JCB Wheeled excavators, JS-W
AdBlue (DEF) capacity & service interval
The JCB Wheeled excavators, JS-W use AdBlue (DEF) fluid with a capacity of 19 liters. The data covers 2 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.
| Type | Specifications |
|---|---|
| JS-110W Hydradig, JCB EcoMAX 444 TCA Stage IV/T4f (2018- ) |

Additional Notes
- The JCB JS-110W Hydradig carries a 19-liter AdBlue (DEF) tank capacity across both the Stage IIIB/T4i and Stage IV/T4f engine variants, meaning the physical reservoir size remained unchanged between emission standard generations.
- The 19-liter figure represents the total tank fill capacity of the selective catalytic reduction system, which is the volume of diesel exhaust fluid the SCR reservoir holds rather than a top-up or partial service quantity.
- The EcoMAX 444 TCA engine in Stage IIIB/T4i configuration, fitted to the JS-110W Hydradig from 2016-2018, uses the SCR system under normal use conditions with the 19-liter AdBlue capacity specification.
- The Stage IV/T4f variant of the EcoMAX 444 TCA, introduced from 2018 onward in the JS-110W Hydradig, retains the same 19-liter SCR tank capacity under normal use conditions as the earlier emission-tier engine.
- Stage IV and Stage IIIB/T4i represent progressively stricter exhaust emission standards, yet the AdBlue system capacity of 19 liters was not altered when the JS-110W Hydradig transitioned between these regulatory tiers.
