OMSI PFT-300 Transfer Case

The PFT-300 from OMSI is a mid-range, split-shaft transfer case unit designed for lighter vehicles (typically 50-100 kW) that require reliable auxiliary drive capacity. Common in municipal, service, firefighting, sewer cleaning, and similar applications, it enables secondary equipment (pumps, blowers, hoppers, etc.) to be driven either via the vehicle’s drive shaft or via displacement outputs. The PFT-300 is engineered to offer flexibility in mounting, output orientation, and control methods.

Key Features

• Split-shaft design: Enables engagement of auxiliary outputs without fully disengaging the main drive in certain configurations.
• Dual control options: Available with manual control (mechanical linkage) or pneumatic actuation for engagement. Some versions can operate output shafts while moving, depending on configuration.
• Multiple mounting orientations: Standard horizontal, inverted (upside down), and vertical mounting options allow installation flexibility under the chassis, on sides, or overhead.
• Auxiliary output compatibility: Able to drive hydraulic pumps, driveshafts, or service equipment. Outputs for both side shafts and central outputs depending on model.
