Abstract
A wheel mounting system for a wet/dry vacuum cleaner is disclosed. A system provides a wet/dry vacuum cleaner base having a plurality of mounting surfaces extending therefrom. First and second wheels are mounted to first and second stub shafts which are inserted through at least two of the plurality of bearing surfaces and secured thereto using set screws. Flanges on outer ends of the stub shafts secure the wheels between the flanges and wheel wells extending from the base of the vacuum cleaner. A reinforcing shaft can be telescopingly received within the first and second stub shafts in order to enable the vacuum cleaner base to support relatively heavy loads.
