    I wonder if it was overloaded enough to bend the pin, and what part that would have played in the series of events.

    I'm sure if the trailer could talk it'd scare the hell out of you. My uncle used to get machinery loads from the outfit that had it before me. Said that it had a flip on it just about all the time, and more than once was hooked to a jeep.

    That used to be the way with shafting, all the raw material came rough, so a 4" rough piece of stock trued out to 3-15/16, about a 30 thousandths cut and polish it in.

    Eggzactly....probably 4140-ht, tough enough, but at Rockwell Rc28-30 still machinable, and not going to shatter.

    Would I be correct in assuming it'll take grease this time..?

    It better. What are your thoughts on making a grease groove around the inside? I have a deburring bit that looks like a BB on the end.

    I think I would put the pin in first and try greasing it and observe where the grease comes out. If it all tends to come out of the housing at the top where the grease fitting is located then you can pretty well guarantee the bottom of the pin isn't getting greased. That would make it a prime candidate for creating some sort of grease groove around the inner surface of the housing. A shallow groove maybe about 1/16-1/8" deep made with your deburring tool ought to work. All you need to do is get grease to move from the fitting location at the top of the housing right round the surface of the pin before it starts heading outwards.

    Question: Does the pin tend to "walk" around while the trailer is in operation..?

    There are three fittings per boss, as the pics in post #27 show. It was a breeze to put together. Pushed it in by HAND up to the other side. A few taps with a 8# sledge and it was through. Greased up, could turn the pin round and round with my pliers on the bolt. Could not possibly have went any better.

    I think you're golden.... I would bet the trick is to keep a grease gun in the gooseneck, give them all a shot when you have it disconnected so there's no load at all on the pin?

    YA BUDDY. :beerchug Now if I could just find someone that will chip in for the $2000 bill to cut the old pin out. The guy was all smart@$$ when I called him, says "No problem, I'll blow them right out with the air arc." I said, "They are about 5-6" long, 4" in diameter." NO PROBLEM. Took him all day, 9 hrs, ended up cutting two with the torch.

    I've done pins with an air arc, it's murder after the first inch. The air stream flows down alongside the carbon rod, it's designed to go sideways, not straight in.

    The piercing setups work because the air or oxy stream is in the center, you can work it right on through.

    Mag drill might have been a better bet, in 20/20 hindsight, drill it through, then drill it bigger, then use the biggest cutting torch tip you can get and blow it on out. After a bit you could probably let it cool and it would shrink and knock right out. File that for the next poor sod that has to do this.

    I as going to ask how that went, if you had known that going in you might have been able to burn away at it yourself eh?

    At least it is back together and will never be a problem again.

    The answer for long large diameter pins is always the good old thermic lance ......

    I'll second Nige on the oxy lance, burned several pins out of excavator booms with one, hot miserable work but nothing else will come close to what it will do.

    Agreed. Sometimes in the bush though, you gotta make do with what you got. Still, 9 hours?

    It was a judgment call. Hire the work and keep working myself, or stay home and fix it. Moneywise, it was probably a wash, plus I still have my hair and eyeballs.
