Renault Celtis

Differential fluid capacity & service interval

Renault Celtis differential fluid capacity ranges from 5,5 to 6 liters. Service intervals include checks at 100 hours and changes at 1000 hours. The data covers 4 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Renault Celtis 426, 436, and 446 variants all share a front differential fluid capacity of 5.5 liters, while the Celtis 456 carries a slightly larger 6-liter capacity in the same location.
  • The 0.5-liter difference between the 456 and the three lower variants reflects a physically larger front differential housing on the top-tier model, which is a common engineering characteristic in tractors with higher torque outputs.
  • All four Celtis variants specify a front differential fluid check interval of every 100 operating hours under normal use conditions, indicating a relatively frequent monitoring schedule relative to the change interval.
  • The fluid change interval across all four variants is set at 1,000 operating hours under normal use conditions, meaning a single change cycle spans ten times the length of the check interval.
  • Operating hours rather than calendar time govern both the check and change intervals for all listed configurations, which is standard practice for agricultural machinery where annual usage varies considerably between operators.
  • The model designations for the Celtis 426, 436, and 446 each include three internal codes (e.g., M3612DB, 3612DA, 3611DB), whereas the Celtis 456 lists only two (M3642DB, 3642DA), though the fluid specifications remain consistent within each respective variant regardless of internal code.
