CAUTION
TO PREVENT POSSIBLE INJURY:
- DO NOT go underneath the vehicle with the engine running.
- DO NOT attempt to work on an installed Power Take-Off with the engine running.
- DO NOT operate the controls of the Power Take-Off or other driven equipment from underneath the vehicle with the engine running.
- DO NOT operate the controls of the Power Take-Off or other driven equipment in any position that could result in getting caught in the moving machinery.
Make sure to block any moving or raised device that may injure a person working on or under the truck. A lever or its linkage may be accidentally moved causing movement of the device which could cause injury to a person near the device.
IMPORTANT
Because most of our Bezares Power Take–Offs and P.T.O. drive lines are sold through distributors, the product applications and the resulting degree of exposure to danger of the operators are beyond the knowledge and controls of BEZARES.
Therefore, the proper installation of the P.T.O. and its associated equipment, and the decisions of whether to install guards and/or warning signs shall be the responsibility of the designers or installers.
Since it is our major objective to show you how to get additional and more profitable miles from truck, tractor and trailer components, we want to provide you with information on the installation of 3200, and 3800 Series.
We all realize that an inadequate transmission will overwork any Power Take–Off in a very short period of time. In addition, a mismatched transmission/P.T.O. combination can result in unsatisfactory performance of the equipment right from the start.
Before you order new trucks be sure that you’re getting the right transmission/P.T.O. combination. It is of vital importance for efficient performance to have adequate power.
To help you select the proper type, size and design of P.T.O. it is advisable to discuss your specific requirements with a Bezares P.T.O. specialist. They know their products and Power Take–Offs. They can inform you about everything you need to know about power, at the right time, before you specify components.
Here are some of the questions that are relevant to the Proper Selections of a Transmission mounted Power Take–Offs.
- What is the make and model of your transmission?
- Which P.T.O. opening will be used?
- What accessory is to be driven?
- How much horsepower is required to drive the accessory?
- What is the required rotation of the P.T.O.?
- What is the required P.T.O. output shaft speed as a percent of engine speed?
Once all of the answer to these questions have been determined, a transmission mounted P.T.O. can be selected to meet the horsepower, speed and rotation that you require.
Check out our PTO Selection form at bezares.com/pto-selection-tool/
Having made the selection of a P.T.O., you are ready to start the installation.
- Drain the oil from the transmission and the PTO aperture cover plate.
- Discard the cover plate and cover plate gasket, then clean the aperture pad using a putty knife or wire brush.
Note: Stuff a rag in the aperture opening to prevent dirt from entering the transmission while you are cleaning it. - Install the proper studs and pins (furnished with the PTO) in the pto aperture pad. (See also specific mounting instruction furnished with the PTO).
- Place the correct number of gaskets over studs. Do not use paste between because you may want to add or subtract gasket to obtain proper backlash.
Do not use more than 3 gaskets together, USUALLY ONE GASKET 0.020” (0.5mm) will be required. - Fasten the PTO to the transmission by means of the bolts and remaining nuts.

CAUTION
CAUTION: This vehicle is equipped with a Power Take-Off. Shut engine off before working on the Power Take-Off or getting below the vehicle.
Consult the operating instructions before using the P.T.O. (see sun visor)
POWER TAKE-OFF OPERATION – VEHICLE STATIONARY
Automatic Transmission with Power Shift P.T.O.’s
Engage the P.T.O. with the engine at idle speed.
NOTE: Power Shift P.T.O.´s: The engine must be at idle or below 1000 RPM when the P.T.O. is engaged. See the transmission manufacturer’s instructions for special procedures.
IMPORTANT:
Failure to follow the proper shifting or operating sequences will result in premature P.T.O. failure with possible damage to other equipment.
Warning: Cold Weather Operation of Power Shift P.T.O.´s
During extreme cold weather operation [32°F (0°C) and lower], a disengaged Power Shift Power Take-Off can momentarily transmit high torque that will cause unexpected output shaft rotation. This is caused by the high viscosity of the transmission oil when it is extremely cold. As slippage occurs between the Power Take-Off clutch plates, the oil will rapidly heat up and the viscous drag quickly decreases.
The Power Take-Off output shaft rotation could cause unexpected movement of the driven equipment, resulting in serious personal injury, death, or equipment damage.
To avoid personal injury or equipment damage:
- Driven equipment must have separate controls.
- Driven equipment must be left in the disengaged position when not in operation.
- Driven equipment must not be operated until the vehicle is allowed to warm up.
IMPORTANT
Failures to follow proper shifting or operating sequences will result in premature P.T.O. failure with possible damage to other equipment.
