Hidromek Backhoe loaders

Automatic transmission fluid capacity & service interval

Hidromek Backhoe loaders require 15 liter of Automatic transmission fluid. Service intervals include a 10 hour check and a 1000 hour change. The data covers 2 configurations.

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

Additional Notes

  • The Hidromek Backhoe Loaders HMK 102B and HMK 102S share an identical powershift transmission fluid capacity of 15 liters, indicating a service fill volume rather than a full overhaul quantity.
  • A check interval of 10 hours applies to both configurations under normal use conditions, reflecting the relatively short monitoring cycle typical of powershift transmission systems in heavy equipment.
  • The change interval for both the HMK 102B and HMK 102S is set at 1000 hours under normal use conditions, which is a standard drain-and-refill cycle for powershift automatic transmission fluid in construction machinery.
  • Despite the HMK 102B using a John Deere 4045HF485 Tier 3 engine and the HMK 102S using a Perkins 1104D-44TA Tier 3 engine, the transmission fluid capacity and service intervals are identical across both models, pointing to a shared powertrain architecture on the transmission side.
