Terex Telehandlers

Transfer case fluid capacity & service interval

Terex Telehandlers use transfer case fluid with a capacity range of 1,5 to 2,7 liters. Service intervals include checks at 1 month or 250 hours and changes at 6 months or 1000 hours. The data covers 3 configurations.

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

Additional Notes

  • The Terex Telehandlers transfer case fluid specifications cover three Terexlift models, each with a distinct transferbox capacity: 1.5 liters for the TX 66-41, 2.2 liters for the TX 110-72R, and 2.7 liters for the TX 77-45R.
  • The TX 77-45R carries the largest transferbox fill volume at 2.7 liters, which reflects the greater fluid demand of a higher-capacity unit relative to the other two models in the range.
  • The TX 66-41 has the smallest transferbox capacity at 1.5 liters, roughly half that of the TX 77-45R, indicating a meaningfully different unit size between the two configurations.
  • Two of the three models, the TX 110-72R and the TX 77-45R, share an identical service structure: a fluid level check interval of every 1 month or 250 hours under normal use conditions, paired with a fluid change interval of every 6 months or 1,000 hours.
  • The TX 66-41 specifications list only a change interval of 1,000 hours under normal use, without a separate check interval, distinguishing the service schedule from the other two models.
  • The 250-hour or 1-month check interval on the TX 110-72R and TX 77-45R reflects a time-based threshold that can be reached before the hour-based threshold in lower-utilization applications, making the calendar interval the governing factor in those cases.
  • Across all three models, the fluid change interval converges at 1,000 hours, establishing a consistent maximum service life for the transferbox fluid regardless of the differing capacities involved.
