I'm in the process of re-building a blaster. I found this forum and it has been a great resource, so thank you all.
Any how i compiled a list of bearing parts numbers for crank and trans case.
Left side case:
a. Left main bearing - 83a915 koyo
b. Left counter shaft - 6304 koyo
c. Left main shaft - tr152512 e02 IXO
d. Left balance shaft - 6202 koyo
Right side case:
a. Right main bearing - 6305r1 koyo
b. Right counter shaft - 15nQ2812 koyo
c. Right main shaft - 6204z koyo (half shielded)
d. Right balance shaft - 6203 koyo
note: The left main shaft bearing i ended up getting through yamaha, the yamaha part# is 93311-31567.
Im not positive if the stock bearings were koyo, im sure some one out there could confirm or deny that. But i know that the case on the beat up old quad i got has been cracked open before. So its possible these are not the original bearings. But those are the numbers that i used successfully.
