For the past 4 seasons, our main machinist ensured the 3 things you mentioned and we never had an issue with chain jumping off our drive ever. We basically set it and forget it, thus eliminating the need for adjustable bearing blocks and saving weight/time to make them.

Have you run a chain below tube/drive chassis/bellypan like this before? Do you run into issues with getting carpet junk into the chain or having the chain exposed to accidentally being hit on things? I am curious because we are considering running a similar chain setup, but don't have much relevant experience to base off of.
