Whirlpool Dryer Drum Drive Belt (Part # 661570V)

Restore smooth, consistent tumbling to your laundry routine with this Genuine OEM Whirlpool Dryer Drum Drive Belt. This factory-certified replacement rubber belt (Part # 661570V, which officially incorporates factory-certified design parameters like 661570 and WP661570) is the primary mechanical link wrapping entirely around the outer perimeter of your dryer drum, connecting it directly to the motor pulley and idler tension arm.

Manufactured directly by Whirlpool, this heavy-duty belt features a multi-grooved internal design constructed from high-grade, fiber-reinforced rubber compounds. It is specifically engineered to resist extreme heat, frictional wear, and stretching under the weight of heavy, wet clothes. Over years of handling regular drying cycles, the rubber naturally dries out, frays, or snaps. If your dryer motor hums when you hit start but the drum refuses to spin, or if you hear a loud slipping sound mid-cycle, your drive belt has likely broken or slipped off its tracks.

Quick Info:

• Compatibility: Precision engineered for Whirlpool, Maytag, Kenmore, Amana, Roper, Estate, KitchenAid, and Crosley gas and electric dryers utilizing a standard perimeter drum wrap layout.

• Specifications: Standard 4-rib (3-groove) structural configuration engineered for balanced mechanical energy displacement.

• Fixes Common Issues: Resolves a dryer drum that won’t turn or spin, loud squeaking or rhythmic thumping noises during operation, a humming motor with zero drum movement, or clothing coming out damp due to improper drum traction.

• Difficulty: Novice to Intermediate. A highly accessible DIY project requiring about 15 to 25 minutes and basic hand tools.

Pro Tip: When threading this new belt over your drum, its physical orientation is critical for proper mechanical traction. Always install the belt with the ribbed (grooved) side facing flat down against the metal dryer drum, and the smooth side facing outward away from it. When you wrap it down around the lower motor pulley at the bottom of the cabinet floor, the grooved side must align perfectly into the matching grooved tracks of the brass motor shaft gear, while the smooth backside of the belt rides flush against the plastic wheel of the spring-loaded idler pulley arm.

Step-by-Step Replacement Guidelines:

1. Safety Power Isolation: You must completely unplug the dryer’s heavy 240V power cord or shut off the main dual-pole house circuit breaker to eliminate all shock hazards before dismantling the cabinet frame.

2. Access the Internal Shroud: Slide a rigid putty knife horizontally into the front top seam between the main cabinet face and the top lid to release the hidden spring clips, lifting the top panel upward. Unplug the plastic wire harness leading to the door safety switch, unbolt the main front bulkhead wall, and lift the assembly off its bottom alignment hooks.

3. Position the New Belt: Loop the fresh, genuine belt completely around the center section of the dryer drum barrel like a hoop, ensuring the ribbed side is facing the metal skin. Use the belt as a makeshift sling handle to lift the drum slightly and guide the front edge of the drum onto its front supporting rollers or glides.

4. Lock the Tension: Reach your hands underneath the bottom floor of the drum into the lower right quadrant near the motor assembly. Pull the spring-loaded metal idler pulley arm to compress the spring, thread the lower loop of the belt underneath the idler wheel, and hook the final loop securely onto the grooved teeth of the motor shaft pulley.

5. Track Verification: Slowly rotate the drum barrel by hand a few full turns to verify the belt tracks are perfectly straight without twisting or jumping tracks before reassembling the cabinet.

Are you overhauling your dryer today because your original belt snapped completely in half, or has the rubber stretched out and started slipping under a heavy load of clothes?
