BACKHOE VALVE

The implement and steering pump on the 416E/422E/428E machines is a similar design and operates the same as the pump on the "A" Series machines. The pump is located below the cab floor plate. The pump control valve is mounted on top of the pump and contains a flow compensator spool and pressure cutoff spool. The implement and steering pump supplies oil flow to the loader valve group, backhoe valve group, and steering system.

Travelat high speeds over rough terrain causes bucket movement. The optional Ride ControlSys tem acts as a shock absorber by absorbing bucket forces, which stabilize the machine. The Ride ControlSystem components include; ride controlrelay (A), ride control solenoids (B), ride control accumulator (C), and ride control pressure switch (D). Two solenoids are now used on the "E" Series machines Ride Control System.
