Husqvarna 598995101 Worm Gear

The Husqvarna 598995101 Worm Gear is a genuine OEM component designed for the CRT48PS, CRT36, and CRT48 power trowels. Sourced directly from Husqvarna, this worm gear meets the exact design and material specifications of the original part, ensuring correct engagement and load transfer within the trowel's gearbox. DHS Equipment supplies this part to help keep your equipment running at full capacity. Cross-reference part number 598995101 against your parts diagram before ordering to confirm fitment for your specific machine.

Key Features

• OEM-Grade Gear Material — Manufactured to Husqvarna's original hardness and tooth-profile specifications, ensuring proper mesh and load capacity within the trowel drivetrain.
• Drop-In Drivetrain Replacement — Engineered to the original dimensions for direct installation into the gearbox housing without modification to mating components.
• Fits CRT Series Power Trowels — Compatible with CRT48PS, CRT36, and CRT48 ride-on power trowels — confirm part number 598995101 against your machine's parts diagram.
• Restored Blade Speed Control — A correctly functioning worm gear maintains accurate pitch adjustment and consistent blade rotation; a worn gear causes slippage, uneven finishing, and loss of pitch response.
• Genuine Husqvarna OEM Part — Carries full Husqvarna OEM designation, meaning this component is built and validated to the same standard as the part that left the factory with your machine.

The worm gear is a core element of the power trowel's gearbox, converting the engine's rotational output into the controlled blade-pitch and rotation speed that produces a flat, finished concrete surface. It works in constant mesh with the worm wheel, transmitting torque while allowing precise speed reduction — making tooth geometry and material integrity critical to consistent trowel performance. When this gear wears or fails, operators typically experience erratic blade pitch response, unusual gearbox noise, or a complete loss of drive to the trowel arms, all of which compromise the quality of the concrete finish and bring work to a halt.
