Troubleshooting 185

Next step is to remove the dump valve all together and verify operation. If the arm operates with the

correct cycle times and pressures, then we can conclude that the dump valve is faulty and needs to be

replaced.
However, should the arm continue to have slow cycle times and low pressures, then the fault more

than likely is with the pump.

To bypass the arm pump dump valve on a front-mounted pump, apply this procedure:

The truck should be off and locked out/tagged out following all required procedures.

Relieve the air pressure from the hydraulic tank.

Close the ball valve (or shut-off valve) on the suction line that is behind the hydraulic tank.

Figure 8

6 Ball valve

Unplug the arm pump dump valve electrical connector and stow the harness safely out of the

way.

Remove the recirculation hose from the arm dump valve to the body pump and cap off the port at

the body pump.
