Particular applications will require the use of a split-shaft transfer case to decouple
the drive axles and fully divert engine power to auxiliary equipment. The
Split Shaft
PTO Installed
parameter must be enabled in the CECU using the Electronic Service
Analyst (ESA) tool. Enabling this parameter will allow the transmission to be in gear
while the parking brake is engaged without displaying the associated warnings and
audible alarms. PACCAR recommends consulting the transmission and/or transfer
case manufacturer for details on proper configuration for split-shaft PTO devices.
Note: PTO functionality for remote station controls and hardwired PTO
engagement feedback is not currently available for vehicles equipped with
Allison and Ultrashift transmissions in applications which require the
transmission to be in-gear during PTO operation. Vehicles with these
configurations and requirements must rely on in-cab control configurations to
allow PTO mode functionality, or provide J1939 PTO message to request the
engine to enter PTO mode.
