Komatsu Telehandlers, LW/WH

Differential fluid capacity & service interval

Komatsu Telehandlers, LW/WH utilize differential fluid with a capacity range of 7,1 to 35 liters. Service intervals include checks every 3 months or 250 hours, and fluid changes every 1000 hours or 12 months, and every 2000 hours. The data covers 12 configurations.

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

Additional Notes

  • The Komatsu LW250-5 carries a differential fluid capacity of 35 liters per axle, a figure substantially larger than the 7.1-liter capacity shared across the WH-series models. A 35-liter differential housing is characteristic of heavier-duty axle assemblies designed for higher load ratings.
  • Front and rear differential capacities are identical within each model. On the LW250-5, both axles hold 35 liters, while on all listed WH-series models, both axles hold 7.1 liters, indicating symmetrical axle configurations across the range.
  • The LW250-5 specifies a change interval of 2000 hours under normal use conditions, with no separate check interval listed. The 2000-hour mark is a relatively extended drain interval, more commonly associated with heavy construction equipment operating in controlled duty cycles.
  • All WH-series models from 2004-2009, including the WH609, WH613, WH713, WH714, and WH716, share a dual-stage service schedule: a fluid level check every 3 months or 250 hours, and a full fluid change every 12 months or 1000 hours, whichever comes first under normal use conditions.
  • The 250-hour or 3-month check interval on the WH-series differentials serves as an intermediate inspection point between full drain cycles. At 7.1 liters per differential, even minor fluid loss between changes can represent a meaningful percentage of total fill volume.
  • The WH714 is specified for the 2004-2006 period, a narrower range than the 2004-2009 span covering the WH609, WH613, WH713, and WH716. Despite the shorter production window, the WH714 shares the same 7.1-liter capacity and 1000-hour change interval as the other WH models.
  • The 1000-hour change interval on WH-series differentials, combined with the 12-month calendar limit, means that machines with lower annual utilization would reach the service point based on elapsed time rather than operational hours.
