6.3 Connecting the Cooling Water (only for MAF Motors)
Inflow (IN) and outflow (OUT) can be assigned at the user's dis‐
cretion. The assignment does not affect the performance data of
the motor.

On delivery, the connection threads at the motor are covered with protective
stoppers. These protective stoppers may only be removed shortly before the
coolant lines are screwed in or the quick-action couplings are removed to
avoid the intrusion of dirt into the cooling system.

Wrong tightening torques may destroy the
coolant connection threads on the motor!
NOTICE
Make absolutely sure not to exceed the permissible tightening torque of the
motor connections! Exceeding the tightening torque or depth of engagement
can lead to irreversible motor damage.
The motor-sided coolant connections are designed for coolant connection
threads with axial sealing.
Bosch Rexroth recommends to use connection threads which contain an O-
ring for axial sealing of the screw connection.
Sealing with hemp bred, teflon tape or conical screw unions is not considered
suitable as this kind of sealing can stress and/or even damage the connec‐
tion thread on the motor to an unreasonably high degree.
The machine manufacturer is responsible for the tightness of the
coolant connection and for testing and accepting it after installa‐
tion of the motor.
Furthermore, a regular test of correct condition of the coolant con‐
nection should be specified in the machine maintenance sched‐
ule.
Quick-action coupling Another coolant connection variant is the quick-action coupling. It has a leak
protection at both sides and can be released even under full pressure of the
coolant system.
If a motor having this coolant connection is ordered, all parts of the quick-ac‐
tion coupling are included in the motor delivery. The user can choose from
