Removal of old red loctite

Okay well i got these actuators and the ballscrews have a collar on the end with 2 set screws, which have loctite on there as well. Everything else in this actuator has been with red loctite, so i dont expect this to be any different. I've bent my allen keys trying to get these set screws out!

Is heat probably the best solution to loosen up the loctite? I suspect this is about 3-4 years old.

Acetone will generally deal to loctite. Squirt a bit on and leave it for a while.

Try the acetone solution before the heat, but the loctite web site says that red and green will need to be heated to be removed, while blue should come off with hand tools.
I can't believe they thought they would need the holding power of red.

For red you need heat. You don't need to get it red hot, just a little to hot to touch. If the metal has a little oil on it, it will start to smoke when you have it hot enough.
For really small screws it is a good idea to use heat even if the loctite is blue.

FOr what this actuator saw, i am very happy they used loctite. BUt it sure makes it a pain for me!
I will try acetone, i like that idea.
If that does not work, then its heat. And this is a small set screw, takes a 7/64 hex.

ugh! Every single threaded component on these actuators has red loctite! Including a 1"-13TPI screw. BUT, with enough force, the loctite broke.

When I fell on my Harley I snapped off a shift peg so
a mechanic had to heat the red-lockt stubb with a torch to get it

For small set screws you can use a small-tipped soldering iron to deliver the heat.

You can also ground the block that the screw is in, then just touch the tip of your TIG welder to the screw, that should get it pretty hot without resorting to the use of a flame.

I would really prefer not to grind the block. I want to keep this screw as it is right now, I just need to get it out because i have to buy more of the timing belts that are in there and i cant tell how many teeth there are because the whole assembly is enclosed. ALl i could tell is that its an XL pitch

He did not mean to grind the block, but ground it electrically.

Pending what it is ,sometimes you can use a drift punch & give a swift bop with a hammer & it will come loose or place an appropriate driver in fastener hole & bop it.
