Hi All, I have a SCAG Turf Tiger that has a hydro gear BDP 16A-307 pump. The pump has developed a leak around what looks like a plug of some kind. The pump is still on the mower and I m hoping the leak can be fixed without removing it. I have another pump (a different but similar one from a Tiger Cub) from which I have removed this plug to take pictures. There are 2 pics of the plug and a pic of the pump showing where the plug was removed from. Does anybody know what this plug is called? If it is leaking, is it a matter of just replacing it while the pump is still on the mower and just replacing the oil lost? Anybody know where you can order this part and possibly a part number? Sincere Thanks for any help.
