The Motor Shaft Seal is an OEM component for Whirlpool stand mixers. It is a mechanical component that forms a perimeter around the motor shaft opening, protecting internal parts from debris intrusion. Maintaining an airtight seal prevents contaminants from disrupting operations.

Symptoms of a damaged motor shaft seal include:

• Flour, wet ingredients, or dust leakage at the motor housing connection  
• Premature motor failure due to abrasive particle penetration
• Grinding or scraping noises emanating from the shaft area during use
• Reduced mixing power and inability to smoothly knead doughs

Causes usually relate to typical wear over long-term, repeated use of the mixer. Constant rotational motion against the sealing material results in damage like cracking or splits compromising its integrity.

This OEM Whirlpool replacement restores protective shielding for the motor. Compatible brands are KitchenAid, Sunbeam, Hamilton Beach, and some Kenmore stand mixers.

The Lift Arm is an OEM part for Whirlpool stand mixers. It's a part that facilitates the movement of the mixing bowl, allowing for easy attachment and removal, as well as adjustment of the bowl height during mixing.

Causes of a bad part can vary from normal wear and tear due to frequent use, improper adjustment or handling causing stress or damage to the arm, to accidental impact that may bend or break the arm.

Symptoms of a bad Lift Arm include:

• Difficulty in adjusting the bowl height, leading to uneven mixing.
• The bowl not securing properly or wobbling during operation.
• Excessive wear or damage visible on the arm, affecting its function.

Symptoms of a bad washer include:

• Excessive noise and vibration from the gear assembly
• Premature failure of gears or other components
• Reduced power transmission and mixing performance

This OEM replacement is also compatible with Maytag, Whirlpool, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.

The KN256WW 5 Quart KitchenAid Wire Whip is an OEM part for Kitchenaid stand mixers. This wire whip is essential for incorporating air into ingredients, making it perfect for whipping cream, egg whites, and mixing light, fluffy batters.

This small flat washer is used as a hardware spacer in Whirlpool appliances. It distributes clamping force and helps maintain proper alignment and smooth movement where a screw, bolt, or pin secures components. Exact placement varies by model.

• Distributes load to protect mating surfaces from damage
• Acts as a spacer/shim to set correct clearance
• Helps reduce friction and metal-to-metal noise
• Common symptoms of a worn or missing washer: loose or misaligned parts, scraping/squeaking, or difficulty keeping a fastener tight

• Disconnect power and shut off water supply before servicing
• Support the assembly and note the original washer order and placement during disassembly
• Reinstall the washer in the same position/orientation as the original
• Tighten hardware snugly; do not overtighten to avoid deforming the washer

This small hardware washer fits under a screw or nut to spread clamping force and protect the mounting surface. Replacing a worn or missing washer helps keep assemblies secure and can reduce rattling, vibration, and premature wear.

• Distributes load under a fastener to prevent pull-through and surface damage
• Maintains proper spacing and alignment between parts in an assembly
• Helps resist loosening from vibration when tightened correctly
• Symptoms of wear/failure: fastener won't stay tight, rattling or wobble, visible deformation of the old washer

• Disconnect power; shut off water supply if working on a water-bearing appliance
• Access and support the assembly; note the stack order/orientation of any spacers or bushings
• Install the new washer and reinstall the fastener; tighten snugly—do not overtighten
• Confirm proper alignment and operation before closing up panels
