Mounting the PTO (Continued)
Final Installation Steps
1. Remove the filler plug from the transmission and
add recommended transmission lubricant to the level
prescribed by the transmission or truck manufacturer
( Fig. 16 ).
NOTE: If the PTO is mounted below oil level, additional
lubricant will be required.
2. Run the PTO for 5-10 minutes and check for oil leaks and
noise.
3. Should a quiet PTO become noisy after the universal joint
connection is made, check the PTO driveline components
for an out of phase condition, excessive or unequal joint
angles or possibly worn parts in the driven accessory.
4. Re-torque all mounting bolts, nuts, cap screws and set up
inspection routine of the PTO driveline components and
the driven auxiliary equipment.
NOTE: Anticipate slight increase in PTO noise level as oil
thins out at operating temperatures.
PTO Installation Tips for Automatic Transmissions
The procedure for installing a PTO on an automatic is basically the same as for a mechanical
transmission. Power Take-Offs for automatic transmissions are assembled with a special drilled input
shaft which allows the input gear to be pressure lubricated during operation. (See page 35 ).
After installing a PTO on an automatic transmission, connect pressure lubrication hose to the PTO and
the transmission per installation instructions shown on pages 35-38 of this booklet.
WARNING:
Adapter assemblies are never used on an automatic transmission, unless specified on
the application page, because they do not have pressure lubricated design features.
WARNING:
Use only wire control with PTO made for wire cable control. If lever is desired, order
PTO for lever control. The internal shifting mechanism for wire is not designed for heavy forces usually
encountered with lever control linkage.
