Polaris 3900 Sport Front Axle Block Assembly (39-440)The front axle block assembly is a replacement part made by Polaris for the 3900 Sport. It is also made from the same high-grade materials used to make the original factory part. Making this a genuine OEM product you can trust.
This axle assembly was designed to be one of the two-axle assemblies needed to house the internal parts as well as external parts that aid in the maneuverability of the cleaner. Such parts are the wheel sprockets and spacers along with the ball bearings, chain, wheels, and a few other parts. When all combined, they give the cleaner the ability to move fast and efficiently along your pool surface.
This part is bolted to the bottom of the frame and is black with a metal extension that comes off the end. This ensures it has enough length to reach through the other parts and sets them firmly. They are attached by two pan head screws w/ washers which lock them into the frame ensuring no movement or impediment during the cleaning process.
