How does a PTO work on an automatic transmission?

How does a PTO work on an automatic transmission?

The PTO is the link between the truck’s transmission and the hydraulic pump, blower, or motor doing the work to complete the job. The PTO converts power from the engine and transmission to an output we can manipulate to drive hydraulic components in various ways to produce a service that generates revenue.

Does the PTO run off the transmission?

The PTO is engaged and disengaged using the main transmission clutch and a remote control mechanism which operates on the PTO itself. Typically, an air valve is used to engage the PTO, but a mechanical linkage, electric or hydraulic mechanism are also options.

How does a clutch shift PTO work?

For power shift operation, when a power shift PTO is engaged, a solenoid is energized. Air or hydraulic fluid then compresses a clutch pack in the PTO. This locks the PTO output gear to the output shaft and allows work to be done. When the power shift PTO is disengaged, the solenoid de-energizes.

How does PTO work Power Take Off?

PTO (Power Take Off) generates power by changing engine rotation to “Hydraulic”. Hydraulic pressure is a mechanism that uses fluid called hydraulic fluid as an energy transmission medium. Also, when PTO changes engine energy to hydraulic pressure, a part called “PTO shaft” is required.

How is PTO power calculated?

  1. POWER TAKE-OFF SPEED. PTO Speed = Engine RPM x PTO %
  2. Mechanical Horsepower. Horsepower = Torque x RPM / 5252.
  3. RPM. RPM = Horsepower x 5252 / Torque.
  4. Capacity of a Reservoir. Gallons = Length x Width x Depth / 231.
  5. Motor Output Horsepower.
  6. Pump Input Speed.
  7. Pump Input Torque.
  8. Heat Equivalent of Fluid Power.

How does the Meritor 12 speed auto work?

The transmission clutches itself with an air operated slave cylinder. It’s a two pedal fully automatic operation. I sometimes had to stop and restart the truck to get the Meritor to reset itself after it would lose its mind every so often when using it manually. Oxbow Thanks this.

Where is the PTO on a Meritor freedomline?

The ZF/Meritor Freedomline transmission offers a rear mount PTO output location. You will find this at the right rear of the main transmission housing. There is only this one opening available on this series of transmissions. The transmission elec- tronics must also be programmed for PTO operation.

Is the ELEC tronic transmission compatible with PTO?

The transmission elec- tronics must also be programmed for PTO operation. If you are unsure whether or not your transmission is equipped for PTO operation, then contact your Vehicle dealer and they will contact ZF/Meritor for verification. The Freedomline transmission is available in different forward speeds. Identification is found on the ID tag.

Can you install a PTO with the engine running?

DO NOT ATTEMPT TO INSTALL OR SERVICE ANY POWER TAKE- OFF WITH THE TRUCK ENGINE RUNNING. PUT THE IGNITION KEYS IN YOUR POCKET BEFORE GETTING UNDER THE TRUCK. DO NOT ALLOW TRUCK ENGINE TO BE STARTED WHILE WORKERS ARE UNDER THE TRUCK.
