Older model 116311 motors may not be marked properly with the motor number and some may have 11-6311 or just a 6311.

I bought this to replace my Tristar motor which was 35 years old. The motor fit perfectly but my only complaint is it's about 20% less powerful than the original. I guess I can't complain as the Lamb Ametek motor was $300 cheaper. I used to sell Tristar vacuums in 1987 and don't ask why, but still have my kit to testdemo the motor.
