It's a 15/16" bolt (the sump plug is essentially a bolt which you take out to drain the oil). When you say 'it already is a 24mm head' do you mean that the bolt I'm talking about is not 15/16" and I did not buy a 15/16" socket and the instructions/guides etc don't say to use 15/16" socket? I'm a little confused by what you mean.
Folks - is 'sump plug' yet another word that fails the 'divided by the same language' thing? ie UK versus US english?

To: [email protected] The difference between 15/16 inches (=23.8125 mm) is 0.1875 mm. This difference is equivalent to the upper end of the diameter of human hair. If the difference is spread evenly over the faces of the head, then we are talking about a difference of 94 µm. Definitely not enough to round the points. The difference between 10 mm and 3/8 (9.5 mm) i could see causing a problem, but definitely not your example, especially since it already is a 24 mm head.

It's 15/16ths - I tried fitting 'close' other measures but it wont't work. The reason I tried it because buying one 15/16" socket for one sump plug is uneconomical. But I ended up buying one from Halfords because I did not want to risk rounding off the nut. The socket is marked 15/16" because that's the size of it - as is the sump plug. That is, 15/16". I carry both metric and imperial spanners so I never have to bodge a job just because of some odd idea of a measurement war extremity.

To: [email protected]; [email protected] I had no idea what a sump plug was, thinking it may have been a British term for spark plug. 15/16 sounds like an odd size and thus seems like an approximation for 24 mm. This web page on sump plugs is all metric which leads me to believe yours is too. http://faq.f650.com/FAQs/Sump_Plug_FAQ.htm This page says that both wrench sizes will work: http://faq.f650.com/GSFAQs/GS_Oil_Change_FAQ.htm I'm sure your instructions said 24 mm or 15/16 in and you omiited the part about the 24 mm.

It's a sump plug. And it's 15/16ths (not 5/16ths). Does this help? Date: Sat, 14 Mar 2009 06:53:05 -0700 From: [email protected] Subject: [USMA:43808] Re: Jerry's questions regarding "imperial" fuel & fish sales in the UK. To: [email protected] 5/16 is 7.9375 mm. An 8 mm socket would fit and the less than 0.0625 mm difference would not be noticed. I have also seen 1/2 inch wrenches and sockets fit a 13 mm head even though the 1/2 inch is smaller then 13 mm. It would seem that the 1/2 inch sockets are really 13 mm ones in disguise. Thus I would not be surprised if a socket labeled as 5/16 inches was really 8 mm in disguise. According to this thread: http://www.smokstak.com/forum/showthread.php?t=57707 Spark plugs are metric, so it would be a true 8 mm. You can even buy spark plug taps with a metric thread. Here is a whole set of spark plug taps, all metric: http://buy1.snapon.com/catalog/item.asp?item_ID=9721&group_ID=1154 Or are you trying to tell us you still drive a model T which did use inch based spark plugs?

Funny. All of my cars have been manual transmissions (including my Audi Allroad and my BMW 540i...both 6-speed manuals). It took me getting a British vehicle to have an automatic. :) (A Range Rover Classic I picked up for $500, fixed it up a little bit and have since put 16,000km on it since I bought it a year ago.) I wish it was a manual transmission, but they never imported manuals to the US. But, I have 7 other cars, and they are all manual transmissions....
