    Ultegra bar-end lost some indexed clicks?

    Last week while riding home, I noticed my 8 speed ultegra bar end shifter wasn't "clicking" as it should. I noticed that the flat head screw which held it together was loose, so I tightened as best I could with the flat head on my multi-tool and got home.

    Once home I disabled, greased the screw and tightened things up properly. Yesterday I noticed that some of the index points aren't working. The lever physically moves the rear derailleur, but over certain cogs it's strictly friction.

    Things basically function, I can use the entire range of my cassette, and am not above using friction mode since this is my commuting bike.

    What could be causing this?

    These shifters have a ring on the right side lever that says "SIS" or Frict". The SIS is the indexing mode and Frict is, umm, friction. If the D-ring isn't turned completely toward the SIS indicator you will have either friction shifting or erratic indexing.

    "erratic indexing" is a much more concise description of my problem. I will check out that the D-ring is positioned all the way to SIS.

    Thanks.

    Did you disassemble? If so, it sounds like you reassembled incorrectly and rotated the lever 90-degrees from where it should have been. I did the same thing the first time I serviced my bar-ends. I had indexing on the small cogs and friction for the large cogs.

    I've had this happen when the mounting screw is just a little loose. I'd go back and tighten it down with a big screwdriver- there's no way to get enough torque with a little multi-tool thingy. Find the biggest screwdriver that will fit in the slot and go to town. I've done this since I started using Shimano bar-end shifters (1991) and I've never damaged a screw by overtightening.

    Yeah, it may need to be disassembled to make sure the dark colored washer is positioned correctly. I've had this happen. There's a little notch on the washer that has to line up with a protrusion on the silver ring, or something like that. I can't remember exactly, but when you see it, it's fairly obvious. If it's out of position, the shifting is way off.

    Take a look here:

    The fat tab on the locating washer (part #2) needs to be pointing down when the shifter is mounted normally. It can be mounted 4 different ways, so it's easy to screw up. Once you learn the proper orientation you'll never forget.

    It's strange, because the dark colored washer I referred to isn't shown in the diagram. It's orientation is the same as part number 2. It goes between part 2 and the shift lever itself, which isn't numbered in the diagram. But with the diagram, it does remind me how it all goes together, thanks-
