Additional Notes

  • The Volvo FM-10 (EU) rear hypoid differential carries 18.5 liters of fluid, a figure typical of heavy-duty truck axle assemblies where larger oil volumes are needed to maintain adequate lubrication across wide gear contact surfaces under load.
  • Both the FM10-360 in 4x2 and 6x2 axle configurations share an identical rear differential capacity of 18.5 liters, meaning the drivetrain layout does not alter the per-axle fluid requirement for the rear hypoid unit.
  • The capacity values listed for both configurations apply under normal use conditions, which in heavy vehicle service contexts generally refers to standard on-road operation as opposed to severe-duty or off-road cycles.
  • A rear hypoid differential of the type fitted to the FM10-360 uses a hypoid gear set, where the pinion centerline sits below the ring gear centerline. Fluid fill levels in such units are calibrated to ensure the lower-positioned pinion remains properly lubricated, which contributes to the relatively high 18.5-liter capacity figure.
