BigHead Washer Repair Kit — Shift Actuator, Pulley Clutch & 21" Drive Belt for Top‑Load Washers (OEM Fit, 3‑in‑1)

The BigHead 3-in-1 washer repair kit combines a W10913953 (49TYZ‑E120A1) shift actuator, a W10721967 pulley clutch assembly, and a 21" W10006384 drive belt to restore drive, agitation and spin function on compatible top‑load washers.

This complete replacement bundle gives you the core mechanical components that commonly fail in many Whirlpool, Maytag, Kenmore and related top‑load machines. Instead of hunting for separate parts, you get an actuator motor that times the transmission, a heavy‑duty clutch and pulley to transfer torque, plus a ribbed drive belt sized to factory specifications. The kit is engineered to match OEM fit and restore normal drum movement, agitation cycles and spin speeds when installed correctly.

How will this kit stop my washer from getting stuck in wash mode?

The W10913953 shift actuator is the component that tells the transmission which cycle to run. When the actuator fails, the transmission can remain in wash or fail to engage spin, leaving clothes soaking wet. Replacing the actuator often resolves cycle‑selection faults and intermittent agitation.

• Includes 49TYZ‑E120A1 compatible 50SM21‑1‑221B actuator (6‑pin, 120V AC, 3 RPM)
• Direct replacement for several OEM numbers to simplify selection
• Rebalances cycle timing so the transmission shifts properly

What fixes grinding noises and a drum that won’t spin even though the motor runs?

Those symptoms commonly point to a worn clutch or stripped pulley splines. The W10721967 pulley clutch kit rebuilds the drive interface between the motor/transmission and the tub. Installing a new clutch and cam assembly restores mechanical engagement and eliminates grinding or slipping under load.

• High‑strength steel gears and heat‑resistant polymers resist spline stripping
• Replaces common failing OEM clutch parts to restore proper engagement
• Reduces overheating and prevents burning smells from slipping components

Will a new belt stop slow rotation and sudden belt breakage?

The included W10006384 21" belt is manufactured from oil‑resistant, high‑elastic rubber with multi‑rib construction for superior grip. A degraded or stretched belt causes slow tub rotation, uneven movement and can snap mid‑cycle. Replacing the belt alongside the actuator and clutch ensures the entire drive system works together reliably.

• 21 inches long with 5 ribs and 4 grooves for OEM fit
• Improved elasticity and oil resistance to reduce slipping
• Works with the supplied pulley for correct tension and alignment

How difficult is installation and what basic steps should I follow?

Installation requires basic mechanical skills and common hand tools; the steps are straightforward if you follow safety precautions. Power and water must be disconnected first, and access is usually gained by tipping the washer to reach the bottom panel. Replace the actuator and clutch in sequence, fit the belt, then reassemble and test.

• Disconnect power/water and tape the lid; lay washer front‑side down
• Remove bottom panel to access actuator wiring and drive shaft
• Swap actuator, remove/install clutch and fit the 21" belt over pulleys

Who is this for: This BigHead repair kit is designed for DIYers, appliance technicians and maintenance professionals servicing compatible top‑load Whirlpool, Maytag, Kenmore, Amana, Crosley and Roper washers. It’s ideal when multiple drive components show wear — replacing actuator, clutch and belt together reduces repeat failures and cutting diagnosis time. Check your model number against the compatibility list before ordering to ensure proper fit.
