deere 750c final drive leak

I've got a deere 750c dozer that's got a leak in the left final drive coming from in between the inner and outer final drives. It was just slight at first but now anytime it sits there's a puddle. I'm sure there's a seal in between the 2 but is there a way to fix it without having to tear apart the entire final drive or a way I can band aid it for now? Thanks guys
