your crank should not have any pay in it rite. got blaster #2 today and i think they are out .what is the best way to tell if they are out?where is the cheapest place to get them?
Page 94 on this manual http://www.rydindirty.com/blastermanual.pdf it shows the exact specs, it does have some play depending on which part of the crank. You can get cheap on ebay, ive seen good used ones for 50 and new ones as low as 100.
you won't need a whole new crank. just the bearings. they're like $20 each side. then you gotta replace the seals too.
do you have the tools needed to rebuild the bottom end?
