Well. I did not take any pictures, But the job is almost completed, We are painting the tractor and doing a lot of repairs along the way, we removed the rear fenders, Blocked up the tractor securely, removed the rear tires and wheels, also remove the draw bar and draw bar brackets to create more room, for vision and swinging the hammer, then it gets interesting, you need:

1 punch as close to the same size of the pin as possible 2 inches long, held by a pair of vice grips, Cut the pin thru the inspection hole, As much as possible, without damaging the brake brackets, Beat on the pin to drive thru until you run out of punch. Re-cut the pin, Have a second punch 3 inches long, same size in diameter as previous punch, this should drive the pin out of the housings, If the pin was cut cleanly with the torch? brake brackets should come off of the remaining pin and drop out of the inside housing hole. Brake shoe brackets should pull out the top inspection hole, Use the largest hammer you have with the shortest handle possible. First brake and pin was learning an took about 4 hours with 2 people, Second brake and pin about 2 hours. I really think now I could get it down to about 1 hour after doing the first 2. PS, Big hammer create a very sore arm!!!!!!

Steve,
Nice work getting those WD brakes done. You should never have to do them again!
Get us a few pictures when you get a chance. Keeps us going. Always like to see what others are doing too. Sometimes inspires us to get moving.
Regards,
Chris

I did the weld on slide hammer thing. It worked. I heated up the pin and poured the WD-40 on along with some oil. Still had a sore arm. I replaced my pins with Stainless tho.
