Additional Notes

  • All four models in the Tusk CX50 series covered here — the 800PD-10, 900PD-10, 1000PD-10, and 1100PD-10 — share an identical front differential fluid capacity of 10 liters, each paired with the Komatsu SAA4D95LE-5-A engine.
  • The 10-liter figure represents a service fill capacity for the front differential, meaning the volume required when refilling during routine maintenance rather than a full overhaul rebuild quantity.
  • Under normal use conditions, the front differential fluid check interval is set at 3 months or 600 hours, whichever comes first, with a full fluid change due at 6 months or 1,200 hours.
  • The dual-trigger interval structure — combining a calendar period with an operating hour threshold — accounts for machines that accumulate hours quickly as well as those used less frequently, ensuring neither time nor wear is the sole determining factor.
  • An initial service change is specified at 1 month or 200 hours across all four models. Early fluid changes at this interval allow metal particles and contaminants generated during component break-in to be removed before they cause accelerated wear.
  • The initial service change interval of 1 month or 200 hours is considerably shorter than the normal change interval of 6 months or 1,200 hours, reflecting the elevated contamination load typical of newly commissioned drivetrain components.
  • No variation in front differential fluid capacity or service intervals exists across the 800PD-10, 900PD-10, 1000PD-10, and 1100PD-10 configurations, despite the differences in model designation that typically correspond to varying load capacities within a series.
