The following tightening torques apply:
• Fittings:
Observe the manufacturer's specifications regarding the tightening torques
of the fittings used.
• Female threads in the axial piston unit:
The max. permissible tightening torques
M
G max
are the maximum values for the
female threads and should not be exceeded. For values, see Table 13.
• Threaded plugs:
For the metallic threaded plugs supplied with the axial piston unit, the required
tightening torques of threaded plugs
M
V
apply. For values, see Table 13.
• Mounting bolts:
For mounting bolts with DIN 13 metric ISO threads or ASME B1.1 threads, we
recommend checking the tightening torque in individual cases in accordance with
VDI 2230.
