The Multiquip 20401 Input Shim 0.020 Thick is a genuine OEM component designed for a wide range of Multiquip and Whiteman walk-behind power trowels, including SCT36, SCT46, BA-Series, CA-Series, and JA-Series models. As a factory-sourced part, the part is manufactured to the exact dimensional tolerances required for proper drivetrain alignment and spacing. Sourcing the correct shim thickness is critical — using an incorrect specification can introduce play or binding in the input assembly, leading to accelerated wear across connected components. DHS Equipment supplies this part direct, so you can be confident you are receiving the correct 0.020-inch shim for your machine.
Key Features
- Exact Thickness Specification: — Precision-ground to 0.020 inches, ensuring correct input shaft spacing and eliminating unwanted axial play in the drivetrain assembly.
- Genuine OEM Sourcing: — Manufactured by Multiquip to the same dimensional standards as the original component, so fitment and function match the factory build exactly.
- Broad Trowel Compatibility: — Fits SCT36, SCT46, BA-Series, CA-Series (including CA4HC, CA4HM, CA4.4HM), JA-Series, and HPHA/HPLA-Series walk-behind power trowels.
- Drivetrain Alignment Integrity: — Correct shimming keeps input components properly loaded, protecting gears, bearings, and shafts from misalignment-induced wear.
- Drop-In Replacement: — Dimensionally identical to the original, fitting into the existing input assembly without additional machining or adjustment beyond standard service procedure.
An input shim is a precision spacer used within the drivetrain or gearbox assembly of a walk-behind trowel to set the correct axial position and preload of the input shaft and its associated components. By controlling the gap between rotating and stationary parts, the shim ensures gears and bearings operate within their designed load range. When a shim is worn, deformed, or the wrong thickness, it can allow excess shaft movement that accelerates bearing wear, causes gear noise, and ultimately leads to more significant drivetrain damage if left unaddressed.
