working on a long 445 wich if my info is correct the ac 5040 and some fiat and olivers are exact same. want to change oil in final drives but not seeing a distinct drain and fill plug. just 4 big bolt heads on inner side of final drives. didnt wanna remove something im not supposed to. thanks

I sure hope the lower plug that you're talking about is the oil level because that's where I fill my Oliver 1365 to. I just put the oil in a 1 quart squeeze bottle and shoot it in until it's at that hole. I didn't fill it from the top hole. That seemed a little unnecessary.
