    Is there a hi-vis version of WD40?

    Not sure if this has been mentioned before, but you were measuring (rubber) with precision measuring instruments?














    Really?




    OK, OK - if thats ok-

    You put these solvents in a plastic container that youre sure didnt degrade when you added them AND the o-rings into?


    I know Im a few years behind on this.. but really? What kind of scientist are you?

    I have been using Starter Fluid Spray (diethyl ether) from walmart.

    The can is $2, and I can get my chain very clean with just 1/3 a can.

    Some tell me it's not oring safe, but it's not in contact very long and works so great..just blasts the dirt off and dries quick.

    DO NOT USE AROUND FIRE or KABOOM

    Do you ask for an MSDS before accepting your Quarter Pounder?

    Oh,,, that was just fer quick reference as he had all the data from the measurements taken on the MicroView stored on an ExcelDoc. at the time.:1drink

    It's a viloation of Harris County Law to use starter fluid like that. It's OK in Waller though.

    I just use a stiff brissle brush to knock the crud off then relube with some type of silicone lube.

    Great report. Ive been using wd40 for a long time in my bike's o ring chain and no problem. Then I blow air before adding Motul Offroad chain lube...

    I've found WD-40 to be a great grunge cleaner for any grimy parts of an engine, chain, or frame. It's not a lubricant, but it seems compatibility with o-rings is more important than lubrication. However, I'm using an automatic chain oiler with 2-stroke engine oil for the chain. The oil is about the same viscosity as ATF and should provide some level of lubrication, since it's an engine oil. But, back on topic, a gallon of WD40 and the the spray bottle can be bought at Lowes, Home Depot, etc and is much more economical and easy to apply than the aerosol spray can.

    Exposure PLUS heat and friction would have been a very interesting over-time test, but... you'd need a lot of exact bikes being ridden identically - or a machine to keep the chains in constant motion.

    Great for cleaning. I continue to laugh at those who think it's a lubricant no matter how often you can read a plethora of things that flat out say otherwise.

    I use WD after cleaning the chain with a water based degreaser, S100, Simple Green, etc.. It takes care of the water after rinsing and prevents rust until the chain is dry and ready for proper lubing. WD=Water Displacement.

    I have been using RP7 for many years cleaning my chains with it with a rag. Chains looks fine even after 50k km. I also use scottoiler with dual injector to oil my chains.:D

    Meant to be light-hearted here, but I would laugh at you if you sprayed your MC brake rotors with WD 40 and then tried to stop your motorcycle before hitting whatever object you were trying to avoid.

    Of course WD 40 has some lubricating properties. It may not be up to your defining standards, but try my little empirical experiment and report back.

    Back in the day before o-ring and x-ring chains (over 50yrs ago) when you would buy a pan of chain grease and boil your chain in, it an old mechanic told me that he would first boil his chain in water!!!!

    Only then, after the water cooled would he boil the chain in the pan of grease.

    The logic was that the water would get into the chain rollers and because the grease had a higher boiling point than water the water would evaporate off causing a vacuum that would then suck in the molten grease.

    Demon logic eh?

    Just seen how old this thread is! Just a bit of old fashioned wisdom.

    I do not know if it was mentioned before,but polymers degrade and fail faster
    under the so-called "environmental stress cracking".
    It would be very interesting to see the results of the same experiment while the o-rings are under stress(squeezed or tension),
    simulating approximately their working condition.

    Thanks for that post, Antonio
    "You can lead a horse to water, but you can't make some of 'em drink it."

    In other words; some still think of it as a lubricant.
