Early 1600 Driveshaft Flex Discs???

[coloincaalpine RIP 2021]

I'm almost positive that I have some in my flex disc stash. Don't know if they still have #'s on them but I'll take a look.

I have a 68 1600 (manufactured 12/67) and needed replacement flexes. I found an industrial flex with a bolt diameter of 75mm 24 mm width and 10 mm bolt holes. The flex is rated for 150ft lbs of torque. (1600 is 95 ft lbs). The worn flex measured 74.6 mm diameter, 24.5 bolt hole depth and 10 mm bolt hole. I purchased the flexes on line at Action Machine for $75.92 each. ( product number below) .I have not road tested the flexes yet ,but the fit is perfect.

The 1600 might be rated at 95 ft lbs of torque but the driveshaft sees Way more than that when multiplied by the transmission. First gear is probably around 3.5 X 95 ft lbs.

Thanks you are correct, I don’t know what it was thinking. The gear ratio in first gear is 3.8. The engine develops 91 ft lbs at 3000 rpm. So it would be 345 ft lbs. appreciate the help.

I posted previously about the flex from an industrial supplier. 
The torque data must have been incorrect Or Bmw Feels it will work. . I ordered the flex from BWW and received the flex yesterday. The flex from bmw cost $187.02. The product number On the BMW Flex is GA000-024 manufactured by SGF. It is the same product number as the flex I purchased from Action Machine for $75.92. See attached photo

If I recall correctly the first flex joint will needs to be replaced twice before the second joint goes out.  The second joint has to be replaced before the third joint goes out.  I had a 67  1602 that I put 167K on before I installed a 2 liter engine in it.  The flex joints didn't last as long with the 2 liter.

I’m in Germany and just bought a ‘67 1600-2.  In order to pass inspection, it needs all three guibos replaced.  Based on the above info, I googled “SGF GA000-024”.  
 

I bought three of them at €40 each (plus 32% tax) from E-Rubber.eu (https://e-rubber.eu/product/sgf-ga000-024-giubo-flexible-coupling/) for €172, including overnight shipping.

I am going thru the same issue.  Replacing all 3.  Did the SGF GA000-024 work (Same size)?

FWIW I ended up with 4 or5 new BMW pieces during my research. I've converted to a 2002/E21 5 speed setup, sold the 3 giubo driveshaft and no longer need them. Out of town until the 8th.

The GG000-024 fit perfect. No issues.
