450c pinion shaft

[76450c]

What size bolt goes in the pinion shaft in the final drive of a 450c to pull it out?

I am thinking 5/16 or 3/8 may be fine or coarse thread.

7/16 for the next person, weird both screws holding the brake drums to the pinion for the final drive were both broken towards the ends. Guessing they take so much abuse?

Coarse or fine thread?

Thanks for adding the info, it may help someone in the future.
