H-E Parts was approached by an oil sands customer in Alberta, Canada. The customer sought help on GDY85 wheel motors for Komatsu 930E haul trucks and wanted to achieve a lower cost per hour by increasing target life on the components. H-E Parts offered a safe and effective solution.

IMPROVED PERFORMANCE

The GDY85 wheel motors were being changed out at only 16,000 hours. Our engineers examined the failures and developed a plan to rebuild them and improve service life. The following differences separated H-E Parts from our competitors, and assisted in increasing the service life of the customer GDY85s:

  • Birrana™ enhancements: All Birrana™ wheel groups consist of proprietary processes and application specific components that improve service life and machine availability. Additionally, Birrana™ enhancements include a world class wheel motor gearing with specialized alloy steel for teeth and critical surfaces.
  • Upgraded overhaul process: H-E Parts continuously updates the overhaul process. 
  • Flexibility: Our team was able to adjust the rebuilding and selling process to fit the customer’s specific needs. 
  • Proprietary tooling and processes: With high levels of attention to detail and best practice, we give safe and consistent repairs that will achieve appropriate service life every time.
  • Quick response time: Our team was able to deliver a world class schedule to meet customer needs and minimize machine downtime.
