How can you tell by part numbers between 13 and 15 wide gears and hyvo vrs non hyvo? A lot of gears share the same middle numbers with the tooth size in the number but the prefix is different. I'm searching for different 13 wide top gears.
non hyvo 13w will be 89J. 15w non hyvo(dont think there ever was a hyvo in that style) will start with 8DF. all the 13w hyvo's will pre-fix 8DW.
