Vitntage Parts

I have a 1984 14 speed Fugi I purchased new and am looking for a front derailer since mine has froze up. Is there anything I can do to unfreeze it since I can't seem to find parts anywhere. Or if you know where I can get parts for it that would be great.

If it's rusty try soaking it in white vinegar for a while; if it's grimy soak in a solvent (ie mineral spirits or kerosene) then spray with WD-40 and work the linkage open and closed; after it frees up, lube the linkage with Triflow or some other lubricant.

If the der is a SunTour then there's a likeihood that you can pull apart some of the parallelagram. Many of that vintage ST units would come apart at two pivots if the spring was detatched first, sometimes there was an "E" clip too. Most ft ders will respond to "working" them loose with mechanical action and solvent flushing. Andy.

you should be able to find a replacement derailleur, I assume that it is a clamp-on type. You can find many different clamp on types or you can the clamp for the braze-on type.

Start by removing the derailleur, and soaking it in petroleum solvent for up to 24 hours. Then try to work it in your hands and see of you can get any movement. Then take it apart, clean, lube and reassemble it.

If all else fails make a note of the brand and model (see rear derailleur logo) and do an ebay search.

If none of the above works, a suitable replacement can be gotten for about $15:

Since the bike is not all original parts, unless you plan on restoring it to its original state, you can just throw any old front derailleur that fits (bottom pull and the correct diameter clamp). New road derailleurs are made that will work (starting at about $15-20), as will just about any older derailleur. Pull an old 10-speed out of a dumpster and it will have a derailleur that will work.

Had a similar situation last spring. Took some clear plastic wrap... wrapped the 'railer snugly to trap the PB Blaster I shot into it liberally. Sat a few days... it came free.. flushed it with more Blaster.. and off to the races.

Parts for a 1984 Fuji are readily available. There are hundreds of vintage front derailleurs available on ebay, for well less than $20 (there are several decent Suntour ones on ebay for $10 or less shipped, BIN). You don't need new, you just need one that is working well and preferably rust free. There are probably some for sale over on the vintage forum as well.

I have found that the old Suntour parts are quite durable. Unless they are badly rusted, they can last just about forever. I am routinely mounting 30+ year old Suntour parts onto bikes.
