Pentair EC55 Plastic Wheel Screw Replacement Automatic Pool Cleaner Set of 5

Buying Guide: Pentair EC55 Plastic Wheel Screw

The catalog lists EC55 as “Wheel Screw – Plastic,” item 31 on the Legend 4-Wheel LL105 parts list and item 29 on the Legend LL505G/LL505GG and Legend II LX5000 lists. A Polaris cross-reference entry maps it to C55.

How it differs from adjacent fasteners

The wheel area uses several other separately-numbered screws: EC40 (general screw), EA30 (screw for the EA40 shield and EC110 turbine cover), EU80 (cover-to-frame screw), and 370258Z (axle screw with lock washer). EC55 is specifically the plastic wheel screw; do not substitute another wheel-area fastener number.

What to confirm with the seller

• Color: white EC55 versus gray LLC55PM are separate catalog entries — match your cleaner’s color scheme.
• Diagram quantity differs by model (5 on the LL105 list, 4 on the LL505/LX5000 lists); these are per-cleaner counts, not pack sizes. The “set of 5” in this title should be confirmed with the seller.
• Hub caps (360005/360013) and wheel washers (EC64) are separate items and are not implied by EC55.
