The Multiquip 20398 Input Shim 0.003 Thick is a genuine OEM component designed for CA-4-4H series walk-behind power trowels. As a Multiquip OEM part, 20398 is manufactured to the exact dimensional tolerances required to maintain proper drivetrain alignment and load distribution within the trowel's input assembly. This shim is confirmed for use on CA-4-4H equipment, making it a dependable choice when restoring correct clearances during service or rebuild work.
Key Features
- Precision Thickness Control — Manufactured at exactly 0.003 inches thick, ensuring correct input shaft spacing and eliminating the guesswork that leads to premature wear or misalignment.
- Genuine OEM Construction — Produced to Multiquip's original material and dimensional specifications, so the shim maintains its profile under the compressive loads typical of trowel input assemblies.
- Direct-Fit for CA-4-4H Trowels — Engineered specifically for the CA-4-4H walk-behind power trowel series, fitting directly into the input assembly without modification.
- Supports Drivetrain Integrity — Correct shimming keeps input components seated and loaded evenly; a worn or missing shim allows unwanted play that accelerates gear and bearing wear throughout the drivetrain.
- Verified Part Number — Order with confidence using Multiquip part number 20398, cross-referenced directly to CA-4-4H service documentation for accurate fitment.
An input shim is a thin, precisely dimensioned spacer installed within the input shaft or gear assembly of a walk-behind trowel. Its purpose is to set and maintain the correct axial clearance between rotating components, ensuring that gears, bearings, and shafts are loaded and aligned as intended. When a shim is worn, damaged, or missing, excessive end-play or side-load develops in the input assembly, which can cause accelerated bearing failure, abnormal gear noise, and eventual breakdown of the drivetrain — leading to costly repairs that a simple shim replacement could have prevented.
