Therefore in this case only Section 2 of the assessment can be conducted IMPORTANT: Please note that should the steering column/steering wheel vibrate at any point when conducting Sections 1 and/or 2, the operative can STOP the assessment and go straight to Section 3 Section 1 – Conduct this section with the engine and transmission cold * Cold temperature is defined as follows: When the engine has been switched off for a period of four hours or more ** Normal operating temperature is defined as follows: After the vehicle has been driven at 50kp/h or 30 mph for a period of 30 minutes Ensure the location chosen for the onward procedure is suitable ensuring there is enough space to conduct the manoeuvres safely INTERNAL 1) Test Method – Cycle 1 – Left hand lock – Forward gear selected • • Referring to Figure 1 - With the vehicle in a stationary position - Apply the footbrake – Turn the steering wheel to full left lock (hold the steering wheel onto the lock stop) Release the footbrake and allow the vehicle to accelerate to its natural creeping speed with no accelerator pedal input • The vehicle should complete (one) 360° circle at this speed • Should the noise/vibration occur, release the full lock to confirm if the noise/vibration decreases – if the noise decreases go straight to Section 3 Cycle 2 • With the vehicle in a stationary position - Apply the footbrake – Turn the steering wheel to full left lock (hold the steering wheel onto the lock stop) • Release the footbrake and allow the vehicle to accelerate swiftly to 15 kp/h or 10 mph • The vehicle should complete (one) 360° circle at this speed • Should the noise/vibration occur, release the full lock to confirm if the noise/vibration decreases – if the noise decreases go straight to Section 3 Figure 1 2) Repeat Cycles 1 and 2 with full right hand lock – Forward gear selected 3) Repeat Cycles 1 and 2 with full left hand lock – Reverse gear selected 4) Repeat Cycles 1 and 2 with full right hand lock – Reverse gear selected Section 2- Engine and transmission should be at Normal operating temperature 1) Test Method – Cycle 1 – Left hand lock – Forward gear selected • Referring to Figure 1 - With the vehicle in a stationary position - Apply the footbrake – Turn the steering wheel to full left lock (hold the steering wheel onto the lock stop) • Release the footbrake and allow the vehicle to accelerate to its natural creep speed with no accelerator pedal input • The vehicle should complete (one) 360° circle at this speed • Should the noise/vibration occur, release the full lock to confirm if the noise/vibration decreases – if the noise decreases go straight to INTERNAL Section 3 Cycle 2 • With the vehicle in a stationary position - Apply the footbrake – Turn the steering wheel to full left lock (hold the steering wheel onto the lock stop) • • Release the footbrake and allow the vehicle to accelerate swiftly to 15 kp/h or 10 mph The vehicle should complete (one) 360° circle at this speed • Should the noise/vibration occur, release the full lock to confirm if the noise/vibration decreases – if the noise decreases go straight to Section 3 2) Repeat Cycles 1 and 2 with full right hand lock – Forward gear selected 3) Repeat Cycles 1 and 2 with full left hand lock – Reverse gear selected 4) Repeat Cycles 1 and 2 with full right hand lock – Reverse gear selected Section 3 - Front and centre differential - To check and fill Within this procedure there are single use items (Drain/fill plugs and differential oil cooler feed pipe seals) ensure that new replacements are available prior to starting this procedure. 1) Referring to Rep.Gr 39 - Front and centre differential – To check and fill - locate the front and centre differential oil drain points • Drain the oil from the front and centre differentials 2) Referring partially to Repair.Gr 39 – Differential oil cooler – To remove and fit – Disconnect the oil cooler pipes to drain all the oil from the cooler and cooler pipes (Do not remove the cooler) • Once all the oil is drained from the pipes and cooler, refit the differential cooler pipes ensuring new cooler feed pipe seals are fitted as per Repair.Gr 39 – Differential oil cooler – To remove and fit instructions 3) Referring to Repair.Gr 39 – Carry out the Front and centre differential – To check and fill procedure Warranty accounting instructions Road test Warranty Type 110 or 910 Labour operation code 01 21 00 00 Damage Service Number 39 90 Damage code 00 55 Time 50 Time units Front and centre differential oil drain/check and fill Warranty Type 110 or 910 Labour operation code 39 90 55 10 Damage Service Number 39 90 Damage code 00 55 Time 200 Time units Parts information Please refer to Elsa pro instruction regarding single use items, Refer to ETKA parts catalogue for the required single use parts (Drain/fill plugs and differential oil cooler feed pipe seals) and the front/centre differential oil NOTE: The drain and fill plugs are not provided individually as they are supplied in a kit which has all the required plugs for this procedure, extra plugs will also be provided however only the front and rear differential drain and fill plugs are required INTERNAL
