DISASSEMBLING
The disassembly procedure below starts on the premise that the hydraulic lines and the line securing bands have been removed.
WARNING
Arm cylinder weight: 86 kg (189 lb).
Lift and securely place the cylinder on a workbench using a crane. Be sure that the cylinder is placed horizontally. Drain hydraulic oil from the cylinder.
Fully extend the cylinder rod (1). Secure the rod end using a crane. Remove the screws (7) from the cylinder head (4).
NOTE: be sure to pull out the cylinder rod (1) straight so as not to damage the sliding surfaces.
Pull out the cylinder head (4) from cylinder liner (2) by tapping with a plastic hammer. Remove the cylinder rod (1) and the cylinder head (4).
