How to get a ratio gear bolt off?

[ClausTj]

Hello,

After our first run in our "new" Radical SR3 a bolt inside the diff got lose and split/broke the housing, after X hours yelling at the diff we finally got it free, but the big bolt holding the ratio gear is stock.

If anyone have a trick to get it loose you most welcome

Thanks for the feedback, we will give it try.

Is there any risk trying to heat up the bolt, if we still cant get it lose?

Thanks, we might need to find a new impact gun the one we have "only" do 450nm.

But thanks again for your help.
