JCB Articulated dump trucks

Coolant capacity & service interval

JCB Articulated dump trucks require coolant with a capacity range of 27 to 33 liters. Service intervals include checks at 10 hours and changes at 2000 hours or 24 months. The data covers 5 configurations.

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

Additional Notes

  • The JCB 718 fitted with the Cummins 6BTAA5.9 engine carries the largest cooling system capacity across all listed configurations at 33 liters, compared to 30 liters for the 714 with the same engine family.
  • When the 718 transitioned from the Cummins 6BTAA5.9 to the QSB6.7 from serial number 1304600 onward in 2011, cooling system capacity decreased from 33 liters to 30 liters despite the engine displacement remaining at 6.7 liters in the newer unit.
  • The 722 with the Cummins QSB6.7 carries a 27-liter cooling system capacity, the lowest among all listed configurations, even though all three QSB6.7-equipped models share the same engine platform.
  • Cooling system change intervals for the 714 with the Cummins 6BTAA5.9 are specified at 2000 hours under normal use conditions, with no periodic check interval listed alongside that figure.
  • All three QSB6.7-equipped models share a 10-hour check interval for the cooling system under normal use conditions, a short-cycle inspection tied to early operational monitoring rather than fluid replacement.
  • The QSB6.7-equipped configurations across the 714, 718, and 722 all carry a dual-condition change interval of 2000 hours or 24 months, whichever occurs first under normal use. The time-based threshold of 24 months accounts for machines that accumulate low hours over extended calendar periods.
  • The 714 with the Cummins 6BTAA5.9, covering model years 2000-2010, specifies only a 2000-hour change interval with no calendar-based alternative, a simpler interval structure than the QSB6.7 generation that followed from 2011.
