The Wacker Neuson is a genuine OEM Key 3 X 1/4 designed for CRT36 and CRT46 series ride-on concrete power trowels. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original component installed at the factory. Confirmed fitment covers the CRT36ASO, CRT36ASN, CRT46ASO, CRT46KHN, and CRT46KHO models. When you need a dependable, correctly sized key to restore your trowel's drivetrain integrity, part number is the correct replacement.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to the exact 3 x 1/4 profile required for proper shaft-to-hub engagement, ensuring no slop or misalignment in the connection.
- Drop-In Installation — Matches the original keyway geometry on CRT36 and CRT46 trowels, sliding directly into the existing slot without modification.
- Broad CRT Series Coverage — Fits CRT36ASO, CRT36ASN, CRT46ASO, CRT46KHN, and CRT46KHO ride-on concrete trowels in a single part number.
- Torque Transmission Restored — A correctly fitted key locks the shaft and hub together, allowing full torque transfer to the trowel rotor; a worn or missing key causes slippage, uneven blade rotation, and poor surface finish.
- Verified Wacker Neuson OEM Part — Part number 5000087962 is confirmed in Wacker Neuson's official parts documentation for the listed CRT models, so you can order with confidence.
A key is a small precision component that sits in a machined slot — called a keyway — between a rotating shaft and the hub or gear it must drive. Its job is to lock the two parts together rotationally so that torque passes cleanly from one to the other without slipping. On a ride-on concrete trowel like the CRT36 or CRT46, this type of key is critical to maintaining consistent blade speed and smooth surface finishing. When a key shears, deforms, or wears oversize, the shaft and hub begin to rotate independently, causing vibration, erratic blade performance, and accelerated damage to the surrounding components — making prompt replacement essential to keep the trowel finishing accurately.
