1.3 Functional description
Fig. 1 The COMPACT CBP 140
Hägglunds hydraulic industrial motor COM-
PACT CBP is of the radial-piston type with
a rotating cylinder block/hollow shaft and a
stationary housing.The cylinder block is moun-
ted in fixed roller bearings in the housing. An
even number of pistons are radially located in
bores inside the cylinder block, and two valve
plate directs the incoming and outgoing oil to
and from the working pistons. Each piston is
working against a cam roller.
When the hydraulic pressure is acting on the
pistons, the cam rollers are pushed against the
slope on the cam ring that is rigidly connected
to the housing, thereby producing a torque.The
cam rollers transfer the reaction force to the
piston which are guided in the rotating cylinder
block. Rotation therefore occurs, and the torque
available is proportional to the pressure in the
system.
Oil main lines are connected to ports A and C
in the connection blocks and drain lines to ports
D1, D2, D3 or D4 in the motor housing.
The motor is connected to the shaft of the
driven machine through the hollow shaft of
the cylinder block.The torque is transmitted
by splines.

Technical data
2. TECHNICAL DATA
There are three distinct cases:
Case 1:
The motor works in braking mode. Required
charge pressure at the inlet port is according
to diagram below.
Case 2:
The motor works in driving mode only. Required
back pressure at the outlet port corresponds to
30% of value given in diagram below, but may
not be lower than 2 bar (29 psi).
Case 3:
The motor is used with 2-speed valve. Requi-
red charge pressure at inlet port for valve is
according to AC-3.1 Accessories.
The hydraulic system must be such that the
motor will recieve sufficient charge pressure at
the low-pressure port. This applies to all types
of installations.
Note:
The diagram is valid for 1 bar (15 psi) case pressure. With increasing case pressure the charge
pressure must be increased accordingly. The graph is valid when 8 ports are used. Max casing
pressure is 3 bar (43,5 psi)(for 1% of the operation time evenly divided, pressure peaks of max 5
seconds upto 8 bar (116 psi) is allowed). Max permitted case pressure at stand-still is 8 bar (116
psi).

2.2 Sound from a complete installation
Hydraulic motor
The hydraulic motor is a known noise level.
(Tables of sound data - see subsection 4.9 in
the Engineering Manual).
Driven unit
The driven unit is an unknown sound source
(for us) but can through certain information
probably be obtained from the supplier. When
securing the torque arm of a hydraulic motor to
the foundation or casing of a driven machine,
it is highly important to study the construction
of the foundation or casing. This may well be
the most important factor to consider, since
many structures may give rise to resonance,
resulting in severe noise problems.
Remarks:
Background noise
The background noise can not normally be
influenced but is usually known or easy to
measure.
Pump unit
The pump unit is a known noise level.
Pipe noise
The pipe noise is probably the source of the
majority of mistakes in installations: all pipe
clamps should be of vibration insulating type
secured to concrete ceiling, wall or floor.
Securing to non-rigid metal structures or
structures is likely to give resonance and
should be avoided.

2.3 Choice of hydraulic fluid
The Hägglunds hydraulic motors are primarily designed to operate on conventional petroleum
based hydraulic oils. The hydraulic oil can be chosen in consultation with the oil supplier of your
local sales office, bearing the following requirements in mind:
GENERAL
The oil shall have FZG (90) fail stage minimum 11 described in IP 334 (DIN 51354).The oil must also
contain inhibitors to prevent oxidation, corrosion and foaming. The viscosity of mineral oil is highly
dependent of the temperature. The final choice of oil must depend on the operating temperature
that can be expected or that has been established in the system and not in the hydraulic tank.
Fire resistant fluids
OPERATING WITH FIRE RESISTANT FLUIDS
The following fluids are tested for Hägglunds motors: (ISO/DP 6071)
* Many hydraulic fluids with VI-improvers are subject to temporary and permanent reductions of the viscosity.
** Low viscosity gives reduced basic rating life for the motors and
reduction of max. allowed power for "COMPACT CBP".
IMPORTANT!
Down rating of pressure data and service life must be considered when using fire
resistant fluid. The Hägglunds company or its authorised representative must always
be contacted for approval in the case of these types of fluids.
RECOMMENDED VISCOSITY AT
OPERATING TEMPERATURE
40-150 cSt/187-720 SSU.
High temperatures in the system greatly reduce
the service life of oil and rubber seals, as well
as resulting in low viscosity, which in turn
provides poor lubrication.
Content of water shall be less than 0,1%.
In Industrial applications with high demands
for service life, the content of water shall be
less than 0,05%.
* Must be specified in the order.

