The Wacker Neuson Machined Gearbox Housing is a genuine OEM component designed for CRT36 and CRT48 series ride-on concrete power trowels. This precision-machined housing is sourced directly from Wacker Neuson, ensuring exact dimensional conformance to the original specification. It fits an extensive range of CRT models including the CRT36-24A, CRT36-25, CRT36-26A, CRT48-31V, CRT48-33K, CRT48-34V, CRT48-35L, CRT48-35V, CRT48-37V, CRT48-57K, and associated variants including power steer, dual-fuel, electronic steering, and EU-spec configurations. When the gearbox housing is cracked, worn, or damaged, it compromises the integrity of the entire gearbox assembly — making prompt replacement with a correctly specified part essential to keeping the machine running true.
Key Features
- Precision-Machined OEM Housing — Manufactured to Wacker Neuson's exact bore tolerances and mounting geometry, ensuring the gearbox internals seat and align correctly without rework.
- Direct-Fit Replacement — Matches the original housing profile and bolt pattern, dropping into place on compatible CRT36 and CRT48 trowels using standard service procedures.
- Broad CRT Series Coverage — A single part number serves the CRT36-24A, CRT36-25, CRT36-26A, CRT48-31V, CRT48-33K, CRT48-34V, CRT48-35L, CRT48-35V, CRT48-37V, CRT48-57K, and associated power steer, dual-fuel, and EU variants.
- Structural Integrity for High-Load Operation — Ride-on trowel gearboxes operate under sustained rotational load; a correctly spec'd machined housing maintains the rigidity needed to prevent bearing misalignment and premature wear of internal components.
- Genuine OEM Part — Supplied by Wacker Neuson, this part carries the same part number used by authorized dealers and service centers, supporting accurate parts traceability.
The gearbox housing is the structural shell that encloses and supports the gearbox's rotating components — including gears, bearings, and shafts — that transfer engine or motor power to the trowel rotor arms. On a ride-on concrete trowel, the gearbox works under continuous rotational stress during finishing passes, and the housing must maintain precise internal geometry to keep all moving parts correctly aligned. A cracked or distorted housing allows lubricant to escape, introduces bearing play, and can lead to rapid wear or failure of the entire gearbox assembly, taking the machine out of service mid-pour.
