The Wacker Neuson Rocker Arm Support is a genuine OEM component designed for CRT48 ride-on concrete trowels and the CT48-13A-V walk-behind trowel. Sourced directly from Wacker Neuson, this part carries the same specifications as the original, ensuring a direct fit across multiple CRT48-34V, CRT48-31V, and CT48 series machines. Whether you are servicing a standard ride-on, a high-speed configuration, or an electronic steering variant, part number is the verified replacement for these trowel families. Keeping this support in good condition is essential to maintaining consistent blade pitch control and smooth trowel operation on the finishing deck.
Key Features
- Genuine OEM Construction: — Manufactured to Wacker Neuson's original material and dimensional tolerances for the rocker arm assembly, ensuring correct load distribution and pivot geometry on the finishing head.
- Broad CRT48 and CT48 Compatibility: — Verified fit across CRT48-34V, CRT48-31V, CRT48-31V-H, CRT48-31V-E, CRT48-31V-ES, CRT48-31V-ES-E, and CT48-13A-V trowel models, covering standard, high-speed, and electronic steering configurations.
- Drop-In Replacement: — Mounts using the existing hardware and pivot points on the trowel deck, allowing a straightforward swap during scheduled maintenance or unplanned repairs.
- Blade Pitch Integrity: — A correctly functioning rocker arm support maintains consistent blade angle across all finishing arms, preventing uneven surface texture and loss of finishing control on fresh concrete slabs.
- Verified Part Number: — Cross-reference 5000158172 against your machine's serial number and model designation before ordering to confirm an exact match for your specific trowel configuration.
The rocker arm support is a structural pivot component within the trowel's pitch-control mechanism. It bears the load transferred from the spider assembly to the finishing blades, allowing the operator to adjust blade angle uniformly across the rotating finishing head. When this support wears, cracks, or becomes damaged, blade pitch becomes inconsistent across individual arms, resulting in uneven finishing passes, surface chatter, and loss of operator control — issues that are particularly critical when working to tight flatness tolerances on commercial concrete pours.
