Key Features
- Precision-Machined OEM Housing — Machined to exact dimensional tolerances, ensuring the worm gear assembly seats and operates correctly within the gearbox.
- Direct-Fit Installation — Engineered to the original mounting interface, allowing straightforward installation on compatible Whiteman and International walk-behind trowel models.
- Broad Trowel Compatibility — Fits a wide range of models including CA4HC, CA5BC, J36-M30, B46, BS90C, BH90C, JS60C, JH90C, JH55C, BS46H11, BS46H90, JS36H90, JS36H55, B46S90, and CS24H55E.
- Protects Internal Gear Components — A correctly fitted gearworm case maintains proper gear mesh alignment, preventing premature wear on the worm gear and associated drivetrain components.
- Genuine Multiquip OEM Part — Sourced directly from Multiquip, part number 12874 meets the same specifications as the original component installed at the factory.
The gearworm case is the machined housing that encloses and supports the worm gear assembly within a walk-behind power trowel's gearbox. It holds the worm gear and associated components in precise alignment, allowing the engine's rotational power to be transferred smoothly to the trowel blades. When the case becomes cracked, worn, or damaged, gear mesh alignment is compromised, leading to accelerated wear on internal components, increased vibration, and eventual loss of blade drive. Replacing a damaged gearworm case with a correctly machined OEM unit restores the integrity of the gearbox and protects the surrounding drivetrain from further damage.
