Ok, there seems to be info on this topic, but there almost seems to be to much so here's the deal.
Door appears to follow the contour of body well so buldge not really an issue
In need of the best method to perhaps move a 1/8" CC rotation
see pics
thanks
no screen door and the wear is a bit on the top of the pin. I do have replacement bushings and pins. A trick to remove old pins would be helpful as well.

The best trick to removing the pins is to use a lot of your favorite bolt freeing liquid every day for a week or two before you try and release them. Then get an air chisel and pound them carefully up. Hopefully they come out in one piece. Brute force is the only thing that will work. I did hear that Alex Birch (of screen door fame) used some kind of hand clamp. Not sure how it attached or if it was a custom tool, but it was like a small vise that he could use to push the pin out. Apparently that also was a slow and difficult process, but probably destroyed the pins in place a lot less frequently than an air chisel or a big honking hammer would.
I guess it goes without saying to be careful with the hammer or chisel not to destroy the side of your coach...

I dont know if i missed the beginning of this tread where u mentioned why you plan on removing the pin? Unless there is slop or play in the hinge itself there is no benefit to removing and replacing the pin.

I think the problem can also be stress cracks on the door at hinge attach point.

Erich,
I have used the following technique to remove the hinge pins, bumpers, etc from a few GMC's. First step is to take a glass jar and pour in acetone & transmission fluid in a 50:50 ratio. Shake the jar to combine the ingredients. The reason for using the glass jar is to allow you to see if the ingredients have separated; when that happens you just have to shake the jar again. Then you use a paint brush to apply the fluid to the hinge pins. Wait a few hours. Then take a hammer and punch and tap each pin upwards three times. Apply more fluid. The next day tap the pins again and apply more fluid. Do this each day until you see a space between the top of the pin and the door hinge. Then you apply more fluid and tap the pin downwards first then upwards. Continue this downwards & upwards tapping while applying the fluid two to three times a day until the pins release. Please note that this method only requires a hammer, punch, fluid and patience.

Pics wont load.... resized to almost no pixels and still get size limit ... and the trick is ???
thanks for the replies on pin removal. I have a couple air hammer options, will soak and start lite and progress from there
for the CC rotation, I'm not seeing any cracks in the jam side and bolts move properly when loosened and retightened. the upper bolt in lower door side isn't cooperative and there appears to be a little crack but cant tell for sure, I will pull the panel and check for cracking before cranking on it.

Erich,
If you decide to use an air hammer it would be a good idea to put something heavy on the side opposite you hammer on!!!!

In the mid 60's, I worked in a body shop for a while. The Kid (Me) got told to put the door back on an early 60's Buick of some kind and align it so it closes nicely.
I got the door from the paint shop and wrestled the bolts in so it would stay there, and then commenced leaning, lifting, pulling and pushing to get it to close nicely. It successfully resisted all my efforts.
Finally, in complete desperation, I went to the shop foreman and told him that I could not make it close as nicely as it should. He came to look at the situation and humpted "That is about as good as the adjustments will ever get it. It needs a special tool." and turned away. He shortly returned with a piece of 2X4 about one foot long. He swung the door carefully and looked at how it hit. Then he placed the piece of wood so its end was just over the lower hinge. He stepped back and grabbed the edge of the door with both hands and slammed it. I mean seriously SLAMMED it. It actually latched with the wood still in the hinge.
It took some effort on the door handle to release it, but when the 2X4 was removed the door closed as nicely and soundly as anybody could hope for......
Some memories just stick.

Indeed. A guy trued my bicycle wheel by the side of the road after I taco-ed it. He used a telephone pole for the initial truing. Rotate, eyeball, WHAM! Rotate, eyeball, WHAM! Thirty years later I still ride on that wheel.
