Wacker Neuson 5000117362 Ext. 1 Shaft Retaining Ring

The Wacker Neuson Ext. 1 Shaft Retaining Ring is a genuine OEM component designed for the CRT48 and CRT36 series ride-on concrete power trowels. Sourced directly from Wacker Neuson, this retaining ring meets the exact dimensional and material specifications required for proper shaft retention in these machines. Fitment covers a wide range of CRT48 and CRT36 models, including the CRT48-35L, CRT48-35V, CRT48-33K, CRT48-57K, CRT48-37V, CRT36-23K-H, CRT36-24A-H, and CRT36-25K-H, among others. Keeping this ring in good condition is critical to maintaining correct shaft positioning and preventing premature wear to surrounding drivetrain components.

Key Features

• Genuine OEM Dimensional Accuracy — Manufactured to Wacker Neuson's exact groove-width and diameter tolerances, ensuring the ring seats securely and holds shaft position without play.
• Drop-In Shaft Replacement — Designed to snap into the existing retaining groove on the Ext. 1 shaft with no modification to the housing or shaft assembly.
• Broad CRT Series Coverage — Fits a wide range of 48-inch and 36-inch Wacker Neuson CRT ride-on trowel models, including power steer, dual-fuel, electronic steering, and high-speed variants.
• Prevents Shaft Migration — A correctly installed retaining ring locks the shaft axially, preventing lateral movement that can cause bearing damage, uneven rotor wear, or trowel arm misalignment during finishing passes.
• OEM Parts Traceability — As a genuine Wacker Neuson part, 5000117362 carries full OEM part number traceability, supporting accurate service records and equipment maintenance documentation.

A retaining ring is a small but essential fastening component that clips into a machined groove on a shaft to prevent axial movement — meaning it stops the shaft from sliding back and forth within its housing. On a ride-on concrete trowel like the CRT series, shaft alignment is critical to the smooth, consistent rotation of the trowel arms across the concrete surface. When a retaining ring wears, deforms, or fails entirely, the shaft can shift under load, placing unintended stress on bearings and surrounding components and causing vibration, uneven finishing, or accelerated drivetrain wear.
