Manitou Forklift trucks, S-TC

Differential fluid capacity & service interval

Manitou Forklift trucks, S-TC differential fluid capacity ranges from 5,5 to 45,9 liters. Service intervals require changes every 1200 hours. The data covers 9 configurations.

Additional Notes

  • The front differential fluid capacity across all Manitou S-TC forklift truck variants listed — S402TC-D, S404TC-D, S502TC-D, S504TC-D, S602TC-D, and S604TC-D — is uniformly 45.9 liters. A capacity at this scale is characteristic of a drive axle housing that integrates the differential, final drive reduction gearing, and wheel end assemblies into a single shared oil bath, rather than a conventional passenger vehicle differential.
  • The rear differential fluid capacity on the S404TC-D, S504TC-D, and S604TC-D models is 5.5 liters, a figure more consistent with a conventional standalone differential housing. The substantial difference between the 45.9-liter front and 5.5-liter rear capacities reflects fundamentally different axle architectures between the two ends of these machines.
  • Only the S404TC-D, S504TC-D, and S604TC-D variants carry rear differential specifications. The S402TC-D, S502TC-D, and S602TC-D models have no rear differential entry, which corresponds to the "2" suffix in those model designations, commonly indicating a two-wheel-drive configuration in Manitou's S-TC nomenclature, while the "4" suffix indicates four-wheel drive.
  • All differential fluid change intervals across every listed variant are set at 1200 hours under normal use conditions. In industrial forklift applications, hour-based service intervals are standard practice, as operating hours provide a more consistent measure of mechanical wear than calendar time or distance.
  • The 1200-hour change interval applies uniformly to both the front and rear differentials on four-wheel-drive models, meaning both axles share the same service schedule despite their differing fluid capacities and housing designs.
  • All nine rows carry a normal use condition designation. In heavy equipment service classifications, normal use typically refers to operation within the manufacturer's standard duty cycle parameters, as opposed to severe use, which would involve extreme temperatures, heavy contamination exposure, or continuous maximum-load operation.
  • All listed variants are powered by the Ford 192 ci engine, a 3.1-liter inline-four diesel engine used across the S-TC range. The consistent engine specification across the S402TC-D through S604TC-D models means drivetrain loading characteristics are comparable across variants, which aligns with the uniform differential service intervals.
