Additional Notes
- The AdBlue (DEF) tank capacity across the LR626 Litronic and both LR636 configurations is 49 liters, which represents a substantial reservoir volume typical of heavy construction equipment designed for extended operation between refills.
- The Liebherr LR626 Litronic (serial number series 1327) paired with the D924-A7-04 engine carries a 49-liter AdBlue capacity under normal use conditions, with the engine series starting from unit 15905.
- Both LR636 variants, the standard (serial number series 1725) with the D934 engine from unit 20043 onward and the Litronic (serial number series 1275) with the D934-A7 engine from unit 12777 onward, share the same 49-liter AdBlue capacity under normal use conditions.
- All three configurations are equipped with a selective catalytic reduction (SCR) system, which is the emissions control technology that consumes AdBlue by injecting it into the exhaust stream to convert nitrogen oxides into nitrogen and water.
- The D924-A7-04 engine in the LR626 Litronic and the D934-series engines in the LR636 variants are distinct engine families, yet the identical 49-liter AdBlue tank capacity applies across all three pairings under normal operating conditions.
