Samsung Front-Load Washer Drive Shaft Flange Bolt (Part # DC60-40137A)

Secure the structural mechanical core of your laundry system with this Genuine OEM Samsung Front-Load Washer Drive Shaft Flange Bolt. This factory-certified, high-tensile structural fastener (Part # DC60-40137A, which replaces older factory codes like 2056511, AP4204689, and PS4205213) is designed to handle extreme torsional stress and high shear loads inside the washing machine’s main drivetrain.

This specific bolt anchors the spin basket directly to the rear drive system. On front-load washing machines, the stainless steel drum is mounted onto a three-pronged support bracket called a spider arm flange. The shaft of that spider assembly passes through the rear outer tub’s bearings, and this specialized bolt threads directly into the center core of the shaft to lock the large drive pulley wheel (or the direct-drive motor rotor magnet) firmly to the basket.

If this bolt stretches, shears off, or backs out of its tracking due to severe operational vibration, your washer will experience immediate mechanical failure. This causes severe symptoms, including a deafening banging, grinding, or roaring noise during spin cycles, a machine that spins but the inner metal drum remains loose and wobbly, or a washer that motor-hums perfectly while the drum fails to rotate at all.

Quick Info:

• Compatibility: Precision engineered for Samsung and Kenmore (402-Series) front-loading high-efficiency (HE) washing machines.

• Specialized Design Elements: Features a pre-applied blue anaerobic thread-locking compound (Loctite) chemically fused directly into the thread ridges. This compound activates under installation pressure, expanding to seal the threads and prevent the bolt from backing out during 1200 RPM spin cycles.

• Fixes Common Issues: Resolves severe drum wobbling, clunking noises during deceleration, a pulley or rotor slipping off the drive shaft, or a motor spinning independently of the wash basket.

• Difficulty: Advanced. While replacing the bolt itself requires only a socket wrench from the rear panel, accessing a sheared version or replacing the companion spider assembly requires a complete cabinet tear-down.

⚠️ Critical Installation & Torque Warning:

This bolt is a critical torque-load fastener. When installing this genuine factory part, you must tighten it firmly to the manufacturer’s exact specifications using a socket wrench. A loose bolt will quickly strip out the splines on your drive pulley, while over-tightening can easily snap the bolt head off inside the drive shaft.

Additionally, because the blue thread-locking compound activates immediately as the threads mesh, this bolt is engineered for a single-use application. If you ever unthread this bolt to service the bearings or direct-drive rotor, you cannot simply put it back in. The original adhesive seal is destroyed upon removal, and reuse risks the bolt backing out mid-spin, which can completely shatter your plastic outer tub shell. Always use a fresh, brand-new bolt for every reassembly!

Step-by-Step Replacement Guidelines:

1. Absolute Power Isolation: Unplug the washing machine’s electrical power cord from the wall outlet to eliminate all high-voltage shock hazards before working near the drive motor windings.

2. Remove the Rear Access Panel: Pull the washing machine out from the wall. Unthread the hex or Phillips head screws holding the metal rear cover plate to the frame, slide the plate off, and set it aside to expose the large circular direct-drive rotor motor casing.

3. Isolate the Motor Rotor: Use a socket wrench (typically 17mm or 19mm depending on your specific layout) to unthread the single center bolt holding the plastic/metal outer rotor dome to the shaft. Hold the drum stationary with your other hand to keep it from spinning as you break the torque. Carefully pull the heavy magnetic rotor dome straight backward off the shaft splines.

4. Locate and Extract the Flange Bolt: With the rotor removed, you will see the drive pulley connection assembly. If you are replacing a worn, loose, or stripped version of the DC60-40137A bolt, unthread it carefully. If the original bolt has snapped off flush inside the shaft due to an unbalanced load slam, you will need to use a reverse-thread screw extractor bit to back out the remaining threaded stud.

5. Install the New Fastener: Thoroughly clean any old crusty thread sealant out of the internal shaft tracking using a wire brush. Hand-thread the new genuine bolt into the center of the shaft to ensure it doesn’t cross-thread. Use your socket wrench to drive it completely flush, applying steady, firm pressure to fully activate the blue locking adhesive compound.

6. Reassemble and Curing Window: Slide the magnetic motor rotor dome back onto the splines, lock down the central rotor nut tightly, and fasten the rear sheet-metal cover back onto the cabinet frame. Let the machine sit idle for a minimum of 2 to 4 hours before running a load to allow the liquid thread locker to completely cure and harden.

Are you replacing this bolt today because your washer’s rear drive motor pulley has loosened up and started knocking, or did the original bolt physically snap off inside the drive shaft?
