Simplicity 1720387SM Left-hand Pulley

Product Description

The SIMPLICITY 1720387SM is a left-hand pulley designed for use in outdoor power equipment drivetrain systems. Pulleys of this type transfer rotational force from the engine or motor to belts that drive blades, augers, or ground-drive systems. This component is a direct mechanical link in the power transmission circuit and is typically replaced during belt and drive system maintenance. Installation is performed by technicians and experienced equipment service professionals familiar with small engine and power equipment repair.

This left-hand pulley is suited for residential and light commercial outdoor power equipment applications where drivetrain components require periodic replacement due to wear, belt slippage, or mechanical damage. Consult your equipment service manual to confirm the correct pulley orientation and belt routing before installation.

Installation Notes

Pulley replacement should be performed by a qualified small engine or power equipment technician. Disconnect the spark plug wire and relieve any belt tension before removing the existing pulley. Ensure the replacement pulley is seated fully on the shaft and that all fasteners are secured before reinstalling belt guards or covers.
