Muffler, Air Cleaner Rerouted On allis-Chalmers Tractor TRACTORS Made-It-Myself 18-2-9 Most new tractors equipped with cabs have the air cleaner under the hood and exhaust muffler mounted on the side to improve visibility. Lloyd Robertson, Worthington, Minn., "modernized" his 1980 Allis-Chalmers 6080 tractor by rerouting the exhaust pipe to the right side of the tractor and tucked the air cleaner under the hood.
"It was a fairly simple job and cost less than $80 for exhaust pipes and fittings," says Robertson. "I now have a much better view from the cab. It's especially helpful when planting corn because I can see the furrow mark much better."
The tractor's batteries originally were mounted in front of the radiator. Robertson moved them onto a rack beside the engine, then lowered the air cleaner down into the area vacated by the batteries.
To reroute the exhaust, he discarded the muffler and then bought two lengths of 2 1/2-in. dia. exhaust pipe and a pair of 90 degree elbows from a local truck supply store. He used the elbows to run exhaust from the turbocharger back alongside the engine and up the corner of the cab, welding the pipes to the flanged connections on the elbow. He used sheet metal to cover the holes in the hood where the exhaust muffler and air cleaner had been. `"The exhaust pipe is hidden behind the corner cab post and out of the driver's view," says Robertson. "I mounted a bracket on top of the cab to support the pipe, using a piece of tire tread to make a vibration dampener between the pipe and cab. Because there's no muffler, the engine sounds different from outside the tractor. However, the engine is turbocharged so there's no more noise inside the cab now than there was with the muffler.
"Moving the batteries to the side makes them more accessible for service and also keeps them cleaner. I still have plenty of room to service the precleaner."
