7.28 Removal and Installation of Actuators
See Graphic: wc_gr003446
Removal:
7.28.1 Turn off the machine.
7.28.2 Remove lower actuator mounting bolt or pin (a).
7.28.3 Remove the load pin (b) and carefully remove the actuator (c) from the
machine. See section Removal and Replacement of Actuator Load
Pins.
Installation:
The actuator length should be checked every time the actuator is
removed from the machine. Adjust the actuator length before
installation. To adjust the actuator length:
7.28.4 Loosen the locknut (d) and rotate the barrel (e) clockwise until it stops
retracting.
7.28.5 Rotate the barrel counterclockwise to achieve the dimension shown.
7.28.6 Install the load pin (b). See section Removal and Replacement of
Actuator Load Pins.
7.28.7 With the blades pitched flat and the trowel flat on the ground, screw the
rod end (f) in or out (while holding the barrel (e) so it does not rotate)
so that the rod end aligns with the mounting hole in the gearbox pivot
rod.
7.28.8 Apply Loctite 243 or an equivalent to the mounting screw (a) and
reinstall it through the rod end and into the gearbox pivot rod. Torque
the mounting screw to 77 ± 8 Nm (57 ± 6 ft.lbs.).
7.28.9 Apply Loctite 243 or an equivalent to the threads (g) above the locknut
(d) on the rod end. Using a band clamp or slip joint pliers to hold the
barrel, tighten the locknut to 41 ± 7 Nm (30 ± 5 ft.lbs.).
7.28.10 Turn the key switch to the ON position and test the actuator function(s).
