5.3 Accessory installation instructions:

Motor Assembly:
- While assembling the motor onto the gear unit, the
coupling must be lubricated with a thin layer of grease
or with a no-grip lubricant.
- Carefully insert the motor shaft into the coupling and
make sure that the motor spigot perfectly matches
the gear unit spigot.
- After checking that the motor is properly centered,
tighten all the attachment bolts applying the torque
indicated in paragraph 9..3.
ATTENTION: when using aluminum and gray cast
iron motor flanges, the minimum allowable class for
the bolts is 5.8.; for nodular cast iron, the minimum
allowable class is 8..8..
NOTE: it is recommended to protect the hydraulic
motors and their connections so that they are not
damaged by rough ground during normal work
operations.
