Description
Overview:
This is a genuine Stihl Woodruff Key, size 4 x 6.5 mm (approx. 0.16 x 0.26 in), part number 9482 435 0820. Made from hardened steel with a half‐moon profile, it is used to lock a hub securely to a shaft, preventing slippage between rotating parts. It is suitable for Stihl sweepers and mowers, including the BM 500 sweeper and GB 350, where precise drive alignment is essential. The key sits in the shaft keyway and engages the mating hub, helping maintain smooth, safe operation under vibration and load. Using the correct OEM key protects shafts and hubs from wear and helps restore proper function after routine maintenance or component replacement.
Key Features:
- Genuine Stihl OEM part for reliable fit and performance
- Size 4 x 6.5 mm (approx. 0.16 x 0.26 in) for the specified keyway and hub interface
- Hardened steel construction for strength and long service life
- Precision machined to seat flush and transmit torque without slippage
- Helps maintain drive alignment and timing in rotating assemblies
- Suitable for high‐vibration use in sweepers and walk‐behind mowers
- Straightforward to fit and remove during routine servicing
- Supports safe operation by reducing the risk of hub or shaft damage
Typical Applications:
Used to secure pulleys, brush rollers, blade hubs, impellers, and transmission components on compatible Stihl machines. Typical use includes restoring the drive connection after replacing a pulley or hub, or when a worn or sheared key has caused misalignment or slipping. Always match the 4 x 6.5 mm size to your original key and keyway before fitting.
Also known as:
Half‐moon key, shaft key, keyway key, drive key, machine key. These terms describe the same style of semi‐circular key used to couple a rotating hub to a keyed shaft.
