Amkodor Forklifters

Automatic transmission fluid capacity & service interval

Amkodor Forklifters use automatic transmission fluid with a capacity of 30 liters. Service intervals include checks at 250 hours and changes at 125, 500, and 1000 hours. The data covers 6 configurations.

Additional Notes

  • The Amkodor Forklifters 451A hydromechanical transmission holds 30 liters of automatic transmission fluid across both the 60 kW MMZ D-243 and 74 kW MMZ D-245 engine configurations, with no difference in fluid capacity between the two variants.
  • A 30-liter fill is a substantial volume, consistent with a hydromechanical transmission system that integrates a torque converter and hydraulic circuitry, requiring a larger fluid reservoir than a conventional geared unit.
  • Under normal use conditions, the fluid level on both 451A configurations is checked every 250 hours, while a full fluid change is performed at 1,000-hour intervals.
  • The initial service interval on both 451A variants calls for a fluid change at 125 hours, which is significantly earlier than the 1,000-hour normal change interval, reflecting the break-in period during which new transmission components shed metallic particles into the fluid.
  • A second change only interval of 500 hours is specified for both 451A configurations, placing a mandatory fluid change at the midpoint between the initial service and the first full normal-cycle change, before the standard 1,000-hour rhythm takes effect.
  • The three-stage service sequence across the 451A — initial change at 125 hours, second change at 500 hours, then normal changes at 1,000-hour intervals — represents a progressively lengthening schedule as the transmission matures through its early operational life.
  • The identical capacity and interval specifications across the 60 kW D-243 and 74 kW D-245 engine variants of the 451A indicate that both share the same hydromechanical transmission assembly, despite the difference in engine output.
