1)	If the specified temperatures cannot be maintained due to extreme operating parameters, please contact us.
2)	The FKM shaft seal may be used for case drain temperatures from -25 °C to +115 °C. For the temperature range below -25 °C, please contact us.
3)	Equates e.g. with the VG 46 a temperature range of +5 °C to +85 °C (see selection diagram)

Explanatory note regarding the selection of hydraulic fluid

The hydraulic fluid should be selected such that the operating viscosity in the operating temperature range is within the optimum range (vopt see selection diagram).

Selection diagram

Filtration of the hydraulic fluid

Finer filtration improves the cleanliness level of the hydraulic fluid, which increases the service life of the axial piston unit.

A cleanliness level of at least 20/18/15 is to be maintained according to ISO 4406.

At a hydraulic fluid viscosity of less than 10 mm²/s (e.g. due to high temperatures in short-term operation) at the drain port, a cleanliness level of at least 19/17/14 according to ISO 4406 is required.

For example, the viscosity is 10 mm²/s at:

HLP 32 a temperature of 73°C HLP 46 a temperature of 85°C

Notes

The values given are maximum values and do not apply to continuous operation. The axial force in direction Faxmust be avoided as this would reduce the bearing life service. Radial forces are not permissible.

Direction of rotation

The direction of rotation of the axial piston unit is defined by means of a pressure nipple screwed into the service line port and can easily be changed.

By changing the pressure nipple, the service line port and the suction port are exchanged. This is e.g. required when mounting at a PTO with an counter-clockwise direction of rotation.

The process of converting the pressure nipple can be seen from the instruction manual (91520-01-B, chapter 6.4.2 “Direction of rotation and changing the direction of rotation”).

Direction of rotation on delivery

On delivery, the pressure nipple (1) is pre-assembled in the right service line port of the axial piston unit. The permissible drive direction of the pump looking at the drive shaft: counter-clockwise. The power take-off turns clockwise.

Note

The pressure nipple is pre-assembled on delivery and must be tightened to the torque specified for the thread size before installation (see instruction manual).

Installation instructions

General

During commissioning and operation, the axial piston unit must be filled with hydraulic fluid and air bled. This must also be observed following a relatively long standstill as the axial piston unit may drain back to the reservoir via the hydraulic lines. The pump housing is internally connected to the suction chamber. A separate drain line from the housing to the reservoir is not needed. To achieve favorable noise values, all connecting lines should be decoupled by using elastic elements and above-reservoir installation is to be avoided. In all operating conditions, the suction and drain lines must lead into the reservoir below the minimum fluid level. The permissible suction height hS results from the overall loss of pressure; it must not, however, be higher than hS max = 800 mm. The minimum suction pressure at port S must also not fall below 0,8 bar absolute during operation and during cold start.

Installation position

See the following examples 1 to 4.

Further installation positions are possible upon request. Recommended installation position: 1 and 2.

Below-tank installation (standard)

Below-tank installation is at hand if the axial piston unit is installed below the minimum liquid level outside the tank.

General project planning notes

The axial piston unit is designed to be used in open circuits. The project planning, installation and commissioning of the axial piston unit require the involvement of qualified skilled personnel. Before using the axial piston unit, please read the corresponding instruction manual completely and thoroughly. If necessary, request it from Bosch Rexroth. Before finalizing your design, request a binding installation drawing. The specified datas and notes must be observed. Preservation: Our axial piston units are supplied as standard with preservative protection for a maximum of 12 months. If longer preservative protection is required (maximum 24 months), please specify this in plain text when placing your order. The preservation times are valid under optimal storage conditions. Details of these conditions can be found in the data sheet 90312 or the instruction manual. A pressure relief valve is to be provided in the hydraulic system. Observe the instructions in the instruction manual regarding tightening torques of connection threads and other threaded joints used. The notes in the instruction manual on tightening torques of the port threads and other screw joints must be observed. The ports and fastening threads are designed for the permissible maximum pressure pmax (see instruction manual). The machine or system manufacturer must ensure that the connecting elements and lines correspond to the specified operating conditions (pressure, flow, hydraulic fluid, temperature) with the necessary safety factors. The working ports and function ports are designated only to accommodate hydraulic lines.

Notes on suction line

Keep as short and straight as possible, without bend Use a supporting ring for plastic hoses Use two hose clamps to protect the suction hose against air suction Note pressure resistance of suction hose compared to ambient pressure

Replacing seals

The O-rings used as seals to prevent air from entering the suction line are to be replaced after every removal and new installation in order to guarantee complete sealing.

Material number for O-rings

R909083796: O-ring for suction stud G3/4 R909083802: O-ring for suction stud G1 R909083808: O-ring for suction stud G1¼

Coupling flange

There are special, modified coupling flanges in 4-hole and 6-hole design for the cardan shaft drive.

The coupling flange is not included in the scope of delivery and must be ordered separately.

4-hole coupling flange, complete – ⌀90 mm

Material number: R902060152

6-hole coupling flange, complete – ⌀100 mm

Material number: R902060153

Notes

Assembly of the coupling flange is carried out by pulling onto the drive shaft with the aid of the threaded bore in the drive shaft end. The coupling flange must be clamped on the drive shaft using a socket-head screw. In addition, permanent lubrication should be applied between the drive shaft and the coupling flange. The socket-head screw should be secured in a suitable manner (e.g. gluing with Loctite 276) and tightened with a tightening torque of 130 Nm. Sudden axial impact upon the drive shaft will lead to rotary group damage and therefore must be strictly avoided.

During and shortly after operation, there is a risk of burns on the axial piston unit. Take appropriate safety measures (e.g. by wearing protective clothing).
