The oil pump can be serviced by removing the oil pan. That entails several hours work so if paying to have it done expect a substantial bill. Your problem us a common one and there is no guarantee a rebuild kit will fix your problem. Paying professionals to maintain 70 year old tractors makes them expensive toys.
