General notes on maintenance

l

Do not let the suction hose disturb the sludge on the bottom of the drum.

l

Fuel left in the fuel drum is not suitable for the engine and should only be used for cleaning purposes.

When servicing the machine pay careful attention to all applicable safety instructions.

Thorough maintenance of the machine ensures maximum reliability and prolongs the lifetime of important components. The necessary effort can by no means be compared with the faults which may occur when not observing these instructions.

Notes on the engine performance

The terms left/right are always related to travel direction forward.

Combustion air and fuel injection rates of the diesel engine have been carefully adjusted and determine the engine's performance and temperature level as well as the quality of the exhaust gas.

l

Clean machine and engine thoroughly before starting maintenance work.

If your machine has to work permanently in "thin air" (at high altitudes) and with full load you should consult or service department or the service department of the engine manufacturer.

l

For maintenance work park the machine on level ground.

Notes on the hydraulic system

l

Maintenance work must generally be carried out with the engine shut down.

l

Depressurize hydraulic lines before working on them.

l

Disconnect the battery and cover it with insulation material before starting to work on electrical components.

l

Always attach the articulation lock (transport lock) before starting to work in the articulation area of the machine.

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 fuel environmentally.

When servicing the hydraulic system cleanliness if of utmost importance. make sure that no dirt or other contaminating systems can enter the system. Small particles can flute valves, cause pumps to seize and block restrictors and pilot bores, thereby causing costly repairs. l

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

l

Seal leakages immediately. If necessary inform the responsible service department.

l

Always use the filling and filtering unit (BOMAG part-no. 007 610 01) to fill the hydraulic system. This unit is equipped with a fine filter which cleans the hydraulic oil and prolongs the lifetime of the filter.

l

Clean fittings, filler caps and their immediate surrounding area before removing them, so that no dirt can fall in.

l

Do not leave the tank opening unnecessarily open, cover it so that no dirt can fall in.

Store used filters in a special waste container and dispose of environmentally.

Always catch biodegradable oil separately.

Notes on the fuel system The lifetime of the diesel engine is decisively depending on the cleanliness of the fuel. l

Keep the engine free of dirt and water as this could damage the injection elements of the engine.

l

When choosing the storage location for fuel make sure that spilled fuel will not harm the environment.

fect the cold starting ability of the engine, but will not cause any engine damage.

Fuels and lubricants

Temperature related lubrication oil changes can be avoided by using multi-purpose oils. The following oil change intervals apply also when using multi-purpose oils.

Engine oil l

Use winter grade engine oil for winter operation!

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 Preferably use oils of ACEA-classification E3-96/ E5-02. This enables utilization of the longest oil change intervals. Oil of ACEA-classification E2-96 may also when reducing the period between oil changes by 50 percent.

Oils of API-quality class CG-4/CH-4 enable utilization of the longest oil change intervals. Oils of APIquality classes CF/CF-4 may also be used when reducing the period between oil changes by 50 percent.

Lubrication oil change intervals Fig. 105

Oil change intervals with oil quality

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.

ACEA E2-96

= 250 operating hours

API

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.

API CF/CF-4

= 250 operating hours

ACEA E3-96/E5-02

= 500 operating hours

API CG-4/CH-4

= 500 operating hours

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) (Fig. 105).

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

BW 141/151 AD-4/BW 151 AC-4

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. When using fuels with a sulphur content of more than 0.5% to 1% or under ambient tem-

BOMAG

61

Maintenance

peratures below -10 °C the oil change intervals specified in the table must be halved. When using fuels with a sulphur content higher than 1% to 1.5% the engine oil must have a TBN of approx. 12 x the S-content in % by weight when halving the oil change intervals.

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

Lubrication oil quality classes

Bio-degradable hydraulic oil

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

On request the hydraulic system can also be filled with ester based biodegradable hydraulic oil, Panolin HLP Synth. 46. This biologically quickly degradable hydraulic oil Panolin HLP Synth.46 meets all demands of a mineral oil based hydraulic oil according to DIN 51524. In hydraulic systems filled with Panolin HLP Synth. 46 always use the same oil to top up.

i Note 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.

Fuels

Check the filter more frequently after this change.

Quality 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.

Drum drive gear oil For the gearbox use only multi-purpose transmission oil of API-class GL5 with viscosity class SAE 80W-90.

Lubrication grease For lubrication purposes use an EP-high pressure grease, calcium and/or lithium saponified (penetration 2), acc. to DIN 51502 KP 2G.

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.

In most cases a sufficient cold resistance can also be achieved by adding flow enhancing fuel additives. Consult the engine manufacturer.

Dust on the outer diameter of the outlet tube can impair effective sealing. l

l

Check the old main filter element.

The old main filter element can be of help to discover foreign particles on the sealing face, which could lead to leaks. A line of dust on the clean air side of the filter may be a sign for such a leak.

Eliminate this problem before installing a new main filter element. l

Insert the main filter element (Fig. 170).

The radial sealing area is located at the inside of the open filter edge. This critical sealing area must be under slight tension after the filter has been installed. In order to achieve a tight seal apply pressure to the outer edge of the filter and not to the moveable centre. l

5.38 Tightening torques

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

Clean the engine, including the cooling system. With cold cleansing agent, or, even better, with a steam cleaner.

l

Run the engine warm and shut it down.

l

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

l

* Strength classes for screws with untreated and non-lubricated surface. The quality designation of the screws is stamped on the screw heads.

Drain the coolant and fill it back in with fresh anti-freeze agent.

l

Drain the fuel from the fuel tank, mix it well with 10% anti-corrosion oil and fill it in again.

8.8 = 8G

l

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

l

Crank the engine several times by hand (without ignition) in order to spray all combustion chamber.

l

Take the V-belt off and spray the grooves of the V-belt pulleys with anti-corrosion oil. The anti-corrosion oil must be removed before taking the machine back into service.

l

Close the air intake opening on the air filter and the exhaust opening.

10.9 = 10K 12.9 = 12K The values result in a 90% utilization of the screws yielding point at a coefficient of friction of tot. = 0,14. The tightening torques are not valid when using MOS2 lubricants.

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

i Note Depending on the weather condition these conserving measures will provide protection for approx. 6 - 12 months.

The conserving oil must be replaced by engine oil according to the API- (MIL) classification before taking the machine into operation. Refer to the section "Fuels and lubricants".

Anti-corrosion oils are those that comply with the specification MIL-L-21260 B or TL 9150037/2 resp. Nato Code C 640/642.

Mark a machine with conserved engine by attaching a clearly visible warning tag.
