Range Rover Sport / L494 2017 ACCESSORY DRIVE

You are here:
Estimated reading time: 7 min

The accessory drive is a belt system powered by a pulley attached to the front of the crankshaft. The crankshaft pulley, which incorporates a torsional vibration damper, transmits power to the drive belt. A belt tensioner is incorporated into the belt run to maintain the correct tension of the drive belt. Together with idler pulleys, the belt tensioner also guide the drive belt clear of obstructions and sets the correct ‘wrap-around’ of the accessory component drive pulleys to ensure a slip-free drive.

The belt tensioner consists of an idler pulley on the end of a spring loaded pivot arm. The pivot arm can be turned manually for removal and installation of the drive belt. The belt tensioner is calibrated to automatically maintain the correct tension in the drive belt.

 

PRINCIPLES OF OPERATION

For a detailed description of the accessory drive system and operation, refer to the relevant Description and Operation section of the workshop manual. REFER to:Accessory Drive (303-05A Accessory Drive – TDV6 3.0L Diesel /TDV6 3.0L Diesel – Gen 1.5/TDV6 3.0L Diesel – Gen 2, Description and Operation).

 

INSPECTION AND VERIFICATION

CAUTION:

Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not guarantee confirmation of a fault and may also cause additional faults in the vehicle being checked and/or the donor vehicle.

NOTE:

Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.

  1. Verify the customer concern.

  1. Visually inspect for obvious signs of mechanical damage.

Visual Inspection





MECHANICAL

  • Auxiliary drive belt condition (cracking/damage/contamination)
  • Idler assembly
  • Generator
  • Engine cooling fan
  • Tensioner assembly
  • Engine coolant pump
  • Power steering pump
  • Air Conditioning (A/C) compressor
  • Torsional vibration damper
  • Dynamic response pump
  • Tensioner assembly
  • Auxiliary drive belt
  • Security/correct installation of the fuel injection pump cover
  • Fuel injection pump belt condition (cracking/damage/contamination)
  • Fuel injection pump belt tensioner assembly
  • Fuel injection pump
  • Fuel injection pump belt

  1. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.

CAUTION:

If the engine is run without the auxiliary drive belts connected to eliminate driven components, diagnostic trouble codes, (DTCs) may be set which must be cleared before the vehicle is returned to the owner. The engine should not be run for more than 2-3 minutes with the belts disconnected. Failure to follow this instruction may result in damage to the vehicle.

  1. If the cause is not visually evident, verify the symptom and refer to the Symptom Chart, alternatively check for Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.

 

SYMPTOM CHART (ACCESSORY DRIVE BELT)






SYMPTOM POSSIBLE CAUSES ACTION
Noise

  • Auxiliary drive belt condition
  • Auxiliary drive belt tension
  • Pulleys misaligned
  • Driven components (including tensioners)

  • Check the auxiliary drive belt condition (see visual inspection)
  • Check the auxiliary drive belt tensioner function
  • Check the pulley alignment
  • Check the driven components for excessive resistance to rotation

Auxiliary drive belt does not hold tension

  • Belt condition
  • Tensioner fault

  • Check the auxiliary drive belt condition (see visual inspection)
  • Check the auxiliary drive belt tensioner function

 

SYMPTOM CHART (FUEL INJECTION PUMP BELT)







SYMPTOM POSSIBLE CAUSES ACTION
Noise

  • Fuel injection pump belt condition
  • Fuel injection pump belt fouling cover
  • Fuel injection pump belt tensioner bearing failure
  • Fuel injection pump failure

  • Check the fuel injection pump belt condition (see visual inspection)
  • Check the fuel injection pump belt cover for indications of fouling (this may indicate a pump misalignment), refer to the relevant workshop manual section
  • The fuel injection pump belt tensioner must be renewed if the belt is removed, making a check of the bearing impractical
  • Remove the fuel injection pump belt, check the fuel injection pump pulley for security. Check the fuel injection pump for excessive resistance to rotation (excessive resistance in the pump will cause the pulley securing nut to loosen as a design feature). Check for diagnostic trouble codes (DTCs) indicating a pump malfunction

Fuel injection pump belt does not hold tension

  • Fuel injection pump belt condition
  • Tensioner fault

  • Check the fuel injection pump belt condition (see visual inspection)
  • Check the tensioner function

Loss of drive (with no drive to the fuel injection pump, the engine will not run)

  • Fuel injection pump belt broken / stripped teeth
  • Drive pulleys loose

  • Investigate the cause of the fuel injection pump belt breakage/damage (a belt broken at a 45 degree angle normally indicates a shear, a break straight across the belt normally indicates that the belt has been crimped).
  • Check the fuel injection pump for excessive resistance to rotation (excessive resistance in the pump will cause the pulley securing nut to loosen as a design feature). Check for DTCs indicating a pump malfunction

For a list of Diagnostic Trouble Codes (DTCs) that could be logged on this vehicle, please refer to Section 100-00. REFER to:Diagnostic Trouble Code Index – TDV6 3.0L Diesel /TDV6 3.0L Diesel – Gen 1.5/TDV6 3.0L Diesel – Gen 2, DTC: Powertrain Control Module B10A2-07 to P02D7-32 (100-00 General Information, Description and Operation).

WARNINGS:

  • Do not carry or operate cellular phones when working on or near any fuel related components. Highly flammable vapors are always present and may ignite. Failure to follow these instructions may result in personal injury.

  • Do not carry out any repairs to the fuel system with the engine running. The fuel pressure within the system can be as high as 1650 bar (23,931 lb-sq-in). Failure to follow this instruction may result in personal injury.

  • Do not smoke or carry lighted tobacco or open flame of any type when working on or near any fuel related components. Highly flammable vapors are always present and may ignite. Failure to follow these instructions may result in personal injury.

  • This procedure involves fuel handling. Be prepared for fuel spillage at all times and always observe fuel handling precautions. Failure to follow these instructions may result in personal injury.

CAUTIONS:

  • Make sure the workshop area in which the vehicle is being worked on is as clean and as dust free as possible. Foreign matter from work on clutches, brakes or from machining or welding operations can contaminate the fuel system and may result in later malfunction.

  • Always carry out the cleaning process before carrying out any repairs to the fuel injection system components. Failure to follow this instruction may result in foreign matter ingress to the fuel injection system.

  • Diesel fuel injection equipment is manufactured to very precise tolerances and fine clearances. It is therefore essential that absolute cleanliness is observed when working with these components. Always install blanking plugs to any open orifices or lines. Failure to follow this instruction may result in foreign matter ingress to the fuel injection system.

  • Do not disassemble or clean inside the fuel pump, even with an ultrasonic cleaner. Always install a new fuel pump when required.
