NOTE: There are four (4) different methods for converting fault codes. The PowerView alwayslooks for J1939 Version 4 and can be set to read the code as one of three (3) other J1939versions if Version 4 is not being used. Most engine ECU’s use Version 4, therefore in mostcases adjustment of this menu option will not be required.Upon receiving an unrecognizable fault, change to a different J1939 Version. If the fault SPNdoes not change when the version is changed, the ECU generating the fault is using FaultConversion method 4. If the SPN number does change but is still unrecognizable, try changing toanother J1939 Version not yet used and continue to check the SPN number.

5. ANALOG INPUT – provides two setting options:

� BACKLIGHT DIMMER, the default setting, will accept an optional backlighting dimmer.� FUEL LEVEL accepts an optional Murphy fuel sender (model ES2F recommended) for fuellevel information.

2.1.8 Engine Coolant Radiator

The radiator pack at the front of the engine also has a hydraulicoil cooler attached at the front.

IMPORTANTThe radiators must be kept clean and free ofobstruction AT ALL TIMES.

To clean the engine radiator –

Release the bottom hydraulic hose (from oil cooler) fromclamp under chassis (next to hydraulic reservoir).

Releasing the wing screws on the front of the radiator allowthe hydraulic radiator to PULL FORWARD so that the mainengine radiator may be cleaned. Release the bottomhydraulic hose from its clamp on the chassis to fully movethe radiator.

Use compressed air or a nylon brush to clean the radiatorof any build-up.



2.1.9 Engine Air Intake Cleaner

The air cleaner is fitted with a vacuum gauge linked to a warninglight in the main console. When blocked the air cleaner elementwill need cleaning or replacement.

SPECIFICATIONThe air cleaner consists of a pre-cleaner assembly, whichgenerates a cyclone effect with the incoming air, throwing thelarger dust particles to the outside. The particles are thensucked into the exhaust and ejected. It is important to ensurethe pipe between the pre-cleaner and exhaust is in place andundamaged.

The air is then drawn into the main air cleaner containing twopaper elements, inner and outer. The inner element acts as asafety element should the outer element becoming damaged.

The vacuum sensor will illuminate the instrument warning lightwhen the element has become blocked and is restricting air flowto the engine.

The air compressor also takes its inlet air from the air cleaner.

MAINTENANCERemove the elements by unclipping the end housing and holdingfirmly; draw back the outer element; it is held by a rubbergrommet on the inside that forms an air seal.

Always replace both elements together and ensure the rubberseal is in good condition, they are correctly fitted and the endcap re-fitted. Check also the hose and pipe from the air cleanerto the engine is in good order and the band clamps are tight.Any gap can lead to air being drawn directly into the enginecausing wear and failure.

IMPORTANTIf any of the air cleaner pipework to the engine is damaged,the vacuum gauge is lost or sealing bands are broken,replace these immediately before continuing to use themachine.

The following four pages have specific information on theservicing procedures for the air cleaner filter elements.

2.2 Hydrostatic Transmission, Controls & DriveAxles

2.2.1 Hydrostatic Circuit

SpecificationThe hydrostatic drive is a closed loop, high pressure hydrauliccircuit. It consists of -

One variable displacement piston pump with electric overhydraulic control. Pump fitted with its own charge/boostgear type pumpandone variable displacement piston motor to gearbox, withhydraulic control.

See circuit diagram SE701-01

Variable displacement pump 100 cc/rev at max displacementBoost pump output 20 cc/revMain relief valve pressure 320 bar (built into pump)Boost pressure 24 bar (relief)Min boost pressure 20 bar

Variable displacement motor 110 cc/rev at max displacement 62 cc/rev at min displacement

Boost Pressure & FiltersThe boost pressure MUST be maintained for the hydrostatictransmission to perform correctly.

To measure boost pressure, there are gauge ports inboth pumps. These are located in the top of the pumpsattached to the porting for circuiting the boost flowthrough their filters.



Pump/Motor Signal ValveThe control signal used to operate the motor from the pump isisolated to the motor in LOW range to limit the speed to 4.2 kph.Otherwise the ground speed in low range would be 7.2 kphmaximum.

The signal valve is positioned on the inboard side of the RHSconveyor immediately above the drive motor & below the pressurefilter.

To override this valve and allow the motor to changedisplacement in LOW speed, set the valve manual override intothe MANUAL POSITION.

Drive Motor Displacement Isolator Valve

NORMAL MANUALPOSITION OVERRIDE

To set to manual either, unscrew fully the head of the hydrauliccartridge, or alternatively push and twist the bayonet cap torelease the valve head.

If the valve fails to operate correctly, the High speed range willalso not achieve full speed of 28 kph but will be limited to 16kph.

