I have to return a stepper motor but it's attached to a worm with a set screw. The loctite just won't break with the tiny allen wrench (3/32"). I have my soldering iron set to 899° but it doesn't seem to be working. Is that not enough heat? Should I do a couple heat/cool cycles? Tips appreciated.

You need a quantity of heat, so your iron is probably too small. Usually I use a small soldering torch, or an 80 watt iron. The torch definitely works best. If using the torch you may have to shield the components with aluminum foil, sheet metal, or other material.

They used blue loctite. I should be able to muscle it but the allen wrench is too small.

If you can do so without damaging other parts with a stray flame, try a little butane torch to put the heat on it.

Between hot & cold cycles, try adding a drop of acetone or MEK.

I got medieval on it. Wrapped the motor in foil applied a bit of torch. It still needed muscled off but it snapped free.

Thanks for the tips.

Loctite sells the stuff that removes their adhesive.

With regards to the heat, I think the rest of the motor is sucking away the heat from the area.

But I see that you've taken it off already.

Next time, on such small screws, stick with purple. Or use a dab of nail polish, instead.

Yeah, I get they are going for stability but the loctite was a bit much. I'll take your suggestion.

Since it is a small set screw, use a fine tip soldering iron for localizing high temp. Will come right out.

No can do. It's maxed. 900 must be dangerous or something.

I must have an error on my chart. It calls for only 6 oz with blue locktite.

Red Loctite is almost impossible to move.
Blue can move with application of heat and muscle.
Easier to use nail polish if future removal is desired,

In my experience, Red Loctite IS impossible to move.

According to the loctite website....

Clean adhesive residue immediately with a damp cloth. Cured product can be removed with a combination of soaking in methylene chloride and mechanical abrasion such as a wire brush.

For disassembly, shear with standard hand tools and remove with methylene chloride. In rare instances where hand tools do not work because of excessive engagement length, apply localized heat to nut or bolt to approximately 482°F (250°C). Disassemble while hot.
