⚠ Expert Installation & Field Note
Based on our shop experience specializing in heavy-duty brakes since 1985:
- Terminal Conversion: If swapping from a lead-wire to a stud-terminal configuration, ensure the connections are tightened to spec to prevent voltage drop during emergency activation.
- Seal Maintenance: We highly recommend replacing your Oval O-rings (SKU 277093288) when installing this motor to ensure a leak-free interface with the booster housing.
