Tatra 815

Clutch fluid capacity & service interval

Tatra 815 uses clutch fluid with a capacity of 0,3 liter. The service interval for fluid change is 36 months. The data covers 3 configurations.

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

Additional Notes

  • The Tatra 815 T 815-2 260S25 TERRNo.1 variants — spanning the 3B-928-10, 3B-928-50, and 3B-928-60 configurations introduced from 1996 — all share an identical hydraulic clutch system fluid capacity of 0.3 liter.
  • A capacity of 0.3 liter is a relatively small reservoir volume, consistent with a hydraulic clutch circuit that serves actuation purposes rather than lubrication, meaning the fluid volume is contained within the master cylinder, lines, and slave cylinder assembly.
  • The 36-month change interval applies under normal use conditions across all three listed configurations, placing clutch fluid renewal on a time-based schedule rather than a mileage or operational-hours basis.
  • A 36-month interval for hydraulic clutch fluid reflects the general principle that brake and clutch fluids absorb moisture over time, degrading their boiling point and corrosion resistance regardless of how frequently the vehicle is operated.
  • The uniform specifications across the 3B-928-10, 3B-928-50, and 3B-928-60 variants indicate no differentiation in clutch fluid capacity or service interval among the three body or configuration designations within the T 815-2 260S25 TERRNo.1 family.
