Gear Ratios for 210

[lastplace]

Hi All has any one found out what number of teeth are on the Main Diff Gear.
again no info in the manual on Internal Gear ratios
you would think that this is basic Information that should be in the manual
i was going to work it out as we know the other number of teeth on all of the other gears but no listing for the Diff Gear in the parts Listing so now stuck

with my eyes sight , there is no way i'm going to try and count them

cheers guys
