Description

Overview:
This 5 x 5 x 12 mm square parallel key is a small but essential drive component for petrol lawn mowers. Made from steel for strength and wear resistance, it locates in the keyway on a shaft and matching hub to lock parts together and transmit torque without slip. It is used on Stihl/Viking machines, including MB 655.3 RS and RM 655.1 RS, where precise sizing is important to protect the shaft and hub from damage. Suitable for routine servicing and repairs, the key helps ensure smooth, reliable operation of blade drive, pulleys, or gear components in demanding garden and grounds maintenance work.

Key Features:
- Precision 5 mm x 5 mm x 12 mm sizing for a correct keyway fit
- Steel construction for dependable strength and long service life
- Maintains positive drive to prevent slippage between shaft and hub
- Helps reduce wear to keyways by matching the intended fit and profile
- Straightforward to fit and replace during standard maintenance
- Suitable for high‐vibration use typical of petrol lawn mowers
- Compatible with selected Stihl/Viking walk‐behind mower models
- Compact spare to keep on hand for quick repairs and minimised downtime

Typical Applications:
Used to secure pulleys, blade clutches, gears or drive hubs to a mower crankshaft or transmission shaft. Common during blade service, belt or pulley changes, or when restoring drive after a sheared or missing key. Suitable for domestic and professional lawn care, including gardeners, landscapers, grounds teams, and hire fleets.
