FAULT CODE MANUAL Created on 00-04-25 15:30 1. Bus Instrument Cluster (BIC) The bus instrument cluster contains a number of indicators and lamps that shows the status of different parts of the bus. It can also be used to display faultcodes from the different control units by using the windscreen wiper handle.
FAULT CODE MANUAL Created on 00-04-25 15:30 4. Display menus The image below displays the main menus in the display window. The window can only display three items at once, therefore the up/down button on the windscreen wiper handle must be used to browse through the menus. Simply press the “Return” button on the windscreen wiper handle to enter a desired menu.
FAULT CODE MANUAL Created on 00-04-25 15:30 6. Read fault codes from ECU From the main menu, use the up/down button on the windscreen wiper handle to move down to the “System diagnostic” menu and press the “Return” key. The line “Fault diagnostic” should now be highlighted, if it’s not you can simply use the up/down button on the windscreen wiper handle to move to that line.

Inspection Inspect Safe operation requires thorough examination of wheels and attaching hardware, at frequent intervals, both on and off the vehicle. thoroughly and frequently Wheels that have been in service need to be inspected at regular intervals to assure proper and safe performance. Like tires and other vehicle components that work hard, wheels will eventually wear out.
Excessive WARNING Excessive heat from fire, brake malfunction, wheel bearing heat damage failure or other sources may weaken the metal and cause the wheel/tire assembly to separate explosively. Exploding wheel/tire assembly can cause death or serious injury. WARNING Immediately and permanently remove from service any wheel that has been exposed to excessive heat.
Dimension Open side circumference check checks WARNING Wheels that have been subjected to high pressure tire and rim separation, run flat, excessive heat or other physical damage may no longer have sufficient dimension and contour to retain tire bead while under pressure. WARNING Rims that lack proper dimension and contour can lead to explosive separation of tire and rim, causing injury or death.
Dimension Tire wear or ride problems checks (continued) If you experience tire wear or ride problems it may be helpful to check radial run out. Remove the wheel from the vehicle, deflate and remove the tire (see 3-5, page 22 for recommendations and instructions for demounting tubeless tires and 6-5, page 43 for recommendations and instructions for demounting tube-type tires).
Mounting area Stud hole cracks are usually caused by improper torquing (see 4-9, page 29 and 5-2, page 35), excessive loading or insufficient mounting flange support by the hub or brake drum. Remove wheel from service. Shown below are stud hole cracks emanating from stud hole to stud hole. Causes are: undersized diameter of wheel support surface (see specifications below), support surface not flat, incorrect attachment parts (see 4-12, page 34) and insufficient torque (see 4-9, page 29 and 5-2, page 35).
Mounting area Support surface diameters (continued) Support surface (backup diameter) should be flat to the diameter recommended on the chart below: Number of Bolts Bolt Circle Mounting Type Backup Diameter Thread Size 11.25 inch U.S. Stud pilot 13.2-13.5 in. .750/1.125 in. 285.75mm Hub pilot 13.2-13.4 in.
Stud holes If wheels are run loose, both stud located wheels and hub piloted wheels can be damaged. Look for wallowed out or elongated ball seats on stud located wheels. On hub piloted wheels look for elongated stud holes. Over torquing can lead to damaged ball seats on stud located wheels and can damage the disc surface of hub piloted wheels.
Rim area Check the entire rim area for nicks, gouges and cracks. Loss of air may be caused by cracks in areas around the valve stem hole. Remove the wheel from service. Gutter area Projections on the side of the wheel gutter area on tube type wheels can cause uneven seating of the side and lock ring and chipping of the gutter.

Design and Operation II. Design and operation Design The housing of the ZF Servocom steering gear houses the steering valve, the steering cylinder and a complete manual steering gear. The oil flow and the pressure required by the steering gear is supplied by an engine-driven pump. To achieve this, the oil is taken in from the oil tank and fed back to the tank via the pump and the steering gear.
Page 614
Design and Operation The steering valve consists of the valve rotor (C) which is carried in a needle bearing in the worm and is provided with six control grooves on the circumference, and of the valve sleeve (D) on the worm.

Page 617
Design and Operation Operation of the hydraulic steering limitation The hydraulic steering limitation prevents a steering to the lock stops at full hydraulic pressure. It, thus, protects the pump and the steering linkage and prevents high oil temperatures. A double-acting steering limiting valve with spring-loaded valve pins (T and U) is arranged in the longitudinal direction in the piston (B).
Servicing Work III. Servicing work Hints In a number of countries a safety inspection (Sicherheitsprüfung = SP) is prescribed by law for vehicles with more than 8 passenger seats or a gross vehicle weight rating in excess of 7.5 t. Attention: On vehicles not subject to the safety inspection (SP), the work detailed in Chapter III.

This list represents the currently valid status and is not subject to the Updating Service. 3.5 Steering gear play (part of SP) Start the engine Rotate the steering gear to the straight ahead driving position.
Servicing Work Oil change and bleeding 4.1 Oil change 4.1.1 Draining the oil Note: An oil change is only required if steering gear units were repaired or replaced. Do not use any drained oil to refill the system. Avoid any blending of oils. 4.1.2 Draining the steering system Jack the steered axle up.
Page 625
Servicing Work To achieve a quick draining, open the one among the components referred to above which is lowest in the installed position. Rotate the steering gear manually from lock to lock until no more oil is draining. Unscrewed components must be screwed in again at the following tightening torques: Screw plug (55): 40 Nm (M16x1.5) 50 Nm (M18x1.5)
Page 626
Servicing Work 4.3 Bleeding For steering gear versions with automatic bleeding: Steering gear versions with automatic bleeding do not have any bleed scews. These steering gears automatically bleed any air remaining within the steering system. Note: Automatic bleed valves operate in the idle pressure range only; therefore, any unnecessary pres- sure build-up should be avoided.
Page 627
Servicing Work Versions with bleeder (57): With the engine running, open the bleeder (57) until nothing but oil is coming out (Fig. 7). Afterwards, close the bleeder again until it is oil-tight. On versions without automatic bleeding (installed position horizontal, steering output shaft in the bottom position) the topmost screw/set screw (20 and 128, respectively) can be used for bleeding.
Servicing Work Setting the hydraulic steering limitation A setting of the steering limitation is necessary if or when a new or repaired steering gear is fitted or new screws (20 and 128) were fitted to the automatically adjusting steering limitation or alterations to or adjustments of the front axle were carried out.
