Hürlimann XB T-TB COM3
Differential fluid capacity & service interval
Hürlimann XB T-TB COM3 differential fluid capacity is 6 liters. Service intervals include checking every 250 hours and changing every 1000 hours or 24 months. The data covers 8 configurations.

Additional Notes
- The Hürlimann XB T-TB COM3 front differential holds 6 liters across all listed variants, covering the XB 85 T, XB 85 TB, XB 100 T, and XB 100 TB configurations from 2010-2016. A uniform capacity across all eight rows indicates a shared front differential housing regardless of power rating or cab designation.
- Each variant is split into two serial number bands: units up to serial 1001 and units from serial 1002 to 5001. Despite this production-sequence distinction, the front differential fluid capacity and service intervals are identical across both bands for every model in the range.
- The fluid level check interval is set at 250 hours under normal use conditions. In agricultural equipment, a 250-hour check interval is a relatively frequent inspection point, reflecting the mechanical stress placed on front differentials in field operation.
- The fluid change interval is specified at 1000 hours or 24 months, whichever comes first, under normal use conditions. The dual-trigger format means a tractor used lightly enough to reach 24 months before accumulating 1000 hours would still require a fluid change at the calendar threshold.
- The 1000-hour change interval means that on a tractor averaging 500 operating hours per year, a front differential fluid change would fall due approximately every two years, aligning closely with the 24-month calendar limit specified alongside it.
- The T and TB designations within the XB range refer to cab configurations, yet the front differential fluid capacity of 6 liters and the associated service intervals remain unchanged between the two. This indicates the cab type has no bearing on the front axle differential specification.
