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.
To connect the axial piston unit to the hydraulic system:
1. Remove the protective plugs and threaded plugs at the ports at which the
connections are to be made according to the hydraulic circuit diagram.
2. Make sure that 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7.5 “Performing flushing cycle” on page47 when you flush out the
entire system.)
4. Connect the lines in accordance with the installation drawing and the machine or
system circuit diagram. Check whether all ports are connected or plugged with
threaded plugs.
5. Tighten the fittings correctly (note tightening torques). Mark all correctly
tightened fittings, e.g., with a permanent marker.
6. Check all pipes and hose lines and every combination of connecting pieces,
couplings or connecting points with hoses or pipes to ensure they are in
condition for safe working.
For relationship between direction of rotation and flow direction, please refer to
data sheet 92003.
