Taking apart Constant Speed Solenoid (CSS, Lift Magnet)
mnahon:
I'm wondering if anyone here has taken apart a constant speed solenoid (CSS), also known as 'lift magnet'?
I have a CSS that half-works. When energized, it starts to extend, but then binds. My impression is that the shaft may be bent, so I'd like to take the CSS apart. However, there's no obvious way to do this. I was wondering if someone here has done this before and could give me some guidance. I could post pictures of where I'm at if anyone figures they have an idea.
Thanks,

New these seem to list at over EUR 1,000 - but in Niemoiller's catalog it appears to refer to these as 'rebuildable' meaning you have to pay them EUR 1,000 as well as return your old unit. I recall a long time ago a discussion on here where someone may have reported having succeeded in rebuilding one, but I am not sure.

See my post Dec. 23, 2016
I disassembled it, repaired it and it has worked since
Attached see pic of disassembled solenoid. There is a brass washer for a stop and I replaced it with a thicker one. Works fine now - no stickum. Current draw before modification 1.02 amp, after installing thicker washer 1.03 amp
