The OMSI PFT-PCV/3000 W/C (With Clutch) is a high-capacity split-shaft transfer case / power take-off unit built for severe vocational applications. Ideal for dry vacuum trucks, sewer combination machines, industrial blowers/pumps, and other auxiliary equipment, it allows for auxiliary (PTO) outputs to be engaged while the main drive shaft remains in rotation—eliminating downtime and improving operator efficiency. It’s engineered for heavy torque, seamless switching, and reliability under harsh operating and environmental conditions.
Key Features
- Clutch-Controlled Engagement: Allows output(s) to be engaged/disengaged without stopping the main shaft. This feature reduces wear, saves time, and reduces operator effort.
- Split-shaft design: Supports multiple output flanges (pump, blower, etc.) while keeping input connected for main drive when required.
- Vertical mounting option: Designed to fit above frame rails, allowing auxiliary equipment to be mounted high, improving clearance and simplifying upfit.
- Pneumatic control: A double-acting shifter cylinder (requiring typical air pressure) manages diversion between main drive and auxiliary/road mode safely. Includes a bypass in case of loss of air pressure.
- Safety & warning systems: Includes pressure switch, optional alarms or indicator for lubrication pump, and oil level sight glass or remote reservoir for easier monitoring.
Technical Specifications
- Main Drive Continuous Torque: ~15,500 lb-ft torque (≈21,000 Nm) continuous load
