Solutions to a Seized Up Blade Assembly Unit on a Blendtec / KTec Blender Container February 05 2016
The blade assembly cutting assembly in Blendtec jars (Wildside and Fourside containers) are permanently fix installed in the jar. The ball bearings or bushing can seize up due to water entering the blade assembly housing / bearing housing. The seals sometimes wear out. When the blending assembly is not turning appropriately any more, blending creates smoke and some oil or debris could mix with the smoothie content.
Normally, like in Vita Mix type blending containers, blade assembly units can be removed from the jar and replaced. With Blendtec jars the only solution is to throw the jar away and buy a new jar, if your blender warranty is no longer valid. And there is really no reason why one should be upset.

See Video about changing out the Container, and what type of container might work the best with the objective to never repeat this expensive problem again.
Please note, even then, with any jar or blade regardless from which brand, that being Vita Mix, Waring, Hamilton Beach, JTC, Optimum, etc (and Blendtec), seals can wear out and blades can seize up. It is important to recognize the problem early so no further damage is caused to the blender motor itself.
