All power take-offs are particularly designed for generating hydraulic pumps to SAE J744C series ‘B’ specification with splined input shaft and either two-bolt or four-bolt fixing. The utmost power which can be transmitted is certainly 22 KW (29.5 bhp) per 1000 rev/min engine speed; this equates to a torque of 209 Nm (155 Ibf.ft. – 21.33 kgm.).For PRM1000 the clutched power take-off provides pump rotation the same as the engine, where as the direct drive power take-off for the PRM500 and PRM750 will give opposite rotation. Power to the pump isn’t affected by the normal usage of the gearbox for propulsion responsibilities. All ancillary power circuits powered by PRM power take-offs ought to be designed relative to the suggestions of the hydraulic gear manufacturer, and really should be correctly safeguarded against overloading.
PRM power take-off products fit on the trunk face of the main gearcase and are driven by the insight shaft; consequently they may be operated all the time whilst the engine can be running, The power take-off replaces the end cover which is generally installed and performs the functions of the finish cover by sealing the gearbox against loss of oil and properly positions the input shaft rear bearing. Power take-off devices provide the link between the gearbox and the hydraulic pump.
Direct Drive Power Take-Off
Available on the PRM500 and PRM 750 the direct drive power take-off is driven directly from the gearbox insight shaft; consequently it will operate at all times when the engine is usually operating, and since there is absolutely no clutch for disengagement of the hydraulic pump, provision should be made in the auxiliary hydraulics circuits for pressure by-move to the reservoir when capacity to the pump is not needed. A set of 1:1 ratio gears, providing sufficient offset between the gearbox result shaft and the centreline of the energy take-off to make sure there is sufficient clearance between the hydraulic pump and propeller shaft coupling.

You’ll find that there are lots of sources offered for info relevant to pto gearbox, but obviously they are of varying levels of reliability.
