Installation Instructions
Conditions of installation and application
An Application Data Sheet (ADS) is used to select the correct Black Bruin hydraulic
motor for each application. A filled and signed ADS is required for each motor model
and application to validate the motor manufacturer’s warranty. Always advise the
motor manufacturer or its representative, when selecting motors for exceptional
circumstances, like underwater applications, use with special fluids, etc.
Mounting the motor
The installation dimensions and tightening torques are given in the product
datasheet.
Check the following things for mounting the motor:
• The counter surfaces must be clean and even.
• Make sure that the strength class (grade) of the fastening screws is sufficient.
• Make sure that the fastening screws are of suitable size and length.
• The fastening screws should be cleaned and oiled lightly before installing them.
• Use threadlocker only if necessary, removing the old threadlocker may be difficult.
• Remove any old threadlocker before mounting the motor.
Note:
When replacing fastening screws with new ones, renew all of the screws.
Attention:
When using stud bolts, do not tighten the bolt. Tightening of the stud bolt
is done with the nut.

Flushing the hydraulic system
Prior to connecting the motor as part of the hydraulic system, the hydraulic circuit of
the motor must always be flushed by circulating hydraulic fluid through a filter
installed in place of the motor.
The flushing is carried out by circulating hydraulic fluid through the entire system
with a minimum pressure for at least an hour.
• After flushing, renew all filters.
Note:
Flushing the hydraulic system should also be performed after every
system modification or repair.
