Kubota b7300 hst rear main seal

[Swmmsc]

Howdy, new to the forum. Looked under Kunis topics and found a way old, 15 years, thread with some pictures but not much info. I have black oil leaking from the bottom start bolt on my tractor. It's leaking alot too. From what I've found it's the rear main seal. I'm decently mechanical but never torn an entire tractor apart. Is there some more detailed instructions on what NEEDS to be be taken apart? Any advice? I'm certain there are lots of things that could be replaced or fixed while it's all apart but i don't know what. Does the seal need to be pressed in? Specialty Specialty required? Is it just unbold everything and then put it all back together with the new part? Gaskets? Etc Any advice and tips would be great. Thanks
