Murray 20697ma Woodruff Key 9

Product Description

The MURRAY 20697ma is a Woodruff Key 9 replacement part designed for use in lawn and garden power equipment. A Woodruff key is a small, semi-circular metal key that fits into a mating keyway on a shaft and hub assembly to lock rotating components in alignment and prevent slippage. This type of fastener component is a common service part in small-engine applications, typically replaced after a blade strike or shaft impact event causes the key to shear. Technicians servicing Murray lawn and garden equipment keep these on hand as a standard consumable repair part.

This Woodruff Key 9 is used in Murray-branded lawn and garden equipment where the OEM key specification calls for this size. Typical applications include crankshaft-to-flywheel assemblies in small gasoline engines, where the key positions the flywheel at the correct timing advance angle. It is installed during engine reassembly after a blade-strike inspection or flywheel removal procedure.

Key Features

• Semi-circular Woodruff key profile for positive rotational alignment in keyway assemblies
• OEM-specified size 9 profile for direct fitment in compatible Murray equipment
• Designed to shear under shock load to protect crankshaft and flywheel from damage
• Standard consumable service part for blade-strike and engine inspection repairs

Compatibility

Designed as an OEM-style replacement Woodruff key for Murray lawn and garden power equipment requiring a size 9 Woodruff key specification.

Installation Notes

Installation is performed by qualified small-engine technicians or experienced power-equipment service professionals. Always disconnect the spark plug wire and allow the engine to cool completely before accessing the flywheel or crankshaft assembly. Use a flywheel puller tool to remove the flywheel without damaging the crankshaft taper — never strike the flywheel directly. Ensure the keyway slots on both the crankshaft and flywheel hub are clean and free of debris before seating the new key.
