Lonking Wheeled loaders

Automatic transmission fluid capacity & service interval

Lonking wheeled loaders utilize automatic transmission fluid with a capacity range of 36 to 50 liters. Service intervals include checking every 10 hours and changing every 3 months or 500 hours. The data covers 4 configurations.

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

Additional Notes

  • The Lonking CDM835-EHIII carries a powershift transmission fluid capacity of 36 liters, which is notably lower than the 50-liter capacity shared by the CDM858-series models, reflecting the difference in machine size and transmission scale between the two loader classes.
  • The CDM858-I, CDM858-NGH, and CDM858-NH all share an identical 50-liter powershift transmission fluid capacity, indicating a common transmission assembly across those three configurations despite their differing model designations.
  • All four configurations specify a fluid level check interval of every 10 hours, which is a very short interval consistent with break-in monitoring or daily pre-shift inspection practices on heavy construction equipment.
  • The fluid change interval across all four configurations is set at 3 months or 500 hours under normal use conditions, whichever comes first. The dual-trigger format accounts for machines that accumulate calendar time without reaching the hour threshold, ensuring fluid degradation from oxidation and contamination is still addressed.
  • A powershift transmission, as noted for all four configurations, uses a hydraulically actuated multi-plate clutch system that places high thermal and shear demands on the fluid, which is why dedicated automatic transmission fluid rather than general hydraulic oil is specified for these systems.
  • The Cummins QSB6.7 engine platform is shared across all four configurations, appearing in both the C133 and C220 power ratings. The transmission fluid specifications vary between the CDM835-EHIII and the CDM858-series, indicating that engine commonality does not necessarily produce identical drivetrain fluid requirements.
