Multiquip 28828-351 Shift Arm Cutter Assembly - OEM Replacement Part for Pavement Saws

The shift arm cutter assembly controls the transmission engagement system on Multiquip walk-behind pavement saws, translating operator input from the transmission engage/disengage lever to the spline gear assembly that drives the rear wheels. This critical drivetrain component allows operators to toggle between powered propulsion for cutting operations and manual push mode for repositioning the saw on the job site. When the transmission lever is lifted to the engaged position, the shift arm cutter ensures proper spline-to-rear-wheel contact, delivering sufficient pressure to prevent wheel slippage during cutting operations. A worn or damaged shift arm can result in incomplete transmission engagement, rear wheel slippage, or inability to disengage for manual pushing around the work site.

This assembly is engineered to work seamlessly with the SP2S20H's transmission system, which operates at 3,600 engine RPM with a blade shaft speed of 2,270 RPM. Proper function of this component is essential for maintaining the precise control needed when tracking cuts using the front pointer alignment system.
