I'm in the process of overhauling my Campy Croce d' Aune rear derailler. It's dissassembled as far as it can be except the linkage pin is still connected to the main body (the c clip is very small and I didn't want to risk breaking or losing it). I am able to clean (with soap and a toothbrush) all the parts very well except for inside the main body where the springs are (too small to get toothbrush in there). I can see grease and crud in there and was wondering if boiling in water would work (note it is very smooth so its not a big deal, I just want it to look clean in there). I wish I had an ultrasonic cleaner but I don't. I'm guessing there are bike specific cleaners that I could spray in there too. But....will a simple boil in water work? Or will the grease just stay there. Will this harm anything(I don't think so)? thanks!

Ahh good ol Italian cooking!

Bring water to boil add a touch of salt and olive oil and cook for eight minutes. Season to taste with some good ..... wait a minute!

Seriously, I would get some "Purple Stuff" and spray it let it sit for a couple of minutes then run it under some hot water. Then blow it off with compressed air. Make sure you lube it up with your preferred oils and what not as it will be as dry as a bone in there.

Put down that double boiler

How about you just sluice it with solvent? The grease is not water soluble, and if there are any plastic parts anywhere, boiling water will not be good. It could also be hard on the lettering. If you just dunk it in odorless mineral spirits (or something like that) you should be able to get it whistle clean. Just don't forget to re-lube all the pivot points with oil, which will keep things working smoothly. The oil will, of course, attract that dirt and get you right back to where you are now, but that's the price you pay.

Don't forget to throw it against the wall to see if it's cooked enough.

When Speed_Metal said, "I use a technique that is quite easy, and can be done on the fly, but it involves a highly toxic and flamable gaseous substance that has acutally been banned in 37 states. It is also frequently accompanied by a concussive blast so loud and forceful that has been known to cause temporary ear damage and on a few accounts, organ failure. So I really can't recommend this method", was he referring to his farts?

You can get giant bottles of Simple Green for 8 bucks. I place the part in a Tupperware container with a Simple Green diluted solution. Clamp the lid, and shake back and forth 20x or so. Then you open a beer. Repeat.

Then shake the solution again.

You can save the solution in a big bottle and reuse it.

for what it's worth here's what the Ruth Goldbergesque Croce d' Aune rear derailler looks like taken apart. I did not remove the small c clip where the linkage pin connects to the derailler body (didn't want to break/lose it). Other is a Mavic 851...

My things that suck list.

1.) Trying to put a Campy derailuer back together....

There that is now at the top of my list. Looks like you have 3 different size springs (of the 4 pictured), Do you remember which goes where?

those little springs just go on the travel limit stop screws, the screw that screws against the dropout hanger and I forget the other one right now but it will be obvious. It's really quite straightforward (I...uh...think knock on wood), the bigest problem (as with all rear deraillers I think) will be getting the pulley cage to connect to the body and have the correct amount of spring tension. But there are only two spring holes to choose from on the campy, on the mavic there were like 12 or more.

ps- I am quite glad I posted this stupid ?, otherwise who knows how long it would have been before I learned how to shape my SLR saddle to me rump LMAO!!!!

I would have to agree that if you can't remember how something came apart, and don't take steps to reinforce that memory (simple things like laying the parts down in the order they came off), then reassembling a Campy derailleur is beyond you. SOME people, however, find it no problem :)

Carburetor cleaner

I used to own a Croce' equipped bike and I know difficulty in getting it clean. I used carburetor cleaner with not ill effects on the parts or finish.

what what what?

heh... pls dont get anything from the bike shop !!

why do ppl recommend simple green and other citrus based degreasers? I HATE THEM.

(pls excuse me if im thinking of something else), but those bottled degreasers rely on either a strong acid or base to clean the item. Look at the warning label, it also eats metal !!

what a way to ruin beautiful campy !! i tried some of this stuff on my wipperman chain, and it quickly killed the gold color on it... i would shudder to think what it might do to the campy lettering.

i use.. wait for it... kerosene.... its cheap, its availiable almost everywhere, and it doesn't damage anything unless you decide to take up smoking right then and there. I love the stuff, it works great, no side-effects.

it would be perfect for this problem, throw the part into a plastic bottle or even glass jar with lid, pour some kero, close the lid and shake... drain, and repeat as necessary.. simple ppl !

Hmmmm. I think you are indeed thinking of something else. Citrus cleaners are basically limolene, which is a pretty innocuous oil. It is most easily thought of as "orange peel oil." My bottle of Pedros has no warning whatsovever about use with metals. That said, I find that odorless mineral spirits works great, and smells a lot less than kerosene or similar.
