WABCO HABS-E ABS Pump Motor – Replacement Motor Kit
Restore reliable hydraulic ABS pump operation with this replacement motor for WABCO HABS-E hydraulic ABS systems.
The motor is the drive component responsible for operating the hydraulic pump within the ABS modulator. When the motor becomes worn, fails to operate, or cannot generate the required hydraulic pump activity, the ABS system may be unable to properly build or maintain hydraulic pressure during an ABS event.
This replacement motor provides a practical alternative to replacing the complete ABS modulator when the motor itself is the failed component.

Why Replace the Motor?
The electric motor is a critical component of the hydraulic ABS system. If the motor fails, the hydraulic pump cannot perform its required function, potentially disabling important ABS hydraulic functions.
Replacing the motor can allow the original hydraulic assembly to remain in service rather than replacing the complete modulator.
Important Installation Note
Verify the existing motor, ABS modulator configuration, and part number before ordering. 4784079472 is specifically associated with the WABCO HABS-E application listed above.
For professional installation, follow the applicable WABCO service and repair procedures.