MaintenanceThe hydrostatic circuit uses all Sauer-Danfoss components, as isthe control circuit and joystick, which do not require any regularmaintenance.

In the event of system performance failure, either contactPhoenix Engineering or your local Sauer-Danfoss dealer forassistance.



Pump priming –In the event of a major hose failure or hydraulic oil leak,the hydrostatic pumps will need priming with oil BEFOREstarting. This will prevent internal failure through poorlubrication.

When priming the circuit it is recommended that the enginebe turned over, but prevented from starting, until hydraulicoil has completely entered all of the circuit.

If dismantling the hydrostatic circuit, it is recommended thatspecific information on the pump and motor servicing beobtained first from Phoenix Engineering or Sauer Danfoss.

CleanlinessAt any time, when the circuit is dismantled, it is mostimportant to ensure dirt is not allowed to enter. All hoseunions or ports must be kept sealed and be cleaned beforebeing re-assembled.

2.2.3 Brake Circuit

Brake SpecificationThe brakes consist of

• Front & rear axle internal wet disc brakes, hydraulicallyoperated ON for service braking.

• Rear axle calliper hydraulically operated brakes, forparking/emergency braking.Brake sprung applied & pressure released to fail safe.

• Gearbox multi pack brake for parking/emergency use.Brake sprung applied & pressure released to fail safe.

Hydraulic Brakes CircuitBrake operation has three independent circuits that are all fittedwith accumulators to allow limited brake operation should thepower fail. Approximately 5 service and park brake operationsare possible before reserve hydraulic pressure is lost.

See circuit diagram SE703-01

Stored energy accumulators are used in the brake circuit. Theseretain pressure when the power (engine) is off. This allows for upto five brake operations until the reserve is exhausted.

IMPORTANTIf dismantling the hydraulic joints pressure in the lines willneed to be released. Operate all brake functions ten timesto drain the reserve pressure.

MaintenanceThere is no regular service needed to the brake controlcomponents. If these components fail to perform to specification,they must be replaced IMMEDIATELY.The hydraulic circuit used oil from the main hydraulic reservoirand does not have its own supply.The calliper brake pads need annual inspection.

See the ITL axle section for information on the maintenance ofthe axle’s brakes.



Calliper Brake AdjustmentThe calliper brake should be inspected and adjusted annually.

Inspection –Check that the disc is in good order and there is no debrisor oils on the disc or pads.Check the wear on the pads, if worn, more that 2mm oneach pad, replace pads.Check for oil leaks from calliper piston or hose connection.

Calliper Brake Assembly

Adjustment –1. Chock wheels.2. With hydraulic circuit charged (engine must have run

but not running during adjustment), set brake toOFF/release brake.

3. Loosen the central lock nut and adjusting screw.4. Place a 0.30mm [0.012”] thick shim between the disc

and one lining.5. Tighten the adjusting screw until it is just possible to

remove the shim.6. Tighten lock nut while holding the adjusting screw with

a spanner. Remove shim and release pressure frombrake – set handbrake ON.



Manual Brake Release & TowingThere are two park/emergency brakes on the machine. In theevent of hydraulic power failure, the machine will not move. Totow the machine the park brakes will both need to be released.

Gearbox brake, see gearbox maintenance section 2.2.4

Calliper brake – screw the central bolt fully OUT, until thebrake pads fully release from the disc.

See hydraulic circuit SE703-03

Feedroller CircuitEach of the three feedrollers is driven by its own high torque,low speed hydraulic motor, as are the two extension agitators.The centre section feedroller and agitator are driven throughchain and pinion. The motor is mounted onto a plate that can beadjusted in increase drive chain tension. The extensionfeedrollers and agitator drive directly into their shafts.

The flow from the hydraulic pump is feed into the main controlblock. This block contains a main relief valve, a solenoidproportioning flow control valve and a pair of solenoid valves foreach feedroller (R1,R2 &R3) The circuit feeds the centrefeedroller (R2) then left hand extension (R1) and last the righthand extension feedroller (R3), all in series, to maintain equalspeeds on the feedrollers.

Each feedroller has its own control switch that acts upon thatpair of solenoid valves, so each feedroller is individuallycontrollable ON/OFF in any sequence. The master switch (onJoystick) will trigger the proportional flow control to allow flowinto the remaining part of the circuit.



The pair of solenoid valves consists of one normally open ‘NO’and one normally closed ‘NC’. Both are de-energised when thefeedroller is stationary and energise to engage the feedrollermotor. The ‘NO’ solenoid normally allows the flow to divert pastthat feedroller to the next and from there back to the hydraulicreservoir. Each ‘NC’ solenoid shuts the circuit to the feedrollerso stopping the motor from rotating.

