Additional Notes

  • Across the Gallmac WMW series (2008-2010), differential fluid capacity is specified uniformly at 11.5 units per axle, applying equally to both front and rear differentials in every listed configuration.
  • The WMW 100L, WMW 100LT, and WMW 115 variants, all powered by the Perkins 1104D-44T engine, express differential capacity in liters (11.5 L), while the WMW 150 configurations express the same numerical value in kilograms (11.5 kg), reflecting a unit-of-measure difference between the Perkins-engined and WMW 150 models.
  • Capacity measured in kilograms rather than liters is a weight-based fill specification. For gear oils, which have a density slightly above 0.85–0.90 kg/L depending on viscosity grade, a kilogram-based figure results in a slightly lower actual volume than the same number expressed in liters.
  • The WMW 150 is listed with two distinct engine options for the 2008-2010 period: the Deutz BF4M2012C and the John Deere 4045 HF285. Both share identical front and rear differential capacities of 11.5 kg, indicating the differential assembly is common across engine variants within the WMW 150.
  • All differential fluid specifications across the WMW series are designated for normal use conditions, meaning the stated 11.5-unit capacity applies to standard operating environments rather than severe-duty cycles.
  • The symmetry between front and rear differential capacities at 11.5 units across all WMW configurations suggests a common axle assembly is used at both ends of the machine within each model line.
  • The WMW 100L and WMW 100LT share the same Perkins 1104D-44T engine and identical front and rear differential capacities, with the "T" suffix in the 100LT designation representing a variant distinction that does not affect the differential fluid specification.
