Multiquip 9119 Pulley 2AK54X7/8 5.25 OD HD48 - OEM Replacement Part

This pulley transfers power from the engine to the gearbox on Multiquip HDA Series walk-behind trowels, maintaining the critical drive system that rotates the 48-inch rotor at speeds from 35 to 225 rpm. The 2AK54 configuration with 7/8-inch bore and 5.25-inch outer diameter is engineered to work with the dual V-belt system that drives the helical worm gear gearbox beneath the engine.

During regular inspection intervals, examine this pulley for signs of glazing, cracks, sidewall wear, or groove damage that can cause belt slippage or premature V-belt failure. A worn or damaged pulley will show symptoms including belt squealing, reduced rotor speed, uneven blade rotation, or visible V-belt wear patterns. The pulley works in conjunction with the gearbox input shaft to deliver consistent power transfer for professional concrete finishing operations on machines handling up to 327 lb operating weight.

Compatible with the following Multiquip trowel models:

• HDA Series Walk-Behind Trowels
