SECTION 10 – ENGINE – CHAPTER 1

Inspection and repair of gears

1. Wash the gears using a suitable solvent, and examine gear teeth for wear, burrs, or scratches. Minor marks can be removed using a fine abrasive, thoroughly clean before re-assembly.

2. Ensure the camshaft idler gear adaptor is free from obstruction and bushing is not damaged. Camshaft key and key-way should be checked for damage and repaired as required.

Installation

1. If the rear cover was removed thoroughly clean the mating surfaces between the cover and engine block, using a suitable solvent cleaner and carefully apply a thin bead, approximately 2mm, of the recommended flexible gasket sealant, Type ‘L’, to the cover. Assemble the cover to the engine and tighten the two lower retaining bolts to a torque of 37Nm, (281bf.ft.) and the remaining four bolts to a torque of 24Nm (181bf.ft)

2. Position piston no.1 at Top Dead Centre, install the spacer, key, and camshaft gear, and tighten to 69N m (51 lbf ft) Figure 49.

3. Install the camshaft idler gear to the block, aligning the timing marks to the crankshaft and camshaft gears. Install the eccentric adjuster into the idler gear and initially position the larger of the two holes of the eccentric in the 6-9 O’Clock position, relative to the oil pan face of the block.

4. With piston No1 at Top Dead Centre, assemble the ‘LOCKED’ pre-timed fuel injection pump with a new ‘0’ ring, aligning the mark on pump flange to the timing mark on the front cover.
Torque pump retaining bolts to 24Nm (18 lbf ft). Install the pump gear over the pump shaft. Assemble the washer and nut to the shaft, leaving loose at this stage to allow the gear to
rotate freely on the pump shaft. Holding the idler gear, check the backlash between the pump and idler gear with a feeler gauge or dial indicator. If the backlash is outside the specification of 0.01 0-0.015mm (0.004-0.006in), rotate the eccentric until the backlash is correct and tighten the idler gear retaining bolt to a torque value of 242Nm (1801bf.ft.).

NOTE: DO NOT TIGHTEN THE INJECTION PUMP SHAFT NUT AT THIS STAGE. PROCEED TO REASSEMBLE THE FRONT COVER.

Functional description
The hypoid rear axle for buses is described in this repair manual.
The axle is designed for an exceptionally long, maintenance-free service life. The axle is a live, non-steering rigid axle with a single reduction ratio. There is a choice of reduction ratios available for the axle drives. This axle is installed as a single axle.
The power flows from the gearbox to the rear axle input flange via the propshaft.
The power flows from the input flange to the rear axle via the countershaft gears, drive pinion/crown wheel, differential and axle shafts. From here, the power is transmitted to the wheel hub and the driven wheels.
The axle drive consists of the drive pinion/crown wheel assembly and the differential. The differential function is provided by a differential spider. The input flange has cross serrations.
The axle housing is made from fine-grained steel and is oil-tight. The two steel axle journals are welded to the axle housing. The flange for locating the sliding calliper carrier is welded onto the axle housing.
The brake is a compressed air-operated sliding-calliper disc brake with automatic adjustment and a continuous wear indicator. It is a single unit comprising service brake, auxiliary brake and parking brake. It is operated mechanically by means of a combination brake cylinder directly on the sliding calliper. The automatic adjustment feature takes effect depending on the degree of wear and operates with a fixed clearance.
The internally ventilated brake discs are bolted onto the wheel hubs.
The ABS consists of a ring with built-in speed sensor, which is shrunk onto the axle housing (axle tube). The ABS pulse generator for the ABS speed sensor is part of the hub-unit wheel bearing unit and is pressed into the wheel hub.
The hub-unit wheel bearing unit is a “constructed” encapsulated wheel hub bearing unit and constitutes a single component.
The wheel hub, bearing, rotary shaft seals and ABS pulse wheel (rotor) are assembled into an encapsulated unit.
These wheel bearings are not adjustable and have a lifetime grease filling for lubrication. No measurable clearance is permitted on the hub-unit wheel bearings.
The brake pads are asbestos free. A checking device informs the driver when the wear limit is reached.
The parking brake is applied via the brake cylinder spring actuators.

