I've seen bunches of references to this magic juice, almost universally positive, so this may be old news here. I've always had decent success with PB Blaster so never got around to trying it.
Until now.
Working on a well-used Honda TRX400 4 wheeler. Rear axle, sprocket, bearings, and hubs worn slap out.
It's a solid axle, bearing carrier is an aluminum eccentric mounted in an aluminum swingarm housing. To adjust the chain tension, you loosen 4 mild steel pinch bolts in the aluminum swingarm and rotate the eccentric.
3 came out with a reasonable amount of fussing and a little PB Blaster.
4th wasn't having any. Couple of days of Blaster, heat, percussion, vibrating it with my battery impact and copious amounts of verbal lubrication...all to no avail. Absolutely zero perceptible progress.
Mixed up a 50/50 batch of ATF and acetone, shook it up good and douched the fastener and general vicinity liberally. Repeated about 4 hours later. About 2 hours after that, tried it with an allen wrench and it turned quite easily. Hit it with the baddry impact and it spun right out.
Given the speed with which acetone evaporates, I don't think I'll try to keep a batch on hand, but I'll certainly keep the ingredients handy and mix up a small batch when called for.
