LG Washing Machine Bolt,Common

The LG Washing Machine Common Bolt (Part Number: FAA30850701) is an authentic original equipment manufacturer (OEM) replacement mechanical fastener designed for LG Direct Drive front-load and top-load washing machines as well as washer-dryer combination units. Threaded directly into the center of the main stainless steel tub drive shaft, this high-strength bolt clamps the outer magnetic motor rotor securely against the splined drive shaft. It withstands intense alternating rotational torque, rapid acceleration, and high-RPM spin vibrations without loosening or shearing.

Key Features

• High-Tensile Hardened Steel Construction: Manufactured from heavy-duty forged steel engineered to endure extreme shear stresses and torsional loads during high-speed spin extraction.

• Integrated Flanged Washer Collar: Features an oversized, captive stepped washer flange that distributes clamping pressure evenly across the rotor hub to prevent cracking and localized metal fatigue.

• Corrosion-Resistant Zinc Coating: Plated with a protective anti-rust finish designed to withstand high-humidity laundry environments and minor detergent exposure.

• Hex Head Drive Profile: Precision-machined hex head allows for high-torque fastening and secure socket wrench engagement during installation and removal.

Benefits

• Solves loose motor rotor hubs, grinding/clunking noises during spin or agitation, drive shaft play, motor error codes (such as "LE" motor lock faults), or stripped/damaged center bolts.

• Ensures 100% torque transmission from the Direct Drive motor to the inner wash basket.

• Direct OEM replacement guarantees factory-matched thread pitch, shaft diameter, and clamping force.

Applications

Designed specifically for select LG Direct Drive washing machines, Inverter front-loaders, top-loaders, and washer-dryer combination units requiring part number FAA30850701.

What's Included

• 1 x Genuine LG Direct Drive Washer Center Rotor Flange Bolt (FAA30850701)

Usage Instructions

1. Unplug the washing machine from the main AC electrical outlet and turn off water supply valves before servicing.

2. Remove the rear cabinet service cover to access the Direct Drive motor assembly.

3. Hold the outer motor rotor firmly (or use a locking tool) and use a socket wrench to unscrew the existing center rotor bolt.

4. Inspect the drive shaft splines and rotor hub for wear or damage.

5. Thread the new LG FAA30850701 center bolt through the rotor hub into the drive shaft (apply medium-strength threadlocker if recommended by the manufacturer service manual).

6. Torque the bolt securely to factory specification, reattach the rear cabinet cover, and run a test cycle.

Safety Instructions

• Electrical Hazard: Always disconnect main AC power before removing protective rear cabinet panels or servicing internal motor components.

Care Instructions

• Ensure threads are clean and free of debris or old thread compound before torquing the bolt to avoid cross-threading.
