The new speed controller updates include dimensional changes and some electronic component changes. The new actuator updates include some electronic component changes. Refer to Table 1 for a list of the new part numbers.

The new parts are adaptable back to first production on the serial numbers listed above.

Note: Installing a 460-2080 Governor Control As (Speed Controller) is required when installing either the 460-2082 Actuator or the 460-2083 Throttle Gp .

Note: The 460-2080 Governor Control As (Speed Controller) can be used with either the 125-0547 Actuator or the 201-0859 Actuator .

For terminal locations for the 460-2080 Governor Control As (Speed Controller) refer to Illustration 1.
