Ultegra shifter repair

Quoted post said:

Any ideas? pointers? etc.

This won't help now, but in the future you might want to take some
closeup digital photos before disassembling something that complex.

Congrats on at least finding the problem. You're braver than most!

The right shifter on my bike has been sticking all winter (when I move
the small lever it moves the big lever with it). I think it must have
gotten gunked up and needs a good lube and clean. I was talking to one
of the guys I ride with and he pretty much told me STI shifters are
not repairable, called a LBS and got the same answer. I figured since
the shifter is not working and I will have to replace it why not make
an attempt at repair. So I took it apart, I mean the whole shabang. I
found the problem, hardened grease and one small piece of metal
(broken off a washer-does not impact the working of the washer) which
had embedded itself between two levers. Anyway I cleaned up
everything, and yes I admit it I can't put it back together. I think I
have everything installed correctly except the operation of a small
release lever which clicks the gears one at a time for up shifting.

I checked the shimano website and they do not have any exploded views
of the innards, searching on the Internet hasn't revealed anything
yet.

Any ideas? pointers? etc.

Much appreciated.

P.S. I wish I had seen this news group before I took things apart, the
WD-40 flush and lube may have solved my problem.

Somebody on this newsgroup posted pictures of an sti assembly.
I downloaded the pictures. but it's a total of 11mb.
I could try and mail them to you

When you consider the value of your time, you'd have come out well
ahead to have taken the points from others and just replaced the thing
as recommended.

All good advice. I like tinkering with stuff so the first instinct is
always "I can do it myself". I think I will eventually figure it out
but I hate to be off the bike for the week (or 2) it seems will take.
I just work at it during night while watching the Australian open
tennis.
I'd have taken close up pictures but my point and shoot digital is not
good with closeups. As they say hind sight is 20/20, I could have
tagged the various rings and springs to mark the order in which they
came out.

WD40, nor any other "lube" I've tried, has come close to being as effective
as PowerLube, available at finer auto-parts stores everywhere. The stuff is
tremendous, and doesn't seem to have problem with colder climates.

On another thread, a poster suggested using aerosol chain lube instead
of WD-40. That worked better for me on an old Ultegra shifter that was
sticking on one of my old bikes.

Bill Cotton's STI repair:
http://www.billcotton.com/sti_shifter_repair.htm

Further, besides not having any diagrams or repair manuals available
on repairing STI levers, there is also the problems of not having any
small parts available. In contrast, Campy has all of its small parts
available for its Ergo levers and there is a factory repair manual.
Moreover, if you go to Youtube, there are complete videos on both
assemblying and disassemblying an Ergo lever.

Thanks Bill, I had read your article earlier in my quest. Here are the
links that do not work.

Just a clarification, WD-40 is not considered a lube it is more of a
cleaner/water remover/solvent. One should use some kind of oil
(PowerLube seems quite popular) after it.

Officially they are 'non serviceable' and few LBS are confident of
ending with a functional lever and getting paid at their usual rate for
screwing around inside there when unavailable small parts are needed.

That being said, search archives of this group for Bill Cotton's
experiences on the subject with links. I defer to him as the expert,
Lord & Master of STi Rebuilds.

Hey zrnaqvi....I too was unable to get any help from the Shimano
website,
but I found this by accident the other day, seems to be part of the
Shimano
site but I don't know how to get there with their navigation, I found
it through
a Google search.
Lots of info including exploded views for Ultegra 6510, 6600, 6603,
R600, & R700.
Scroll down to the heading: "ST Dual Control Levers", lots of pdf's
with nice drawings,
explodeds, and even instructions for how to operate the various
levers.
Sorry for this horrendous url, someday I'll learn that tinyurl thing,
after I learn how to fix an STI. :-)

thanks ABS, I have already looked at these PDFs, unfortunately my
problem is deeper. These PDFs do not go into the inner details of the
actual shifting mechanism.

Do not use WD-40. It soon turns to glue.
Use a true penetrating lubricant to clean and lubricate brifters.

Those pictures are awesome. Unfortunately I now know why I couldn't
get it to work. In the first picture (with all parts laid out), the
fourth washer (from left top row) is broken on mine. The small tab
that holds the spring in place for the small lever is broken, that is
what was interfering with the down shifting. I am also missing the
spring, 7th item from left in second picture. Thanks again for the
pictures, these are worth a few thousand words.

Again, these pictures aren't mine, a pity it didn't help you to fix the
shifters.
But I'm glad they shed some light on the problem.
