Car makers do buy some subassemblies from different manufacturers. Also, there are also manufacturers for spare parts which may not be direct suppliers to the carmaker. So, one could find an alternator or winshield wiper motor or some other similar part that has non metric bolts. That's how the mechanic may come up with his statement. Also the part may have been changed during some service with a spare part which fits but has non-metric components.
I am sure that the design work is metric based. As well as basic components. I had a friend in Canada who worked in design at Chrysler in Windsor or Detroit. Unfortunately we lost contact and at the time I wasn't interested in US metrication so I didn't ask. I will try to find him and ask. You are too pessimistic John! It's not soo bad! (It's worse!) :-) A. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of kilopascal Sent: Sunday, 27 January, 2002 20:03 To: U.S. Metric Association Subject: [USMA:17691] Re: Is joining USMA worth it?... 2002-01-27 Joe's comments about the auto industry bring up an important question. Are the industries that went metric 20-30 years ago still that dedicated to metric today? I really don't think so. I've seen lapses that should send up flags. Concerning the auto industry, I have come across many instances where metric is not used. First of all, there is the every-now-and-then argument by Joe Home Automechanic that his 1999 whatever still has non-metric parts on it. How he can tell, except for nuts & bolts is beyond me. Just by looking at the car, how can anyone tell if the fender, or hood, or doors, etc are metric or not? But, most of all, they are referring to the nuts & bolts. Do they really know or are they assuming a bolt is non-metric because they can fit an English wrench on it? Second, is the after market parts makers. Do they adhere to metric when making after market parts? A few years back I was in line at the local auto parts store, behind a guy who wanted to return the after market part he bought because he thought it was defective. Seems the bolts wouldn't go into the threaded holes. The clerk tested the guys bolts in his unit and they fit, then into the new unit and it would not thread in. The clerk went over to his parts bin and picked 4 new screws and Voila they went into the after market part but not the OEM part. The old bolts were metric, the new ones were not. Third, a neighbour who works as an inspector for Ford Motor Company claims metric is not used where he works. Is it possible the drawings are "converted" for the sake of the Americans at American plants? I can't imagine hundreds, if not thousands of union factory workers of the same mentality as Jim Elwell's "plumber", happily using metric on the job. Somehow these people must be shielded from metric, but how? Since I have never seen an automotive drawing, I can't say for sure what goes on in these plants. If anyone knows, can they enlighten us? For whatever reason the auto industry went metric in those days, and other industries too, like soft drinks, one must wonder if the use of metric is still strong and uncompromising in these industries? Even though the soft drink industry introduced metric sizes in that era, we have seen reversions back to FFU since. When some of us asked Coke and Pepsi why they introduced 20 and 24 ounce bottles, all we got was that same old tired "market-forces" excuse. Let's face it, the people who worked in those industries 20-30 years ago and introduced those changes, are either retired or dead by now. The newer generations hired on since don't have that feeling for metric as the previous managers did. I'm sure many of the present work force would rather return to all FFU. I'm sure this new generation is not metric fluent and to them metric is a nuisance, and thus are more tolerant of contractors or vendors who don't stick to the strict use of SI. Any comments?
