angusb Posted June 21, 2020 Share Posted June 21, 2020 Although the Specification booklet states " Propeller shaft " M10 12.9 grade material torque to 83Nm , does not differentiate between earlier and G50 boxes,when come to put mine back together , will torque to about 45nm Link to comment Share on other sites More sharing options...
reddevil Posted June 21, 2020 Share Posted June 21, 2020 45Nm does seem quite low - I needed the impact to get them off - and the driveshaft is date marked 1987 so may have never been off the car! I've ordered new genuine bolts so will see if they come as 12.9 grade. Link to comment Share on other sites More sharing options...
tea boy Posted June 21, 2020 Share Posted June 21, 2020 The earlier cars had m8 bolts, that’s why they have a lower torque setting. Late 915s and G50s had the m10 bolts along with the same inner CV joints as the 964 and 993. If you have m10 driveshaft bolts the 993 torque setting is the one to use. 2 hours ago, angusb said: when come to put mine back together , will torque to about 45nm That’s the wrong number dude. 1 Link to comment Share on other sites More sharing options...
