Murray 1719879sm Drive Disc with Spindle

Product Description

The MURRAY 1719879sm is a drive disc with spindle assembly used in friction-drive lawn and garden equipment. The drive disc engages the traction system, transferring power from the engine to the drivetrain to control ground speed and direction. This component is a direct replacement part for Murray-branded outdoor power equipment and is typically serviced by small-engine technicians or experienced equipment mechanics when wear or damage causes loss of traction or erratic drive behavior.

This part fits Murray lawn and garden equipment that uses a friction-drive traction system. Friction-drive assemblies are common in walk-behind mowers and similar self-propelled equipment. The drive disc contacts the drive plate or cup to transmit motion, and wear over time is a normal service interval replacement. Replacement is recommended when the disc surface is glazed, worn flat, or cracked.

Key Features

• Drive disc and spindle supplied as an assembled unit for straightforward replacement
• Designed to restore proper traction and ground drive performance in friction-drive systems
• OEM Murray part number ensures correct fitment and dimensional accuracy
• Spindle included eliminates the need to source components separately

Compatibility

Designed as an OEM-style replacement drive disc with spindle for Murray friction-drive lawn and garden equipment.

Installation Notes

Installation is typically performed by small-engine technicians or qualified equipment service personnel. Disconnect the spark plug wire before beginning any drivetrain disassembly to prevent accidental engine start. Inspect the mating drive plate or cup for wear before installing the new disc, as a worn mating surface will accelerate disc wear. Refer to the equipment service manual for proper component alignment and fastener procedures.
