Reassembling ST-7700c lever - help

Does anyone know how to do this? I have assembled right lever because cable
that gives information to Flight Deck was broken. I repaired this but now
when I reassemble lever it does not function OK. When I shift it bigger
chainring (lower gear) it does not come back and I have to do this manually.



On Shimano pages there is explanation only for partial assembling.

Maybe assembling lever wasn't such smart idea!

Not a good idea. shimano Europe has a better blowup for this but I
would try warranty. i have sent 7700 levers back in zip lock bags, as a
bag o' pieces and they have warrantied them.

Just sent back the 5th 7800 lever, BTW-

Go to: http://www.cyclingforum.com/features/findex.htm

and click on: "CyclingForum Tech Tips"

then click on: "STI Disassembly/Assembly (105/8spd)"

This will cause a Word .doc file to download. While it's supposedly
specific to the 105, 8-speed levers; the description of how to get the
spring installed and properly preloaded (probably your problem) is
most likely generic enough.

Yow, not good. You don't say how old your levers are, but I would agree
with Peter that you should definitely try to get your lever warrantied.
Remember with Dura Ace you have a 3 year warranty, not 2 like the rest
of Shimano products.

If you can't warranty your levers, here are a couple of sites that
might help:

Steve Alkire's 105/8spd disassembly/assembly

Otherwise, good luck with all that!
