Auxiliary equipment require power take-offs, either when the truck is stationary or when it is in motion. Various power take-off alternatives can be chosen, depending on the bodywork. The work is generally carried out by equipment which ispowered by a hydraulic motor. The hydraulic motor, together with a pump and associated equipment, form the basis of the hydraulic system. The pump, which provides the hydraulic pressure and flow to the motor, is the heart of the hydraulic system. All power take-offs covered by this chapter are available factory installed. Some variants can also be ordered from
Volvo Parts AB
For further information about:
• Power take-offs and Hydraulic pumps, please refer
to “Product and variant information” and the
booklet “Power Take-Offs and Hydraulic Pumps”.
• Essential dimensions with the power take-off fitted to
the vehicle, please refer to “Supplementary
• Wiring diagram for connecting a power take-off to
Powertronic gearboxes, please refer to Body builder
instruction “Vehicle electronics”.
• Power take-off working conditions and parameter
settings, please refer to Body builder instruction “Vehicle
It is important to dimension an optimum hydraulic system, and to specify the correct pump size to provide sufficient oil flow and prevent overloading of the power take-off. For recommended instructions, please refer to: “Dimensioning of hydraulic system and hydraulic pumps”, page 3.
NOTE: The body builder should enclose an information binder, delivered with the truck, including hydraulic system data( system dimensioning description and dimensioning criteria).
There is a number of different power take-off variants available, with single or double outlets. The power takeoff is supplied with either a flange connection and/or a direct connection to the hydraulic pump (opening with a splined DIN connection). Power take-offs are classified into two family variants:
Clutch dependent and Clutch independent
PTR = Single power take-off gearbox, rear mounted (Power take-off Transmission Rear). All are rearfacing.
PTRD = Double power take-off gearbox, rear mounted (Power take-off, Transmission, Rear mounted,
PTPT = PowerTronic power take-off (PowerTronic Power Take-off). Torque converter mounted. Available with rear-facing flange or opening for hydraulic pump, both located at 11 o’clock as seen from rear of gearbox — Not available for FH.
PTER = Engine mounted power take-off located at the rear end of the engine (Power Take-off Engine Rear.)
EPTT = Maximum permitted torque on engine power take off (Engine Power Take off Torque)
TPTT730 = Gearbox power take-off torque capacity 730 Nm
Clutch dependent power take-off
When the truck is parked. Common applications are tipping trucks, mobile cranes, tank trucks etc.
They are mounted on the gearbox and stop working when the clutch pedal is depressed.
Note: The clutch pedal must be depressed to engage or disengage the power take-off.
Clutch independent power take-off
A clutch independent power take-off is mainly used when work is to be done when driving. Refrigerators, hook lifts, concrete mixer, snow ploughs/sand spreaders,
These power take-offs are mounted on the front upper part of the gearbox and are driven by the engine via the gearboxes’ torque converter housing..
• PTPT-D Automatic gearbox driven PTO, 1 front/upper DIN connection for plug-in pump
• PTPT-F Automatic gearbox driven PTO, 1 front/upper rear facing SAE flange connection for prop shaft
An engine mounted power take-off is mounted on the rear of the timing cover.
D11, D13, D16
On the D11, D13 and D16 engines the power take-off is ordered separately, either as:
• PTER-DIN (DIN5462/ISO7653 connection)
• PTER–100 (flange DIN 7646) (not D13)
• PTER1400 (flange SAE1400)
The hydraulic pump (variants HPEXXX) is ordered separately on these engines together with PTO variant PTERDIN:
• PTER-DIN + HPEXXX
(Engine power take off together with engine mounted hydraulic
