General repair instructions

Before removing or disassembling and parts, hoses or components mark these parts for easier assembly. Before assembly oil or grease all parts, as far as this is necessary.

●

Fill new hydraulic units with hydraulic oil before starting operation.

●

After changing a component thoroughly flush and bleed the entire hydraulic system.

●

Perform measurements at operating temperature of the hydraulic oil (approx. 40 °C).

●

After changing a component perform a high and charge pressure test, if necessary check the speed of the exciter shaft.

●

The operating pressure of the exciter shaft to a great extent depends on the base under the vibrating drum. If the soil is too hard place the drums on old rubber tires. Do not activate the vibration on a hard, concreted base, danger of bearing damage.

●

After the completion of all tests perform a test run and then check all connections and fittings for leaks with the engine still stopped and the hydraulic system depressurized.

Hydraulic system Caution Do not open any hydraulic components if you have not been properly trained and without exact knowledge.

Please note Cleanliness is of utmost importance. Make sure that no dirt or other contaminating substances can enter into the system. ●

Clean fittings, filler covers and the area around such parts before disassembly to avoid entering of dirt.

●

Before disconnecting hoses, pipes or similar relieve the system pressure with the engine shut down.

●

During repair work keep all openings closed with clean plastic plugs and caps.

●

Do not run pumps and motors without oil.

●

When cleaning hydraulic components take care not to damage any fine machine surfaces.

●

Chemical and rubber soluble cleansing agents may only be used to clean metal parts. Do not use such substances to clean seals and gaskets.

●

●

●

After changing a component clean the hydraulic oil tank thoroughly.

●

Fill the housings of hydraulic pumps and motors with hydraulic oil.

●

Use only hydraulic oils according to the specification in the maintenance instructions.

●

After changing a component clean the hydraulic system as described in the flushing instructions in order to prevent all other components from being damaged by abrasion and metal chips remaining in the system.

Rinse of cleaned parts thoroughly, dry them with compressed air and apply anti-corrosion oil immediately. Do not install parts that show traces of corrosion.

●

Change the hydraulic oil filter.

●

Bleed the hydraulic circuits.

Avoid the formation of rust on fine machined caused by hand sweat.

●

Start up the system without load.

●

Check the hydraulic oil level in the tank, fill up oil if necessary.

●

Grease must not used as a sliding agent for assembly work. Use hydraulic oil.

●

Do not start the engine after the hydraulic oil has been drained off.

●

●

Before commissioning

Use only the specified pressure gauges. Risk of damaging the pressure gauges under too high pressure. Clean ports and fittings before removal so that no dirt can enter into the hydraulic system.

●

Check the hydraulic oil level before and after the work.

●

Use only clean oil according to specification.

●

Check the hydraulic system for leaks, find and rectify the cause.

008 912 53

Commissioning

After commissioning ●

Check system pressures and speeds.

●

Check fittings and flanges for leaks.

●

After each repair check all adjustment data, rotational speeds and nominal values in the hydraulic system, adjust if necessary.

●

Do not adjust pressure relief valves and control valves to values above their specified values.

Electrical system ●

Always disconnect the battery before starting work in the electrical system.

●

Ensure correct polarity when connecting the battery.

2.17 Automatic detection of step currents for the steering valves For a sensitive and exact control of the steering the step currents must be determined for the four control solenoids of both steering valves. The step currents are automatically adjusted after entering the code number, so that no additional meter is required. After entering the respective code number the current is increased by the control solenoid in 5 mA steps. After each current increase the system waits for two seconds. If the ESX-control has detected a considerable angle change of the drum after the expiration of the waiting time, the step current is reached. In order to enhance the measuring result the measurement is performed three times. The final step current is the mean value of the three measurements. This step current is automatically stored and is valid from the next time the machine is started.

L Note The determination of the step currents is only required during initial start-up in the factory, after replacing a steering valve, the steering valve control or after changing the ESX-control The measurement is identical for all solenoids. Caution For the determination of the step current park the machine ón firm and level ground.

The steering system must be thoroughly bled before performing this measurement. Align the drum to straight ahead position. The new values will only become active after the ignition has been switched off and on again. Danger Danger of injury!

Flushing filter installation (Fig. 1)

1. Always flush the closed circuit.

1. Connect the flushing filter outlet "OUT" with the travel pump. 2. Connect the flushing inlet „IN“ with the hose from the front drum drive motor.

