Key Features
- Exact OEM Thickness Tolerance — At 0.005 inches thick, this shim is manufactured to the precise dimensional spec required for correct output shaft end-play adjustment in Multiquip trowel gearboxes.
- Genuine Multiquip OEM Part — Sourced directly from Multiquip, part 20404 carries the same quality and material grade as the original component installed at the factory.
- Broad Walk-Behind Trowel Compatibility — Fits CA-4-4H, CA4HC, CA4HM, CA4.4HM, JA-SERIES, BA-SERIES, HPLA46411H, HPHA46411H, HPHA36C5H, HPLA-HPHA-36, HPHA-46-SERIES, SCT36, and SCT46 models.
- Critical for Gearbox Rebuild Accuracy — Proper shimming eliminates excessive output shaft play, preventing premature gear and bearing wear that leads to costly gearbox damage.
- Direct Service Part — Used during output shaft servicing and gearbox reassembly, this shim drops into the existing assembly without machining or modification of surrounding components.
An output shim is a precision-thickness spacer used during gearbox assembly to set the correct end-play and pre-load on the output shaft. In a walk-behind power trowel, the output shaft transfers rotational force from the gearbox to the trowel arms and blades — so correct shaft positioning is essential for smooth, consistent blade rotation. When a shim is missing, worn, or the wrong thickness, the output shaft can develop excessive play, causing vibration, uneven trowel blade engagement, accelerated bearing wear, and eventual gearbox failure.
