Gear Box Torque

According to the Illustrated Parts Catalogue, the gearbox mounting bolts are a mix of M6 and M8. The Heavy Maintenance Manual then lists the torques for these sizes as:

M6: 10 Nm (90 in lb)

M8: 24 Nm (17.7 ft lb)

These torques are not overridden by anything else that I can see in the manual.

Thank you Kevin