Caution Solid particles remaining in the circuit will damage the components again within a short period of time.

Caution The flushing filter must be installed in the low pressure side in the return flow to the pump, so that only cleaned oil will enter the travel pump.

In case of excessive oil contamination (abrasion) 1. Open and clean all other components.

With the connection shown in the illustration the travel pump must therefore be actuated to reverse direction.

2. If necessary replace the hydraulic hoses. 3. Flush also the vibration circuit.

General notes on trouble shooting in hydraulic systems

●

Check the hydraulic oil level before and after the work.

The following tests are performed for fault diagnostics and should enable you to encircle a fault in the hydraulic system.

●

Use only clean oil according to specification.

●

Check the hydraulic system for leaks, find and rectify the cause.

●

Ensure strict cleanliness, clean ports and fittings before disconnecting.

●

Fill new hydraulic units with hydraulic oil before starting operation.

●

After changing a component thoroughly flush and bleed the hydraulic system.

●

AS far as possible conduct all measurements at operating temperature 40 ... 50 °C.

●

After changing a component check charge and high pressure, if necessary check the rotational speed.

4.1

General

At this point it is assumed that there is no fault in the electric system, i.e. trouble shooting in the electric system has already been performed. In some cases these tests may also be conducted to identify faults on hydraulic components of the power transmission system. On the basis of preliminary tests the individual measurements have the purpose to limit the cause of the fault first of all to a general area and then to determine exactly which oil circuit or hydraulic component is not working correctly.

Important points for trouble shooting and fault rectification

Hydraulic hoses Danger Danger of injury

Danger Danger of injury!

Hydraulic hoses must be visually inspected at regular intervals.

Do not touch rotating parts of the engine. When working on the travel pump and performing tests in the travel circuit block the drums with suitable wheel chocks. Hydraulic oil escaping under pressure can penetrate the skin and cause severe injury. You should therefore relieve the pressure in the system before disconnecting any lines. Before repressurizing the system make sure that all line connections and ports are in perfect condition.

Hydraulic hoses must be immediately replaced if: ●

the outer layer is damaged down to the inlay (e.g. chafing, cuts, cracks, etc.)

●

the outer layer is brittle (formation of cracks in the hose material)

●

the hose shows deformations in pressurized and depressurized condition, which do not comply with the genuine shape of the hydraulic hose

●

the hose shows deformations in bends, e.g. squeezing, buckling, layer separation, formation of blisters

●

the hose is leaking

●

the hydraulic hose has separated from the fitting

●

the fitting shows corrosion that impairs both function and strength

●

the fitting is deformed in a way that both function and strength are affected

●

the storage time and utilization period has expired.

When being injured by hydraulic oil consult a physician immediately, as otherwise this may cause severe infections. Caution It is not recommended to open or repair hydraulic units and components without comprehensive knowledge.

Risk of damage to pressure gauges if incorrectly connected. When performing trouble shooting it is assumed that the machine is correctly equipped and connected, that connections and hoses are free of faults and that setscrews have not been deadjusted without permission. Progressive tests drawn up in the trouble shooting diagram lead to the detection of faults and their rectification by trained personnel. ●

Ensure strict cleanliness, clean ports and fittings before disconnecting.

●

Cover all openings and ports or close with plugs.

Bei den Verstellpumpen A4VG erfolgt zur Zeit die Umstellung der Verstellung auf Turcon-Dichtungen. Die Stückliste der kompletten Einheit erhält dabei eine neue Ident.- Nummer. Typenschlüssel, Typnummer und Außenabmeßungen bleiben dabei unverändert. (Pumpengehäuse ändert sich nur im Bereich vom Stellkolben. Stellkolben ändert sich in eine angefaste Ausführung). Alten Stellkolben nicht bei Turcon-Dichtung verwenden (scharfkantig - Dichtungen werden beschädigt). Pumpengehäuse / Pump housing mit Lagerbuchse / with bush ALT / OLD

At present the change of the control into Turcon seal is made for A4VG. The parts list of the complete unit will receive a new identification number. Type reference and outside dimensions remain unchanged (pump housing will change at the area of the positioning piston. Positioning piston will change into chamfering design). Do not use old positioning piston with Turcon seal (sharp edged - seal will be damaged)

Pumpengehäuse / Pump housing mit Turcon-Dichtung / with Turcon seal *

NEU / NEW *

Die Umstellung der Verstellung auf TurconDichtung ist im allgemeinen mit einer Funktionsverbesserung verbunden (DA-Verhalten, geringerer Temperatureinfluß auf Stellzeiten).

