The Multiquip EM20726 Key is a genuine OEM replacement designed for Whiteman ride-on and walk-behind power trowels, including the STX55J6, STX55Y6, STXD6i, and B46S90. Sourced directly from Multiquip, this key ensures an exact fit with no guesswork when it comes to compatibility. It is a direct drop-in replacement that restores proper mechanical drive engagement on confirmed fitment models. If you are running any of these trowel models, the EM20726 is the correct Multiquip-specified part for this application.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's exact dimensional tolerances, ensuring the key seats flush within the keyway without play or slop that could cause premature wear.
- Direct Drop-In Replacement — Installs directly into the existing keyway slot with no machining or modification to the shaft or hub required.
- Confirmed Trowel Fitment — Verified for the STX55J6, STX55Y6, and STXD6i hydrostatic ride-on trowels, as well as the B46S90 walk-behind trowel.
- Restores Positive Drive Engagement — A worn or sheared key allows the shaft to spin independently of the hub, causing loss of blade or drive power; replacing it immediately restores full mechanical lock between components.
- Safety-Critical Component — A failed key on a power trowel can result in sudden loss of blade control; using the correct OEM-specified replacement is essential for safe machine operation.
A key is a small but critical mechanical fastener that locks a rotating shaft to a hub, gear, or sprocket, preventing the two components from slipping relative to each other during operation. On power trowels, this part transmits torque from the drive system to the blade or drive assembly, meaning the machine cannot function correctly without it properly seated. When a key shears or wears down, the driven component spins freely on the shaft, resulting in an immediate loss of power transmission that will halt productive work until the key is replaced.
