Sorry Brad....I was trying to go off the book which is very difficult to read and understand........
I found this on the
Vortex site..............
1. The power take off (PTO) unit found on a
Vortex is also commonly used in a variety of commercial and industrial applications such as farm tractors, street sweepers and dump trucks. The PTO on a
Vortex is a clutch / gear combination PTO that transfers the energy (power) of the trucks engine to the cleaning machine by means of the truck's automatic transmission. The PTO unit is designed to bolt directly up to the truck's transmission "PTO port". The
Vortex PTO is a "hot shift" or "constant mesh" type PTO and differs from "manual" PTO's which require the manual engagement of the PTO gear teeth into the transmission PTO gear by the operator from a lever in the truck's cab.
2. The gear in the
Vortex PTO and the automatic transmissions PTO gear are constantly meshed and are always turning while the engine is running. However, the PTO drive shaft will not begin to turn unless the clutch pack inside the PTO is engaged. The PTO clutchpack is engaged when the "PTO START" button is depressed on the
Vortex instrument/control panel.
3. When the "ENGAGE PTO" button on the
Vortex instrument / control panel is depressed, The PTO solenoid (12V solenoid located near the PTO or transmission) becomes energized (the solenoid orifice opens). This allows pressurized transmission fluid from the truck's automatic transmission to flow through the solenoid and into the PTO clutchpack. This engages the clutch pack and turns the PTO output driveshaft. The engagement of the clutch pack inside the PTO occurs when pressurized transmission fluid flows into it.
4. When the PTO clutch pack is engaged the PTO drivehaft will turn, powering the machine's vacuum pump, high pressure water pump and Xentherm pump through a series of belts and pulleys.
