Additional Notes

  • The front differential capacity across all JCB Fastrac 2000 Series models covered in these specifications holds a uniform 7 liters, regardless of model variant, engine fitment, or production year. This consistency across the 2115, 2125, 2135, 2140, 2150, 2155, and 2170 suggests a shared front axle assembly throughout the series.
  • Rear differential capacity varies depending on steering configuration. A 2-wheel steer (2WS) rear differential holds 23 liters, while the 4-wheel steer (4WS) variant holds 17 liters. The 6-liter difference reflects the additional mechanical components housed within the 4WS rear axle assembly, which reduce the available fluid volume.
  • For the Perkins 1006-6T and Cummins QSB5.9 30 powered models produced from 1998-2006, the routine differential fluid check interval is set at 250 hours under normal use conditions. The change interval is 1000 hours or 12 months, whichever comes first.
  • The 2007-2014 Fastrac 2155 and 2170 models carry a notably shorter check interval of 100 hours for both front and rear differentials under normal use, compared to the 250-hour check interval specified for the earlier 1998-2006 models. The change interval of 1000 hours or 12 months remains the same across both generations.
  • The Fastrac 2155 and 2170 (2007-2014) introduce a first change only interval of 100 hours for both front and rear differentials. A first-change interval at 100 hours is a break-in service procedure, intended to remove metal particles and contaminants generated during the initial wear-in period of new gear surfaces.
  • The Fastrac 2140, fitted with the Cummins QSB5.9 30 engine, covers a narrower production window of 2004-2006 compared to the Perkins 1006-6T variants of the 2115, 2125, 2135, and 2150, which span 1998-2006. Despite the different engine, the differential fluid capacities and service intervals for the 2140 are identical to the other Perkins-powered models in the same serial number range.
  • All models in these specifications carrying serial numbers from 0738000 onward share the same differential fluid capacities and service intervals within their respective production periods. The serial number threshold indicates a production cut-off point below which these specifications may not apply.
  • The dual-interval structure for the 2007-2014 models, combining a first change only at 100 hours with a subsequent normal change interval at 1000 hours or 12 months, means the total number of fluid changes over a given service life is higher for the 2155 and 2170 than the interval figures alone might suggest when viewed in isolation.
