Abstract: In the operation of modern day construction machinery, especially those of relatively large size, it is a common occurrence for the bearings in the axle assemblies to wear during the normal course of operation of the machine. As the wear occurs, minute particles become suspended in the fluid circulated within the axle assembly. As the particulate matter increases the wear is also accelerated and failure of one or more components in the axle assembly will frequently occur. The present invention provides an axle assembly with a filter and a cooler and flow control valve to remove the particulate matter and reduce the heat from the fluid circulated within the axle assembly.

Abstract: A vehicle wheel is mounted on spaced apart portions of the vehicle frame. A template is mounted on the frame for aligning an alignment sleeve in the frame. The sleeve is secured on the frame in its aligned position. The template is removed and the wheel is mounted on the frame.

Abstract: A modular truck body comprises a pair of upstanding side modules each having an L-shaped cross section, a bottom module having its outer edges secured to inner edges of the side modules and an upstanding front module secured between the side modules and having its lower edge secured to the bottom module. The modules are aligned and pre-assembled at a manufacturing plant and then disassembled for shipping purposes. At a customer's job site or the like the modules are re-assembled and secured together for installation on the frame of a truck.
