My Bucket is 3/16 on the sides. thicker on the bottom of course. just a rough idea on the weight of the bucket. yes I guess those boy's in NC don't want any thing coming loose, eh?. I managed to get the dipstick loose after using a Hammer and screw driver, I bet I don't put it back as tight. LOL. I had to go to NH dealer ship to buy a special Hex wrench to get the drain plug of to change the oil, on my old TT75A. what ever happened to the old 'Nut' they used to use. no special tools needed.
