What you are ordering
Price is per EFC actuator. All part numbers are separate variants, please select the correct PN from variant options. These EFC actuators are not interchangeable. Different part numbers have different voltage rating, stroke and control parameters. Wrong selection will cause unstable generator frequency, poor load response, speed fluctuation and failure of electronic governing system.

Specifications
Structure: electronic fuel control actuator
Coil & internal component: calibrated to OEM standard
Electrical characteristic: matched for generator governor system
Finish: wear-resistant & anti-corrosion treatment, electrical function tested before packing
Packing: individual protective box, marked with part number

When to replace
EFC actuator suffers coil aging, internal mechanical wear and signal drift after long running hours. Common failure signs: generator frequency drifting, unstable speed, slow response under load, governor alarm. Replace the matched EFC actuator together when abnormal performance appears, and inspect the governor controller and wiring harness at the same time.

Fitting notes
Strictly confirm voltage specification and wiring definition before assembly. Do not install EFC actuators of different part numbers interchangeably. Follow Cummins and Woodward service manual for installation and governor calibration. If you are not sure which PN matches your engine CPL, send us engine serial number for confirmation.
