The Wacker Neuson Control Arm Insert is a genuine OEM component designed for the CRT36 and CRT46 series ride-on concrete trowels, including the CRT46KHN, CRT46KHO, CRT46ASO, CRT36ASO, and CRT36ASN models. Sourced directly from Wacker Neuson, this insert matches the original part in material, geometry, and fit — so there's no guesswork when you're pulling a machine apart on the slab. Confirmed fitment across both the 46-inch and 36-inch ride-on trowel configurations gives you confidence you're ordering the right part the first time.
Key Features
- Genuine OEM Construction: — Manufactured to Wacker Neuson's original material and dimensional standards, ensuring the insert seats and functions exactly as the design intends within the control arm assembly.
- Drop-In Replacement: — Matches the original mounting interface of the control arm on CRT36 and CRT46 ride-on trowels, allowing straightforward installation without rework or improvisation.
- Broad CRT Series Coverage: — Fits the CRT46KHN, CRT46KHO, CRT46ASO, CRT36ASO, and CRT36ASN ride-on concrete trowel models, covering both overlapping and non-overlapping rotor configurations.
- Maintains Steering and Pitch Control: — A worn or damaged control arm insert compromises the operator's ability to steer and adjust rotor pitch accurately, leading to uneven finish quality across the slab surface.
- Verified OEM Part Number: — Part number 5000087991 is the current Wacker Neuson OEM reference for this insert, so cross-referencing against your machine's serial number is straightforward.
The control arm insert is a critical wear interface within the steering and pitch-control linkage of a ride-on concrete trowel. It cushions and guides the control arm's movement, allowing the operator to apply smooth, consistent pressure to adjust rotor blade pitch and steer the machine across the slab. When this insert wears out or cracks, it introduces slop into the control linkage — making the machine harder to steer precisely and causing uneven trowel pressure that shows up as inconsistent surface finish. Replacing it promptly with a correctly specified insert restores the tight, responsive feel the machine was built to deliver.
