Me and Murphey

T95 · Jan 7, 2011

I purchased a bottle of Marvel Mystery oil yesterday. The plan was to pull the plugs and soak the cylinders.

As I have mentioned before my bike has been sitting for thirty plus years. Still entombed, I cleared the debris from the top and straighten her up. The first plug was hesitant but I freed it up and got it out. The second one fought me all the way. I broke off the insulator due to a bad angle on my wrench, how does it go, Hast Lays Waste! I finally pulled the tank and seat to ensure a better angle. I used every approach at my disposal to free the plug, but Murphey's law was leading the charge. Three hours later the cylinders are holding about four oz MMO each.

If this is any indication of what in store, this restoration is going to be a journey!

I am working on a bike that sat for 34-35 years. I flooded the entire engine, gearbox and primary with ATF and acetone and let it sit for over two months. While this may have been overkill, it seemed like it couldn't hurt either. The only negative impact I have found to date is that my stator looked like a piece of moldy cheese when I took the primary apart as the acetone apparently didn't get along with the resin very well.

The Marvel is a good idea. Be patient!

Don't feel too bad. Dad and I spent probably three hours trying to strip the rims bare. Knocking out the front bearings took about two and a half hours. Everything else took a combined 30 minutes or so.

Someone here mentioned brake fluid and acetone a while ago too. It might be a good idea to remove the stator and rotor before soaking everything. They shouldn't be too hard to get off but you never know. Then there's the swingarm spindle.

At least I am in the pre-soak phase for the cylinders. Every bolt on her is going to need penetrating oil as well. I plan on moving her to another location before dissemble. I don't have the room I need here. After today I want to make sure I have ample room to move around her to wrench. It will also give me the room to organize and store everything.

Use Marvel Mystery Oil for your de-siezing. It is known for it's ability to do that and it won't damage other parts. Great stuff. Unlike most such products it is NOT snake oil. For many years it carried a Milspec number and was used my the military in 55 gallon drums.

actually ATF and acetone is ( 1:1)
- but marvelous mystery oil and acetone are great too

*Penetrating oil ..... Average load*

None ..................... 516 pounds
WD-40 .................. 238 pounds
PB Blaster ............. 214 pounds
Liquid Wrench ..... 127 pounds
Kano Kroil ............ 106 pounds
ATF-Acetone mix....53 pounds

Well the MMO is cheep enough, about 4.25 a quart. All the other alternatives are also cheep, but now I only have one small bottle to store. Besides it comes in a nice candy red container and it also smells pretty good.

"actually ATF and acetone is ( 1:1)"

Ok, so my long term memory is going too.

I can never get these quotes to work right.

Corroded in spark plugs is bad omen for similar strain of will power and manhood till the very end. MMO is not as good or cheap as AFT/accetone/brake fluid. Also remember about heating and melting in candle wax. Impact air tool can save ya swearing on shearing off flats. Hi heat source a few times with penatrant and some whacks and test tugs over some time can win the day. Wait till ya try to get the head off, or the spindle out. Group mental focus can work magic over night I've found a bunch of times after crying out loud on lists. Oh yeah if disc brake then the caliper plug may get a nasty name by you, then the insides get ya...

Sorry but I need some help interpreting these ratios:

Are you suggesting to use the ATF and Acetone in a 1:1 mix?

Is the lower figures stating that if it takes 516 pounds to lets say loosen a bolt without penetrating oil, then if you use say the ATF-Acetone mix it would only require 53 pounds?

Don't go sending any bad VooDo my way! ( Good Omen, Good Omen)

The MMO was convenient to say the least. I'll file the heating and candle wax technique. My bread and butter technique is always to hit my breaker bar with a couple good blows to break things free. Worked on the first side. My impatience and bad angle attempt had me working on the second side for another hour. I reluctantly used my impact wrench and it did the trick. I was worried I was pulling the threads out, but it was ok.

yes and yes ;

1 part acetone to 1 part ATF (or MMO)

and yes all things being equal about 1/10 effort compared to untreated bolt

i have also found that diesel fuel works very well too (I have used successfully to free up stuck pistons cylinders) but never directly compared it to my fav acetone/ATF combo

Unless you clinically prepared a 6-bolt/lug array with meticulously pre-corroded contact before performing the experiment, how can you know these things?

Also, a resistive load of 500 pounds on a frozen fastener would surely snap the shank or destroy the tool being used before yeilding, I would think...

Don't go gettin' all scientific-like on us! Some things should just be accepted as real, like Santa and breasts, it is better to just believe!

mikegray660 · Jan 8, 2011

if its written on the web it has to be true right?

similar to many of the post on this forum for example! :mrgreen:

AntrimMan · Jan 8, 2011

MMO has it's place. As a last resort It worked for me on automotive hyd tappets.
Ethyl ester aka brake fluid is good too at loosening frozen bores but murder on uncompatible rubber over time.
...as far as Santa and breasts, if I read that correctly, it should be separated.
...Santa, signs all my Christmas gifts. I believe, and it appears Santa is a she.
...breasts, anyone with them on the back is fun to dance with. ie Millie with the three humps, if you're from around here.
oh, my goodness, you've got breasts. I like those on a woman.
Maybe I didn't read read that correctly after all.
Snow sucks, think warm eh?
