The Toyota Landcruiser presents a easily converted vehicle due to the size of the vehicle, the engine capacity and the space available for needed components. For either a drive shaft driven of hydraulic powered air compressor to be installed, a suitable power range from the vehicle is required. The Toyota Landcrusier is one of the easier vehicles to have the equipment installed into. The system utilises what is known as the PTO, Power Take Off. The Toyota Landcrusier has an FPTO, Full Power take Off.

Toyota Landcrusier has the engine power and tray size to make this style of vehicle perfect for a shaft drive air compressor and an air powered vacuum system installed on the tray.

The FPTO utilizes a dog clutch mounted to the rear of the transfer case
driven via the main input shaft from the transmission. Full engine
TORQUE (430Nm) is available at the FPTO output shaft and the output
speed (RPM) is relative to the gear selected. This means that with the
transfer case in neutral, the main gearbox in 4th gear the speed ratio is
1:1.
Other gear ratios may be selected, for optimum engine RPM.

Operation of the FPTO is as described below,

  •  Engage hand brake
  •  Put main gear box in neutral
  •  Put transfer case in neutral
  •  Depress clutch pedal
  •  Engage the PTO
  •  Select 4 gear on main gear box
  •  Release clutch pedal slowly

  •  Disengage the PTO
  •  Release clutch pedal
  •  Re-engage transfer case
  •  Release hand brake

The FPTO is actuated by a cable in the cab, two micro switches are
installed on the cable control, one is interlocked with the hand brake
and a beeper to allow the FPTO to be engaged if the hand brake is
released while the FPTO is engaged the beeper will sound, the other is
interlocked with 1. the reversing sensor to shut down the engine if the
operator accidentally shifts into reverse, 2. to indicated the FPTO is
engaged and allow the throttle control or governor to control engine
speed. Engine speed governor is via our electronic pedal interface or
our electronic compressor throttle control
