Caterpillar Wheeled tool carriers

Differential fluid capacity & service interval

Caterpillar wheeled tool carriers use differential fluid with capacities ranging from 0,5 to 36 liters. Service intervals include checks at 1 month/250 hours or 3 months/500 hours, and changes at 12 months/2000 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 Caterpillar IT-62H and M5G wheeled tool carriers, introduced from 2007, share identical front and rear differential fluid capacities of 36 liters total per differential, indicating a substantial fluid volume consistent with heavy-duty axle assemblies on this class of equipment.
  • Alongside the 36-liter total fill, each differential also requires 0.5 liter of LS-additive, which is a limited-slip friction modifier blended into the fluid charge to support proper clutch pack behavior in limited-slip differentials.
  • The 0.5-liter LS-additive quantity applies equally to both the front and rear differentials across both normal and flexible fluid analysis service conditions, meaning the additive volume does not vary by service interval type.
  • Under normal use conditions, the front differential on the IT-62H and M5G calls for a fluid level check every 1 month or 250 hours, whichever comes first, with a full fluid change interval set at 12 months or 2000 hours.
  • The rear differential under normal use conditions carries the same check and change intervals as the front: a check at 1 month or 250 hours and a change at 12 months or 2000 hours, reflecting a symmetrical service schedule across both axles.
  • Under the flexible, fluid analysis use condition, the check interval for both the front and rear differentials extends to 3 months or 500 hours, which is three times the calendar interval and double the hour-based interval compared to normal use conditions.
  • No fluid change interval is listed under the flexible, fluid analysis condition for either differential, as that service approach relies on ongoing fluid sampling results rather than a fixed replacement schedule.
