Lonking Wheeled loaders

Differential fluid capacity & service interval

Lonking wheeled loaders utilize differential fluid with capacities ranging from 18,5 to 31 liters plus hub reductions. Service intervals include checks at 50 hours and changes at 500 hours or 12 months. The data covers 8 configurations.

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

Additional Notes

  • The Lonking CDM835-EHIII carries 18.5 liters of differential fluid in each axle, front and rear, with the notation that hub reductions hold additional fluid volume beyond that figure. The 18.5-liter value therefore represents the differential housing alone, not the total axle fill.
  • The CDM858-I, CDM858-NGH, and CDM858-NH all share a 31-liter differential capacity per axle, front and rear, again exclusive of hub reduction volumes. The larger capacity relative to the CDM835-EHIII reflects the heavier-duty axle assemblies fitted to the higher-output 858-series machines.
  • Hub reductions are separate gear sets mounted at each wheel end that multiply torque from the differential. Because fluid in those housings is not included in the listed capacities, a complete axle service on any of these models requires accounting for hub reduction fill volumes in addition to the differential figures shown.
  • Across all listed configurations, the differential fluid check interval is set at 50 hours of operation under normal use conditions. A 50-hour interval is a short cycle by heavy equipment standards and reflects the need to detect early fluid contamination or level loss before significant wear occurs.
  • The change interval for differential fluid on all listed models is 500 hours or 12 months under normal use conditions, whichever comes first. The dual trigger means calendar time governs service even when a machine accumulates hours slowly, since fluid degrades through oxidation and moisture absorption regardless of use.
  • All eight rows carry a normal use condition designation. In heavy equipment service, normal use typically describes operation within the machine's rated load and duty cycle, as opposed to severe conditions such as continuous heavy loading, extreme temperatures, or highly abrasive environments.
  • The front and rear differentials on each model share identical capacity and interval specifications. On articulated wheeled loaders, both axles are driven and carry comparable loads, which accounts for the symmetry in service requirements between the front and rear units.
  • The CDM858-I, CDM858-NGH, and CDM858-NH are all powered by the Cummins QSB6.7-C220 Tier 3 engine and share the same 31-liter differential specification, indicating the axle assembly is common across those three variants despite their differing model suffixes.
