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 11.
• 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 11.
• Mounting bolts:
For mounting bolts with DIN 13 metric ISO threads, we recommend checking the
tightening torque individually in accordance with VDI 2230.
In addition to the ports specified in Table 10 "Ports A4VG series 35Series 35"
on page 41, axial piston units may have openings that are also closed with
a threaded plug. These plugs must not be opened on the customer side! If you
have opened the threaded plug accidentally, please contact your local contact
person to ensure safe re-closing of the plug. You can find the address at
