Sheldon recommends not servicing freewheels but the one on the new bike is very dirty indeed on the sprockets. I wasn't planning on completely stripping it though. Seeing as the wheel needs respoking anyway (the guy I got it off had ridden it with a broken spoke until a second broke) I'm tempted to remove the freewheel and throw it in the ultrasonic cleaner at work for a while then relubricate it. Has anyone else done this? Is it a stupid idea? Should I just manually clean it?

is it a freewheel or a cassette. If the latter an ultasonic cleaner will be OK. If its the former then make sure you can get lube into the internals after you ahve removed all of the old stuff.

Definitely a freewheel. There still seem to be a number of 7 speed freewheels available in case I screw it up ;o)

I'd just clean the outside (sprocket area), using some degreaser (or white spirit) and a narrow brush (cut down an old toothbrush if you lack the "official" part. Then, when clean and dry, put it back on the bike. I do this now and again with the screw-on freewheel blocks on two of my bikes.
I have taken a screw-on freewheel to pieces before, there isn't much inside them to worry anyone. Requred a punch & hammer on the two little indentations on the front of the freewheel body, and I have a feeling it might be a LH thread.

If this is an ultrasonic cleaner used for cleaning PCBs or other electronics, then make sure your employers are happy for you to do this! I know I wouldn't let anyone do this where I work!

If it doesn't feel graunchy I'd just floss the sprockets using a rag. NB I have a (used but not used up) 6 speed Shimano SIS 14-32 freewheel if anyone wants it.

Yep, one of those. It's barely bigger than a freewheel but it is quite deep.

Trust me, it'll be fine ;o) It worked a treat when I threw the head from the PCB milling machine in there, I just emptied the solvent, wiped out the residue and refilled it.

Ah - one of the little jobbies!

Solvent?? You're not allowed to use that any more - you'll have the enviro-euro-police after you :-) You will at least get it clean though!!!

Lubing a FW is easy even if it doesn't have ports for getting the oil in. Just let some medium-light oil (not sunflower!) run into it until the sound it makes when you spin it changes.

It's not difficult to do it by hand - just scrape out the worst of the crud with a screwdriver, then attack it with a stiff brush, finally a squirt of WD40 and a wipe with a rag. It's easier to do it on the wheel rather than remove it.

I dunno what the stuff in it is. It had a particular name and wasn't just deionized water, probably just water with a bit of IPA in it.
Someone has nicked the bath to do some proper work with it so I'll have to do it the slow, boring way ;o)

Isn't IPA just proper beer with water in anyway ?
I overheard a bloke trying to be knowledgable in a pub.
His girlfriend asked what IPA stood for. He told her India Pale Ale. So far so good. He then rather spoilt it by adding the "fact" that they brew it in India and ship it to the UK.
