Komatsu Forklift trucks, electric - Tusk, ABX/BSX/CBX

Differential fluid capacity & service interval

Komatsu Forklift trucks, electric - Tusk, ABX/BSX/CBX use differential fluid with a capacity of 10 liters. Service intervals include checks every 3 months or 600 hours, and changes at 1 month or 200 hours and 6 months or 1200 hours. The data covers 12 configurations.

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

Additional Notes

  • The differential and transferbox are serviced as a combined system across all listed ABX series configurations, with a shared fluid capacity of 10 liters. This figure represents the total fill volume for both components together rather than each unit individually.
  • All six ABX configurations covered here, spanning the 300CB and 350CB model families with EH, SH, and SS variants, share identical differential fluid capacity and service interval specifications from serial number 85001A onward.
  • Under normal use conditions, the differential and transferbox fluid is subject to a check interval of every 3 months or 600 hours, whichever comes first. The change interval is set at 6 months or 1200 hours, again whichever is reached first. The dual time-and-hour structure accounts for machines that accumulate hours slowly as well as those used intensively.
  • An initial service condition applies to all listed configurations, requiring a fluid change at just 1 month or 200 hours of operation. This early change interval is standard practice for gear-type systems, as new components generate fine metallic particles during the break-in period that are removed by draining the fluid early.
  • The initial service change interval of 1 month or 200 hours is considerably shorter than the normal ongoing change interval of 6 months or 1200 hours, reflecting the elevated contamination risk during the early wear-in phase of the drivetrain.
  • No fluid capacity difference exists between the 300CB and 350CB model groups for the differential and transferbox system. Both groups are rated at 10 liters, indicating the same physical assembly is used across the two load capacity classes within the ABX series.
