Without power take-offs (PTO), trucks lack the versatility required to transport materials. That’s because a PTO directs power generated by the engine to the auxiliary components that are doing the actual work. Still curious about what a PTO on a truck is? Continue reading to learn more about power take-offs and how to select the one that’s right for your truck.
A power take-off (PTO) is a mechanical gearbox used to transfer power from the engine and transmission of a truck to supplementary elements, such as hydraulic pumps. The pump generates a hydraulic flow that’s transferred to cylinders and hydraulic motors as their power source.
Typically, the transmission on large hauling vehicles, like dump trucks or tankers, has openings on each side to connect the PTO on a tanker. PTO applications like pneumatic blowers, vacuum pumps, and liquid transfer pumps use a rotating drive shaft to supply power directly to the components. Power take-offs can be engaged via cable, air pressure, or hydraulic pressure.
One of the most vital aspects of choosing your power take-off is matching it to the equipment used in your PTO truck. Other considerations include:
- Input horsepower
- Operating speed of driven equipment
There’s a wide variety of transmissions available on the market, which leads to multiple mounting types for PTO trucks. It’s essential to choose the correct mounting for your specific PTO truck. One of the first things to consider is the aperture of your transmission.
Transmissions have openings on both sides, each of which allows the installation of a PTO. Depending on the manufacturer, apertures may be standard or nonstandard sizes. Power take-offs also require a specific number of bolts to fasten to the transmission; 6-bolt and 8-bolt designs are common, while some manufacturers offer 10-bolt designs as well.
Mounting options include rear, reversible, split shaft, and Ford super duty. Split shaft PTOs attach behind the transmission, within the truck’s drivetrain. Because of that, they need to be specially mounted to the chassis frame.
