4.1.2 Actuator Installation
Remove the Actuator Assembly (69170) from the Retrofit Kit and install as follows:
1. Depress and hold the Clutch Button (Figure 4-4) and rotate the pointer to approximately
80° on the dial. Release the Clutch Button when properly positioned.
CAUTION
DO NOT DEPRESS THE YELLOW CLUTCH BUTTON WITH POWER
APPLIED TO THE ACTUATOR. Doing so will damage the actuator
mechanism
2. Slide the Actuator onto the Linkage Assembly Shaft (Figures 4-2 & 4-4). Ensure that the
pin on the Linkage Assembly is inserted in the center slot on the bottom of the Actuator
(Figure 4-4).
3. Press down on the Linkage Adapter and verify that the Indicator Plate is aligned with the
“0” Scale marking.
4. With the Indicator Plate properly aligned, tighten the U-bolt hex nuts using an 8 mm
wrench. Torque the nuts to 60 in-lbs.
5. This completes the mechanical installation of the Actuator Assembly. The electrical
connections will be made during installation of the Control Box in paragraph 4.7.
