Wacker Neuson 5003007018 Square Key 3/16 X 1-13/16

The Wacker Neuson Square Key 3/16 X 1-13/16 is a genuine OEM component designed for CT30, CT36, and CT48 series walk-behind trowels, including gas, diesel, electric, and variable speed variants. As a factory-sourced part, is manufactured to the exact dimensional tolerances required for correct shaft-to-hub engagement on these machines. This square key fits an extensive range of CT series trowel configurations — including AGP, ADP, AGT, ADT, AVP, AVT, BDT, and EDT models — as well as select VPG series vibratory plates. Confirm your model number against the fitment list before ordering to ensure a direct match.

Key Features

• Exact Dimensional Tolerance — Manufactured to OEM specifications, this square key delivers the precise 3/16 x 1-13/16 profile needed to maintain a secure, non-slip connection between mating shaft components.
• Genuine Wacker Neuson Part — Sourced directly through Wacker Neuson's OEM supply chain, part 5003007018 meets the same material and hardness standards as the key installed at the factory.
• Broad CT Series Compatibility — Fits CT30, CT36, and CT48 walk-behind trowels across gas, propane, diesel, electric, and variable speed configurations in both standard and CE-certified variants.
• Positive Power Transfer — A correctly fitted square key locks the drive components in rotational alignment, ensuring full torque is transferred without slip — a worn or missing key causes blade-speed loss and uneven finishing.
• Also Fits Select VPG Vibratory Plates — Confirmed fitment on VPG165V, VPG165A, and VPG170A vibratory plate compactors, making this a useful stock item across mixed Wacker Neuson fleets.

A square key is a small but load-critical drive component seated in matching keyways cut into a shaft and a mating hub or gear. It transmits rotational torque between the two parts, preventing relative movement that would otherwise cause wear, vibration, or complete loss of drive. When a square key shears, deforms, or works loose, power transfer is interrupted — resulting in erratic blade speed, unusual noise, or a trowel that fails to drive at all. Replacing a damaged key promptly with the correct OEM piece restores full drive integrity and prevents secondary damage to the keyway itself.
