i rebuild them all the time with a 12 ton press. lots to it other than pressing it apart and back together. measure the width of the crank before you begin, side play on the big end of the rod should be between .020-.030". you should cut the pin in half and press each side out individually to the inside. that way the munged up pin wont be pressed through the bore of the crank half. i made an assembly jig to press them back together true. they usually end up with only about .0005" or so runout. trueing the crank is critical. that cyl is plated, no sleeve. some plated cyls will attract a magnet, that one looks done for. time for a replate or sleeve job. honing grooves out of a cyl is never a good idea, cant do it on plated cyl anyway. even if it was sleeved by the time you honed the grooves out the piston to cyl clearance would be way too big.
