Procedure
Bosch Rexroth AG, General Operating Instructions HYDROTRAC GFT 8000 series 40, RE 79022-01-B/04.2020
To connect the static multiple-disk parking brake to the hydraulic system:
1
Make sure that the installation point is free of dirt and foreign substances.
Make sure that neither dirt nor foreign substances penetrate in the brake
release connection. The brake release connection is shown and labelled in the
planetary gearbox dimensioned drawing in appendix D "Technical data /
Drawings" of the material number-specific operating instructions.
2
Remove the plug on brake release connection 5 of the planetary gearbox.
3
Connect the brake release line to the brake release connection 5.
4
Connect the static multiple-disk parking brake according to the hydraulic
diagram of the machine or vehicle manufacturer with the remaining hydraulics
system.
Observe, that the multiple-disk parking brake by planetary gearboxes with
internal brake release connection B
is connected to the hydraulic system of the machine/vehicle.
7.7 Performing a flushing cycle
Rexroth recommends to flush the planetary gearbox when changing the lubricating
oil type or the lubricating oil manufacturer as well as after carrying out a major
repair.
Before commissioning the axial piston motor, Rexroth recommends a rinsing run of
the entire system. Observe the information in the operating instructions of the
axial piston motor manufacturer.
The flushing cycle is to be performed using an additional flushing unit. Observe
the specifications of the flushing unit manufacturer for the exact procedure
when performing the flushing cycle.
7.8 Assembling mounting parts
If your planetary gearbox has additional mounting parts, you will find information
on them in the following documents, which are included in the material number-
specific operating instructions:
• Chapter "Scope of supply"
• Appendix C "Mounting parts"
• Appendix D "Technical data / Drawings"
• Appendix F "Optional equipment variant"
Connect all units, supply lines, and connections necessary for operating the
planetary gearbox and its mounting parts.
