Here's a little write up I did on dropping the pan and replacing the gasket.

I've replaced the main seal before. No big deal. You will need a torque wrench to tighten the rear cap after putting the seal in. Remember, keep everything as clean as you can. Years ago, when they had the rope type seal, they were a ***** to put in. The newer plastic ones slip in around the crank. I do agree with "Green Machine" though, to pull the engine if it is really dirty.
