Redrock Telehandlers, TH

Transfer case fluid capacity & service interval

Redrock Telehandlers, TH models require transfer case fluid with a capacity of 1 liter. The data covers 4 configurations.

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

TypeSpecifications

  • Use: Normal
  • Capacity 1 liter
TH280, Iveco 4.5 Tier 3 (2003-2006)
  • Use: Normal
  • Capacity 1 liter
TH280S, Iveco 4.5 Tier 3 (2003-2009)
  • Use: Normal
  • Capacity 1 liter
TH300, Perkins 1004.4T (1999-2004)
  • Use: Normal
  • Capacity 1 liter

Additional Notes

  • Across all four Redrock TH telehandler configurations listed, the transfer case (referred to in the specifications as the transferbox) holds a capacity of 1 liter. A 1-liter figure is characteristic of a compact transfer case unit, consistent with the relatively light-duty power transfer demands of a telehandler drivetrain compared to heavier off-highway equipment.
  • The TH280 with the Iveco 4.5 Tier 3 engine covers model years 2003-2006, while the TH280S with the same engine family spans 2003-2009. Both share the 1-liter transferbox capacity, meaning the "S" variant introduced no change to transfer case volume despite representing a distinct model designation.
  • The TH300 paired with the Perkins 1004.4T engine covers 1999-2004, making it the earliest configuration in the listed specifications. The Perkins 1004.4T is a turbocharged four-cylinder diesel, and the transferbox capacity of 1 liter applies under normal use conditions for that pairing.
  • The TH320 with the Iveco 4.5 Tier 3 engine has a starting year of 2009, placing it as the most recent configuration in the listed data. The transferbox capacity remains 1 liter under normal use conditions, consistent with the other Iveco-engined variants in the lineup.
  • All four configurations carry a normal use condition designation for the transferbox specification. In fluid service contexts, a normal use condition typically reflects standard operating cycles without the added stress factors, such as sustained heavy loads or extreme temperatures, that would otherwise trigger a severe-use interval.
