13. Loosen the supply lines of the axial-piston motor. Proceed as described in the
machine/vehicle operating instructions or the operating instructions of the axial-
piston motor.
14. Seal the hydraulic lines on the axial-piston motor using the appropriate plugs.
15. If a static multiple-disk parking brake is included in the scope of supply, loosen
the brake release line on the planetary gearbox. The corresponding connections
are shown and labeled in the planetary gearbox dimensioned drawing in
appendix D "Technical data / Drawings" of the material number-specific
operating instructions.
16. Close the brake release connection 4 at the planetary gearbox with a
corresponding screw plug according to the parts list. For this, observe
appendix E "Parts list" of the material number-specific operating instructions.
17. Loosen the connections of all units and mounting parts that are required for
planetary gearbox operation. Observe the instructions on the planetary gearbox
dimensioned drawing in appendix D "Technical data / Drawings" of the material
number-specific operating instructions.
18. Protect the supply lines against contamination.
19. Make sure that neither dirt nor foreign substances penetrate in the lines or the
planetary gearbox.
20. If necessary, the axial-piston motor has to be removed from the planetary
gearbox before disassembling the planetary gearbox.
21. For the weight of the axial-piston motor, refer to the operating instructions of
the axial-piston motor manufacturer.
22. Attach the axial-piston motor carefully on an appropriate lifting equipment using
appropriate means of attachment, e.g. crane hook.
23. Tighten the means of attachment without lifting the axial-piston motor.
24. Loosen and remove, depending on the axial-piston motor model, the two to four
motor fastening screws 3 on the planetary gearbox.
25. Remove the axial-piston motor from the planetary gearbox fitting.
26. Pay attention when dismantling the axial piston motor, make sure that the
engaging carrier is not pulled out of the disk toothing of the static multiple-
disc parking brake.
27. Put the disassembled axial-piston motor down. For this, observe the operating
instructions of the axial-piston motor.
28. Remove all means of attachment and lifting equipment from the axial-piston
motor.
