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.
