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 maximum permissible tightening torques M
Gmax
are the maximum values for the
female threads and should not be exceeded. For values, see Table 16.
• Threaded plugs:
For the metal threaded plugs that come with the axial piston unit, the required
tightening torques for the threaded plugs M
V
apply. For values, see Table 16.
• 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.

1)
The tightening torques of the threaded plugs M
V
apply to the unit when "dry" and to the plugs when "lightly oiled" for installation.
2)
When "lightly oiled", M
V
is reduced to 10Nm for M10 x 1 and 17Nm for M12 x 1.5. When the unit is "dry" and M
V
reduced, 10Nm for
M10x1 and 17Nm for M12x1.5, the maximum permissible pressure is 420bar.
To connect theaxial piston unit tothe hydraulic system:
1. Remove theprotective plugs and/or threaded plugs from theports where
theconnections should bemade according tothe hydraulic circuit diagram.
2. Make sure thesealing surfaces ofthehydraulic ports and functional surfaces are
not damaged.
3. Use only clean hydraulic lines orflush them before installation.
(Observechapter8.1.6 "Performing flushing cycle" onpage51 when you flush
out theentire system.)
4. If using an external bearing flushing, screw the throttle screw in port"U" in to
thestop.
5. Connect thelines inaccordance with theinstallation drawing and themachine
orsystem circuit diagram. Check that all ports are connected orplugged with
threaded plugs.
