Manitou Maniscopic, BTI

Transfer case fluid capacity & service interval

Manitou Maniscopic and BTI models utilize transfer case fluid with a capacity of 0,4 liter. The service interval for fluid changes is 800 hours. The data covers 2 configurations.

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

Additional Notes

  • The BTI 220 Series 2 and BTI 225 Series 2 each carry a transfer case (transferbox) fluid capacity of 0.4 liter, a figure consistent with compact transfer assemblies where the internal gear and bearing volume is minimal.
  • A 0.4-liter fill is characteristic of a service fill quantity rather than an overhaul or full-drain specification, reflecting the small sump volume typical of this class of transfer unit.
  • The fluid change interval for both the BTI 220 Series 2 and BTI 225 Series 2 is set at 800 hours under normal use conditions, meaning the interval applies to standard operating environments rather than elevated-stress or severe-duty cycles.
  • The BTI 220 Series 2 and BTI 225 Series 2 share identical transfer case fluid specifications across both capacity and change interval, indicating no differentiation in the transfer assembly between the two models in Series 2 configuration.
