Compatible models include the CRT48-31V, CRT48-31V-H, CRT48-31V-E, CRT48-31V-ES, and CRT48-31V-ES-E, covering the full range of 1220mm/48-inch ride-on trowel configurations. When you source part number, you can be confident you are getting the correct fit for your machine without guesswork.
Key Features
- Genuine OEM Throttle Control Integrity — Sourced directly from Wacker Neuson, this kit delivers the exact shaft geometry and material spec required for consistent throttle response on the CRT48-31V platform.
- Full CRT48-31V Series Coverage — Fits the standard, high-speed (CRT48-31V-H), electric (CRT48-31V-E), and electronic steering (CRT48-31V-ES / CRT48-31V-ES-E) variants of the 48-inch ride-on trowel.
- Kit Format for Complete Replacement — Supplied as a complete throttle shaft kit, so all necessary components for a proper throttle shaft service are included in a single order.
- Restored Engine Speed Control — A worn or damaged throttle shaft causes erratic engine response and inconsistent trowel rotor speed, directly affecting the quality of the finished concrete surface. This kit restores precise throttle actuation.
- OEM Part Number Verified — Part number 5000158142 cross-references directly to Wacker Neuson's own parts catalog, giving you confidence that this is the correct replacement for your machine.
The throttle shaft is a critical link in the engine speed control system of a ride-on concrete trowel. It connects the operator's throttle input to the engine's carburetor or throttle body, allowing the machine to ramp engine RPM up or down as finishing demands change. When the throttle shaft wears, bends, or develops play, the operator loses precise control over rotor speed, which can result in uneven surface texture or marks in freshly placed concrete. Replacing the shaft kit promptly keeps the trowel operating at the correct speed range for each stage of the finishing pass.
