Key Features
- Precision Thickness Tolerance — Manufactured to an exact 0.003-inch specification, ensuring correct input shaft clearance and preventing drivetrain misalignment in walk-behind trowel assemblies.
- Genuine OEM Component — Sourced directly from Multiquip, this shim matches the original part installed during production — no guesswork on material grade or dimensional accuracy.
- Broad Walk-Behind Trowel Compatibility — Confirmed fitment across CA4HC, HPHA36C5H, HPHA46411H, HPLA46411H, BA-SERIES, JA-SERIES, CA-4-4H, CA4HM, CA4.4HM, HPHA-46-SERIES, and HPLA-HPHA-36 models.
- Drop-In Replacement — Installs in the same position as the original shim with no machining or adjustment to surrounding components required.
- Protects Drivetrain Components — A correctly shimmed input assembly reduces wear on adjacent bearings and gears, extending the service life of the trowel's power transmission system.
An input shim is a thin, precisely machined spacer used to set the correct axial clearance between rotating components in a trowel's input shaft assembly. It ensures that gears, bearings, and shafts are properly aligned and loaded during operation, preventing excessive play or binding that can accelerate wear on surrounding drivetrain parts. When a shim is worn, damaged, or incorrectly sized, it can cause increased vibration, noise, and premature failure of the input shaft components — making correct shim selection critical during any drivetrain service or rebuild.
