Thanks for your question.
Unfortunately, without the serial number of your unit we can't be certain if this Vita-Mix 891 Drive Socket will fit. Over the years Vita-Mix has made changes to their various models, and without a serial number they cannot be sure what replacement parts are needed, if your model is still under warranty, or if additional parts are needed.
Please give Vita-Mix a call directly, with your serial number on hand, at 1-800-848-2649.
