alpha one gen two hinge pins won't budge.... are there any tips to getting these things to free up?
I wrestled with bellows once before, and actually managed to replace gimble bellow and exhaust w/o removing the ring, but I need to replace trim senders and ALL the bellows this time- and I imagine it will be much easier with that dang ring off... so... how is it done if they are frozen solid?
I used heat (but not a lot, for fear of cracking the aluminum) and I used an impact wrench (1500#) and they won't freakin budge... they've been soaked with liquid wrench and I intend on trying again tonight... but I've gotta be missing something... anyone have advice?

do you have any idea how many hours of my life I've wasted trying to get that thing off and then failing, and having to get in all grades of awkward position to swap the two main bellows? let me tell you- zero fun...
tonight my hinge pin (x2) meets mr. "so dang hot you can barely see it" flame...
hitting it with heat yesterday wasn't so much as to break it free (not knowing about the red loctite) as it was to seep liquid wrench into the union...
i feel like I did when i drilled a hole in the hull- I'll do it, it'll just take a few beers to calm the nerves... <span></span>

i've now been challenged... it will break, I will break, or those bolts WILL come out.
i gotta get it off... I must replace the trim sensors- they got goofy last year, at the end, and it was because (discovered when I started this project) the wire is skinned and exposed. don't have a clue how.. my paws are far too big to reach up in there at the top of the yoke.. I may even have trouble with the ring off...
I've never encountered a more stubborn bolt. I'm at a crossroads right now... either I drill it out, or I weld the lug in there and try turning it again... I won't be able to drill it once it's welded, and I won't be able to weld to it partially drilled...
I hate these things... I'm using the word 'hate' and in it's true context. Two bolts have stumped me solid.
The only other thing I could try is to drive a 25~26mm hex into the head and try to turn it again.
already use 800# and heat they did not move. I really don't know how you are going to be able to get them out .
after you give it another try with an hex 25~26 mm and heat you probably have to try to drill them out not easy with SS.
Good luck
it is what it is- I won't be able to address it until Saturday... It crossed my mind this afternoon to drive a T70 into it, and see if JB Marine Weld will hold it... presumably, I'll be able to remove that fairly easy (relatively) and drill it out if it doesn't work.
Never. Ever. Ever. Have I encountered such a thing... no less than four highly competent people have also failed... it is thoroughly bonded.
I'm almost certain we came close multiple times to breaking the surrounding casting...
I've done the boiling water thing, the steam thing, a myriad of chemicals including lubes and even higher alcohol such as acetone and methanol (by product of another hobby of mine) and again, it hasn't budged even slightly.
It's comical at this point. The entire community is aware of it... apparently all the mariners are talking about it.. one dude who is trying to sell his marine repair shop said he's had several people ask to replace their pins when doing bellows cause they don't want to end up like this dude they heard about... that dude is me...
I hesitate to cut it, though that would work. I could then plop that thing on a bench and get the proper angle on it, maybe even use a press to push increasing diameter bits into it until it pops right out.
If it wasn't my boat, this would be funny.. and it still is, but not as funny as it would be if it weren't.
I've heard more metallurgical terms lately than I knew existed... the jest of all of them comes back to bond...
There is a guy doing some work nearby next week, and he wants to see it. He is apparently the welding master of the region. I don't know him, but a guy I do know knows a guy who knows him or something like that, and he just wants to see if he can do what others can't. I'm all for it... this hinge pin has defeated me...
Mother of all that's holy, this one freakin bolt is quite the story. Everything else went smooth, and in retrospect, too smooth... something had to make up for it, right?
