11 Removal and replacement
This chapter is not applicable to MCR-R type motors. For MCR-R refer to the
appropriate installation drawing and procedure.
11.1 Required tools
Removal can be performed with standard tools. No special tools are necessary.
11.2 Preparing for removal
1.
Decommission the entire system as described in the instruction manual for the
machine or system.
– Relieve pressure in the hydraulic system according to the instructions of the
machine or system manufacturer.
– Make sure that the relevant system components are not under pressure or
voltage.
2.
Protect the complete system against being energized.
3.
For applications where the motor is in a load bearing installation, ensure the
machine or connecting mechanism is fully supported and restrained from
uncontrolled movement.
11.3 Removing the radial piston motor
Proceed as follows to remove the radial piston motor:
1.
Ensure the hydraulic system is depressurized.
2.
Ensure the radial piston motor has been allowed to cool down.
3.
For below-reservoir installation, before disconnecting the radial piston motor,
isolate the connection to the reservoir or drain the reservoir.
4.
Place a drip tray under the radial piston motor to collect any hydraulic fluid that
may escape.
5.
Uncouple/unbolt the shaft of the radial piston motor from the the system or
machine ensuring any disconnected mechanism is restrained from uncontrolled
movement.
6.
Disconnect the hydraulic lines ensuring the escaping hydraulic fluid is collected in
the drip tray.
7.
Support the radial piston motor by use of a suitable lifting device. Remove
mounting bolts and lift the motor free of its installation and lower onto a suitable
level surface. Care should be taken with H type motors to ensure that internal
components are not allowed to fall free.
8.
Drain the radial piston motor.
9.
Plug all openings.
11.4 Preparing the components for storage or further use
▶
Proceed as described in chapter 6.2 "Storing the radial piston motor" on
page 27.
