Description of Change: The Upshift/Downshift Switches on Track-Type Tractors have been improved. The reliability of these switches has been improved by adding a protective covering over the switch wires. The wire insulation on the switch wires has also been changed to TFE Fluorocarbon. These changes will eliminate wire chafing which can cause switch failure. Adaptable To: The improved 132-7419 Push Button Switch (Downshift) and the improved 132-7450 Push Button Switch (Upshift) are adaptable to the machines that are listed above.
