Maintenance

5.1

General notes on maintenance

l

Do not let the hose stir up the slurry at the bottom of the drum.

l

Do not draw off fuel from near the bottom of the drum.

l

The rest in the drum is not suitable for the engine and should only be used for cleaning purposes.

When performing maintenance work always comply with the appropriate safety regulations.

Thorough maintenance of the machine guarantees higher functional safety of the unit and prolongs the lifetime of important components. The effort needed for this work is only little compared with the problems that may arise when not observing this rule.

The terms right/left correspond with travel direction forward.

Notes on the engine performance On diesel engines both combustion air quantity and fuel injection quantity are thoroughly adapted to each other and determine power, temperature level and exhaust gas quality of the engine.

l

Always clean machine and engine thoroughly before starting maintenance work.

If you engine has to work permanently in "thin air" (at higher altitudes) and under full load, you should consult the customer service of BOMAG or the customer service of the engine manufacturer.

l

For maintenance work stand the machine on level ground.

Notes on the hydraulic system

l

Perform maintenance work generally with the engine stopped.

l

Relieve hydraulic pressures before working on hydraulic lines.

l

Before working on electric parts of the machine disconnect the battery and cover it with insulation material.

l

When working in the area of the articulated joint attach the articulation lock (transport lock).

During maintenance work on the hydraulic system cleanliness is of major importance. Make sure that no dirt or other contaminating substances can enter into the system. Small particles can produce flutes in valves, cause pumps to seize, clog nozzles and pilot bores, thereby making expensive repairs inevitable. l

If, during the daily inspection of the oil level, the hydraulic oil level is found to have dropped, check all lines, hoses and components for leaks.

l

Seal external leaks immediately. If necessary inform the responsible customer service.

l

Do not store drums with hydraulic oil outdoors, or at least under cover. Water can be drawn in through the bunghole when the weather changes.

l

Keep fuel free of contaminants and water, since this will damage the injection elements of the engine.

Always use the filling and filtering unit (BOMAG part-no. 007 610 01) to fill the hydraulic system. This unit is fitted with a fine filter to clean the hydraulic oil, thereby prolonging the lifetime of the filter.

l

Drums with inside zinc lining are not suitable to store fuel.

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

l

Do not leave the tank opening unnecessarily open, but cover it so that nothing can fall in.

Environment During maintenance work catch all oils and fuels and do not let them seep into the ground or into the sewage system. Dispose of oils and fuels environmentally.

Notes on the fuel system The lifetime of the diesel engine depends to a great extent on the cleanliness of the fuel. l

l

l

In order to assure perfect cold starting it is import to chose the viscosity (SAE-class) of the engine oil according to the ambient temperature.

For winter operation below -10 °C the oil change intervals must be shortened.

Regular lubrication oil changes The longest permissible time a lubrication oil should remain in an engine is 1 year. If the following oil change intervals are not reached over a period of 1 year, the oil change should be performed at least once per year, irrespective of the operating hours reached.

Oil quality You should preferably use oils of ACEA quality class E2-96, E3-96/E5-02, E4-99.

Oils of API-quality class CF/CF-4, CG-4/CH-4 may also be used.

Lubrication oil change intervals Oil change intervals with oil quality ACEA: E296, E3-96/ E5-02, E499 = 1000 operating hours API: CF/ CF-4, CG4/CH-4 = 1000 operating hours Caution These intervals apply only when using a diesel fuel with maximum 0.5 % sulphur by weight and for ambient temperatures higher than -10 °C. !

Fig. 63

Lubrication oil with a too high viscosity index causes starting difficulties. The temperature when starting the engine is therefore of highest importance when choosing the viscosity of engine oil for winter operation.

Oil viscosity Since lubrication oil changes its viscosity with the temperature, the ambient temperature at the operating location of the engine is of utmost importance when choosing the viscosity class (SAEclass) (see diagram).

When using fuels with a sulphur content of more than 0.5% to 1% or under ambient temperatures below -10 °C the oil change intervals specified in the table must be halved. When using fuels with a sulphur content higher than 1% ... 1,5% the engine oil must have a TBN of approx. 12 x the S-content in % by weight if the service intervals are halved.

Occasional falling short of the temperature limit (e.g. use of SAE 15W/40 down to -15 °C) may ef-

type HV according to ISO 6743/3. The viscosity index (VI) must be at least 150. (Observe the information of the manufacturer).

Example aspirating engine: Use in tropical climate, fuel 0.8% sulphur, lubrication oil change every 250 operating hours.

l

Bio-degradable hydraulic oil

Lubrication oil quality classes

On request the hydraulic system can also be filled with ester based biodegradable hydraulic oil (Panolin HLP Synth. 46).

