Diagram of Shimano 105 shifter internals?
Sean Smith
to search at all with this service....
Anyway, I'm looking for a diagram of a Shimano 105
shifter's internals so I can fix mine.
Thanks.

I've seen this reference before in this newsgroup and have gone to the site
and rooted around. But I've never found the files. Can you be more specific
about where they are located, or how to track them down?

it's a non servicable part according to shimano, so it is unlikely that
a detailed drawing exists. The most detailed drawings will be Dura -Ace
but apart from the tools to take them apart Shimano will not provide any
spares apart from complete assemblies at huge cost.
If it is 9-speed with flitedesk, (with the levers moving together
syndrome) try to get a replacement under guarantee first before taking
things apart and voiding the guarantee

Unfortunately, when I needed to fix my 105 shifter, I could not find a diagram
with the level of detail I required. The best I could find was the links above.
While it is possible to take the lever completely apart then put it back
together in a functional state, I would never do it again.
The first problem is that there are so many pieces that it can be difficult to
remember how exactly they go without being very careful. The second problem is,
when you take certain disassemble certain parts, springs that were loaded,
unload. When you go to put the parts back together it is very difficult to load
the springs then put the parts back together. When taking apart the 105 lever
the most difficult part to re-assemble is the cap that covers the internal
mechanism. There is a spring that unloads as soon as you take the piece off,
getting that piece back into place is no fun at all.
When I took my lever apart I found a part that held the one of the many springs
place was broken. So, what could I do? nothing, because it is not like you would
be able to buy these parts anywhere.
So, there is no point in taking the lever apart, unless you have a second broken
lever that you can take parts from. Even then, the level of difficultly in
reassembling the lever without specialized tools is so great, that I would
highly recommend against it.

1.) Click on catalogue
2.) Click on Mountain Biking or Road Racing or Comfort Biking (depending on
what area your group falls into, DeOre, XT in Mountain, Dura Ace, Ultegra, 105
in Road, Nexave in Comfort)
3.) Click on your group (example 105)
4.) Use the arrows to scrow down to your part (example Dual Control Lever)
5.) Click on the model (example ST-5500)
6.) Click on your chose of Exploded view or the Service Instruction to download
the PDF files.
Maybe they should import this to the US site with a more direct way of finding
this info?
If you want to see the newest stuff from Shimano, this is the site. They had
the Dura Ace triple on their site before anyone else.

It is true that there are quite a lot of parts in an STI mechanism. I
counted 30 in my 8 speed RSX rh lever. And it is probably out of the
realms of a someone without reasonable patience and mechanical/technical
skills to service or repair one. Just the same it is possible and once you
understand how they work, it isn't all that daunting. I got great joy from
dissassembling mine and changing the shape of the cam to achieve a
smoother shift. I also got to lubricate everything thoroughly with grease
rather than light oil. I'm no hero, but I did all this without any special
tools. I did, however, have to grind the ends of a pair of circlip plyers
(buggered anyway) to undo the castellated nut which holds the whole show
together.
As a last resort it may be worth pulling your STI apart. I had no choice
because I couldn't live with mine the way it was and I had no money to buy
anything else.
Hope this helps.
Cheerz,

Easier on a Flite Deck lever if you leave the Flite Deck bit out...

The one I took apart had worn such that one part would ride up a second
part
rather than turning the second part. I tried filing off the burr it had
created, but it didn't help. Dead lever.
...which is why I've switched to Campy... A Daytona 10 spd Ergo lever
will
shift a Shimano 9 spd 105 rear derailleur with a slight cable reroute,
was
cheaper for a pair of levers than 105s, and I prefer the adjustability
of the front shifter too. Anyone want a front 105 shifter?

A huge thanks.
I've fixed my STI's in the past, without any diagrams,
but it was a real forensic task, the details of which
I've forgotten by now. I'd even had to manufacture a
silly little spring which I found to be the cause of my
problem. This was all about 2 years ago.
I would probably have capitulated if I ever had to do it
again without the diagrams.
