A system including a DEF tank and a fuel tank arranged in a portion of a vehicle to give that portion multiple structural functions. The system may be arranged to form a part of a counterweight on a work vehicle.
Claims20
A combined DEF and fuel fill assembly, comprising:
- a counterweight having a housing defining a DEF tank containment area and a fill area partitioned by a separator wall into a DEF fill area and a fuel fill area, the housing defining an opening at an upper region of the fill area for simultaneously accessing both the DEF fill area and the fuel fill area;
- a DEF tank housed in the DEF tank containment area of the counterweight;
- a DEF filler tube disposed within the DEF fill area and in communication with the DEF tank;
- a fuel filler tube disposed within the fuel fill area and in communication with a fuel tank;
- a spill guard disposed within the DEF fill area, the spill guard having a bottom and upright walls configured to couple to the housing and the separator wall to inhibit DEF from passing into the fuel fill area, the bottom having an opening through which the DEF filler tube extends such that the bottom of the spill guard is positioned below the fill end of the DEF filler tube and an upper edge of the separator wall;
- and
- an attachment collar disposed about the DEF filler tube and configured to couple the DEF filler tube to the spill guard,
- wherein the spill guard includes a drain for routing DEF away from the DEF fill area.