The ACEA- and the API-classifications are used to classify the oil quality.

The oil manufacturer is solely responsible for assigning a product to a certain quality class.

The biologically degradable hydraulic oil meets all demands of a mineral oil based hydraulic oil according to DIN 51524.

i Note

In hydraulic systems filled with Panolin HLP Synth.

46 always use the same oil to top up.

When changing to a higher alloyed oil quality after a longer period of operation, it is recommended to perform the first oil change of the higher quality oil already after 20 operating hours. The lubrication oil filter cartridge must be changed at the same time.

When changing from mineral oil based hydraulic oil to an ester based biologically degradable oil, you should consult the lubrication oil service of the oil manufacturer for details.

Check the filter more frequently after this change.

Fuels

Lubrication grease

Quality

For lubrication use only EP-high pressure grease, lithium saponified (penetration 2).

You should only use commercially available brand diesel fuel with a sulphur content below 0.5% and ensure strict cleanliness when filling in. A higher sulphur content has a negative effect on the oil change intervals. Use only winter-grade diesel fuel under low ambient temperatures. The fuel level should always be topped up in due time so that the fuel tank is never run dry, as otherwise filter and injection lines need to be bled.

The following fuel specifications are permitted: DIN 51601; Nato Codes: F-54, F-75; BS 2869: A1 and A2; ASTM D 975-78: 1-D and 2-D; VV-F-800 a: DF-A, DF-1 and DF-2.

Winter fuel For winter operation use only winter diesel fuel, to avoid clogging because of paraffin separation. At very low temperatures disturbing paraffin separation can also be expected when using winter diesel fuel.

Mineral oil based hydraulic oil The hydraulic system is operated with hydraulic oil HV 46 (ISO) with a kinematic viscosity of 46 mm2/s at 40 °C. For topping up or for oil changes use only high-quality hydraulic oil, type HVLP according to DIN 51524, part 3, or hydraulic oils

5.32 Water sprinkler system, maintenance in the event of frost

5.33 Engine conservation If the engine is to be shut down for a longer period of time (e.g. over winter), we recommend the following engine conservation measures to avoid corrosion:

Caution If there is a risk of frost the water sprinkler system must be emptied or filled with an antifreeze mixture. !

l

l

Clean engine and cooling system: With cold cleansing agent and water jet or, even better, with steam cleaning equipment.

l

Run the engine warm and shut it down.

l

Drain the still warm engine oil and fill in anticorrosion engine oil.

l

Drain the fuel from the fuel tank, mix it well with 10% anti-corrosion oil and fill it back in. Instead of mixing the fuel with anti-corrosion oil you may also fill the tank with injection pump testing oil with anti-corrosive properties (e.g.

Calibration fluid B).

l

Then run the engine for 10 minutes, so that lines, filter, pump and nozzles are filled with the conserving mixture and the new engine oil is distributed to all parts.

l

After running the engine take the cylinder head cover off, spray the rocker chambers with a mixture of diesel fuel and 10% anti-corrosion oil. Then fasten the cover again.

l

Crank the engine several times without ignition in order to spray all combustion chambers.

l

Take the V-belt off and spray the grooves of the V-belt pulley with anti-corrosion oil. Remove the anti-corrosion oil before taking the machine back into service.

l

Close air intake on air filter and exhaust opening tightly.

Clean the water tank.

Fig. 100 l

Open drain tap 1 (Fig. 100) and drain off all water.

Position "0"

= Drain tap closed

Position "I"

= Drain tap open.

l

Switch the sprinkler system on and drain all water from the piping.

l

Fill the water tank with approx. 5 l of an antifreeze mixture (water and anti-freeze agent, e.g. glysantene).

l

Switch the sprinkler system on, until antifreeze mixture comes running out of the sprinkler tubes.

i Note Depending on weather conditions these conservation measures will protect the machine for approx.

6 to 12 months.

Before taking the machine back into service you must drain off the conservation oil and replace it with engine oil (see table of fuels and lubricants) according to API-(MIL-) classification.

As required

Anti-corrosion oils are all oils complying with the specification MIL-L-21260 B or TL 9150037/2 or Nato Code C640/642. !

5.34 Tightening torques for screws with metric unified thread

Caution

A machine with conserved engine must be clearly marked by attaching a clear warning label.

Fig. 101

* Strength classes for screws with untreated, nonlubricated surface. Screw quality designations are stamped on the screw heads.

8.8 = 8G 10.9 = 10K 12.9 = 12K The values result in a 90% utilization of the screw's yield point at a coefficient of friction µ total = 0,14.

Compliance with the tightening torque is checked with torque wrenches.

The specified tightening torques do not apply when using MoS2 lubricants.

i Note Self-locking nuts must always be replaced once they have been unscrewed.
