Safety Information
CAUTION:
TO PREVENT POSSIBLE INJURY OR DEATH: 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.
CAUTION:
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 BZ U.S.A.
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.

Foreword
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 3131, 3151 and 3252 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.
P.T.O. 3131 SERIES
(Heavy Duty)
P.T.O. 3151 SERIES
(Heavy Duty - Constant Mesh)
P.T.O. 3252 SERIES
(Heavy Duty - Low Profile)
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.

Aplication Questions
Here are some of the questions that are relevant to the Proper Selections of a Transmission
mounted Power Take–Offs.
1. What is the make and model of your transmission?
2. Which P.T.O. opening will be used?
3. What accessory is to be driven?
4. How much horsepower is required to drive the accessory?
5. What is the required rotation of the P.T.O.?
6. 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.
Having made the selection of a P.T.O., you are ready to start the installation.

P.T.O. 3151 For World Transmission

Mounting P.T.O. To Transmission
Remove the pto’s opening cover
Clean the opening surface of paste
or gaskets residues. Be careful to
avoid damages or scratches in the
opening’s surface
Place the steel gasket using grease,
if necessary, to keep it in position
The ribbed surface should face
towards the installer
Unscrew the backlash check plug
The transmission’s drive gear
and opening will be visible
Fit the guides with a screwdriver.
Use loctite to avoid unscrewing them
Fit at least with 4 bolts in each corner
before checking the backlash

Mounting P.T.O. To Transmission
Check the suitable backlash. It should
be between 0.006” and 0.015”
Install the cartridge and tightening
to 25 - 30 Lb.ft (35 - 40 Nm).
Alternativelly, for easy installation,
it can be installed on the pto before
it being placed on the transmission
Install the pressure switch.
Alternativelly, for easy installation,
it can be installed on the pto before
it being placed on the transmission
Install the other end of the the
pressure line in the pto.
Tight to 12 - 14 Lb. Ft. (18 - 20 Nm)
Screw the remaining bolts at 44 -
50 lb.ft (60-68Nm)
Place the coil. Ensure the O-rings
are in place to avoid water leaks
inside the coil
Install the fitting to transmission
according to the suitable port
specified in page 12, tight to
8 - 10 Lb. Ft. (11 - 14 Nm)

P.T.O. Shifting Procedure & Precautions
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
extrememly 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 nor in operation.
- Driven equipment must nor be operated until the vehicle is allowed to warm up.
