ABSTRACT:
The power unit cart of the present invention provides for the quick, efficient, and easy replacement of either an engine or an electrical motor power unit as the power source for a cart-mounted spray painting pumping system. The power unit cart includes a main frame which has a partial tubular socket and an axial alignment member having a vertical support tab. The axial alignment member and the partial tubular socket pivotally and slidably engage a universal mounting base which includes a tubular member and an L-shaped bracket. The power unit is attached to the upper face of the universal mounting base. The axial alignment member and the partial tubular socket, in conjunction with an anchoring device, releasably and adjustably couple the universal mounting base and power unit to the power unit cart. The anchoring device is then attached to the L-shaped bracket for adjustment of the tension of a belt drive. The power unit cart also includes a belt housing having belt guides for positioning and holding of the belt drive in a desired location for convenient replacement of a power unit. The power unit cart additionally includes a pivotally-mounted, rearwardly-extending handle which may be easily manipulated in a forward direction to facilitate the replacement of a power unit.
