Maintenance question for OM-1N

I picked up a near mint OM1n from ebay, and i really want to keep it in mint working condition but where i live (island nation) there are quite literally zero shops that specialize in vintage repair/maintenance cameras, let alone Olympus systems. And i dont feel like sending it overseas.

My question is basically this, is there any guide/video tutorial out there that shows and explains a complete CLA process for the OM1 or similar cameras? Im aware im no technician but i can follow specific instructions on my own risk, specifically what kind of lubricants/grease to use, when & on which parts, how to disassemble exactly whats needed and put everything back together. I tried youtube but it doesnt go much further than light seal replacements and prism foam cleaning.

Basically the most basic maintenance a professional would do to prolong the life of the camera.

Or at least as much as a regular person with normal precision tools can perform at home.

Thank you!
