Can't help with the accessability to seal in F2 but I can tell you how we normally replace seal. If there is no sign of leak between intermediate plate and block we will take a short cut. If leak between block and intermediate plate we will want to remove front cover to get at and tighten bolts. If not we will weld a couple nuts to seal so we can use plate across end of crank with a couple pieces of ready rod to pull old seal. We will then reinstall with pipe that fits new seal OD and then pull in until it bottoms with threaded rod using crank threads.
