Crawdad got it right. Heat, wisely and strategically applied, works wonders. I have even gone to the extent of applying ice to the lower exposed section of the shaft, avoiding the arm. This will help shrink the center making the heat on the outer more effective when it expands the arm while also slightly offsetting the conduction transfer.

Repeated heating cycles may eventually raise the shaft temperature higher than we want. Make sure you wait 30 minutes between attempts. A spray bottle with water will help cool it faster.

Try it first with heat as Crawdad suggested. If it doesn't work, remove puller, allow 30 min for cooling, apply ice (10 min), install puller, apply heat and beat that mofo.

Propane is great for the lower temp we want but won't heat the arm fast enough before it begins to transfer to the shaft. MAP gas or a broad oxy application will do well to expand the arm quickly if used with care.

Instead of a sledge or ball peen, try an air hammer. If you don't have a blunt tip, use a piece of flat stock between the air hammer and arm to prevent unwanted damage to arm. Only hit it on the outer circumference to prevent damage to the box.

If it doesn't pop after 10 minutes of propane application (5 minutes oxy) , stop and begin cooling arm and shaft with a spray bottle of water or wet rag to prevent over temperature, tempering, and seal damage.

Good luck. Keep us posted.
