Maintenance
7-14 December 2016 CX 8105 - Ground Drive
Hydraulic Orbit Motor
The motor requires no maintenance itself.
It does, however, require clean oil so the tractor hydraulic
filters must be replace regularly.
Repair/Replacement
• Remove orbit motor from the fan.
Note: The shaft should never be hammered on or
forced in as this will result in motor damage
upon startup.
• Remove the snap ring and front cover.
• Push out the old shaft seal and press in the new one.
Note: The bearings should never be removed from
the shaft as they are pretensioned to the shaft
with the motor spinning.
• Replace the O ring.
• Both the O ring and shaft seal should be greased
with a “very clean” grease.
• Care must be taken when the front cover is installed
so the shaft seal is not damaged.
• Reinstall the snap ring.
• Fill the motor case with
“clean” oil before running.
Note: Any time a motor is replaced the case must
be filled with oil before it is started, if not, a
bearing failure could occur.
