Power take-offPTRD-D2Fact Sheet
The PTRD-D2 is a gearbox-mounted, clutch dependent power take-off with twin rear flange connections for directly mounted propeller shafts, and a front DIN con-nection for a directly mounted hydraulic pump.
The power take-off is available for manual gearboxes, I-Shift included. It is driven via the gearboxes’ intermediate shaft and is mounted on the rear side of the gearbox. Rpm and output are governed by the engine’s speed and the gearboxes’ gear ratio. Clutch dependent power take-offs can only be used when the vehicle is at a standstill, and they are engaged by a pneumatic system. The power take-off stops when the clutch pedal is depres-sed, which means that this power take-off can only be used when the vehicle is at a standstill.The power take-off is suitable for applications such as:• Timber crane• Bulk transport
The following product features characterise the PTRD-D2:• Fitted on the rear side of the gearbox and driven via the
gearboxes’ intermediated shaft.• Robust dimensions offer high operating reliability and a
long service life.• Rpm and output are governed by the engine’s speed and
the gearboxes’ gear ratio.• Reliable engagement is carried out by a pneumatic sys-
tem.• Double housings with twin rear flange connections for
directly mounted propeller shafts, and a front DIN con-nection for a directly mounted hydraulic pump.
• Available for manual gearboxes, I-Shift included.

PTRD-D2
Clutch dependent power take-off
The power take-off (1) is mounted on the rear side of the gearbox.A connecting shaft (2) transfers power from the gearboxes’ intermediate shaft to the power take-off’s input shaft (3), from which power is transferred via the power take-off’s intermediate shaft (4) to the output shaft (5). The intermediate shaft (4) also serves as an output shaft.
Engagement/disengagement from the
driver’s seat
Engagement and disengagement are done with two conveniently located switches on the instrument panel.The left switch, marked 1, activates the outer flange connection (SAE 1310). The right switch, marked 2, activates the inner flange connection (SAE 1410). The hydraulic pump flow starts regardless of which of the two switches is activated.The pneumatic and mechanical design is constructed as follows: An engaging ring (6) connects the con-necting shaft (2) to power take-off’s input shaft (3). The engaging ring is operated with a selector fork (7) by a compressed-air powered piston (8) in the control cylinder (9).The compressed air for the respective control cylinders is regulated by a so-lenoid valve.
