The Wacker Neuson is a genuine OEM Camshaft Shim Blue designed for CRT48-25K and CRT36-23K/25K series ride-on concrete trowels. As a direct OEM replacement, part is manufactured to the same tolerances as the original, ensuring the camshaft sits at the correct axial position within the engine. Compatible with both low-speed and high-speed variants of the CRT48 and CRT36 ride-on trowel families, this shim covers a broad range of machines in the Wacker Neuson CRT lineup.
Key Features
- OEM-Grade Shim Thickness Consistency — Manufactured to exact thickness tolerances so the camshaft maintains the correct end-play, preventing premature bearing and lobe wear.
- Color-Coded Blue for Correct Selection — The blue color designation identifies this shim's specific thickness grade, making service selection fast and accurate during engine assembly or rebuild.
- Direct Drop-In Fitment — Engineered to install exactly as the original component, with no reworking of mating surfaces or adjustment of related hardware.
- Broad CRT Series Coverage — Fits CRT48-25K low- and high-speed models (1220mm/48in) and CRT36-23K-H and CRT36-25K-H high-speed models (915mm/36in), covering the core Wacker Neuson ride-on trowel range.
- Engine Timing Integrity — A correctly fitted camshaft shim keeps valve timing within spec, supporting consistent trowel blade speed and smooth engine operation across the full duty cycle.
A camshaft shim is a precision-ground spacer placed at the end of the camshaft to control axial endplay — the small amount of side-to-side movement the shaft has within the engine block. Setting this clearance correctly is critical: too much endplay causes noise, accelerated bearing wear, and erratic valve timing, while too little can bind the shaft and damage the engine. On Wacker Neuson CRT ride-on trowels, where consistent engine output directly drives blade rotation speed and finishing quality, a worn or incorrect shim can translate to uneven surface results and costly engine damage if left unaddressed.
