little holes... I think the ball bearing is sandwiched between two plates, and then a plate goes on top of them...

    There's only so many ways it can go back together, there's not a lot in there, just give it a shot.

    Those older Deore thumbshifters are soooo sweet.

    I never learned to ride a bike. It is my deepest shame.

    Compared to old Deore DX, current Deore is crap-ola! Old Deore DX has more in common with modern XT than with Deore. Deore DX was built to last... which I suspect is why Shimano discontinued it.

    For what it's worth - I have the exploded parts diagram that Shimano uses for small parts and it doesn't show how the SIS unit comes apart - only that it is removable from the lever bracket. So unless someone draws a picture of the guts of the lever you're probably not going to find what your looking for.
    Sorry.
    I'd scan and post the diagram but my scanner has crapped out.

    The top prys off, there's a nut, unscrew the nut and stack the bits in an order that seems to make sense.

    Does Shimano even make 7 speed shifters anymore?

    Well if you know of some place that sells modern Deore DX or LX thumb shifters I am all ears. The only thumb shifters that Shimano sells are the no where near as nice Tourney.

    Alivio rapid fire units and Tourney thumb shifters. So, yes they do (to an extent).

    haha. Obviously you've never owned a set of deore thumb shifters. I'd take the deore thumbies over XTR rapidfire, much less Deore.

    Sure they do. Most of the Trek MTB's that are 7 speed use them.

    Actually I have. I also have no issues with the Deore rapidfires.

    closure here from the original poster if anyone is still interested: after many tries i managed to happen upon the right combination and got the shifter back together--so it can be done. thanks for all who posted responses.

    Yeah, they're pretty simple. That's why they're so great. I'm going to see if I can get an 8th click out of some deores I have for a new mtb build.
