Multiquip 38214 Pinion/Bushing Assembly - OEM Replacement Part for Concrete Saws

The pinion/bushing assembly is a critical drive component that transfers power from the motor to the blade arbor on walk-behind concrete saws. This precision-machined assembly ensures proper blade rotation and maintains the 2836 RPM maximum spindle speed required for optimal cutting performance.

Designed specifically for the SP118 concrete saw, this OEM assembly integrates the pinion gear and bushing into a single replacement unit, simplifying maintenance and ensuring proper alignment of drive components. The SP118 is engineered to handle blades up to 18 inches in diameter with a 1.0-inch arbor, cutting to a maximum depth of 7.0 inches. Worn pinion assemblies can cause irregular blade speed, excessive vibration, poor cut quality, or complete drive failure—replacing this component at the first signs of wear prevents costly downtime and maintains the saw's 274-pound operating mass balance.
