Governor adjustment

N:Pump speed R:Rack position (mm) (1)Beginning of damper spring operation: DL (2)Rack limit (operating at delivery) (3)Excess fuel setting for starting: SXL (4)Set the tamper proof shaft (N = N1).
----------
DL=6-0.5mm SXL=12.4+0.2mm N1=1000r/min

N:Pump speed (r/min) R:Rack position (mm) 1. After governor adjustment, adjust the shaft as described below and stamp the cap. (1)Turn the load lever stopper bolt determining the full rack position (R = Rf) 1~2 turns counterclockwise. (2)Then, increase the full rack position. (3)Operate the pump at N = Nf and turn the shaft (B) clockwise. (4)Adjust so that full rack is Rf+0.4. (5)Tighten nut (A) to the specified torque. (6)Turn the stopper bolt clockwise the same amount that it was turned counter clockwise in (1). (7)Then, align with the full rack position (R = Rf) and fix. (8)Apply thread lock adhesive to the entire circumference of the cap (C) and tap it down to pressfit and seal it.. (9)Check for air tightness.
