DETAILED DESCRIPTION OF THE DISCLOSED EMBODIMENTS

[0013] For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the embodiment illustrated in the drawings, and specific language will be used to describe that embodiment. It will nevertheless be understood that no limitation of the scope of the invention is intended. Alterations and modifications in the illustrated embodiments, and further applications of the principles of the invention as illustrated therein, as would normally occur to one skilled in the art to which the invention relates are contemplated hereby and desired to be protected. Such alternative embodiments require certain adaptations to the embodiments discussed herein that would be obvious to those skilled in the art.

[0014] An embodiment of a mounting system may include an A/C compressor bracket specifically designed to mount at least an R4 or R4-style A/C compressor, manufactured, by way of example and not limitation, under the following names: General Motors, Frigidaire, Delco, Harrison, Global, and Delphi. The automotive industry generally refers to this style and model compressor as an R4 compressor, regardless of the specific manufacturer thereof. Examples of the R4 compressor may include a 7-inch diameter or a 7-inch diameter housing. These compressors are original equipment on many models of General Motors vehicles at least from 1979 thru 1995 that use a single, serpentine belt-drive system. The R4 compressor is available with either a 4-inch pulley clutch or a 5-inch pulley clutch. The R4 compressor has approximately 10 cubic inches of displacement per revolution with four cylinders radiating from its crankshaft, making it ideal for installing with the GM LS engine model. The mounting system nay use a spring-lever tensioning assembly, for example, from a 1999 to 2006 Jeep with a 4.0 L engine. This may allow mounting the compressor 7 inches from the engine center-line of the small block V8, which may eliminate the need for an upper idler assembly and decreasing the serpentine drive belt length.

[0015] The mounting system is structured to mount the compressor to the top portion of the engine so that the mounted compressor fits within the engine compartment of the 1979-1995 model vehicle and so that the mounted compressor is proximate to its OEM location said vehicle. The mounting system may be used to install a GM LS or LSX based engine into various makes and models of cars and trucks that predate model year 2000 and, in particular, that comprise model years 1979 thru 1995. The mounting system may include a combination of plates, spacers, bolts, a rear support brace, and a tensioning assembly with a slotted rear cam plate to aid in adjustments for various drive belt lengths of various accessory pulley sizes and combinations.

[0016] The mounting system may fit various LS engines, including LS engines with, for example, different offsets/drive spacing. The offset/drive spacing references the distance used on the front drive of the LS engine. The crank pulley offsets/drive spacing may include: Corvtte crank pulley 2; Camaro crank pulley 2 15/16; Truck/SUV crank pulley 3 11/16; and 2010-2013 Camaro crank pulley 3 11/16. The mounting system of the present invention connects to the same location on the various LS engines. Adjusting the bolts and spacers of the mounting system provides the flexibility to use the mounting system on various LS engines and with various R4 compressors. The bolts may comprise a plurality of lengths including 25 mm, 45 mm, 70 mm, 110 mm, and 130 mm. The spacers may comprise a plurality of lengths including 0.725 in, 0.863 in, and 1.577 in.
