The Husqvarna 542198878 Hydraulic Motor is a genuine OEM component designed for Husqvarna FS-series floor saws, including the FS4800D, FS5000D, FS6600D, FS6800D, FS7000D, FS7000DL, FS7000DMT, FS8400D, and FS5000 floor saws. As a direct OEM replacement, this motor is built to the same specifications as the original unit, ensuring correct hydraulic flow characteristics and drive output for demanding flat-saw applications. Cross-reference part number 542198878 against your machine's parts diagram to confirm fitment before ordering. DHS Equipment supplies this part to help keep your floor saw running at full capacity.
Key Features
- OEM-Matched Hydraulic Specifications — Built to the same displacement and pressure ratings as the original unit, ensuring correct drive torque and blade speed for productive slab cutting.
- Direct Replacement Fit — Engineered to match the original port configuration and mounting interface, allowing straightforward installation without modification to hydraulic lines or mounting hardware.
- Broad FS-Series Compatibility — Fits a wide range of Husqvarna floor saws including the FS4800D, FS5000D, FS6600D, FS6800D, FS7000D, FS7000DL, FS7000DMT, FS8400D, and FS5000.
- Restored Blade Drive Performance — A worn or failing hydraulic motor causes loss of cutting power, inconsistent blade speed, and increased load on the hydraulic system; replacing it with this genuine OEM unit restores full drive performance.
- Genuine Husqvarna Quality — Sourced directly from Husqvarna's OEM supply chain, this motor meets the internal clearance tolerances and seal material grades required for sustained operation under the high hydraulic pressures generated by heavy-duty floor saws.
The hydraulic motor is the component responsible for converting hydraulic pressure from the machine's pump into the rotational force that drives the saw blade. In a floor saw, this motor must deliver consistent torque under continuous load as the blade cuts through concrete, asphalt, and reinforced slabs. When the hydraulic motor wears internally — through seal degradation, worn rotors, or contamination — the result is reduced blade speed, overheating of the hydraulic circuit, and uneven cutting performance. Replacing the motor with a genuine OEM unit like the 542198878 restores the precise flow and pressure balance the machine's hydraulic system was designed to operate within.
