For special couplings on this vehicle, refer to 2.3.4.
If not otherwise specified, the tightening torque settings refer to clean, dry and ambient temperature threads.
Note. In order to avoid any possible deformation and/or wrong coupling, please tighten screws and bolts as follows:
- Snug all fasteners by hand.
- Apply half of the recommended tightening torque value and tighten the opposite parts: (A) and (B); (C) and (D).
- Repeat the above operation by tightening to the specified torque value.
Note. The pressure on the fastening parts will be thus evenly distributed on the coupling surface.
