Roofus Posted December 20, 2023 Report Share Posted December 20, 2023 Hello, what is the thickness of the clutch disc on a M6 box? On the manual, it is indicated .125 ", I do not understand this value Quote Link to comment Share on other sites More sharing options...
soth122003 Posted December 20, 2023 Report Share Posted December 20, 2023 It's 1/8 inch. The value for thickness on these old cars is measured in thousands of an inch. It is a digital representation of a fraction. I believe most blueprints and engineering specs use this. You can just google the conversion charts and input the digit and convert to a fraction or in your case metric. Since your in France, you use the metric system. In the U.S. at the time of these cars S.A.E. was the standard unit of measurement. Joe Lee 1 1 Quote Link to comment Share on other sites More sharing options...
Sniper Posted December 20, 2023 Report Share Posted December 20, 2023 .125 inches works out to 3.175 mm. So your disc, when new, should be 3.175 mm thick. 1 Quote Link to comment Share on other sites More sharing options...
Jerry Roberts Posted December 20, 2023 Report Share Posted December 20, 2023 1/8 inch is a VERY thin disk . Something is wrong here . Perhaps 1/8 inch of material on each side of the disk . 1 1 Quote Link to comment Share on other sites More sharing options...
kencombs Posted December 21, 2023 Report Share Posted December 21, 2023 (edited) I think Jerry is right, and that is new specs, not wear limit. 2 hours ago, Jerry Roberts said: 1/8 inch is a VERY thin disk .

soth122003 Posted December 21, 2023 Report Share Posted December 21, 2023 If you're reading a thickness of .125" it is probably the clutch disc facings. Those polygonal rectangle shapes that are on the disc. I replaced my disc this past summer and my new disc was about .325" thick. It was over 1/4" and less than 3/8" thick. Probably about 1/4" for the facings and 1/8" for the disc itself. I don't really remember except the new disc was about twice as thick as the worn out one.

Roofus Posted December 21, 2023 Author Report Share Posted December 21, 2023 (edited) OK, it would therefore be the thickness of the garnish (to be multiplied by 2) plus the support? 1949-1950 CHRYSLER C-45 THRU C-50 SHOP MANUAL.pdf Edited December 21, 2023 by Roofus Quote Link to comment Share on other sites More sharing options...

Dodgeb4ya Posted December 21, 2023 Report Share Posted December 21, 2023 Here is a NOS M-6 MoPar clutch disc measurement, .330" Notice how close together the discs are to each other. Each facing is yes .125". Many rebuilt discs today are too thick causing adjustment issues. 1 Quote Link to comment Share on other sites More sharing options...
Solution Roofus Posted December 22, 2023 Author Solution Report Share Posted December 22, 2023 Thank you all for your answers, can you advise me a dealer? I only know "Andy Bernbaum" but maybe there are others ? Quote Link to comment Share on other sites More sharing options...
soth122003 Posted December 22, 2023 Report Share Posted December 22, 2023 Since you didn't specify a model for you car, Andy's is probably your best bet. A quick check for clutch parts on the search engine shows that most ads sell kits. If all you need is the disk, Andy's has them for about $115 to $150 depending on the size. That was my case. I didn't need the pressure plate so And's was about my only option as most others sold a kit with the plate included. Joe Lee 1 Quote Link to comment Share on other sites More sharing options...
kencombs Posted December 23, 2023 Report Share Posted December 23, 2023 I would search this site for info on Tennessee Clutch. They have done work for several members and even with shipping the prices were excellent. Quote Link to comment Share on other sites More sharing options...
andyd Posted December 23, 2023 Report Share Posted December 23, 2023 As the original post is from France, I'd be checking British clutch companies also Swedish companies....much closer & should have listings....& yep that measurement, .125 or 1/8th I've always understood it to be the clutch disc lining thickness on ONE side.....regards from Oz.......andyd Quote Link to comment Share on other sites More sharing options...
