Woodward 8561-882 PSG Governor | Detroit Diesel Engine Compatible

Product Description

The Woodward 8561‑882 PSG Governor is a mechanical-hydraulic governor engineered for precise speed regulation of diesel engines in marine, industrial, and generator applications. Its pressure-sensitive hydraulic mechanism adjusts fuel delivery in response to engine load and speed, maintaining consistent operation across a wide range of conditions.

This governor is compatible with Detroit Diesel engines, including 6V-53, 6V-71, 6V-92, 8V-71, and 8V-92 series. Moreover, its robust cast iron housing and weather-resistant design make it ideal for harsh industrial and marine environments. The PSG governor is widely used where mechanical reliability and simplicity are preferred over electronic control.

The 8561‑882 connects directly to fuel racks or throttle valves, delivering sufficient torque to maintain engine stability under varying load conditions. Its durable construction ensures long-term service life, while periodic mechanical inspection keeps maintenance straightforward and predictable.
