Simple Modification Boosts Air Conditioning On Cat Challenger TRACTORS Modifications 25-1-28 Orlin Schanz boosted performance of the air conditioner in his 1975 Cat Challenger by making a simple modification using a piece of pvc pipe.
"It improves performance 100 percent," says Schanz, who came up with the idea after several years of sweltering heat inside the cab of his Challenger.
The idea is to recirculate air from inside the cab to the air conditioner, rather than continuously bringing in outside air. "It lets you cool down air that is 70? rather than air from under the hood that's 195?. And the way I did it, the recirculated air is filtered."
He used a piece of 2-in. dia. plastic pipe fitted with threaded end couplers and nuts. He fitted the pipe into holes cut into the bottom of the air conditioner unit, just below the filter, and in the firewall of the cab. Then he simply taped over the air intake louvers on the side of the air conditioner so air must be drawn in through the pipe.
