Wacker Neuson 8003 Track Excavator Maintenance Manual

Operational readiness and the service life of machines are heavily dependent on maintenance. It is therefore in the interest of the machine owner to perform the prescribed maintenance work.

Bear in mind the following points before performing service and maintenance work:

• Chapter 2 Safety instructions of this Operator’s Manual.
• The Operator’s Manuals of the attachments.

Perform the prescribed inspections and rectify any disorders immediately before putting the machine into operation, or have them rectified by an authorized service center. Secure the open engine cover and other open covers appropriately. Do not open the engine cover and other covers on slopes or in strong wind. When using compressed air, dirt and debris can be blown into your face. Therefore, wear protective goggles, masks and clothing when using compressed air.

Service and maintenance work must be performed by a specifically trained person. All other maintenance work that is not indicated in this Operator’s Manual must be performed only by the trained and qualified staff of a Wacker Neuson service center.

The following maintenance plans indicate the maintenance work to be performed. This is necessary to ensure optimal functioning – see chapter 5.22 Maintenance plan (overview) on page 5-57. Immediately repair or replace parts that are already damaged or not working properly before they are due for replacement.

Fuel-filling pump (option) (75Z3 from serial no. AH00646; 8003 from serial no. AH00611)

1. Park the machine on firm and level ground.
2. Stop the engine.
3. Turn the starting key fully to the left to park position P.
4. Fold the control lever base up.
5. Open the engine cover.
6. Insert hose C of fuel-filling pump A into the container with the fuel – see Stationary fuel pumps on page 5-4.
7. Press button B to switch on fuel-filling pump A.
8. Then switch off fuel-filling pump A with button B.
9. Put hose C back in the bracket

Wacker Neuson 8003 Engine and hydraulics cooling system
The oil/water radiator is located in the engine compartment, on the right side of the engine. It cools the diesel engine, and the hydraulic oil of the drive and work hydraulics. The expansion tank for the coolant is also located in the engine compartment, in front of and above the cooler.

How the diesel particulate filter works
The machine is equipped with a closed diesel particulate filter with passive regeneration, active diesel fuel injection and a catalytic converter installed before the filter.

Wacker Neuson 8003 Track Excavator Passive regeneration
The special coating of the diesel particulate filter lowers the ignition temperature of the diesel soot and ensures that the soot burns on its own including at low exhaust gas temperatures. Consequently, the soot particles retained by the diesel particulate filter are continuously burnt.

Wacker Neuson 8003 Track Excavator Active diesel fuel injection
If output requirements are low, the exhaust gas temperatures of the diesel engine are too low to ensure passive regeneration. The soot particles cannot be burnt and form deposits in the filter. If a certain pressure threshold is crossed and the temperature is briefly higher, the controls activate diesel fuel injection for a short time. This causes the temperatures in the filter to rise and makes regeneration possible.

Wacker Neuson 8003 Track Excavator Catalytic converter
In addition to sufficiently high temperature, soot regeneration also requires enough NOx. However, the exhaust gas of the new environment friendly diesel engines does not always contain enough NOx under all operating conditions. Therefore, a catalytic converter is installed before the filter to avoid any such shortcomings.

Wacker Neuson 8003 Track Excavator Control box
The control box monitors and saves the temperature and the pressure in the particulate filter system, transmits the data to the display and controls diesel fuel injection.

Condensate trap
The condensate trap protects the control box against damage caused by water by eliminating the condensation water in the pressure line.

Injection nozzle
The injection nozzle is controlled by the control box and if required, injects diesel fuel into the exhaust pipe in front of the particulate filter.
