Hyster Forklift trucks, petrol/LPG

Manual transmission fluid capacity & service interval

Hyster Forklift trucks, petrol/LPG require manual transmission fluid with a capacity of 3.3 liters. Service intervals include checking every 6 months or 1000 hours and changing every 12 months or 2000 hours. The data covers 6 configurations.

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

Additional Notes

  • All six Hyster forklift configurations listed here share an identical manual transmission fluid capacity of 3.3 liters, which represents the service fill volume used during routine fluid changes rather than a full overhaul or dry-fill quantity.
  • The check interval across every listed configuration is set at 6 months or 1,000 hours, whichever comes first. In forklift applications, hour-based intervals are often the more relevant trigger, since industrial equipment can accumulate operating hours far faster than calendar time would suggest.
  • The fluid change interval is set at 12 months or 2,000 hours for all configurations. The dual-trigger format means a unit reaching 2,000 hours before the 12-month mark would still require a fluid change at that point.
  • All specifications apply under normal use conditions. In forklift service, normal use typically refers to standard indoor or moderate-duty operation, as opposed to severe conditions such as extreme temperatures, heavy continuous loads, or highly contaminated environments.
  • The H3.50XL, H4.00XL, H4.50XL, and H5.00XL models with the GM 4.3L V6 engine share the same 3.3-liter capacity and service intervals, and all carry a 1996-1999 production span within these specifications.
  • The H6.00XL and H7.00XL models with the GM 4.3L V6 engine carry a longer production span of 1996-2008 while retaining the same 3.3-liter capacity and identical check and change intervals as the earlier XL-series configurations.
