Additional Notes

  • The Weidemann Telescopic loaders T4512 transfer box holds 0.3 liter of fluid, a small capacity consistent with a compact transfer case unit rather than a larger drivetrain assembly requiring a full overhaul fill.
  • Under normal use conditions, the T4512 with the Yanmar 3TNV82A engine calls for a transfer box fluid change at 1000 hours or 12 months, whichever comes first, following the standard dual-trigger interval format common in off-highway equipment maintenance schedules.
  • An initial service interval of 500 hours or 12 months applies to the T4512 Yanmar 3TNV82A transfer box, cutting the standard 1000-hour interval in half for the first change to clear any manufacturing residues or break-in contaminants from the fluid.
  • The T4512 fitted with the Yanmar 3TNV84T engine shares the same 0.3-liter transfer box capacity as the 3TNV82A variant, despite the 3TNV84T being a turbocharged unit producing 30 kW versus the naturally aspirated 3TNV82A at 23 kW.
  • The 3TNV84T-powered T4512 also carries the same initial service interval of 500 hours or 12 months for the transfer box, matching the pattern established for the lower-output engine configuration in the same model.
  • The T5522 with the Perkins 404F-22T engine, introduced from 2013, shares the 0.3-liter transfer box capacity with the T4512 configurations, placing all three engine variants at the same fill volume for the transfer case.
