The Multiquip 511661 Rear Axle is a genuine OEM component designed for the FS1 series floor saw. Sourced directly through Multiquip's authorized parts network, this rear axle is manufactured to the exact specifications required by your machine — ensuring a correct, direct installation with no guesswork. If you're running an FS1 concrete saw, this is the verified OEM replacement axle for that application.
Key Features
- OEM-Matched Construction: — Manufactured to the original dimensional and material tolerances required for the FS1 rear axle position, maintaining proper load transfer and alignment across the drivetrain.
- Direct-Fit Replacement: — Designed to install in the same mounting position as the original, with matching geometry so the axle seats correctly within the saw's rear assembly.
- FS1 Concrete Saw Compatibility: — Verified fitment for the Multiquip FS1 floor saw — confirm your model code before ordering to ensure accuracy.
- Drivetrain Integrity: — A worn or damaged rear axle can cause blade misalignment, uneven tracking, and loss of control during cutting passes. A correctly functioning axle keeps the saw running straight and stable under load.
- Genuine OEM Part: — Backed by Multiquip's OEM parts program, this component meets the same quality standard as the original part that shipped with your machine.
The rear axle on a floor saw carries the weight of the machine at the back end and plays a direct role in how the saw tracks along a cut line. It connects the rear wheels to the frame and transmits movement forces as the operator guides the machine. When the rear axle wears, bends, or fails, the saw can pull to one side, create inconsistent cut depths, or become difficult to maneuver — especially under the load of a large-diameter blade cutting into concrete or asphalt. Replacing a damaged axle promptly restores straight, controlled operation and protects surrounding drivetrain components from secondary wear.
