Terberg Rail road locomotive tractors

Differential fluid capacity & service interval

Terberg Rail road locomotive tractors require differential fluid with a capacity of 18 liters. Service intervals include a 100 hour change, a 1 month check, and a 12 month or 1000 hour change. The data covers 12 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Terberg RR 222 6x4 carries 18 liters of differential fluid in each rear axle position, meaning both the leading and trailing differentials hold equal volumes regardless of which engine variant is fitted.
  • An initial service interval of 100 hours applies to both the leading and trailing rear differentials across the OM906LA Stage 3A and OM926LA Stage 3B engine variants, with no monthly check specified for that first change.
  • Under an alternative (acceptable) fluid, the change interval extends to 12 months or 1,000 hours, whichever comes first, and a monthly fluid check is also required for both rear differential positions.
  • Bumpy conditions carry the same 18-liter capacity, monthly check, and 12-month or 1,000-hour change interval as the alternative (acceptable) fluid condition, applying equally to the leading and trailing rear differentials on both engine variants.
  • The 100-hour initial service drain is notably short relative to the 1,000-hour subsequent interval, a gap that reflects the common practice of removing break-in contaminants from gear oil early in a unit's service life.
  • The capacity figure of 18 liters per differential is consistent across all listed configurations, indicating no variation in axle hardware between the Stage 3A and Stage 3B engine fitments on the RR 222 6x4.
