Hi, This is my first post to this forum so I hope I don't offend anyone by asking a stupid question up front. Can anyone tell me what type of gear oil goes in the transmission on a YM 177? The capacity? What type of engine oil is recommended? My dad used to put Rotella T 40w in his compact Ford tractor. By the way, this Yanmar belongs to a family friend and received it in a divorce settlement. They had 2 but bought in auction without manuals. Thanks, Andy
