Bosch Rexroth Mellansel AB, Installation and maintenance manual, Hägglunds CA 10 - CA 40, RE 15354-WA/04.2015

8 Commissioning

Dirt particles!
A not run-in motor in combination with dirt particles in the oil can badly affect the
sliding surfaces in the motor. This is valid during the first 100 hours.
▶ The Hägglunds radial piston hydraulic motor must be installed and commisioned
in a clean condition.
8.1 Commissioning
Check the following points before commissioning the motor, i.e. before starting the
first time:
• Make sure that all fluids has been removed from the motor to prevent accidental
mixing with the hydraulic fluid used in the system.
• Check that the motor is connected to give the correct direction of rotation, see
7.3.5: Hydraulic ports and 7.3.6: Direction of rotation of motor shaft.
• Select the hydraulic fluid in accordance with the recommendations, see 15.1.4:
Hydraulic fluids and data sheet RE 15414, Hydraulic fluid quick reference.

8.1.1 Oil filling

1. Fill the motor housing with hydraulic fluid via a filter into the drain outlets D1,
D2 or the vent hole (depending on how the motor is mounted), see Table 5: Oil
volume.
2. Check the drain line to ensure that excessive pressure does not build up in the
motor case; see chapter 7.2: Installation conditions and 7.3.3: Draining and venting
the motor.
3. Check that the motor is protected from overloads, see chapter 15.1.1: Motor data.
4. Check that the charge pressure conforms to the charge pressure curve, see
chapter 15.1.2: Recommended charge pressure.
5. Check that all hydraulic couplings and plugs are properly tightened to prevent
leakage.
