Additional Notes
- Both the U 1300 and U 1700 variants of the Mercedes-Benz Unimog 435 share an identical power steering fluid capacity of 3.25 liters, covering the full 1985-1992 production span for each.
- A 3.25-liter capacity in a power steering system is relatively substantial, reflecting the heavy-duty hydraulic assist demands typical of a multi-purpose off-road vehicle platform like the Unimog 435.
- The service interval for power steering fluid is specified at 2,400 hours or 24 months under normal use conditions, whichever comes first, applying equally to both the U 1300 and U 1700 configurations.
- An hour-based interval of 2,400 hours is characteristic of commercial and agricultural machinery servicing, where engine runtime is a more reliable measure of wear than distance traveled.
- The dual-format interval of 2,400 hours and 24 months means that calendar time alone triggers a fluid change even when operational hours remain low, preventing fluid degradation from extended storage or infrequent use.
