The Multiquip 25694-001 is a genuine OEM 4-Speed Bladeshaft Gearbox Assembly designed for SP4 flat saws and SP6457 pavement saws. As a factory-sourced component, it delivers the correct gear ratios, shaft dimensions, and internal tolerancing specified for these machines. Verified fitment covers SP4 and SP6457 series equipment, making it a direct drop-in for scheduled rebuilds or field replacements. DHS Equipment supplies this assembly straight from the Multiquip OEM supply chain, so you receive the exact part your saw was built around.
Key Features
- Genuine OEM Gearbox Integrity — Manufactured to Multiquip's exact internal gear and shaft specifications, ensuring correct power transfer from the engine to the blade at all four speed settings.
- Four-Speed Blade Speed Selection — The multi-speed gearbox allows operators to match blade surface speed to the cutting material, protecting the blade and delivering cleaner cuts in concrete and asphalt.
- Direct-Fit Replacement — Engineered to bolt into the existing bladeshaft position on SP4 and SP6457 models with the same mounting interface as the original assembly.
- Confirmed Fitment — Compatible with SP4 flat saws and SP6457 pavement saws; always cross-reference part number 25694-001 against your machine's serial plate before ordering.
- Sustained Cutting Output — A correctly functioning gearbox maintains consistent blade RPM under load; a worn or damaged unit causes blade speed fluctuation, excessive vibration, and accelerated blade wear.
The bladeshaft gearbox assembly is the core power-transmission component between a flat or pavement saw's engine and its cutting blade. It steps down engine speed through a series of internal gears and delivers rotational force to the bladeshaft at the correct RPM for the selected cutting speed. When the gearbox wears or fails, operators will notice increased vibration, inconsistent blade speed, difficulty engaging speed ranges, or complete loss of blade drive — any of which can compromise cut quality and operator control. Replacing this assembly with the correct OEM unit restores full, predictable cutting performance.
