    SRAM 3.0 RD fixable?

    I'm rehabbing a bike with an SRAM 3.0 RD. This is my first time working with SRAM rear deraillers, and I had assumed that like Shimano RDs, you could remove the jockey wheels for cleaning and relubing. On this RD, that doesn't seem to be possible (am I wrong?).

    The jockey wheels were pretty gummed/crusted up, so I've wiped off what I could, used plenty of WD40 flushing to loosen/remove crud (don't worry, NOT for lubing), and even soaked the bottom wheel end in warm water + dishwashing liquid O/N. The upper wheel is fine now, but the bottom one still feels like it has a little piece of grit in it when I turn it. Any suggestions on how to get that out? At this point, I'm tempted just to give up and spray silicone lube into/onto each wheel and be done with it.

    soak it in parts wash for a few hours if the 3.0 has a metal casing. I think the stuff we use here at the shop would be too harsh on cheap plastic casings, personally. Park Tools makes a brush designed for getting grit out of springs, etc. that would work.

    My father-in-law told me once that charcoal lighter fluid has the same chemicals as parts wash (naphtha SP?) and the only real issue is keeping an open flame away. Of course, he told me that this is the same chemical they use in dry cleaning, so /shrug. Coincidentally, he manages a chemical refinery that bottles and ships the crap - so he's probably not totally off the mark.

    Bottom line, I soak parts for up to 24 hours depending on how abused (and neglected) a part is in the shop when I do complete overhauls. Seems like the solution I'd go with.

    S - I agree, that would work for Shimano RDs, but this SRAM 3.0 is plastic, and seems to have the jockey wheels riveted on (unless I'm mistaken!), so I can't actually get at the axle/bushing to remove the grit.