7.2.2.4 Operation test of steering servo system – fly by wire
1. Log on the truck and check that the operation of the end stops in both directions is correct.
2. Turn the mini wheel clockwise to the maximum. Connect the red/black cable with the pink/black cable coming from X18’s connection closest to the servo box. Turn the steering to the centre position. After approx. 10 mm of movement on the gearbox the servo contactor should open. Check that the brakes are properly applied and that it is not possible to drive the machine. If
the brakes are not on and the machine can be driven then the circuit must be checked. The drive controller E1 is supplied from the servo contact E4 pin 8.
Check that pin 8 is not live, if it is – replace the servo box. Reset using the off-on buttons on the keyboard.
3. Brown/white cable. Perform the equivalent procedure with the switch by connecting together the red/black cable with the brown/white cable.
4. Pull apart the connector P14 (tied to the return hose on UNS). The servo contactor should open and it should be impossible to release the brake; it should also be impossible to drive the truck. Connect P14 again.
5. Pull out the motor fuse for the servo motor (F4). The servo motor should
open and it should be impossible to release the brake; it should also be impossible to drive the truck. Fit the fuse again.
6. If it is possible to release the brake after points 2, 3, 4 or 5 have been implemented, or it is possible to drive the truck, the truck must be checked carefully and not used until the fault has been rectified.
7. Finally check that the drive unit does not hit the mechanical stop in the end
positions.

7.2.2.5 Mechanical adjustment to the steering sensors – EPS 2001/ EPS AC0
With the gear box on the seat side of the truck, turn the drive wheel anticlockwise a little over +90 degrees (Circa +100 degrees) ensuring that the cam on the drive unit is located under both threaded holes for the sensors.
Screw in the sensor (follow with the cable to avoid twisting) until it reaches the bottom on the cam. Then unscrew the sensor a 3/4 turn and lock the sensor with the nut.
Important!
The nut is to be locked using thread locking solution. However, make sure that the thread locking solution is not applied in the threaded hole.

7.2.2.6 Operation test of the steering sensors – EPS 2001/EPS AC0
1. With the gear box on the seat side of the truck, turn the drive wheel anticlockwise a little over +90 degrees (Circa +100 degrees) ensuring that the cam on the drive unit is located under both threaded holes for the sensors.
2. Switch off the truck.
3. Disconnect the cable to the steering sensor.
4. Unscrew the steering sensor (follow with the cable to avoid twisting).
5. Reconnect the cable.
6. Start the truck and log on.
7. Hold the sensor top against some metal (iron, steel, etc).
8. Make sure that the sensor has the correct status by checking the menu “Logged on service”:
9. The steering sensor must be active when metal comes within about 2 mm of the sensor top.
10. Reinstall the sensor as described in section 7.2.2.5.

EXCERPT:
Air Suspension System Amended
“Description”
“The vehicle is fitted with air suspension, a function of this is the facility to kneel the vehicle at the front, or when fitted, an option to lower the suspension all round.”
“The air suspension is supplied from an auxiliary tank, sited on the right hand side of the chassis and forward of the battery carrier. Output supply passes through the system line filter, which filters the air before it enters the solenoid valve block and the levelling valves. Foreign matter in these items may cause them to malfunction.”
“Levelling valves are fitted to the front and rear axles of the vehicle. The levelling valves have a neutral or zero setting and at this position the vehicle ride height is set. Should the vehicle experience an increase in load, the chassis will move nearer to the ground resulting in the connection linkage pushing up and the valve spindle turning clockwise. This results in the valve allowing more air to be pumped into the air bags until the original ride height is achieved, although at a greater pressure. For a decrease in load the reverse happens, with the supply pressure shut off and the air bag pressure exhausting, the correct ride height is obtained.”
“For the kneeling system this function is controlled by a solenoid valve block and electrical relays via “”Raise”” and “”Kneel”” buttons in the drivers cab.”
“A proximity switch is fitted on the vehicle. The switch senses movement past a fixed indicator on the front axle. The indicator is sited at approximately half distance of its full travel. When the switch senses this indicator, the level warning light (yellow) will come on and the vehicle can be stopped at any point while the light is on. If the button is released before the light comes on the vehicle will return to a normal ride height.”

“When the kneel button is pressed valves 42 and 43 are energised. Valve 42 will be put in the open position and simultaneously valve 43 will close. The closing of valve 43 isolates the front levelling system and stops the levelling valve exhausting or inflating the air bags. Opening valve 42 allows the front air bags to exhaust, allowing the vehicle to kneel.”
