BigHead Washer Repair Kit — Shift Actuator, Pulley Clutch & 21" Drive Belt for Whirlpool/Maytag Top-Load Washers, OEM Fit

BigHead’s 3‑in‑1 washer repair kit combines the W10913953 shift actuator, W10721967 pulley clutch assembly, and a 21" W10006384 drive belt to replace the common failure points that stop top‑load washers from agitating, shifting, or spinning.

This kit was created to restore mechanical function quickly by replacing three parts that often fail together: the synchronous shift actuator that moves the gearcase between wash and spin, the clutch/pulley assembly that transmits motor torque to the tub, and the multi‑rib drive belt. All components are engineered to match OEM fit and many WHIRLPOOL, MAYTAG, KENMORE, AMANA, CROSLEY and ROPER machines, reducing the time and expense of sourcing parts individually. The set is ideal for the DIY technician or professional who wants one shipment that covers agitation, shifting and belt slipping problems.

How will this kit fix a washer that won’t agitate or switch cycles?

The W10913953 shift actuator in this kit is a synchronous AC motor assembly designed to move the washer’s transmission between wash and spin. Replacing a worn or burnt actuator commonly resolves stuck wash modes, buzzing during transitions, and error codes tied to shifting. Installation restores the mechanical linkage so the transmission engages properly.

• Replaces failed actuator models such as W10597177 and 49TYZ‑E120A1
• 50SM21‑1‑221B motor: 6‑pin, 120V AC, 3 RPM clockwise
• Stops buzzing and F7E5‑style shifting errors
• Reinforced ABS housing and metal core for durability

Why include a pulley clutch kit — what problems does it solve?

The W10721967 clutch and pulley assembly transfers rotation from the motor to the tub; when splines strip or the cam fails the drum can stop spinning even though the motor runs. Replacing the clutch assembly eliminates grinding, slipping under load, and overheating caused by worn spline teeth or damaged drive cams. A new clutch restores reliable torque transfer for spin cycles and heavy loads.

• High‑strength steel gears with heat‑resistant polymer cam
• Solves stripped spline symptoms and persistent grinding noises
• Prevents overheating and burning‑smell conditions
• Direct fit for many Whirlpool/Maytag family models

When should I change the drive belt and what does the included belt offer?

The 21" W10006384 drive belt is included to address slipping, slow rotation, or complete loss of motion caused by worn or broken belts. This belt uses oil‑resistant, high‑elastic rubber and a multi‑rib profile to maintain grip under load and resist stretching. Replacing the belt as part of this kit reduces the chance of immediate re‑failure after replacing actuator or clutch parts.

• 21 inches long with 5 ribs and 4 grooves for secure engagement
• Oil‑resistant rubber to avoid degradation in service
• Designed to prevent slipping and uneven drum movement
• Replaces WPW10006384 and equivalent OEM numbers

How difficult is installation and what are the basic steps?

Installation is a moderate DIY job that requires basic hand tools and safe handling practices. The kit ships with parts sized for an OEM fit; typical steps include powering down the washer, removing the bottom access panel, swapping the actuator wiring and housing, replacing the clutch/pulley on the drive shaft, and routing the new belt over the motor and tub pulleys. Follow safety steps and consult your model service sheet for exact fastener locations.

• Disconnect power and water first; work with the washer tipped safely on a protected surface
• Remove bottom panel to access the actuator and clutch area
• Swap actuator wiring harness, replace pulley/clutch assembly and install belt
• Reassemble panels and test a short, empty cycle to confirm proper operation

Who is this for? This BigHead 3‑in‑1 kit is intended for homeowners, appliance technicians, and independent repair shops who service top‑load Whirlpool‑family washers showing symptoms like no agitation, stuck in one cycle, grinding noises, slipping belts, or intermittent spin failures. It’s also a practical parts bundle for anyone who prefers replacing known wear items together to ensure a complete, reliable repair without multiple orders.
