I've come across STIs that felt a bit dodgy off the bike, but work quite well when connected and mounted.

I haven't encountered STIs that seem to work off the bike but don't on it.

Quang,

I have taken mine aprt and cleaned them, now I am putting them back together. I have a question on the pivot spring installation. I've installed the spring both ways. One way I get no spring tension, the other way I get spring tension when squeezing the brake. Which, if either, is correct?

There is only 1 correct way if installing the spring. One end of the spring has a 90 deg bend, which goes into a small hole above the pivot. The other end of the spring will point towards the front. When installing it, you will have tension when braking. Let go and the lever will spring back to where it starts.

I must be doing something wrong. The spring tension seems backwards. Right now the spring tension is keeping the brake applied and not springing back to the "riding" position. That is with the 90 degree end in the small hole, and the other end facing the handlebars. If I switch the springs from one lever to the other I get no tension.

It would seem that with the 90 degree end in the small hole, and the other end facing the front, there would have to be something there (in the front) to put pressure on the spring keeping the lever in "riding" position.

I got these shifters non working, so I don't know if the previous owner did something or lost a part.

I love the guides and the great images of the internals, I'm sure I'll be referring to them when I have to deal with extracting broken cable bits. BUT....

I see dried up STIs and Rapidfire shifters at least twice a week at work. About 90% of the time, they can be brought back without disassembly. We use alot of T9 lubricant, as it combines a solvent to break up the old grease as well as a fine teflon to re-lubricate. Spray in through the cable replacment port while working the shifter. As a last resort, I'll set the bike in the sun to let the grease heat up for a few hours.

A few randon thoughts and comments....

I've rebuilt a dozen or so 7400 and 6400 levers a few of which I've completely torn down to individual pieces!!!

1. General disassembly is basicly the same amongst them all. There are minor differences amongst them but this write up by QV will get the point accross
2. Ultrasonic cleaners work exceptionaly well. In fact, they work so well that disassembly isnt usualy needed.
3. I'll mount them on a dummy bar and use an inner wire to shift up and down through the gears....kind of like a test bed
4. After they're thooughly cleaned the entire lever mechanism can be submerged in the lubricant of your choice and left to sit over night. Remove and let the excess drain.

But really that's a temporary method. You spray in some new lube, which displaces the old grease temporarily. But it still remains within the mechanism, and sooner or later it'll start interfering with shifting. My method is simple and will allow for a better clean up. As well as the ability to remove frayed cables and the like.

And Jim, I have guides up for the 6400 and RX100(100% same as 1055) shifters as well. They are essentiall all the same. How are the 7400 shifters? ive never had the chance to work on them.

Also have a guide for the newer 5500. Will deal with a 5600 later on.

When you put the lever onto the body, make sure that the spring facing forward is resting on a flat section(just above the grub screw). Might sound confusion, but I'll take a pic later for you.

Quang,

I have installed the pivot spring like you said. With the 90 degree end in the small hole and the other end facing forward and there is no spring tension. There is nothing there for the spring to hit or fit into. Do you have any pictures? I will upload some pics tomorrow morning (about 14 hours) the bike is at work and I am home.

The spring should be like this. Now, you can have a look through my other threads, and I know that there are similar pics for the grub screw removal pics, but this is the clearest.

The left side spring will only fit the left lever, same with the right spring.

Talking about this?
http://www.bikeforums.net/showthread...ers?highlight=

Or, if youre talking about the first Ultegra branded brifter(6500 9 speed), then you want this. I know it says its the 105(5500) series, but it is exactly the same as the 6500 brifters, other than the different branding and colours.

thanks. That cleared it up. The straight side of the spring rests on the inside of the body. That's where it gets it's tension from. Makes sense. The guy I got it from obviously had taken these apart and didn't put them back together right. Thank you so much for your help.

There's not enough leverage for you to move it with your fingers. Just place that part into the lever body, and then place the lever blade in place. now have a go at shifting it.

If you've already put the shifter back together and it isn't moving, then check if you've seated the faceplate spring in the correct position.

I know this is an older thread but I just followed these instructions exactly on a pair of gummed up 105 shifters and they worked like a charm. The cable head was also stuck in the body of the shifter so this allowed me to extract the cable without any issues. There is one thing that I am unsure of now that the STI's are cleaned and reassembled. There is some sort of tension or spring that is opening the shifters now. Is this correct and if not what did I do wrong and how do I correct this? This is my first time working with STI's… The after picture shows how the shifters remain open under some kind of spring tension.

Disregard. I resolved this. I followed this instructional video and it showed me the problem. I do not have the Shimano STI Shifter Pin TL-ST03 so I cut a piece of cable housing then cut off the plastic casing. This worked just as well as the Shimano item. Great information QuangVong and thank you!!!

I'm glad you were able to do it. You must have a lot of patience. As I said in this thread two years ago, I have these shifters, and I was able to "service" them with only copious lubrication, but one day, I might need to do more.

Right now, the shifting has become slow and sometimes unresponsive. I don't know if the problem is in the shifter. I suspect the derailleur is getting sloppy. I think these components were not made to last all that long. And given that they are 20 years old, I shouldn't complain.

Thanks Tom. These shifters seem to be really sound now that they are cleaned up and reassembled. I took them off of a bike that I picked up just to part out. The owner retired and has no interest but the bike and the components are great. What bike do you use these on? I am undecided on which one I should use them on as of yet.

P.S. I will be heading down the West Side Path Wednesday.

Sorry to revive an old thread but I am attempting to repair the left shifter and after removing the 2mm and 5mm allen screws the name plate does not want to come off. Any tips or suggestions of what im doing wrong?
