Installation of rod end fitting elements
To install a fitting element on the rod end threaded bore (BA), use a wrench on the rod end (for ILA
15-25) or fix the push rod with a clamp (for ILA 50-100-150-200) to counterhold the locking torque.
In case of actuator equipped with AR (anti-rotation) device: DO NOT TRANSFER ANY TORQUE TO
THE PISTON ROD.
WARNING: in case of torque transfer into the actuator with AR device, the internal mechanical
components can be damaged.
Fix the threaded element with Loctite 270.
To unmount the element, heat the threaded area to unlock it.
Unscrew the fitting element counterholding the torque on the push rod.