On the centre section feedroller there is a check valve mounteddirectly next to the motor to counteract a small amount ofcounter rotation when the circuit closes at the solenoids.

The solenoid valves will operate in the following sequence.

Master ‘OFF’ - All solenoid de-energised, allfeedrollers ‘OFF’

Master ‘ON’ & R2 ‘ON’- 1st pair solenoids energised,centre feedroller only operates.R1 and R3 ‘OFF’, 2nd and 3rd pair of solenoids de-energised.

Master ‘ON’ & R1, R2, R3, ‘ON’ - all solenoidsenergised (6 no.) all feedrollers operate

The proportioning solenoid valve allows a proportion of the totalflow into the circuit that is a function of ground speed and thesetting of the FeedRoller Speed Adjuster. The bypassed flow ispassed into the tank line.

The optional extension hopper agitators have a manuallycontrolled hydraulic block mounted directly to their motors.This hydraulic block contains a diverter valve.

HAZARD WARNINGThe central position has a detent location in whichthe lever must be set to disengage the agitator; failureto correctly position the lever can restrict the flowcausing excessive load and heat to build up.

2.3.2 Hydraulic Oil Reservoir & Oil Cooler Radiator

Hydraulic Oil Reservoir SpecificationSuction filters are fitted inside the hydraulic reservoir.

To clean the suction strainers –The strainers may be removed through the fittingconnected to the reservoir. Remove from the reservoir andplace into a cleaning drum of kerosene. Carefully wash outthe mesh strainer and clean all particles that havecollected in the mesh.Check for damage or holes in the mesh. Likewise thediffuser mesh.

IMPORTANTDO NOT re-fit to machine any suction strainer thathas become damaged. It must then be replaced.

Return Line Filter – Auxiliary circuitsTwo are located in front of engine radiator

These are fitted with a pressure indicator that shows whenthe filter has become blocked. The indicator shows aGREEN or RED band when the engine is running (with theoil at operating temperature).

2.4 Spreading System & Aggregate Handling

2.4.1 Front Spreading Hopper

SPECIFICATIONCentre spread hopper with feedroller, feedgate, agitator, drivesystem and 296mm wide individual shut-off-doors raised bypneumatic cylinders.Two extension hoppers with feedrollers, feedgates, optionalagitators and drive systems.Extension rail support front and rear with hydraulic rams toextend and retract hoppers.

MAINTENANCEThe feedrollers and feedgates must be kept in good order, toensure the performance of the spreading system is maintained.

Weekly, the threads on feedgate adjusters should be cleaned andtreated with a spray lubricant (such as WD40 or similar).

Check the feedgate mesh remains in good order and does notwear away or locally lift off the feedroller surface. It mustremain tightly held onto the drum surface.

When the feedroller mesh requires replacement, (less than 2mmthickness remains) the feedgate rubber, cut-off-door rubber andfeedroller scraper rubber should also be changed at the sametime.

To replace the feedroller mesh, dismantle from the hopper andremove the old mesh from the roller with a hand chisel, breakingthe welds. Lightly grind the surface to clean off the old weld.DO NOT grind off the mesh or use heavy grinding on the surfaceof the feedroller as excessive heat can cause it to distort. Placea pre-rolled mesh over the feedroller and clamp into place sothat it tightens down fully onto the surface. Weld short runsalong both ends and seam so that no loose edges are left.

When the length of the feedroller requires more than one sectionof mesh, stagger the longitudinal join so that there is not acontinuous line of weld at one point for the full length.

Fixed on each end of each feedroller is a large diameter disc.There are plates that closely fix over them (centre feedroller) oron to their outside edge (extension hoppers) these should be



adjusted or replaced as they wear, to prevent aggregatebecoming jammed behind the end of the feedroller and thehopper outside plates.

IMPORTANTDo not allow the feedroller to bow out of shape. Adistortion of even 1mm will lead to uneven spreadingcharacteristics.

When replacing the feedgate rubber, care must be taken toensure the bottom edge remains perfectly straight.

The feedroller scraper rubbers should be adjusted so that anygap behind the feedrollers is closed up. However, they shouldnot be pushing onto the surface of the feedrollers.

The separate feedgates must all remain parallel to the feedrollerwhen replaced. Check by allowing feedgate rubbers to rest onthe feedroller so that along their full length they rest equallyonto the feedroller.

The agitator shaft has eccentric discs welded on to break uplumps of aggregate. These discs will wear away when frequentlyused and should be replaced. The remains of the old disc shouldbe ground away and new ones welded in their place.

