Wacker Neuson 5002006155 Key A8 X 7 X 25

The Wacker Neuson Key A8 X 7 X 25 is a genuine OEM component designed for the CT30, CT36, and CT48 series walk-behind trowels, as well as select BPS and DPS series vibratory plates and floor saws. As a factory-sourced part, is manufactured to the exact dimensions and material standards required for correct seating and reliable torque transfer in the drivetrain. This key fits an extensive range of Wacker Neuson walk-behind trowel configurations — including gas, diesel, and electric variants in both standard and CE-compliant versions — making it a highly versatile stock item for rental fleets and service shops alike. Confirm your model number against the fitment list before ordering to ensure a direct match.

Key Features

• Exact OEM Dimensions: — Manufactured to the precise A8 x 7 x 25 profile required for correct keyway engagement, ensuring full torque transmission without slippage or play.
• Genuine Wacker Neuson Part: — Sourced directly from Wacker Neuson, this key meets the exact material hardness and dimensional tolerances specified for these drivetrain applications.
• Broad Fitment Across CT Series Trowels: — Compatible with CT30, CT36, and CT48 walk-behind trowels across gas (AGP, AGT), diesel (ADP, ADT), electric (EDT), and CE-compliant variants, plus select BPS/DPS vibratory plates and floor saws.
• Restores Positive Shaft-to-Hub Locking: — A worn or missing woodruff or parallel key allows shaft and hub components to rotate independently, causing rapid wear and loss of drive; replacing it restores the solid mechanical link between rotating parts.
• Drop-In Installation: — The standardized A-series key profile seats directly into the machined keyway slot with no fitting, grinding, or secondary machining required.

A drive key is a small but critical component that locks a rotating shaft to a hub, gear, or pulley, preventing the two parts from spinning independently of each other. In walk-behind trowels, this type of key transmits engine or motor torque through the drivetrain to the trowel arms, so a worn, sheared, or missing key will cause the drive to slip or fail entirely — stopping the machine mid-pour. Replacing a damaged key promptly with the correct OEM-spec part protects the surrounding shaft and bore from the accelerated wear that continued operation without a properly seated key would cause.
