Displacement limiter adjustment
Pump may have a displacement limiter on each side of the servo. Each limiter may be adjusted to a
different setting.
1. Remove snap ring (928) and sleeve (929).
2. Using a flat screw driver to hold the displacement limiter, loosen the locking nut (927) with a 9/16 hex
wrench.
3. Rotate the displacement limiter (911) to adjust maximum displacement. Rotating the adjusting screw
clockwise decreases the maximum displacement of the pump while rotating the adjusting screw
counterclockwise increases the maximum displacement. The displacement changes approximately 4
cm³ per revolution.
4. After establishing the desired maximum displacement setting, hold displacement limiter in place
using a flat screw driver and tighten the locking nut with a 9/16 in. hex wrench. Torque to 19 N•m [14
lbf•ft]. Repeat if necessary to adjust maximum displacement in other direction.