The extension hopper support rails, front and back, is held onnylon wear pads. These will only wear very slowly and, should innormal use, last the life of the machine. If however the hopperbecomes slack on the rails additional packing can be placedunder the pads to take up this wear.

The scatter plates at the front of each hopper should be kept ingood condition and retain their straightness. If they becomedamaged or bent, they should be immediately repaired orreplaced.

When the feedrollers or agitators are removed from the machine,the bearings in which they rotate should be checked. Regulargreasing is not required, but they should be free running. Thebearings should be locked to the shaft to prevent movementthrough the bearing occurring.

The extension hopper cut-off plates, located above the extensionfeedroller and sliding over it, will catch aggregate. It should befully cleared and any aggregate fouling the slot in the extensionhopper removed. The level of wear on the end pushed though the



aggregate must also be checked, as this can affect the overlapwhen excessive wear occurs.



2.4.2 Conveyors

SPECIFICATIONConveyor belt size: Twin 450 wideConveyor belt pattern Flat profile with sweeper cleats or

chevron patternTrough angle: 20ºHead/drive drum: Rubber lagged to give tractionFastener / Hinge: Wire rope type, removable connector

MAINTENANCE

Belt tension : The belts will drive satisfactorily with very littletension. This can be seen in the way the belt hangs down betweenthe return idlers.

To adjust belt tension, slacken the nuts on the tail drum adjusterscrews and draw the tail drum down the slot, until sufficient tensionis applied. Re-secure the nuts on the tensioner.

Do not over tension the belts, as they will stretch if pulled too tight.Only adjust the minimum amount if belt to drive drum traction islost and they slip on the drive drum.

Always ensure the tail drum remains square to the elevator beltand parallel to the head drum. Always adjust by the same amounton each of the screws.

Conveyor belt tracking : If the belt, at the top or bottom, runs to oneside use the following procedure to centralise it.

1) Ensure the head drive drums and tail drums are square andparallel to the machine’s structure.

Never try to track the elevator belts by moving either thehead or tail drums out of square.

2) The idler rollers are in slotted holes, to allow them to bemoved at a slight angle to the belt.

If the belt is moving to the left on the load (top) side, adjustthe idler on the left, at the beginning of the misalignment,forward. This has the effect of moving the belt back towards



the centre. Alternatively, move the right hand side of theidler back.If this does not bring the belt sufficiently back into thecentre, move to the next idler up and adjust its position,Carry on until the belt tracks into the middle on the headdrum.

3) If the belt is moving off centre on the return side, and the beltis off centre on the tail drum, move the return idlers forwardon the side the belt is moving towards.

4) Securely lock all the idlers after the elevator belt has beentracked. The elevator belt tracking should be checkedweekly.

Idler rollers : These have sealed for life bearings inside them and should bechecked annually to ensure that none have seized. Weekly,the return idler should be checked to ensure that the rubbersupport wheels are not in contact with the cross lugs. Thecross lugs can be pulled off by being constantly hittingagainst these rubber wheels, causing then to be strippedfrom the belt surface.

Adjustment of front hopper sensors:The level switch / float, will detect when the front hopper isfull and stop the elevator belt on that side. The position ofthe arm and the angle at which it will switch the elevator beltON/OFF is adjustable.

The vertical position of the float can be adjusted by movingthe arm through the pivot assemble. The higher the floatposition the greater the front hopper will fill before the beltsare stopped. The angle at which the switch is ON and OFF isadjusted by slackening the pilot assembly on the splinedshaft of the switch and moving it to a new position so thatthe switch is off in the vertical position and switches on atthe correct angle to sense the hopper is full. Re-secure thepivot assembly when the angle of the switch and float iscorrect.

NoteThe switch is open (OFF) when the elevators are operatingand closed (ON) when the elevators are stopped.



2.4.3 Rear Receiving Hopper

MAINTENANCEThe folding side hinges should be lubricated weekly. The hinge pin can beremoved rearwards to release the folding side. The rubber around the backof the hopper needs replacing when it becomes damaged.

The elevator belt aperture and rear flap rubber needs changing only whenheavily worn.



Tow Hook Attachment



2.4.4 Tow Hook

SPECIFICATIONSupported on a rubber/elastic bush to allow angular movement and toabsorb shock loads, the bush will gradually ‘relax’ causing the tow hook’sposition to drop.

The tow hook is operated by a two way hydraulic ram.

To Re-Position HookTo re-position the hook when the bush has relaxed, slacken the three caphead set screws, holding the bush into the bracket, until the bush outerring can rotate inside the bracket. Lift the tow hook until positionedcorrectly and re secure the cap head screws.

When the rubber / elastic bush no longer maintains its flexibility, it willrequire replacement.

See section 4.4 for details of tow hook truck attachment layout.
