Hürlimann XF SPIRIT
Brake fluid capacity & service interval
Hürlimann XF SPIRIT uses brake fluid with a capacity of 1 liter. Service intervals require a check every 50 hours. The data covers 3 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.
| Type | Specifications |
|---|---|
| XF 70 Spirit, Stage 3B ->ZKDEZ10200RH50001 (2018- ) |
|
| XF 80 Spirit, Stage 3B ->ZKDEZ50200RH50001 (2018- ) |
|
| XF 80.4 Spirit, Stage 3B ->ZKDEZ90200RH50001 (2018- ) |

Additional Notes
- The Hürlimann XF Spirit brake fluid capacity is listed at 1 liter across the XF 70 Spirit, XF 80 Spirit, and XF 80.4 Spirit configurations, each referencing the hydraulic brake system specifically.
- A 1-liter capacity figure for a hydraulic brake system on agricultural tractors of this class is consistent with a service fill volume rather than a full system overhaul quantity, which would typically account for reservoir, lines, and actuator displacement combined.
- The check interval for brake fluid is set at 50 hours across all three Stage 3B variants, a relatively short interval by tractor service standards, reflecting the safety-critical nature of hydraulic brake circuits under working conditions.
- The 50-hour check interval applies under normal use conditions, meaning the specification does not account for any reduction or extension of that interval under severe or light-duty operating scenarios.
- All three variants share an identical capacity and check interval, indicating no differentiation in brake system specification between the XF 70 Spirit, XF 80 Spirit, and XF 80.4 Spirit despite their differing power outputs.
- Each variant carries a sequential serial number threshold in the format ZKDEZ_0200RH50001, marking the production point from which the 2018-onward specifications apply, with the XF 70 Spirit beginning at ZKDEZ10200RH50001, the XF 80 Spirit at ZKDEZ50200RH50001, and the XF 80.4 Spirit at ZKDEZ90200RH50001.
