Additional Notes
- The AL 6B and AL 7 share an identical cooling system capacity of 12 liters under normal use conditions, despite belonging to different model designations within the Ahlmann Wheeled Loaders AL range.
- The AL 7D carries a notably smaller cooling system capacity of 7.6 liters under normal use conditions, a reduction of more than 4 liters compared to the 12-liter figure associated with the AL 6B and AL 7.
- All three configurations list capacity figures tied to normal use conditions, meaning the 12-liter and 7.6-liter values reflect standard operating environments rather than severe-duty cycles.
- The AL 6B, covering model years 1985-1993, holds the longest production span among the three configurations and maintains the 12-liter cooling system capacity throughout that entire period.
- The AL 7D, introduced in 1991, represents a later generation within the lineup and carries the distinct 7.6-liter cooling system specification that sets it apart from the earlier AL 7 despite the similarity in model designation.
