Lindner Unitrac
Power steering fluid capacity & service interval
Lindner Unitrac power steering fluid capacity is 20-28 liters. Service intervals include checking every 250 hours and changing every 1000 hours. The data covers 3 configurations.

Additional Notes
- The Lindner Unitrac power steering function is integrated into the hydraulic system rather than served by a dedicated standalone reservoir, which means the capacity figures reflect the shared hydraulic circuit.
- All three variants — the Unitrac 68, 78, and 95 — carry an identical capacity range of 20-28 liters for the combined hydraulic and power steering system.
- The 20-28 liter range, rather than a fixed single value, indicates a service fill tolerance, accounting for variables such as cylinder position and circuit state at the time of filling.
- A check interval of 250 hours applies uniformly across the Unitrac 68, 78, and 95, meaning the fluid level is inspected well before a full drain and refill is due.
- The change interval is set at 1000 hours for all three variants, representing four full check cycles before a complete fluid exchange is required.
- All specifications are rated for normal use conditions, meaning the 250-hour check and 1000-hour change intervals are not adjusted for any alternative operating severity in the data provided.
- The Unitrac 68, 78, and 95 share identical capacity, check, and change specifications despite representing different model designations, suggesting a common hydraulic architecture across the 2004-onward lineup.
