    Anyone have any experience with disassembly, cleanup of older 8 spd Ultegra STI levers? Source for exploded drawing, ect? Have an older set I would like to rehabilitate.

    I've had Dura-Ace 8-sp shifters apart when I had the outer housing powder coated. It took me a week to get them back together again.

    I started to do it but quickly gave up and reassembled them and sold them on ebay and consider myself lucky to be rid of them-the Shimano site has some dissassembly/ assembly instructions though if you are braver than me-good luck-I think some special tools may be needed

    Thanks F1,

    Was looking at an exploded view of the current 105 shifter on Shimano's site. It looks fairly simple to remove the "Front Cover" the chrome piece on the front, 8mm hex. And the Main Lever Assy. by removing the "Lock Nut" (some kind of spanner) on the back. These have shifted pretty good in the past, just looking to disassemble so I can give the Lever Assy. a better cleaning (ultrasonic). They are a bit gummed up from sitting around for 8 years.

    My understanding and I could be wrong is that you can't rebuild the internals on these shifters. That wouldn't surprise me given Shimano's business model. However, I have seen on Ebay from time to time "guts" for STI shifters. Apparently you remove the innards and stick in some new guts. I guess that beats throwing away the whole shifter. Again.... please correct me if I'm wrong this is just what I've noticed.

    Again I don't really care to rebuild the internals. Just want to remove the "Front Cover" and pull the "Lever Assy", which contains the internals, so that I can do a decent cleanup. Wondered if there were any mechanics on this site with experience in this area.

    I have done it- you are supposed to have special tool to put the lever return spring back in as the placement is fairly crucial but I managed without it (I think).

    Yeah, I've done it. Helps to have instructions or diagram to get it back together right.

    Yea, I had to laugh when I finally reviewed the drawing. Shimano "Return Spring Installation Tool" TL-ST02, looks exactly like a Spring Pin ($0.20 at the Hdwr Store), they prolly sell it for $20 or so. LOL

    yes a little tube would probably do it-like the one you get with WD40 cans
