• 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 metric ISOthreads according to DIN 13 and/or
ASME B1.1 threads, we recommend checking the tightening torque in individual
cases in accordance with VDI 2230.
In addition to the ports specified in Table 10 "Ports A2FO series 70" on page34,
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

1) The tightening torques for the threaded plugs are valid for the condition "dry" and "lightly oiled".
2) The tightening torques for the threaded plugs are valid for the condition "dry" – in the condition "lightly oiled", the tightening torques
for M10×1 are reduced to 10Nm and for M12×1.5 to 17Nm.
