Cummins ac brackets
The ac bracket generally referred to as the high mount was used on Ford and Freightliner medium dutys. The cummins part number for the mount is 3930822. The upper alternator mount is 3920862 and the lower one is 3930820. The lower water inlet on the Fords usually turns straight down. This generally won't work on a GM. There is one that goes straight out that will clear on those. The upper water outlet points straight up. The hose goes up and over the alternator arm. The ac compressor for this bracket can be found on ebay listing for Ford/Sterling ac compressor. The alternator bracket is designed for a 21si or 22si J180 style unit. These were used on virtually every medium duty truck. These alternators are 1 wire and have an output terminal for your charge light and one for a tach. You can use a Dakota Digital interace to link to your factory tach. There is also a cummins bracket that mounts an ac compressor on the top drivers side beside#1 valve cover. This one is found on Case tractors and uses an accessory V belt pulley mounted on the fan hub. I priced this set up once and it was between $400 and $500 just for the bracket, pulley and belt. You could probably have one custom made cheaper.The guys at GOS Performance have custom ac brackets. The high mount bracket can be found on virtually every Ford/Cummins medium duty application including school buses. Many times you will see the bracket without an ac compressor but has an ac delete pulley in its place. That way the belt length is the same with or without ac. Hope this info helps. I plan to use a high mount bracket but am putting my Ford vacuum pump in the ac spot. That will put it in exactly the same area as original.
