Werklust Wheeled loaders, WG

Brake fluid capacity & service interval

Werklust wheeled loaders, WG, require brake fluid with a capacity of 3 liter. The service interval for fluid replacement is 2400 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 Werklust WG wheeled loaders use a hydraulic brake system, meaning brake fluid serves as the pressure-transmitting medium in the braking circuit rather than acting solely as a corrosion inhibitor or lubricant as in conventional reservoir-fed systems.
  • A 3-liter brake fluid capacity applies uniformly across the WG 18C, WG 35B, WG 35C, and WG 35D variants, indicating a consistent hydraulic brake circuit volume regardless of engine fitment or loader size designation.
  • The WG 18C with Cummins 6BT 5.9-C engine, the WG 35C with Cummins 6BTA 5.9-C, and the WG 35D with Cummins 6BT 5.9-C all share a brake fluid change interval of 2400 hours under normal use conditions. In heavy equipment, hour-based intervals reflect operating time rather than calendar periods, which is standard practice for machines that may run continuously across shifts.
  • The WG 35B fitted with the DAF DNT-620A engine carries the same 3-liter brake fluid capacity as the other WG variants but has no change interval listed in the specifications, distinguishing it from the three Cummins-engined models.
  • The 2400-hour change interval on the Cummins-engined models applies specifically to normal use conditions. In heavy equipment classification, normal use typically refers to standard loading cycles and operating environments, as opposed to severe conditions such as extreme dust, temperature, or continuous maximum-load operation.
