Ryobi 89037011023 E-ring E8 Oem Lawn Mower Part

Product Description

The RYOBI 89037011023 is an OEM E-Ring E8 retaining fastener designed for use in RYOBI and RIDGID lawn mower equipment. E-rings, also called external retaining rings, seat into a groove on a shaft or pin to prevent lateral movement of rotating or sliding components. This type of fastener is a small but critical part of the drivetrain or blade engagement assembly, keeping components properly positioned during operation. Licensed technicians and experienced equipment service technicians install this type of part as a routine repair or maintenance replacement when the original ring is lost, deformed, or worn.

This E-Ring is intended for outdoor power equipment service on RYOBI and RIDGID branded lawn mowers. It fits into assemblies where a shaft or pin requires a low-profile, snap-on retaining solution. The E8 designation indicates the ring size classification, which corresponds to the shaft diameter it is designed to retain. This part is sourced as an original OEM component, meaning it meets the same dimensional and material specifications as the factory-installed part.

Key Features

• OEM part sourced directly from the original manufacturer for exact fitment
• E8 size classification for compatibility with the correct shaft diameter
• External retaining ring design seats securely in a machined shaft groove
• Prevents lateral component movement on rotating or sliding shafts

Compatibility

Installation Notes

Installation of this E-ring requires power equipment to be fully shut off and the spark plug wire disconnected before any disassembly. Snap-ring pliers or a small flat pick are the appropriate tools for seating and removing E-rings without distorting the ring. Ensure the shaft groove is clean and free of debris before installing the new ring. This type of repair is typically performed by small engine technicians or experienced equipment service professionals.
