If a PTO is present, it will be mounted on either the left side or the right side for
a 3000 MH transmission depending upon the converter housing con
PTO is located on the left side or top for a 4000 MH Series transmission. The
PTO drive gear is engine-driven and therefore provides direct engine power. The
PTO can be operated when the vehicle is either moving or stopped.
The PTO gear is in constant mesh with the drive gear in the converter housing.
PTOs are either constant drive (output always powered) or clutched drive. The
output of a clutched drive PTO is powered when the PTO clutch is pressurized.
Be sure that the limits for PTO engagement speed and operational speed are not
exceeded. Consult the vehicle manufacturer’s literature for these speed limits.
Also, all Motorhome Series-equipped vehicles with PTO enable have engagement
and operational speed limits programmed into the ECU to help protect PTO
equipment. Some speed limits have default values which are programmed out of
the operating range and will need to be set for your particular PTO duty cycle.
Consult your vehicle manufacturer to see if your transmission has been
programmed and what operational limits have been established.
When the programmed engagement speed is exceeded, the PTO will not engage.
The PTO engagement must be retried after the speed has been reduced. When
operational speeds (either engine or transmission output) are exceeded, the PTO
will deactivate and the PTO engagement process must be repeated.
