Two different types of step nose lighting units have been installed during manufacturing. ï· The early units (which are limited available as spare part) are provided with a LED card for the âdownwardâ light and an optical fiber for the âupwardâ light. These units have a small circuit board with a resistor to reduce the 24V power supply to an operating voltage of 3V for the optical fiber (refer also to figure 1). ï· The new units have an optical fiber for both the âdownwardâ and âupwardâ light, and do not have a circuit board to reduce the voltage supply. These lighting units may not be connected directly to a 24V power supply but must be used together with special controllers. Failure to do will cause the immediate irreversible breakdown of the lighting unit due to overvoltage! Please also note that the âdownwardâ light on new units is less bright. This service bulletin provides you with information on how the new step nose lighting units are connected to the vehicle wiring.

Van Hool has determined that the parcel-rack lighting circuit is not well executed due to an error in the production process. On TD925 vehicles, a connection in the parcel-rack lighting circuit is inadequate. The splicing of the electrical wires has been executed by twisting the strands together and insulating them with electrical tape instead of using a connector. Also neighbouring spare wires were mistakenly put together in the same connection. This situation can result in arching and overheating when the parcel-rack lighting circuit is energized and one of the spare wire ends is grounded. Follow the step-by-step instructions mentioned under "To modify TD925 parcel-rack lighting c ircuit". The necessary parts are listed in the table on page 2. On TDX25US vehicles, a 4-pin connector with loose wires has not been removed as it should have been. This may result in arching and overheating when the parcel-rack lighting circuit is energized and one of the loose wire ends is grounded. Follow the instructions mentioned under ?To modify TDX25 parcel-rack lighting circuit?. No parts are necessary for TDX25 vehicles.

Service Information: Bevel gear of front axle steering system Service records have shown that the grease in the bevel gear could affect performance at very low temperatures (below -20°C/-4°F). If the grease in the bevel gear becomes hard enough to affect drivability, additional manual force could be required to turn the steering wheel. This would be especially noticeable when the steering wheel is turned the first times after an initial start-up. The phenomenon could disappear later as a matter of course due to the warming up of the grease in the bevel gear. Additionally it has been determined that in some cases water has penetrated the bevel gear via the sealing thereby contaminating the grease. The penetrating water will start corrosion of the bearings. This problem shows a gradual, but continual increase of the steering forces and will not disappear at higher ambient temperatures or when the bevel gear is in use. Checking the bevel gear rotation torque will help in determining if the bevel gear needs to be replaced. If either of these conditions are observed, it is necessary to replace the bevel gear by the corresponding ZF bevel gear. Old and new bevel gears are interchangeable, but note that two different types of bevel gears are used. Also note that the new bevel gear has a mid-position which should be taken into account during the installation of the bevel gear.
SB1279
Field Change Program: To check propeller shaft for interference It has been reported that the propeller shaft can interfere with the body structure in off-road circumstances (for example when driving on a vessel for overseas transportation).

Field Change Program: To replace pivot bearing of hydraulic steering cylinder and greasing recommendations Van Hool is informed about seizing of the hydraulic cylinder pivot bearing of the trailing axle steering. To address this issue, the customers of the affected vehicles must replace the pivot bearing of the hydraulic cylinder by a new one, remove the factory installed plug and install a grease nipple for routine greasing. Starting with VIN42767 Van Hool has factory equipped the hydraulic cylinder with a grease nipple for routine greasing. The pivot bearing of the hydraulic cylinder should be lubricated every 12 500 miles. To address this issue, Van Hool is conducting a field change program.
