The A.O. Smith 326PI34 motor, widely used in commercial and industrial applications, is recognized for its reliability and efficiency. Whether your motor has worn out or you’re considering a replacement for improved performance, understanding the replacement process is essential. This article will cover the features of the 326PI34 motor, how to identify compatible replacements, and step-by-step guidance on replacing this motor with the best alternatives available today.
Understanding the A.O. Smith 326PI34 Motor Specifications
The 326PI34 motor is part of the robust series produced by A.O. Smith, a brand now managed under Century Motors after A.O. Smith’s acquisition by Regal Beloit. Motors like the 326PI34 are commonly used in water pumps, HVAC systems, and other industrial settings due to their durability and performance under continuous operation.
Typical specifications for the 326PI34 include:
- Horsepower: Generally ranging from 1 to 1.5 HP.
- Frame Size: Often a 48 or 56 frame, important for fit compatibility.
- Voltage and Amperage: These motors often run on standard voltages (e.g., 115/230V) but check specifics to match the system.
- RPM: Commonly operates at 3450 RPM, a standard for many pumps and industrial setups.
- Enclosure Type: Many A.O. Smith motors come with a Totally Enclosed Non-Ventilated (TENV) housing, which is designed to withstand environmental wear by preventing dirt and moisture from reaching internal components.
Finding a Compatible Replacement Motor
Finding a replacement for the 326PI34 requires an understanding of frame sizes and specifications. Century (formerly A.O. Smith) offers replacement motors compatible with many older models, including the 326PI34, and many distributors provide pre-wired options to make installation easier.
Steps to Identify a Compatible Motor:
- Check Frame Size: The A.O. Smith 326PI34 usually aligns with 48 or 56 frames, though it’s essential to verify since frame sizes determine the mounting.
- Match Horsepower and RPM: For similar performance, ensure that horsepower and RPM match the original motor’s specs. Century offers options in 0.75 to 1.5 HP with standard RPM ranges.
- Confirm Voltage Compatibility: Double-check that your system voltage aligns with the motor’s specs, especially if you’re switching brands or considering minor model variations.
Popular replacement models often include A.O. Smith’s own replacement motors or motors from Century, which continue the A.O. Smith design standards. Authorized sellers like Grainger or Boat Lift Warehouse provide replacement options that can be matched to specific applications.

Step-by-Step Guide to Replacing the A.O. Smith 326PI34 Motor
Replacing an industrial motor requires some mechanical skill, and taking time to prepare can streamline the process. Here’s a step-by-step guide:
Step 1: Gather Tools and Safety Gear
- Basic tools include a wrench set, screwdriver, and voltage tester.
- For safety, use insulated gloves and ensure the power source is disconnected before beginning.
Step 2: Disconnect the Existing Motor
- Turn off the power and lock out the breaker to prevent accidental energizing.
- Disconnect the wiring by noting the wire connections or photographing them for reference. Use a voltage tester to confirm there is no residual power.
Step 3: Remove the Motor from its Mounting
- Loosen the mounting bolts holding the motor frame in place.
- Carefully remove the motor and keep any hardware that may be reused for the new installation.
Step 4: Install the New Motor
- Mount the replacement motor onto the same bracket, ensuring it aligns with any necessary components.
- Follow the provided wiring diagram for proper electrical connections, referring to your photos or notes for any customized wiring setups.
- If the motor is pre-wired by the supplier, follow their connection guidelines.
Step 5: Test the Installation
- Reconnect the power source and run a test cycle to verify smooth operation.
- Check for any unusual noises or vibrations. If you notice any issues, double-check all connections and mounting points.
