- Direct Drop-In Replacement — Matches original part geometry for straightforward installation during gearbox service, shimming, or rebuild procedures.
- Broad Walk-Behind Trowel Coverage — Confirmed fitment across CA-SERIES, JA-SERIES, BA-SERIES, HPHA-SERIES, HPLA-SERIES, and SCT-SERIES equipment families.
- Drivetrain Alignment Support — Correct shimming maintains proper gear mesh and bearing load, preventing premature wear on input shaft components and extending gearbox service life.
- Genuine Multiquip OEM Part — Sourced directly from Multiquip, carrying the same part number (20400) used in factory assembly and authorized service documentation.
An input shim is a precision-thickness spacer used within a gearbox or drivetrain assembly to set the correct axial position of a shaft or gear. In walk-behind trowel applications, input shims control the preload and end-play of the input shaft, ensuring gears mesh at the correct depth and that bearing loads are properly distributed. When a shim is worn, damaged, or the wrong thickness, the result is excessive gear lash, abnormal noise, accelerated component wear, and potential gearbox failure — making correct shim selection critical during any drivetrain service or rebuild.
