R0527000 Engine & Wheel Ball Bearing Replacement - Pack of 2

Key Features

• Precision-Engineered Low Friction: Designed with high-quality stainless steel internal ball bearings to ensure the directional control engine and wheel axles rotate with minimal resistance, maximizing the cleaner's torque and speed.
• Corrosion-Proof Materials: Specifically manufactured from chemical-resistant polymers and stainless steel to withstand constant exposure to chlorine, salt, and varying pool pH levels without rusting or seizing.
• Double-Sealed Protection: Features a reinforced shield to keep out fine sand, silt, and plaster dust, which are the leading causes of bearing failure in suction-side cleaners.
• Dual-Purpose Fitment: Engineered to the exact dimensions of the R0527000 standard, allowing it to function as either an engine drive bearing or a wheel axle bearing within the MX series chassis.
• High-Durability Design: Built to handle the high RPMs of the internal turbine engine while maintaining structural integrity over multiple pool seasons.

Replaces / Cross-Reference Part Numbers

• Primary Part Number: R0527000.
• Cross-References: R052700, 100-2051.
• Manufacturer Equivalents: Zodiac R0527000, Baracuda MX8/MX6.

Compatibility & Fitment

This bearing is a critical mechanical component for the Zodiac MX series of suction-side cleaners. Key compatible models include:

• Zodiac MX8: Fits the internal engine and all four wheel axle positions.
• Zodiac MX6: Compatible with the main engine drive and wheel assemblies.
• Zodiac MX8 Elite: Direct fit for the scrub-action Elite series drive system.
• Zodiac MX6 Elite: Standard replacement for the compact Elite series bearings.

When to Replace

• Cleaner Moving Slowly or Stalling: If the internal turbine spins but the wheels don't turn, one of the engine bearings is likely jammed with grit.
• "Clicking" or Grinding Noises: Audible mechanical distress during operation usually indicates that the internal stainless steel balls have flattened or rusted.
• Wobbly Wheels: If the wheels have significant side-to-side play on the axle, the bearing race has worn down and can no longer support the drive load.
• Directional Failure: If the cleaner only moves in one direction or fails to reverse, the directional control engine bearings are likely seized.

Installation Tips

• Check for Shaft Wear: PRO TIP: Before installing the new R0527000, inspect the plastic axle or engine shaft for grooves. If the shaft is worn down, the new bearing will not sit level and may fail quickly.
• Clean the Housing: Use a small brush to remove any sand or calcium buildup from the bearing seat. Even a small grain of sand can prevent the bearing from snapping into place correctly.
• Outer Race Pressure: When pressing the bearing into the wheel or engine pod, apply pressure only to the outer plastic rim. Pressing on the center can damage the internal ball alignment.
• Water Lubrication Only: These bearings are designed to be lubricated by pool water. Never apply grease, WD-40, or oil, as these will attract sand and lead to immediate failure.
