Cheng Gong Wheeled loaders
Differential fluid capacity & service interval
Cheng Gong wheeled loaders require differential fluid with capacities ranging from 26 to 40 liters plus hub reductions. Service intervals include checking every 3 months or 500 hours, and changing every 50 hours, 500 hours or 3 months, or 12 months or 2000 hours. The data covers 24 configurations.

Additional Notes
- The Cheng Gong CG935G Wheeled Loader, fitted with the Cummins QSB5.9 engine, carries a front and rear differential fluid capacity of 26 liters each, with the notation that hub reductions hold additional fluid volume beyond that figure.
- The CG938H, CG958G, and CG958H models, all paired with the Cummins QSB6.7 engine, share a front and rear differential capacity of 40 liters each, plus hub reductions, which is notably higher than the 26-liter figure on the QSB5.9-powered CG935G.
- Across all four models, the first-change-only interval for both front and rear differentials is set at 50 hours. A first change at such a low hour mark is associated with the removal of break-in contaminants, including metal particles generated during initial component wear-in.
- During the initial 1,500 operating hours, all models specify a differential fluid change interval of 500 hours or 3 months, whichever comes first. This more frequent cadence reflects the elevated wear rates typical of newly commissioned drivetrain components.
- Under normal use conditions, the differential fluid check interval for all listed models is every 3 months or 500 hours, while the full change interval extends to 12 months or 2,000 hours. The dual time-and-hour structure means whichever threshold is reached first governs the service event.
- The front and rear differentials on each model share identical capacity and interval specifications, indicating a symmetrical axle design with no differentiation in fluid volume or service timing between the two axles.
