Polaris Genuine OEM Wheel Lock Screw 3-Pack, 48-036

Polaris 48-036 is the wheel lock screw for the Polaris 3900 and Polaris 480 pool cleaners. It is the genuine part, in metal, and it is the fastener that holds a wheel onto its axle.

Small part, whole cleaner

A cleaner that suddenly drags, turns in circles or leaves a wheel behind in the deep end has usually lost one of these. The screw works underwater against constant load and vibration, and when it backs out there is nothing holding the wheel on the axle.

Quantity

This is listed as a three pack, and the same part number also appears in supplier data sold individually. Given how easy the screw is to drop into a pool during a wheel change, having spares is not a bad outcome either way.
