Devices have been used to compensate for misalignment between adjacent members and establish subsequent aligned assembly. These devices used tight tolerance, compound eccentric bushings or offset frusto-conical surface in attempting to provide a fixed aligned position. These devices are expensive and difficult to align. The subject bolt-on dowel provides a simple inexpensive solution to positioning of a first member relative to a second member. The bolt-on dowel includes a cylindrical spacer slidably fitted within a bore of the first member with the first end being in abutment with the second member, and a fastening member securing the spacer to the second member in a fixed position.

A deaerator device has a tubular casing and an internal helical blade defines an axial opening through the center thereof toward which entrained gas bubbles will converge as a fluid travels through the casing. A vent pipe collects the gas bubbles at the opening and communicates them away from the casing.

A receptacle is provided to receive and reinforce an engine fluid cooling radiator core. The core is secured within the receptacle and mounted adjacent an implement fluid cooling core. The implement cooling core and the receptacle are connected by at least one, but preferably two connector bars. The connector bars are resiliently connected to an associated supportive frame.
