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 12.
• 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 12.
• 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.
