The Multiquip 120226 Gearbox Mounting Block with Pin Assembly is a genuine OEM component designed for SP4 flat saws and SP605716, SP605720, SP605726, SP605730, SP605736, and SP6457 series pavement saws. As a direct OEM replacement, 120226 is manufactured to the same tolerances and material specifications as the original part, ensuring a straight swap with no guesswork. DHS Equipment stocks this part to keep your Street Pro series saw running at full cutting capacity.
Key Features
- Genuine OEM Construction — Machined to the same material and dimensional specifications as the original, maintaining the precise load-bearing characteristics a gearbox mount demands under saw vibration and torque.
- Integrated Pin Included — Supplied as a complete assembly with the locating pin, so the unit installs as a single unit rather than requiring separate hardware sourcing.
- Broad SP Series Compatibility — Confirmed fit for SP4 flat saws and SP605716, SP605720, SP605726, SP605730, SP605736, and SP6457 pavement saws — verify your model before ordering.
- Maintains Gearbox Alignment — A correctly seated mounting block keeps the gearbox positioned true to the blade shaft; a worn or cracked block allows gearbox shift under load, accelerating belt and bearing wear.
- Structural Integrity Under Continuous Load — Built to withstand the sustained vibration and cutting forces inherent to pavement and flat-saw operation, resisting flex and fatigue over extended service cycles.
The gearbox mounting block is the structural interface between the saw's gearbox and its main frame. It holds the gearbox in a fixed, aligned position so power transfers cleanly from the engine through the drive system to the blade. The integrated pin locks the block in register, preventing any rotational movement under load. When this block cracks, wears loose, or the pin shears, the gearbox shifts position during cutting — causing misalignment, uneven blade wear, excessive vibration, and potential gearbox damage that far exceeds the cost of the mounting block itself.
