Wacker Neuson 5000153708 Gearbox Assembly Kit Right Hand CRT

The Wacker Neuson 5000153708 is a genuine OEM Gearbox Kit designed for the CRT48 and CRT36 series ride-on concrete trowels. As a direct factory replacement, this kit restores the gearbox to original operating condition and is confirmed to fit the CRT48-25K-L, CRT48-25K-H, CRT36-23K-H, CRT36-24A-H, CRT36-24A-E, and CRT36-25K-H models. Sourced directly from Wacker Neuson, part number 5000153708 meets the same specifications as the component installed at the factory. When gearbox wear or failure threatens your finishing schedule, this kit delivers a complete, like-for-like solution to get your trowel back to work.

Key Features

• Complete Kit Configuration — Includes all components required for a full gearbox service in a single part number, so nothing is left out when you open the machine.
• Genuine OEM Specification — Manufactured to Wacker Neuson's exact gear-ratio and torque-transfer tolerances, ensuring the trowel's rotor arms maintain the correct blade speed and finishing pattern.
• Broad CRT Series Fitment — Verified for the CRT48-25K-L, CRT48-25K-H, CRT36-23K-H, CRT36-24A-H, CRT36-24A-E, and CRT36-25K-H ride-on trowels — covering both 48-inch and 36-inch platform sizes.
• Restored Finishing Performance — A worn or failed gearbox causes uneven rotor speed, inconsistent blade pitch control, and rough surface finish; this kit brings output back to spec.
• Drive-Train Integrity — Gearbox failure under load can result in sudden loss of rotor control on a ride-on trowel; replacing at the first sign of wear protects the operator and the slab surface.

The gearbox on a ride-on concrete trowel transfers power from the engine to the rotor assembly, converting engine output into the controlled, high-torque rotation that drives the finishing blades across the slab. It also plays a key role in regulating blade pitch through the spider assembly, which directly affects finish quality and surface flatness. When the gearbox wears — through oil starvation, seal failure, or prolonged high-cycle use — operators will notice vibration, loss of rotor speed consistency, unusual noise, or reduced blade pitch response. Left unaddressed, gearbox deterioration accelerates damage to surrounding drivetrain components and compromises the finished surface.
