DESCRIPTION: Replacement mixer driver kit for 5500 series Oster Kitchen Centers. This is located in the mixer arm of the Oster Kitchen Center. Mixer driver is the round cup shaped piece with saw blade like teeth. It is held on by a c-clip.
DESCRIPTION: 5 cup, square top glass blender jar. Replaces Oster square top glass jars. Fits all Oster blender models using a 5 cup jar with a square top. Fits all Oster Kitchen Center models. This is the most common Oster jar type. All Kitchen Centers use this type of jar. This will fit all Oster blenders, but if your is a VERY old model (40 years old), using a 4 cup jar or a new model using a 6 cup jar, your lid will not fit and you may need to purchase the OS-060 lid and cap. THIS IS NOT A GENUINE OSTER PART. The INTERIOR of the top of the jar measures 4" x 4".
