Learn how to replace the collar on your KitchenAid blender jar with this step-by-step guide, including compatibility tips and common mistakes to avoid.

Quick Answer

To replace a KitchenAid blender jar collar, remove the old collar, align the new one with the jar's base, and press it into place—no tools needed. Verify the model compatibility (KSB565, KSB655, KSB755) before ordering.

Why the Collar Matters

The collar on your KitchenAid blender jar keeps the blade assembly sealed against the jar, preventing leaks and ensuring proper blending. Over time, it can crack, warp, or wear out, especially if the jar is frequently handled or cleaned in a dishwasher.

Replacing the collar is a simple DIY fix that can extend the life of your blender jar, saving you the cost of a whole new jar. However, it's important to note that the collar does not include a gasket, so you may need to purchase one separately if the gasket is worn.

Compatibility Check

Not all blender jar collars fit every model. The genuine KitchenAid replacement collar is designed specifically for models KSB565, KSB655, and KSB755. Before purchasing, check the model number on the base of your blender to ensure compatibility.

If your blender model is not listed, the collar may not fit securely, leading to leaks or improper blade operation. In that case, contact KitchenAid customer support for the correct part.

Step-by-Step Replacement Process

1. Unplug and Disassemble: Unplug the blender. Remove the jar from the base, then take off the lid and the blade assembly. Set the blade assembly aside carefully. Always work with the blender unplugged to avoid accidental starts.
2. Remove the Old Collar: Inspect the underside of the jar. The collar is usually a black ring that fits around the base. Gently pull it off, twisting slightly if needed. If it's stuck, use a flathead screwdriver to pry it loose, being careful not to scratch the jar. Check the old collar for cracks or warping to confirm it's the cause of any leaks.
3. Inspect the Gasket: Look at the gasket (the rubber ring) that sits between the jar and the blade assembly. If it's cracked, flattened, or missing, replace it before installing the new collar. The collar itself does not include a gasket. A worn gasket can cause leaks even with a new collar.
4. Install the New Collar: Align the new collar with the bottom of the jar, ensuring the opening matches the jar's shape. Press it firmly into place, working around the edges until it snaps on evenly. Make sure the collar sits flush and level—any gap could indicate misalignment.
5. Reassemble and Test: Place the gasket and blade assembly back into the jar, then screw the base onto the collar. Attach the jar to the blender base, plug it in, and run a quick test with water to check for leaks. If you notice any leaks, re-check the collar alignment and gasket condition.
