C-55 C55 Wheel Screws and C64 Extra Washers Replacement - For 180/280 Polaris Pool Cleaner - 6 Pack

C-55 & C-64 Pool Cleaner Wheel Screw and Washer Replacement Kit

Key Features

• Shear-Point Safety Design: Specifically engineered as a "sacrificial" part to snap or shear off if the cleaner's wheel becomes jammed, protecting the expensive drive motor and internal gears from catastrophic damage.
• Corrosion-Proof Material: Manufactured from high-grade, UV-stabilized white plastic that is completely resistant to pool chemicals, salt, and constant water immersion, ensuring the screws won't rust or seize to the axle.
• Precision Threading: Features a standard Polaris-spec thread pitch designed to seat perfectly into the axle frame, preventing the wheels from wobbling or falling off during high-pressure operation.
• Integrated Washer Protection: Includes the essential C-64 washers which provide a low-friction barrier between the screw head and the wheel hub, reducing wear and allowing for smoother wheel rotation.
• High-Value Bulk Pack: Provided as a 6-pack of both screws and washers, giving you enough spares to handle a full wheel overhaul (usually 3 wheels) plus extra backups for future shearing incidents.

Replaces / Cross-Reference Part Numbers

• Wheel Screw: C-55, C55.
• Wheel Washer: C-64, C64.

Compatibility & Fitment

This hardware kit is designed specifically for the classic Polaris pressure-side cleaner chassis. Key compatible models include:

• Polaris 280: Fits the standard 3-wheel 280 model and the 280 TankTrax version.
• Polaris 180: Direct fit for the legacy 180 pool cleaner wheels and axles.
• Zodiac: Compatible with various private-label versions of the 280 cleaner manufactured by Zodiac Pool Systems.
• Note: CRITICAL: This kit is NOT compatible with Polaris 360 or 380 models. Those units use a different drive system and a larger, black plastic wheel screw (part number C-60).

When to Replace

• Sheared Screw Head: The screw has snapped off flush with the axle, usually caused by the cleaner getting stuck on a drain cover or stairs.
• Wobbly Wheels: If the wheel has excessive "play" or leans to one side, the screw may have loosened or the washer (C-64) has worn thin and lost its spacing.
• Missing Hardware: Wheel screws often fall out and get lost in the pool filter or debris bag if they aren't tightened correctly during routine maintenance.
• Brittle Plastic: If the screw heads are turning yellow or feel chalky to the touch, the plastic has become UV-damaged and is likely to snap under normal pressure.

Installation Tips

• The "Hand-Tight" Rule (PRO TIP): Do not use power tools or a heavy-duty screwdriver to tighten these screws. They are designed to be relatively fragile. Tighten them by hand with a large flathead screwdriver until they are just snug.
• Axle Inspection: Before installing a new C-55 screw, check the axle threads for debris or bits of the old broken screw. Use a small pick to clear the threads to ensure the new screw doesn't cross-thread.
• Washer Placement: Always ensure the C-64 washer is placed between the screw head and the wheel. If you omit the washer, the wheel will drag against the screw and may eventually unscrew itself while the cleaner is moving.
• Check the Wheel Bearings: While you have the screw off, spin the wheel on the axle. If it grinds or stops quickly, your wheel bearings (C-60) may also need to be replaced to restore full cleaning speed.
