Transmission Torque Specs
« on: 22 October 2019, 07:12 PM »
So, I’m working on putting my 1979 300SD back together.

I’m wondering if anyone can give me the torque specs, particularly for the nose cone bolts and the output shaft yoke and Flex Discs.

Thanks,
John

The nose/tail shaft cone bolt torque specs are 1.3 mkp/12.74 Nm/9.4 lb-ft. The output shaft yoke is 12.0 mkp/117.68 Nm/86.80 lb-ft, and the flex disc bolts are 4.59 mkp/45 nm/33.19 lb-ft (they should be M10 bolts [10mm thick shaft]). Otherwise the book calls for 6.63 mkp/65 nm/47.94 lb-ft for M12 bolts.

Thank you Squiggle Dog. It’s all buttoned you, and so far, no leaks!
