Terex Motor graders

Differential fluid capacity & service interval

Terex motor graders require differential fluid with a capacity range of 8,5 to 9 liters. Service intervals occur every 500 hours. The data covers 2 configurations.

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

  • Change 500 hours
  • TG150-A (2007- )
  • Front
  • Use: Normal
  • Capacity 8,5 liter
  • Change 500 hours

Additional Notes

  • The Terex TG110-A motor grader carries a front differential fluid capacity of 9 liters, while the TG150-A front differential holds 8.5 liters, placing both within a range typical of heavy equipment axle housings rather than light-duty differentials.
  • The 0.5-liter difference between the TG110-A and TG150-A front differential capacities reflects a variation in axle housing volume across the two model configurations, despite both sharing the same service interval.
  • Both the TG110-A and TG150-A specify a front differential fluid change interval of 500 hours under normal use conditions, a figure consistent with standard heavy equipment maintenance cycles for gear oil in planetary or bevel-gear differentials.
  • The 500-hour change interval on both models applies specifically to normal use conditions, meaning operations outside that classification would fall under a separate service regime not represented in the specifications for either model.
  • A 9-liter front differential capacity on the TG110-A indicates a service fill volume, representing the amount of fluid required when draining and refilling the housing during a scheduled fluid change rather than a full overhaul disassembly.
