Multiquip 20726-001 Key

The Multiquip 20726-001 Key is a genuine OEM replacement designed for B46S90 walk-behind power trowels and STX55J6, STX55Y6, and STXD6i ride-on power trowels. As a factory-sourced component, it delivers an exact match to the original specification — ensuring correct fit and reliable engagement in service. Sourced directly through an authorized Multiquip dealer, the 20726-001 is the same part installed at the factory, so there is no guesswork on compatibility. If your current key is worn, sheared, or missing, this is the direct replacement to get your trowel back in operation.

Key Features

• Genuine OEM Construction — Manufactured to the same material hardness and dimensional tolerancing as the original, ensuring the key seats and transfers torque correctly without slipping or accelerated wear on the keyway.
• Drop-In Installation — Profiles match the original keyway geometry on compatible shafts, seating cleanly without filing, shimming, or modification.
• Broad Trowel Compatibility — Confirmed fitment across B46S90 walk-behind and STX55J6, STX55Y6, and STXD6i ride-on power trowel models.
• Torque Transfer Integrity — A correctly fitted key locks rotating components — such as drive pulleys or blade hubs — to the shaft, maintaining the power transfer needed for consistent blade speed and finishing performance.
• Prevents Secondary Damage — Replacing a worn or sheared key promptly protects the shaft and mating component keyways from damage that would result in far costlier repairs.

A key is a small, precisely dimensioned metal component that fits into matching slots — called keyways — machined into a shaft and a hub or pulley. Its role is to lock the two components together rotationally so that drive power is transmitted from the shaft to the connected component without slipping. When a key shears or wears, the hub or pulley can spin independently of the shaft, causing a complete loss of drive to that component. Left unaddressed, a failed key allows the shaft and hub keyways to batter each other, turning a minor replacement into a major repair.
