The Wacker Neuson Top Cover Shim.009, Green is a genuine OEM shim designed for CRT36 and CRT48 series ride-on concrete power trowels. Sourced directly from Wacker Neuson, this shim delivers the precise thickness specification required to maintain correct top cover clearance across a wide range of CRT models. Compatible fitment spans the CRT36-24A, CRT36-25, CRT36-26A, CRT48-31V, CRT48-33K, CRT48-34V, CRT48-35L, CRT48-35V, CRT48-37V, CRT48-57K, and related variants, including high-speed, power-steer, dual-fuel, and EU-spec configurations. As a genuine Wacker Neuson part, the is manufactured to the exact material grade and dimensional tolerance called out in the original engineering specification.
Key Features
- OEM Thickness Accuracy — Color-coded green and ground to a .009 in. nominal thickness, ensuring the shim delivers the exact stack height required by the original design.
- Drop-In Top Cover Fitment — Engineered to seat correctly within the top cover assembly without machining or adjustment, matching the original shim profile.
- Broad CRT Series Coverage — Fits CRT36 and CRT48 ride-on concrete trowel families, including high-speed, power-steer, dual-fuel, electronic-steering, and EU-spec variants.
- Critical Clearance Control — Maintains the designed operating clearance at the top cover; incorrect shim thickness can lead to binding, accelerated wear, or improper blade pitch response.
- Genuine Wacker Neuson Part — Supplied as an authentic OEM component, confirming material grade, hardness, and dimensional spec match the unit it replaces.
A top cover shim is a precision spacer used to set and maintain the correct axial or radial clearance within the gearbox or rotor assembly of a ride-on concrete trowel. By controlling this clearance, the shim ensures that rotating components operate with the correct amount of play — too much gap allows unwanted movement that causes wear and imprecise blade pitch control, while too little gap can cause binding and heat buildup. When the shim wears thin or is installed at the wrong thickness, operators will notice inconsistent blade pitch response, increased vibration, or premature wear on adjoining components, all of which compromise the quality of the finished concrete surface.
