15.2 Tightening torques

All the tightening torques are intended in Nm.

Tightening torque tolerance: ±10%.

The tightening torques are based on a friction coefficient of 0.12 with a lubricated fixing elements (bolts or nuts) threads.

After long operating times or use at temperatures above 80°C, the breakaway torque may be significantly higher.
