The Multiquip 21185 Spacer 1/2 x 5/16 x 3/8 P33-3 is a genuine OEM component designed for FCG1-6HA, FCG1, and SFCG1 concrete saws. As a direct OEM replacement sourced through Multiquip's authorized parts program, the part delivers an exact dimensional match to the original part it replaces. Correct spacing is critical to proper shaft and component alignment in these concrete saw models, and this spacer ensures everything seats the way it was engineered to. If you're servicing an FCG1-series saw, the part is the correct specification part for the job.
Key Features
- Exact OEM Dimensions — Manufactured to the original 1/2 x 5/16 x 3/8 specification, ensuring correct clearance and positioning between mating components without guesswork.
- Direct Drop-In Fit — Engineered to seat exactly as the original, requiring no machining or shimming during reinstallation on FCG1-series concrete saws.
- Broad FCG1 Series Coverage — Compatible with FCG1-6HA, FCG1, and SFCG1 concrete saw models, covering the full range of Multiquip flat-cut green saw variants.
- Preserves Shaft Alignment — A correctly installed spacer maintains proper component spacing along the drivetrain, preventing premature wear on adjacent bearings and rotating assemblies.
- Genuine Multiquip OEM Part — Supplied as an authorized OEM component, built to the same material and tolerance standards as the part originally installed at the factory.
A spacer is a precision-dimensioned collar or ring used to maintain a set distance between two components on a shaft or within an assembly. In a concrete saw like the FCG1 series, spacers keep rotating and stationary parts correctly positioned relative to one another, preventing contact, misalignment, and uneven load distribution. When a spacer is worn, deformed, or missing, adjacent components can shift out of position, leading to accelerated wear on bearings, blades, or drive components and potentially affecting the accuracy of the cut.
