I used a 21mm on mine yesterday. hope this helps Paul
You will need a 35 mm socket.
Need to know the year, make, model and engine size to help you with that one.
5/8"
You need a 14MM Allen key or similar sump plug key.
I believe it is 16mm
15 mm
35mm
13/16" - at least that is the size for my honda 520S snow blower.
You will need a 5/8 socket.
I can't remember exactly but its big (for a drain plug) somewhere around 17 or 19mm.
You'll need a 5/8" socket.
