how to undo loctite
saw the question on yellow…i dont like that forum so heres the answer
1 heat !
screws loctited in place, i use heat from candle and put torque on the screw while heating so i know the second that it’s letting go, so i avoid to overheat, works great on tophats loctitet to stems…its actually so easy to pop the stem, heat it just enough to twist tophat, remove from heat source and the glue will set…no more wandering tophat, no setscrew marks on stem
bake the item
ldc glued to barrel, valvebody in tank etc….be very careful with heat ! heat might unleash some stresses with in the barrel/bottle…dont want that, instead you can boil the part if in a hurry….
2 acetone
acetone will do the trick, in radio controlled cars i often dunk mounted tires (tires “superglued” to the rims) let them soak for 3-4 hours and the glue turns into slime allowing rubber to be removed from the plastic rims, without tearing one or the other out of shape, from previous experience a theoben ldc will come off with this method as well, with no stress to parts
beware, some plastics will dissolve in acetone, acetone is great at stripping paint, great degreaser etc…you have been warned LOL
3 shock….valvebody in bottle…put a long screw into the dumpvalve hole (after removing setscrew and brass washer) hold bottle firmly and put a hammer to the screw…

Yes, yes and yes…. 😐
I think that I would have to agree and alternate acetone and localized heat. Caution acetone is hella flammable.
The biggest hurdle or trick is getting the heat localized and into the sticky parts.
On set screws and such I use a medium to high wattage soldering iron tip right on the screw head. On larger screws or bolts I use a very fine tipped butane pencil type torch. I use the very thin blue jet of flame right on the bolt or screw head.
Remember heat and acetone will melt rubber seals , plastic and other synthetic parts as well as finishes too. You can wrap a cool wet rag to act as a heat dam to keep the surrounding area cool. You can apply acetone after the heat and tap with mallet and a drift or punch to “shock” the fastner as the locker if still gripping should be quite brittle. With some paitence you should have success. Remember too much heat can anneal the fastner and make screws more prone to rounding out. Always use proper fitting and hardened drive bit for the fastner and take your time and dont hurry, because usually dont have the time to waste being hurried. 💡 😉
