Additional Notes

  • The Unimog (MB) 421 U 600 and U 600 L run a hydraulic clutch system, with a fluid capacity of 0.2 liter recorded for normal use conditions.
  • A 0.2 liter capacity is characteristic of a small hydraulic actuator circuit, consistent with a master cylinder and slave cylinder arrangement rather than a large reservoir-fed system.
  • The service interval for the clutch fluid is set at 12 months under normal use conditions, meaning the fluid is replaced on an annual calendar basis regardless of mileage or operating hours accumulated in that period.
  • The same 0.2 liter capacity and 12-month change interval apply uniformly across the 1970-1992 production span covered by the U 600 and U 600 L variants, with no differentiation recorded between the two body configurations.
