Yes you could make it completely mechanical but routing the pto shaft might be dificult. The leaking oil is not from the shaft seal but from the gasket that seals the end cap housing. It did not leak until i overfilled the winch after i removed the bumper. All it would need is to be resealed on that cap. I replaced the shaft seals last year when i got the winch. Any other questions feel free to email me too
