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 19.
• 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 19.
• 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 16, Table 17 and Table 18 on
page44, 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

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.
