54 POWER TAKE-OFF (PTO)
When installed, PTOs are typically attached to the truck’s transmission and rotate at some percentage of the engine RPM. Components driven by the PTO can be connected by a driveshaft or coupled directly to the PTO. Some examples of equipment could be a product pump, blower, vacuum pump, or hydraulic pump to name a few. Each of these components must be sized appropriately for the designed load and speed among other demands.
For proper operation always refer to the manufacture’s operating and maintenance instructions.
(Warning example from Muncie power products)
The switch or control to engage and disengage the PTO may be located inside the vehicle, out side the vehicle such as in a cabinet or located in both positions.
Always know how and where to disengage a PTO.
Never exceed the designed maximum engine RPM for a system. Know the maximum engine RPM for safe operation.
PTO’s and their driven components rotate and can generate pressure. Pressure relief devices or bypasses are typically employed to manage these pressures.
Always follow recommended procedures for selecting, installing, operating, or repairing a PTO as found in the PTO’s manuals, service parts lists, and application guides.
