The hydraulic governor series NZ/ Model NZ61

► Technical specification of Yanmar NZ61:


(A): for Engine model 6N160 & 6N165

(B): for Engine model 6N18 & 6N21






The body of this governor comprises an oil sump chamber, and thus the governor can use an equivalent to the system oil for the engine as governor hydraulic oil

► Cautions on Handling of the governor:

  • Do not install and handle the governor so that a force is applied to or a shock is imparted to the gear shaft, speed control shaft and terminal shaft
  • When attaching the governor to the engine, attach the governor to its driving device under the governor’s own weight while setting the spline of the gear shaft, and uniformly tighten tightening nuts
