shimano 600 sti shifters

I bought a Raleigh Technium 753 with Shimano sti shifters. The rear derailer is not shifting. The shifter seems like it is sticking internally. Are these rebuildable/cleanable. It would be great to be able to keep them instead of replacing them with something else. Thanks for any help.

Solvent bath, soak overnight or ultrasound.

Failing that, overhaul is possible if your skillset extends halfway to watchmaker.

WD-40 flush. Empty like half a can in there at everything that moves. You're trying to dislodge little chunks of crud... usually works. Don't do it in the living room, there'll be lots of runoff and drips.

If flushing fails,
there's a guy on ebay that sells Shimano 8s rebuilding services.

Edit: he's now also on Facebook

Actually, you're tying to dissolve the stiffened grease in the pawl pivots.

I've used the guy on facebook to rebuild at least six pairs of STI.

That's what I did, pumped the shimano 600 brifters full of solvent, worked the levers a bunch and let it soak for a bit, then relubed with a can of TriFlow. Shifters went from "broken" to awesome in one night.
