The connecting threads on the motor are covered with factory-attached pro‐
tective caps. These protective caps must only be removed immediately be‐
fore screwing in the coolant lines or the quick coupling in order to prevent dirt
from entering the cooling system.

Tab. 6-6: Cooling connection thread, permissible tightening torques and
screw-in depths
NOTICE
The allowed motor connection tightening torque may not be exceeded! If the
tightening torque or screw-in depth is exceeded, the motor may be damaged
irreversibly.
The coolant connections on the motor side are provided for coolant connec‐
tion threads with axial sealing.
Bosch Rexroth recommends to use threaded connections which contain an
O-ring for axial sealing of the screw connections.
For example, seals consisting of hemp, teflon tape or cone-shaped screw
connections are not considered to be suitable, since this type of seal may
stress the connection thread at the motor to an unreasonably high extent
and/or damage it permanently.
The machine manufacturer is responsible for ensuring that the
coolant connection is tight and for verifying and accepting the
tightness after the motor has been installed.
Additional, regular inspections to ensure proper condition of the
coolant connection should be logged in the maintenance sched‐
ule of the machine.
It is also possible to use a quick coupling for the coolant port. The quick cou‐
pling features leak protection on either side and can be released even under
full pressure.
