The Wacker Neuson Camshaft Shim White is a genuine OEM component designed for CRT48-25K and CRT36-23K series ride-on concrete trowels, including both low-speed and high-speed configurations. As a genuine Wacker Neuson part, the is manufactured to the same tolerances and material specifications as the original, ensuring correct camshaft end-play adjustment right out of the box. This white-coded shim is a precision fit for the CRT48-25K-L, CRT48-25K-H, CRT36-23K-H, and CRT36-25K-H trowel models. When you need to restore proper valve timing and camshaft positioning, using the correct OEM shim is the most direct path to a properly running trowel.
Key Features
- Color-Coded Thickness Identification — The white color designation makes it straightforward to select the correct shim thickness during camshaft end-play adjustment, eliminating guesswork on the workbench.
- Genuine OEM Dimensional Accuracy — Manufactured to Wacker Neuson's original tolerances, this shim maintains the precise axial clearance the camshaft requires for consistent valve actuation and engine performance.
- Direct Replacement for CRT Series Ride-On Trowels — Confirmed fitment for CRT48-25K-L, CRT48-25K-H, CRT36-23K-H, and CRT36-25K-H models — covering both 48-inch and 36-inch ride-on trowel platforms in low- and high-speed variants.
- Supports Correct Valve Timing — A worn or incorrect shim allows camshaft end-play to drift outside specification, leading to erratic valve timing, rough running, and accelerated wear on the camshaft and bearing surfaces.
- Engine Integrity Under Sustained Troweling Loads — Ride-on trowels run for extended finishing cycles under continuous load; a correctly shimmed camshaft helps the engine maintain consistent output and resist premature internal wear.
A camshaft shim is a thin, precision-ground spacer positioned along the camshaft to control its axial (end-to-end) movement within the engine. By limiting how far the camshaft can shift side to side, the shim keeps valve timing events consistent and prevents metal-to-metal contact between the camshaft and adjacent engine components. When this shim wears, becomes damaged, or is set to the wrong thickness, camshaft end-play increases — causing uneven valve operation, increased internal engine noise, and, if left uncorrected, damage to the camshaft journals and bearings. Replacing it with the correct color-coded OEM shim restores the manufacturer's specified clearance and brings the engine back into proper operating condition.
