 Topic: Removing 2007 era stanchionsPosted: 06 November 2020 at 10:25 |

Hello all;
I am in need of removing some of my stantions thanks to getting them bent in a storm last year. So the boat is a 2007 430 with the aluminum stanchion sockets and the stainless stanchions. Do you know of a way to remove the stanchion? sure the side bolt comes out but it seem the stanchion and socket are now one. I have tried heat, penetrating oil, big wrench, etc and nothing even moves. The black plastic liner seems to have not helped to keep them from corroding together  |

same solution on my h400 from 2006. Just removed the M6 screw and lifted the stanchions. Somewhere I saw a picture with a home built tool to remove it. A pipe outside the stanchion swith a slot at the lower wire hole standing at the foot. Then a hydraulic jack on top and a chain Connected to a bolt or pin in the stanchion hole.

The bolt should have been plastic. Someone have changed it and it have caused the corrosion.

No, the original bolts are SS steel.

The hydraulic jack and pipe seems like a brilliant idea, and I could fabricate that. but my stanchions are damaged and I do not have the facilities to build that tool. Any other ideas on how to remove them are welcome.

I see that you have tried heat, have you tried cold? There is a product available in the U.K. called Freeze and release, I used it in the past with success. Please keep us all informed of how you get on as I also have one to remove.
Best of luck

I had the same. In the end I oversize drilled the hole where the bolt went through. Loop of dyneema through the guard rail hole. Then a slide hammer connected and used vertically & upwards. It came out reluctantly but it did release. To refit I used a longer bolt & an external nut. Both liberally covered in duralac. Then a power boat took out the stanchion completely but that’s another story :-)

Mine did come out with heat as I poured boiling hot water on to just the aluminium part of the base.
In my case, I had bent the stanchion. As I stepped off onto the pontoon, the hem of my jacket caught on the stanchion and I ended up upside held just by the the jacket. I have now fitted stanchion covers on the 4 stanchions that are close to the shrouds. It must have looked serious, as just for once, my wife did not laugh at my predicament.

Still working on this and I am considering replacing the bases/feet as well. Does anyone know how the base is attached to the toe rail or deck? is there a bolt from the bottom through the deck or are the bases connected mechanically to the toe rail?
Any help is greatly appreciated. going to try more heat on just the base today and more penetrating oil. Frustrated!

On my 2006 Hanse 400 there is a bolt in the foot with a washer and a nut from the inside. From what I remember the bolt is fixed in the foot (hexagon shaped hole) so you can probably unscrew the nut without access to the head. I found the picture of the tool mentioned in my earlier post. Should do the job without damaging the boat.  |
