Murray 1674643sm Pulley Hub Assembly

Product Description

The MURRAY 1674643sm is a pulley hub assembly designed as a direct replacement component for Murray lawn and garden equipment. This assembly serves as the mechanical interface between the drive belt and the associated shaft or spindle, transmitting power through the drive system to maintain proper mowing or drive operation. It is installed by small engine mechanics and experienced outdoor power equipment technicians during routine drivetrain service or after component failure. Correct pulley hub fitment is essential for belt alignment and consistent power transfer in walk-behind and riding mower applications.

This part is suited for use in Murray-brand residential lawn and garden equipment where the original pulley hub assembly has worn, cracked, or failed. It is a common service part for drivetrain and deck belt systems. Technicians typically encounter this component during seasonal maintenance, belt replacement, or following a belt-jumping or slipping complaint. It is applicable to Murray riding mowers and related outdoor power equipment that use this hub assembly configuration in the drive or cutting deck system.
