Weidemann Telescopic loaders

Differential fluid capacity & service interval

Weidemann telescopic loaders require differential fluid with a capacity of 2,5 liters. Service intervals consist of 500 hours or 12 months and 1000 hours or 12 months. The data covers 10 configurations.

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

Additional Notes

  • Both the front and rear differentials on the Weidemann Telescopic loaders T4512 with the Yanmar 3TNV82A engine each hold 2.5 liters of fluid, meaning the total differential system across both axles requires 5 liters at a full service fill.
  • The T4512 paired with the 23 kW Yanmar 3TNV82A carries an initial service interval of 500 hours or 12 months for both the front and rear differentials, which is half the standard normal-use interval and reflects the break-in period when metal components generate higher levels of wear particles in fresh fluid.
  • After the initial service, the normal-use change interval for both differentials on the 23 kW T4512 extends to 1,000 hours or 12 months, whichever comes first, applying equally to the front and rear units.
  • The T4512 fitted with the 30 kW Yanmar 3TNV84T engine shares the same 2.5-liter capacity per differential as the 23 kW variant, with identical initial service and normal-use intervals of 500 hours and 1,000 hours respectively, both subject to the 12-month time limit.
  • The front and rear differentials on the T4512 with the 30 kW Yanmar 3TNV84T follow the same dual-trigger interval structure as the 23 kW configuration, where the 12-month calendar limit applies regardless of whether the hour threshold has been reached.
  • The T5522 with the Perkins 404F-22T engine, introduced from 2013, also specifies 2.5 liters per differential for both the front and rear units under normal use, placing fluid capacity on par with the T4512 configurations.
