Description
Restore the structural integrity and cleaning performance of your pressure-side pool cleaner with the Polaris 39-004 Bottom Housing Assembly. This genuine OEM replacement lower body shell is specifically designed for the Polaris 3900 Sport Pool Cleaner, providing the durable foundation that supports the cleaner's internal drive components, water management system, wheels, and chassis.
If your existing housing has become cracked, warped, or damaged from years of use, replacing it with the Polaris 39-004 can help restore proper alignment, smooth operation, and dependable cleaning performance.
Genuine Polaris OEM Quality
Manufactured by Polaris using the same premium materials as the original factory-installed component, the 39-004 Bottom Housing Assembly is built for an exact fit and long-lasting durability. Unlike aftermarket alternatives, this OEM replacement ensures proper compatibility with your Polaris 3900 Sport cleaner.
Supports Critical Cleaner Components
The bottom housing serves as the primary structural frame for your cleaner, securely holding the internal drive system, gearbox, wheel assemblies, and Water Management System (WMS). It also features the large center intake opening that allows dirt, leaves, sand, and other debris to be drawn into the filtration bag for efficient pool cleaning.
A damaged lower housing can affect cleaner alignment, wheel movement, and overall performance, making replacement essential when excessive wear or damage is present.
When Should You Replace the Bottom Housing?
Replacing the Polaris 39-004 Bottom Housing is recommended if:
- The housing is cracked, broken, or warped
- Mounting tabs or screw locations have become damaged
- Wheel, axle, or gearbox components no longer mount securely
- The cleaner drags, tracks improperly, or becomes misaligned
- Internal components no longer fit correctly due to housing wear
- The lower shell has sustained impact or stress damage

Directions
Easy Service & Installation
Before replacing the housing, turn off the booster pump and remove the cleaner from the pool.
Since this is the cleaner's primary structural component, carefully transfer all internal parts from the old housing into the new assembly while keeping hardware organized during disassembly. While the cleaner is open, it's also a great opportunity to inspect other wear components such as:
Gearbox
Wheel bearings
Wheels and tires
Seals
Water Management System (WMS)
After installation, verify that all wheels rotate freely and the cleaner moves smoothly without rubbing or binding.
