Final drive removal on 2018 Nortrac 35XTD

Hello I’m new here just reaching out to see if I can find some information on exactly where I need to split the final drive off the transmission. I’m new to dozer work. I have the ROPS  off ready to pull off the right saddlebag I need to replace the upper gear which is called the semi gear per the manual The parts in hand just don’t quite know how deep I have to go. Can Anybody point me towards somebody else’s issues or share some photos that be great thanks in advance
