Oil drain plug size (610)

What is the size of the drain plug socket-female (the inny not the outy) on the 08 610?
3/8" has got wiggling room so is it a 11, 12mm?
I've spend the whole morning looking for those sizes, thinking I'm just gonna buy a 10, 11 and a 12mm and return the ones that don't fit but nobody roundhere has anything over 3/8 so I'll probably need to order something
Thanks for the help

10mm = .3937

3/8 = .375

Is it a 10? I could swear I used a 12mm.

Then again I've been working on a lot of small engine projects lately so I could be thinking of something else.

you could be right. I was just helping with the math...

If you get a second and don't mind, will you check it for me?
Many thanks kind sir

There are of course two plugs. The left side has a 12mm head and the right side has the 10mm hex(aka Allen) head.

I'm talking about the one that you need to fit (shove) the wrench inside, which one is that?

10 mm allen wrench or bit for this one



Regular old 12mm wrench or socket for the other one

Yes, that's the one
Thanks

Glad you're good, man. That pic was hard to take with a phone upside down and a trouble light in the other hand, trying to line up the holes on the bash plate, all while my liver was processing a few

I knew one of them was a 12

I didn't have a 10mm allen socket so I used a regular "L" shaped allen wrench and sliced a nice gouge in the side of my hand on my skidplate when the bolt let go. I went out the next day and bought a set of metric allen sockets.

I have a set of Craftsman T-handles as well from 2.5mm to 10mm. I get a lot more use out of them than I thought (I also have bicycles to wrench on).

Yeah, the T handle ones are nice too. I also ride the non motorized bikes, I've got a Trek 7700 for the street and an Ibex Ignition for off road and my Wife rides a Trek 7200.
