Ride Control System.
a.
Ride control system provides means for absorbing forces from lift cylinders while machine is traveling. These
forces cause machine to pitch when machine is moving over rough terrain. Main components of ride control sys-
tem are accumulator, ride control valve, and lift cylinders.
427-B1783
b.
Accumulator is mounted to left side of machine. Ride control valve is mounted on left side of machine.
c.
Ride control switch is mounted on control panel in operator compartment.
d.
When ride control system is activated and machine travels over rough terrain with a loaded implement, forces of
load act against lift cylinders. When load acts against head end of lift cylinders, oil from head end will try to flow
into accumulator.
e.
Accumulator has a cylinder charged with nitrogen which acts as a shock absorber as piston resists oil flow.
Makeup oil for rod end can flow through solenoid valve.
