The following troubleshooting table 7 may assist you in troubleshooting. The table
does not claim to be complete.
In practice, problems may arise that cannot be considered here.
15.1 TROUBLESHOOTING PROCEDURE
f Even when under time pressure, proceed in a systematic and targeted manner.
Random and unplanned disassembly and adjustment of individual values can
make it impossible to determine the original cause of a malfunction.
f Get an overview of the planetary gearbox operation in connection with the
machine or vehicle.
f Try to clarify whether the planetary gearbox has performed the required
function in the machine or vehicle before the error occurred.
f Try to understand the changes of the machine, vehicle where the planetary
gearbox is installed:
– Were there changes in the conditions of use or the area where the gearbox
was deployed?
– Has maintenance work been performed recently? Does an inspection or
maintenance log exist?
– Have changes (e.g. conversions) or repairs been performed on the overall
system of the planetary gearbox? If yes: What were these?
– Has the lubricating oil or the hydraulic uid been changed?
– Has the gear unit or the machine, the vehicle been operated in accordance
with the intended purpose?
– How is the malfunction evident?
f Gain a clear picture of what caused the malfunction. As necessary, ask the
direct operator.
f If appropriate, record the situation as you encountered it by taking digital
photographs and send these to Rexroth Service.
