Husqvarna 532145102 Transmission Sheave Lawn Mower

Product Description

The HUSQVARNA 532145102 is a genuine OEM transmission sheave designed for use in Husqvarna walk-behind and riding lawn mowers. A transmission sheave is a grooved pulley component that transfers belt-driven power from the engine to the transmission or drive system, enabling ground propulsion. This part is manufactured to original equipment specifications, ensuring proper belt alignment, consistent engagement, and reliable power transfer throughout the drive train. It is a direct replacement for worn, cracked, or damaged sheaves and is typically installed by qualified outdoor power equipment technicians or experienced service professionals.

This sheave is suited for residential lawn mower applications where the drive belt and transmission system require a matching OEM-spec pulley to maintain proper drive engagement. Correct sheave sizing and profile are critical to belt tracking and overall drivetrain performance. When the original sheave shows signs of wear, glazing, or physical damage, replacing it with a genuine OEM part restores factory drive performance. Refer to the mower model's service manual to confirm this part number applies to the specific unit being serviced.
