D5R Track-Type Tractor Ripper Does Not Function
1.1. Probable Causes
2.1. Recommended Actions
3.2. Restrictions In Oil Lines
4.2. Leaks At Fittings And Connections Of Hydraulic Lines or Hoses
5.2. Blockage of The Main Suction Hose

Probable Causes

  • Restrictions in oil lines

  • Leaks at fittings and connections of hydraulic lines or hoses

  • Blockage of the main suction hose

Recommended Actions

ReferenceRefer to Testing and Adjusting, KENR8558.

Check the monitoring system for any fault codes that are related to the ripper lever "raise/lower" position sensor.

Restrictions In Oil Lines

Blockages, kinks, or restrictions in oil lines in both the supply and return oil lines can prevent oil flow to hydraulic components. Components cannot operate without oil flow from the pump. Components cannot operate properly with reduced flow or pressure available to motors, cylinders, actuators, and so on.

Check for restrictions on all hydraulic oil hoses, lines, and tubes in the system or the circuit in question. Correct any problems that are found then retest the hydraulic system for any symptoms.

Leaks At Fittings And Connections Of Hydraulic Lines or Hoses

Leaks at fittings and other types of hydraulic line connections can cause loss of oil flow and prevent components from attaining necessary pressures. Pressure losses may generate complaints of weak lift force. Leaks at fittings and connections on the pressure side of pumps are a direct source of oil loss in the system, which can lead to component failure if the low oil levels are not monitored and pumps and motors are starved of oil. Leaks at fittings and connections on the suction side of pumps are a direct source of oil aeration, which can also damage to components (cavitation) and create excess or unusual noise.

Check for leaks at all fittings and connections of hydraulic oil hoses, lines, and tubes in the system in question. Correct any problems that are found then retest the hydraulic system for any symptoms.

Blockage of The Main Suction Hose

Blockages or restrictions in the main suction oil line will stop the supply of hydraulic oil flow to the pumps. Components cannot operate without oil flow from the pump. Components cannot operate properly with reduced flow or pressure available to motors, cylinders, actuators, and so on, Correct any problems that are found then retest the hydraulic system for any symptoms.
