The Myth of WD40 penetrating O rings and ruining chains was long ago de-bunked by actual Lab work. Even some of the magazines did this test, MCN for one.
Chains soaked in WD40 showed NO penetration into bearing area and NO dilution of internal lube. (typically Lithium grease)
Additionally, O rings soaked in WD40 for two weeks proved to be as flexible and as strong as new, unsoaked ones. NEXT!![]()
Hmm the only attempt at investing WD40 is this: https://www.motorcyclistonline.com/mc-garage-video-will-wd-40-destroy-your-motorcycle-chain-o-rings
I guess that’s what you meant about O rings being soaked in WD40 being fine? This doesn’t prove anything - the O rings could be perfectly fine, but if WD40 seeps past the O rings and hits the grease inside, it will dissolve it and shorten the life of your chain. If you have a link to an article that investigates what happens when you soak a whole chain in WD40 I’d love to see it.
