installation instructions:
1.The actuator must be rigidly mounted as close as possible to the engine throttle lever. When selecting the mounting location, consideration must be given to possible linkage obstructions
2.The linkage should be direct, short, and as light as possible. Low friction rod end bearings should be used throughout the linkage system.
3.The linkage should be adjusted so that the fuel control minimum fuel and maximum fuel stops are used rather than the internal actuator stops
4. A Drill the actuator mounting holes in a pre-fabricated mounting bracket. Mounting hole configuration is illustrated in Diagram 4
The position of the actuator on the mounting bracket should insure minimal misalignment between each end of the govemor system linkage. The linkage ball bearing rod ends can tolerate a maximum misalignment of 10 degrees
B Affix the actuator bracket to the selected location on engine.
C Attach the actuator securely to the mounting bracket
D Adjust and secure the linkage rod and rod end bearings.
For proportional actuators to operate with linear control system sit is important to obtain a linear relationship between actuator stroke and fuel delivery
