Multiquip 28322-003 Jackshaft Pulley 2F3V26X1 - OEM Replacement Part

The jackshaft pulley is a critical power transmission component that transfers rotational force from the engine to the bladeshaft assembly in Multiquip masonry saws. This 2F3V26X1 specification pulley mounts directly to the jackshaft and works in conjunction with V-belts to deliver consistent cutting power to the blade.

When troubleshooting blade performance issues such as slowing or stopping during cuts, technicians should inspect the jackshaft pulley along with V-belt tension. According to Multiquip maintenance procedures, proper belt tension requires 4-5 lbs of force with 1/8" deflection at the mid-point between pulleys. During belt adjustments, pulley alignment and belt parallelism must be verified using a straight edge from the jackshaft pulley to both the engine pulley and bladeshaft pulley. Misalignment or worn pulleys can cause diminished engine torque transfer, resulting in reduced cutting performance.

The jackshaft assembly on MP2-Series saws includes grease points that require daily lubrication with Premium Lithium 12 based grease conforming to NLG1 Grade #1 consistency. When replacing this pulley, technicians should loosen the four jackshaft mounting bolts and adjuster screw jam nuts to ensure proper installation and alignment.
