Can it be tapped loose or will it just get stuck worse

Just for a temporary fix Antfarmer, put a loop hose on the aux couplers so it won't build pressure.

Mine is a different location of course but it was sticky also a year ago and I got it to move just by working some penetrating oil and wd 40 in by squirting it on the spool end and jiggling the lever. There are little balls and springs the do the detent and that is probably what is sticky.

By the way, you don't still have the 3/8 lock bolt in the lower part of the stick do you?

Remove the cap on the back of the aux hydraulics too, see if there is anything rusted up.
If it's stuck well enough for you to not be able to move it, you will need to pull the spool out to clean up the rust as it will cut the seal up. Then you may have issues with it leaking......

Hey Tazza if I pull the back cap off will springs and balls fly and can it be put back with out pulling the spool if it was just stuck there the rubber on the front looks brand new was thinking about useing a horse needle to put some oil in there do not think it was ever used what do you think

A search of this forum for “detent” turned up a lot of posts and I think you should contact old machinist as he had one post about a 863 that sounded like you need to follow a specific procedure to remove the balls and replace them.

Will do thank you

If you remove the E clip on the back of the cap, push the middle part inwards while sliding the cover off, the detent balls will stay in place.
The needle may work, but i'm still concerned that if it has rusted up, the rust will chew up the seal and you will have a nasty oil leak. Either way, if you plan on using your aux hydraulics, it needs to be freed up.

Right now it will not move at all do you think if I remove the clip it will move?

I doubt it will move, but if there is rust in the rear cap it may need some oil too.

Will spinning it help?

Possibly, if you can get it to move
