Replacement Bearing Shaft PP3738G

The Dayton PP3738G is a direct-replacement bearing shaft engineered for Dayton pump models 5UWF3, 5UWF4 and 5UWF6. It restores the rotating assembly in compatible units so the pump returns to service without a full housing change. Maintenance teams and facility engineers use it to extend the life of existing Dayton pump installations.

Press-fit installation with alignment critical

Installation requires pressing the shaft into the bearing bore and coupling it to the impeller. The main risk is misalignment during the press, which creates run-out that leads to vibration, seal wear and premature bearing failure. A clean work area, proper press tools and a dial-indicator check after assembly prevent the most common rework.

Steady operation under continuous duty

Once correctly fitted, the shaft transmits torque smoothly during prolonged pump cycles. It maintains concentric rotation as the motor loads and unloads, keeping seal faces parallel and bearing temperatures stable. The component is not designed for shock-loading or dry-running conditions that exceed the original pump's operating envelope.

Questions about this item

How can I confirm the PP3738G bearing shaft is installed correctly on my Dayton pump?

After fitting the shaft onto the 5UWF3, 5UWF4 or 5UWF6 model, rotate it by hand; it should turn smoothly without binding or excessive play, and the pump should run quietly when powered.

What comes in the box with the PP3738G and what must I supply separately?

The package contains only the bearing shaft itself; you will need to provide any retaining rings, seals, lubricant or tools required for your specific pump reassembly.

Which compatible Dayton pump models does the PP3738G fit?

This bearing shaft is designed for Dayton pump models 5UWF3, 5UWF4 and 5UWF6; match the model number on your pump’s nameplate to one of these three before ordering.
