That was a great suggestion and got me thinking. I tried to rent the puller but the tool is too short to reach behind the pinion gear and press off. But doubling the cups allowed me to do what i needed done. I bought two pullers for about $50 off of Amazon and welded the cups together. Added some thin aluminum shims to press the cups tight against the pinion gear and it pulled off beautifully. There was no way to remove this pinion gear without some type of puller like this. Since the original tool is now made of "unobtanium", this fabricated puller is easy to make and readily available. Thanks for the suggestion!
