Why is air bleeding important for Black Bruin hydraulic motors?
Unlike some hydraulic motor designs, Black Bruin rotating case motors do not automatically bleed air from the motor housing. Before operating the motor, manual air bleeding is therefore required. Air bleeding is required during initial installation and whenever the motor housing has been drained or opened for service or repair.
Air bleeding removes any trapped air and ensures that the motor housing is completely filled with hydraulic fluid. Operating the motor without proper air bleeding may result in insufficient lubrication and premature wear or damage to the motor. The air bleeding procedure details may vary by motor model, so always refer to the product-specific documentation for exact information.
Frequently asked questions
Where are the air bleeding screws located?
The air bleeding screws are typically located on the motor housing or hub cover, depending on the motor model. See the product datasheet for the exact location of the air bleeding screws on your motor. Multiple bleeding points allow air to be removed from the highest point of the housing in different motor installation positions.
What if feed pressure is not available?
Fill the housing manually with hydraulic fluid through the topmost opening of the motor housing.
How do I know when the motor housing is properly filled with hydraulic fluid?
The filling time depends on the motor size and volume, and the oil flow used during the procedure. Continue filling and bleeding the motor until only hydraulic fluid, with no air, flows from the air bleeding screw.
