Tightening torques
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
female threads and should not be exceeded. For values, see Table 12.
• Threaded plugs:
For the metallic threaded plugs supplied with the axial piston unit, the required
tightening torques of threaded plugs M
• Mounting bolts:
For mounting bolts with metric ISO threads as defined in DIN 13 or threads defined
in ASME B1.1, we recommend checking the tightening torque on a case-by-case
basis in accordance with VDI 2230.
When connecting and tightening the connection line to the pilot pressure
port X, the adapter (1) must be secured with a tightening torque of 20 Nm
(WAF 19). The maximum permissible tightening torque of 45 Nm in the female
thread of the adapter (M14 x 1.5, 12 deep) must not be exceeded.
If the adapter (1) is unscrewed from the pilot pressure port X and then screwed
back in again, it must be tightened with a tightening torque of 23 + 2.5 Nm.
For the version without adapter, the pilot pressure port X has an ISO 11926
thread of size 7/16-20 UNF-2B; 11.5 deep.
