ac clutch will not draw back in on its own.

When the ac clutch releases to the out/off position it looks to be kicking out farther than it should and it will never reengage. If I turn the car off and pop it back in it will work fine, until it shuts off again. I was told that the ac compressor on my model and year doesn't have to be completely changed, I can just change the field coil. I was also told that I could just unscrew the bolt attaching the clutch plate and pull it out and remove a pin of the post that would keep it from releasing too far for it to be drawn back in. Any help on this issue would be greatly appreciated.
