Arms Down Deceleration Valve
The arms down deceleration valve (see Figure 3-49) automatically decelerates the arms as they are
lowered. A cam bolted to the arm pivot tube rotates as the arms are lowered and gradually depresses
the valve spool, reducing the flow of oil exiting the shaft end of the arm cylinders.
N
OTE
:
The deceleration valve greatly reduces impact on the arm assembly, body structure, and
hydraulic components.
Location: Fitted to the underside of the body, behind the arm pivot tube on the streetside.
For adjustment procedure, refer to “Adjusting the Arms Down Deceleration Valve” on page 108.
