Oshkosh Fas Gearbox Assembly

Oshkosh Fas Gearbox Assembly

This component is a steering miter gearbox, also known as a miter box, designed for heavy-duty Oshkosh front discharge mixer trucks. It functions as a right-angle drive, typically with a 1:1 gear ratio, to transmit steering inputs through intersecting shafts. This gearbox is a critical part of the steering linkage, especially in vehicles with complex steering geometries, ensuring synchronized wheel movement. It would be replaced due to wear, damage, or failure, which would manifest as loose or unresponsive steering.

Key Features

• Durable cast housing for protection against on-site conditions
• Typically features a 1:1 gear ratio for direct rotational transfer
• Keyed shafts for secure connection to steering linkage
