See Graphic: wc_gr002280
Removal:
7.5.1 Turn ignition key to the “OFF” position.
7.5.2 Flip seat assembly forward. Make sure seat lock engages.
7.5.3 Disconnect actuator motor wiring harness (e) and load pin wiring
connector (b).
7.5.4 Remove lower actuator mounting bolt or pin (f).
7.5.5 Remove the load pin retaining snap ring (c).
7.5.6 Support the actuator motor and carefully remove the load pin (d).
Remove the actuator from the mount.
Installation:
Note: Actuator length should be checked every time the actuator is
removed from the machine.
7.5.7 If actuator was removed, adjust actuator length before installation.
Loosen locknut (g) and rotate barrel (h) clockwise until it stops
retracting.
7.5.8 Rotate barrel (h) counter-clockwise to achieve dimension shown in
graphic.
7.5.9 Align actuator motor mounting hole and carefully insert the load pin (d).
7.5.10 Rotate load pin (d) so the smaller alignment flat engages the locking
plate (k).
7.5.11 Install load pin retaining snap ring (c). Make sure the snap ring is fully
engaged into the shaft groove. Check load pin for movement. It should
NOT move in or out.
7.5.12 With the blades pitched flat and the trowel flat on ground, screw rod
end (i) in or out to align hole with mounting hole in gearbox pivot rod.
Hold barrel (h) so it does not rotate while adjusting rod end.
7.5.13 Apply medium strength thread-lock to mounting screw (f) and reinstall
through rod end (i). Torque to 77 ± 8 Nm (57 ± 6 ft.lbs.).
7.5.14 Apply medium strength thread-lock to the threads above the locknut
(g) on the rod end (i). Using band clamp or slip joint pliers around the
barrel (h), tighten locknut to 41 ± 7 Nm (30 ± 5 ft.lbs.).
7.5.15 Connect load pin connector (b) and actuator motor connector (e).
Reinstall any wiring fasteners removed.