The change of the control into Turcon seal design improves in general the function (DA-behaviour, lower temperature-influence on control times).

Bei gleicher Düsenbestückung können sich die Stellzeiten geringfügig verändern.

The control times will slightly change with the same throttle sections. Therefore our customers have to be informed about this change.

Sicherheit und Qualität

Safety and Quality

Vor den Wartungsarbeiten

Before servicing

• Alle notwendigen Sicherheitsvorkehrungen treffen (Menschen und Material) und die geltenden Sicherheitsvorschriften beachten. • Parkbremse betätigen und Maschine mit Keilen festsetzen. • Energieerzeugung (Motor) des Hydrauliksystems abstellen und die Stromversorgung ausschalten. • Gegebenenfalls eine Sicherheitszone einrichten.

• Be extremely careful to prevent personal injury and to avoid damage to material. Comply with all safety regulations.

• Die Außenflächen der Bauteile reinigen, um Schmutz und Fett restlos zu entfernen. • Warten, bis das Hydrauliksystem vollständig abgekühlt und druckentlastet ist (die Speicher entlasten).

• Wash dirt and grease from exterior of the components.

Das heiße oder unter Druck stehende Öl kann zu schweren Verbrennungen mit Entzündung führen. Bei einem Unfall einen Arzt hinzuziehen.

Hot or pressurized hydraulic fluid may cause serious burns & infections to the human body. Consult a physician in case of accident.

!

• Apply the parking brake and prevent the machine from rolling with tire blocks. • Stop the hydraulic system power source (engine) and disconnect the battery. • If necessary, block off the safety area.

• Await the complete cooling down and depressurization of the hydraulic system (accumulators must be purged).

!

Während der Wartungsarbeiten

During servicing

• Bestimmte Bauteile sind sehr schwer. Sie müssen bei der Abnahme vom Rahmen mit einer angemessen ausgelegten Hebevorrichtung gehalten werden. • Die Sauberkeit ist wesentlich beim Betrieb der Hydraulikbauteile. Die meisten Teile können mit einem sauberen Lösungsmittel gereinigt werden. • Während der Handhabung alle empfindlichen Oberflächen gegen Stöße schützen (Zentrierungen, gleitende Teile, Auflagen, Dichtungs- und Lagerauflagen usw.).

• Some hydraulic components are very heavy. Secure them with a lifting device of adequate capacity when removing from the machine frame.

•

•

• Cleanliness is essential to functioning of the hydraulic components. Most of the parts may be cleaned with a clean solvent. • During handling, protect all sensitive surfaces from shocks (piloting and interface surfaces, thrust & bearings surfaces, seal races, etc...)

Diese Flächen vor dem Wiederzusammenbau reinigen. • Systematisch die demontierten Dichtungen beim Wiederzusammenbau durch neue ersetzen. Wir empfehlen, vor der Montage alle Dichtungen zu fetten.

• Always install new O-rings, seals & gaskets discarding the old ones. We recommend lubricating all seals prior to assembly.

• Alle gleitenden Flächen durch Aufbringen eines Films sauberer Hydraulikflüssigkeit ölen, der eine korrekte Schmierung beim ersten Neustart gewährleistet.

• Lubricate all surfaces which have relative motion between parts by coating them with a film of clean hydraulic fluid to assure lubrication at first start.

• Niemals die Hydraulikflüssigkeit, die sich bei hohen Temperaturen entzünden kann, erwärmen. Einige Lösungsmittel sind ebenfalls entzündlich.

• Never heat hydraulic fluid, as it may flame at high temperature. Some solvents are also flammable.

Während der Arbeiten nicht rauchen.

Do not smoke during servicing.

Nach den Wartungsarbeiten

After servicing

Die Bauteile wieder einbauen und das Hydrauliksystem gemäß den Anweisungen in den folgenden Dokumenten wieder in Betrieb nehmen: • INSTALLATION MS D/GB (ref: 800078173V) • INSTALLATION CIRCUITS D/GB (ref. 677777853U)

Reinstall the components and restart the hydraulic system according to instructions defined in the following documents: • INSTALLATION MS F/GB (ref. 677777844K)
