Unimog (MB) 403, 406, 413, 416

Clutch fluid capacity & service interval

Unimog (MB) 403, 406, 413, 416 models require 0,2 liter of clutch fluid. The service interval for fluid replacement is 12 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 hydraulic clutch system across the U 800 (403), U 800L (413), U 900 (406), and U 1100 (416) variants holds a capacity of 0.2 liter, which is a small reservoir volume consistent with a slave-cylinder-based hydraulic actuation circuit rather than a large fluid-filled transmission or brake system.
  • The 0.2 liter capacity figure applies uniformly across all listed configurations from 1970-1992, indicating no variation in reservoir size between the lighter 403/413 and the heavier 406/416 platform variants.
  • The specified change interval for clutch fluid across all rows is 12 months under normal use conditions, meaning annual replacement is the standard service cycle regardless of mileage or operating hours accumulated during that period.
  • The U 900 (406) and U 1100 (416) appear in two separate row entries, one covering 1970-1992 and another covering 1985-1992, both sharing identical capacity and interval specifications of 0.2 liter and a 12-month change cycle.
