[Closed] Gravity dropper stuck down

Like, really properly stuck down. Magnet actuates but pin is stuck in hole.

I know the solution is to loosen the top cap so there is enough play for the pin to pop out, but it's so tight I can't. Put some waterpump pliers on it, it just strips metal rather than turning the top cap. (This might be because I put thread locker on it because it kept coming loose...)

Any more suggestions?

bottom of the post is a bolt [ inside it] with an allen key that holds the spring in

UNdo that and this will remove all tension- this may not undo two of mine do one does not.
NB THE SPRING WILL COME OUT AT A GREAT SPEED SO APPROPRIATE CAUTION AND PPE IS ADVISED

IT WILL THEN BE VERY HARD TO RE INSERT

there is a plastic cap in there dont lose it [ may be inside may be stuck on the end of the spring] or the post wont work as it holds the spring against the dropper post and without it the spring twists round the pin. Its at the end furthest way from where you are removing the bolt

Few minutes work if it undoes easily

a towel over the end is probably enough to catch the spring

If you can't get that undone, the post will be useless anyway. It should only be finger tight, big pliers are likely to crush it and actually make it harder to remove. You might be better to cut it off with a file and replace the cap than to wreck the post itself.

Unfortunately I'm thinking the tension is there not because of the spring but because the cap is too tight, and the post is already positioned such that it can't be pushed down any more - is at the bottom of its travel. Is that plausible?

Yes, my guess is that the cap is too tight and the pin is jammed.

The other option is to send it back to gravity dropper.  My wifes went back to the USA when the magnet/actuator assembly fell off the post (before they improved it by adding rivets).  Didn't cost much compared to the total cost of the post.

Heat to try and soften the threadlock and then grip the cap at the very top, so that you don’t distort the threaded portion and actually make it tighter.

The best way to fix a too-loose top cap that keeps moving from its correct position is with a few wraps of PTFE tape, not a load of threadlock.

as spooky said. Sent mine back to gravity dropper and they did the exact same thing. Never had better service anywhere

I tried heating already. Reckon I'll invest in a strap wrench so I can get more force on the thing without mangling it
