The MURRAY 1668066sm is an HA-profile V-belt with a 120.10-inch outer circumference, designed for use in Murray lawn and garden equipment. V-belts of this profile transmit drive power between pulleys on deck, blade, and drive systems found in residential and commercial outdoor power equipment. The HA profile indicates a standard fractional-horsepower belt cross-section suited to the pulley grooves specified for this application. Installation and replacement are typically performed by outdoor power equipment technicians or experienced service professionals.
This belt fits Murray lawn and garden applications where an HA-series drive belt is called out by the equipment service documentation. It is used in deck drive or transmission drive configurations on riding mowers and garden tractors that specify this belt profile and length. Refer to the original equipment service manual to confirm the correct routing path and tension adjustment before installation.
Designed as an OEM-style replacement V-belt for Murray lawn and garden equipment requiring an HA-profile belt with a 120.10-inch outer circumference. Consult the equipment service manual or OEM parts lookup to confirm fitment for your specific model.
Belt replacement on outdoor power equipment should be performed by a qualified technician. Disconnect the spark plug wire and engage the parking brake before beginning any belt service to prevent accidental engine start. Route the belt according to the diagram on the equipment deck or in the service manual, and verify proper tension and pulley alignment before returning the unit to service. Do not operate with a misrouted or improperly tensioned belt.