Environmentally acceptable fluids
Explanation of
"GRADE OF FILTRATION"
Grade of filtration β10=75 indicates the
following:
β10 means the size of particle ≥10µm that will
be removed by filtration.
=75 means the grade of filtration of above
mentioned size of particle. The grade of
filtration is defined as number of particles in
the oil before filtration in relation to number of
particles in the oil after filtration.
Ex. Grade of filtration is β10=75.
Before the filtration the oil contains Nnumber
of particles ≥10µm and after passing the filter
once the oil contains number of particles
≥10µm.
This means that number of
particles have been filtered (=98,6%).
* Vegetable fluids give good lubrication and small change of viscosity with different temperature. Vegetable fluids
must be controlled every 3 months and temperature shall be less than +45° (113°F) C to give good service life for
the fluid.
** Environmental acceptabel fluid gives the same servicelife for the drive, as mineral oil.
Technical data
Filtration
The oil in a hydraulic system must always be
filtered and also the oil from your supplier has
to be filtered when adding it to the system.
The grade of filtration in a hydraulic system is
a question of service life v.s. money spent on
filtration.
In order to obtain stated service life it is
important to follow our recommendations
concerning contamination level.
When choosing the filter it is important to
consider the amount of dirt particles that the
filter can absorb and still operate satisfactory.
For that reason we recommend a filter with an
indicator that gives a signal when it is time to
change the filter cartridge.
Filtering recommendations
Before start-up, check that the system is
thoroughly cleaned.
1. In general the contamination level in our
motors should not exceed ISO 4406 19/15.
(NAS 10)
2. For heavy-duty industrial applications the
contamination level should not exceed ISO
4406 16/13. (NAS 7)
3. When filling the tank and motor housing, we
recommend the use of a filter with the grade
of filtration β10=75.

3. INSTALLATION
3.1 Mounting instructions
If the motor is to work properly it must be instal-
led with the greatest possible precision. Every
item connected to the motor that does not meet
the requirements of the following instructions
may result in stresses that adversely affect the
service life of the motor.
Normally the motor must be completely filled
with oil. When the motor is installed with the
shaft in the horizontal plane, the drain ports
must be positioned vertically.The higher of the
two drain ports must be used: see fig. 3.25.
When the motor is mounted with the shaft in
the vertical plane, drain outlet D1, D2, D3 or
D4 must be connected to the drain hole on the
shaft end housing or end cover. A preloaded
check valve must be connected in the drain line
to ensure that the motor is filled with oil; see
3.2.2 "Draining and venting the motor".
The drain line must be dimensioned so that
max. 3 bar (43.5 psi) motor housing pressure
is not exceeded.

The max housing pressure is 3 bar (43.5 psi).
Brief peaks during operation up to 8 bar (116
psi) are permissible. The permitted housing
pressure when the motor is stationary is 8 bar
(116 psi).
The motor must always be connected in such
a way as to give a sufficient boost, make-up
flow at the low pressure connection. This is
particularly important at high speeds and
with rapid reversing, see 2.1 "Recommended
charge pressure".
Spline
The splines shall be lubricated with hydraulic
oil, or filled with transmission oil from the con-
nected gearbox. To avoid wear in the splines,
the installation must be within the specified
tolerances in fig. 3.3.If there is no radial or axial
force on the shaft, the shaft can be oiled only.
For production of the shaft, see 078 0150,
078 0162, 078 0163 and 278 5023, 278 5024,
278 5025, 278 5026. For control of spline see
table 3.3.

Installation and Maintenance Manual, Compact CBP
Thread for mounting tool
To make it easier to mount the motor on the
driven shaft end or to remove the motor from
the shaft it is recommended that a hole (Table
3.4) should be drilled and tapped in the centre

3.1.3b Fitting the double ended torque arm
The torque arm is fitted to the motor before the
motor is mounted on to the driven shaft. See
3.1.3a "Fitting the torque arm to the motor".
Alt. 1:
Check and adjust the rod end (pos 1) according
to the drawing. Mount the rod to the torque arm,
use the shaft (pos 2) and lock them with circlips.
Tighten the 4 pcs of screw (pos 3) on the rod
end, Torque according to table 3.7b.
Mount the hydraulic cylinder. The piston rod
has to be mounted upwards, and on the right
hand viewed from the motors main connection
side. Cylinders oil connection A, B and C must
point in the direction to the motor. Mount the
hoses.The hose mounted to the high pressure
connection (C) has to be mounted to the
hydraulic cylinders connection B, and the hose
from connection (A) has to be mounted to the
cylinders connection A.
This is valid with the cylinder on the right side
hand-side of the the motor, and a single speed
motor.
Remark!
Start the system and run it for some minutes.
Vent the cylinder from air. Use the vent screws
on the cylinder (pos 4).

3.1.4a Mounting the motor onto the driven shaft
The motor can be mounted onto the driven shaft with or without a mounting tool, but the use of a
mounting tool is recommended since it makes the work easier.
Mounting the motor with a mounting tool (Fig. 3.10)
- Remove the End cover together with screws and washers.
- Align the motor with the driven shaft.
- Locate the existing plastic washer between the nut on the mounting tool and the bearingretainer.
Pass the mounting tool through the centre of the motor, and screw it into the driven shaft to stated
depth by using the key handle in the end of the tool.
- Pull the motor onto the shaft by turning the nut on the mounting tool.
- Remove the mounting tool.
- Refit the plug.
- Refit the end cover and tighten the screws together with washers. Torque 81 Nm (59 lbf·ft) for
CBP 140, and torque 125 Nm (91 lbf·ft) for CBP 280-840.
