Description

The Polaris 39-004 is the genuine bottom housing for the Polaris 3900 Sport pressure side cleaner. It is the lower half of the cleaner’s body, the piece the wheels, drive train and top housing mount to.

When you need it

A cracked or broken bottom housing usually shows up as a cleaner that sags on one side, binds on a wheel, or starts shedding small parts. Because everything else bolts to this housing, replacing it puts the cleaner back into alignment.

Before you order

This fits the 3900 Sport only. It is the housing by itself: wheels, tires, bearings and drive parts move over from the old housing. If the top housing is also damaged, Polaris sells the top housing assembly separately.
