Challenger 1000 series

Differential fluid capacity & service interval

Challenger 1000 series uses differential fluid with a capacity range of 14,3 to 18,5 liters. Service intervals occur every 1000 hours or 12 months. The data covers 4 configurations.

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

Additional Notes

  • Front differential fluid capacity across the 1038 Gen2, 1042 Gen2, 1046 Gen2, and 1050 Gen2 models measures 14.3 liters for service fill operations.
  • Dry fill capacity for front differential fluid on all four Gen2 variants reaches 18.5 liters, representing the total volume when the differential assembly contains no residual fluid.
  • The difference between service fill and dry fill capacity amounts to 4.2 liters, indicating the volume of fluid retained in the differential system during normal operation.
  • Front differential fluid change intervals are specified at 1000 operating hours or 12 months under normal use conditions, whichever occurs first.
  • Uniform specifications across the 1038 Gen2 through 1050 Gen2 range indicate consistent front differential design and fluid requirements across all displacement variants in the Gen2 series.
