Wacker Neuson 5000157808 Oversized Shim

The Wacker Neuson is a genuine OEM Oversized Shim designed for the CRT48-31V series 1220mm/48in ride-on concrete trowels. As a direct OEM replacement sourced through authorized channels, this shim is manufactured to the same tolerances as the original component it replaces, ensuring correct clearance and load distribution within the assembly. Fitment covers the CRT48-31V, CRT48-31V-H High Speed, CRT48-31V-E, CRT48-31V-ES, and CRT48-31V-ES-E variants, making the right call across the full CRT48-31V family.

Key Features

• Precision-Ground OEM Tolerancing — Manufactured to exact thickness specification so clearances and bearing loads remain within the design envelope of the CRT48-31V trowel.
• Oversized Profile for Corrective Fitment — The oversized designation means this shim is intended to restore correct spacing when wear has opened up clearances beyond the standard shim's range.
• Full CRT48-31V Family Coverage — Confirmed fitment across the standard, High Speed, Electronic Steering, and electric-start variants of the 1220mm/48in ride-on trowel line.
• Trowel Finish Quality Depends on It — Incorrect shim sizing causes rotor wobble and uneven blade pressure, leading to inconsistent surface finish on finished concrete slabs.
• Genuine Wacker Neuson OEM Part — Supplied as an original equipment component, carrying the correct part number 5000157808 for confident, accurate ordering.

A shim is a precisely sized spacer used to set or restore the correct gap between rotating or sliding components inside a mechanical assembly. In a ride-on concrete trowel like the CRT48-31V, shims control the axial and radial clearances that keep the rotor and drive components running true. When those clearances grow through normal wear, an oversized shim closes the gap back to specification, preventing vibration, uneven blade contact, and accelerated wear on surrounding components. Installing the wrong thickness allows slop in the drivetrain that shows up directly as a compromised finish on the concrete surface.
