Bosch Rexroth AB, Version 11.2019, RE 15305-WA
NOTICE
Contaminationofthehydraulicuid
The cleanliness of the hydraulic uid has a considerable impact on the
cleanliness and service life of the hydraulic system. Contamination of the
hydraulic uid could cause premature wear and malfunctions.
▶ Make sure that the working environment at the installation site is fully free
of dust and foreign substances in order to prevent contaminants, such as
welding beads or metal cuttings, from getting into the hydraulic lines and
causing product wear or malfunctions. The Hägglunds motor must be installed
in a clean condition.
▶ Use only clean connections, hydraulic lines and attachments (e.g. measuring
equipment).
▶ No contaminants may enter the connections when they are plugged.
▶ Before commissioning, make sure that all hydraulic connections are tight and
that all of the connection seals and plugs are installed correctly to ensure
that they are leakproof and uids and contaminants are prevented from
penetrating the product.
▶ Use a suitable lter system to lter hydraulic uid during lling to minimize
solid impurities and water in the hydraulic system.
Improper cleaning
Product can be damaged.
▶ Plug all openings with the appropriate protective equipment in order to
prevent detergents from entering the hydraulic system.
▶ Never use solvents or aggressive detergents. Use only water and, if necessary,
a mild detergent to clean the Hägglunds motor.
▶ Do not point the power washer at sensitive components, e.g. shaft seal,
electrical connections and components.
▶ Use lint-free cloths for cleaning.
Environmental pollution due to incorrect disposal
Careless disposal of the Hägglunds motor and its ttings, the hydraulic uid and
the packaging material could lead to pollution of the environment.
▶ Dispose of the Hägglunds motor, hydraulic uid and packaging in accordance
with the national regulations in your country.
▶ Dispose of the hydraulic uid in accordance with the applicable safety data
sheet for the hydraulic uid.
Escapingorspillinghydraulicuid
Environmental pollution and contamination of the ground water.
▶ Always place a drip tray under the Hägglunds motor when lling and draining
the hydraulic uid.
▶ Use an oil binding agent if hydraulic uid is spilled.
▶ Observe the information in the safety data sheet for the hydraulic uid and
the specications provided by the system manufacturer.
The warranty applies only to the delivered conguration.
The entitlement to warranty cover will be rendered void if the product is incorrectly
installed, commissioned or operated, or if it is used or handled improperly.

5 About this product
5.1 PERFORMANCE DESCRIPTION
The Hägglunds CA is a radial piston hydraulic motor that converts hydraulic ow
into mechanical rotation. Refer to product-specic data sheet and the order
conrmation for technical data, operating conditions and operating limits of the
specic CA motor.
5.2 PRODUCT DESCRIPTION
The Hägglunds CA is a radial piston hydraulic motor with a rotating cylinder
block shaft and a stationary housing. The cylinder block is mounted in xed roller
bearings in the housing. An even number of pistons are radially located in bores
inside the cylinder block, and the distributor 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 in the connection block and drain lines to
ports in the motor housing. The motor is connected to the shaft of the driven
machine through the cylinder block. The torque is transmitted by splines or shrink
disc coupling

DANGER
Unsecured motor can fall
Danger to life or risk of injury, damage to equipment.
▶ When in storage or during oil lling, the motor must always be secured from
falling.
NOTICE
Incorrect placement of the motor
Risk of damage to equipment.
▶ When in storage with shaft vertical, the motor must always be placed with the
hollow shaft facing down.
▶ It is also advisable to provide supports at the mounting surface of the motor,
see Fig. 11.
When the motor is placed on a at surface such as a oor, it must stand either on
its outer diameter or on the suitably protected end face of the hollow shaft. It is
also advisable to provide supports shown in Fig. 11.

more than 12 months in controlled environment, it must be totally lled with oil
according to below:
1. Place the motor as shown in Fig. 11, B) Standing with shaft vertical.
2. Fill the motor full with ltered oil containing a mixture of 2% Shell VSI 8235,
or similar compatible corrosion inhibitor in the selected uid in the following
order: D1, A1, C1.
NOTE! See Table 6 for oil volume.
3. Fit the plug to D1.
4. Seal connections A1 and C1 with the cover plates tted to the connection
surface at delivery. Check that the O-rings or rubber seals are in position in the
cover plates
5. Position the motor as shown in Fig. 11, A) Standing with shaft horizontal or alt.
