Ingersoll Rand Compactors, SD series

Transfer case fluid capacity & service interval

Ingersoll Rand Compactors, SD series transfer case fluid capacity is 1,8 liters. Service intervals are 1000 hours or 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 SD-122D, SD-122DX, and SD-122F all share an identical transfer case fluid capacity of 1.8 liters, indicating a consistent transferbox design across these three variants of the Ingersoll Rand SD series compactors.
  • A 1.8-liter capacity is a relatively modest fill volume, consistent with a compact transfer case unit rather than a heavy-duty multi-range transfer assembly found in larger equipment.
  • The SD-122D carries a fluid change interval of 1,000 hours or 12 months under normal use conditions, meaning whichever threshold is reached first would typically trigger a service event.
  • The SD-122DX shares the same 1,000-hour or 12-month change interval as the SD-122D, alongside the same 1.8-liter capacity, suggesting the DX variant does not introduce any transfer case service differences despite its designation.
  • The SD-122F also follows the 1,000-hour or 12-month interval under normal use conditions, aligning fully with the other two variants in both capacity and service frequency.
  • A 1,000-hour service interval is a common benchmark in construction and compaction equipment, roughly corresponding to one full working season of moderate use, which is reflected in the parallel 12-month calendar-based threshold.
