Warnings

ADVICE AND WARNINGS TO FOLLOW BEFORE REPLACING THE TURBO

Before changing the turbocharger, it is essential to fully understand the causes that led to its failure.

The operations described below, are fundamental to avoid a second failure and consequently a warranty claim.

In case of a warranty claim, the execution of these essential replacement/cleaning operations must be demonstrable through an invoice. If they do not appear, the warranty claim will NOT be considered.

 

DEPENDING ON THE IDENTIFIED ISSUE, PERFORM THE FOLLOWING OPERATIONS FOR A CORRECT REPLACEMENT OF THE TURBO.

 

LUBRICATION

- Thorough cleaning and/or replacement of the oil inlet and outlet pipes.

- The turbo failure may have generated metal shavings circulating freely in the lubrication system. Before performing the intervention, replace the lubricating oil along with the respective filter. After the intervention is completed, briefly run the engine to facilitate the removal of impurities and change the oil and filter again.

- Check that the oil pump pickup inside the sump is not clogged. If so, clean thoroughly and/or replace the oil pump.

- Check the efficiency and perform a thorough cleaning of the oil vapor recovery valve.

ASPIRATION ( The turbo whistles during acceleration )

- Check that the air intake hoses of the turbine do not have cracks; if they do, replace them. A small piece of rubber sucked in by the turbo that impacts against the impeller at a speed of 100.000 rpm has devastating effects.

- Change the air filter.

- Clean and/or replace the intercooler and the related hoses.

EXHAUST ( The turbo whistles on release)

- Check the integrity of the internal module of the FAP/DPF/CAT and replace it if necessary. If it is intact perform an internal regeneration/washing.

- Check the efficiency of the EGR valve. Carry out a thorough cleaning of it and the exhaust gas recirculation system ducts.

Techinical Info

The code 178750 identifies a turbocharger for John Deere PowerTech 6.8L (6068H) engines. The unit belongs to the BorgWarner S300V/S300BV family with variable geometry (VGT) and an integrated electronic actuator. It is supplied as a complete assembly (compressor, turbine, CHRA, VGT lever mechanism and positioner).

Technical specifications

  • Type: VGT turbocharger with 12 V electronic actuator/positioner and integrated position sensor
  • Manufacturer family: BorgWarner
  • Lubrication: oil-lubricated with dedicated feed/return lines; priming required during installation
  • Interfaces: turbine volute with variable vane pack; compressor volute toward the air-to-air intercooler

DIPA can intervene to overhaul this component as well, which is so important for the correct operation of the engine.

Functions

  • Continuous VGT adjustment to maximize low-end torque, reduce turbo lag and optimize boost pressure
  • Integration with the ECU for thermal protection strategies and pressure limiting
  • Support for EGR/aftertreatment management, with fine control of exhaust flows

Model applications

  • John Deere: platforms with the 6068H engine in agricultural/industrial applications of the same generation (tractors and related machines in the 6.8L power class)

Typical faults

  • VGT electronic actuator failure
  • Vane seizure/reduced performance
  • Oil leaks/smoke from the exhaust
  • Cracks on the volute

Final conclusions

The 178750 is a BorgWarner S300V/S300BV dedicated to PowerTech 6.8L engines, widely used on JD platforms and OEM applications with the 6068H engine.

DIPA offers a wide range of spare parts dedicated to the Agri sector: from vehicle-related parts to those for auxiliary equipment. Not only that: it has reconditioned components with performance equal to new, allowing cost savings on replacements while contributing to environmental protection through the circular economy. If the spare part you need is not available, don't worry: DIPA can overhaul your part “on demand”, returning full functionality and safety in a short time.
