This replacement metal motor pulley (part # 190086) is designed for Singer 221 Featherweight sewing machines equipped with metal-housing motors. The motor pulley is the grooved wheel that mounts on the motor shaft and drives the machine belt, transferring power from the motor to the handwheel and operating mechanism.

Specifications:

• Part Number: 190086
• Type: Replacement
• Material: All-metal construction
• Mounting: Allen set screw for secure attachment
• Shaft Compatibility: Standard 5/16 inch motor shaft diameter
• Motor Compatibility: Metal housing motors (such as CAT 3-110 and 3-120)

Machine Compatibility:

Fits Singer model: 221 Featherweight (with metal housing motors)

Important Compatibility Note:

This metal pulley is intended for motors with metal housings (such as CAT 3-110 and 3-120) and cannot be used to replace the Bakelite pulleys found on late-model motors with Bakelite housings. Please verify your motor housing type before ordering.

Function & Benefits:

The motor pulley is essential for power transmission from the motor to the machine. The all-metal construction provides durability and long-lasting performance, while the Allen set screw mounting ensures secure attachment to the motor shaft, preventing slippage during operation. Replace a worn, damaged, or missing motor pulley to restore proper belt drive and machine operation.

Installation Note:

Install the pulley on the motor shaft and secure it with the Allen set screw. Ensure the pulley is properly aligned with the handwheel pulley for correct belt tracking and smooth operation.
