(4.9/5 Stars) - Overall Rating from 45 Users




The Ametek Lamb 117478 also known as 117478-12 Motor for central vacuums, blowers, and similar applications replaces all versions of the 117478 and 117478-12 motor used in all types of industries spanning many decades. Older model 117478-12 motors may not be marked properly with the motor number and some may have 11-7478-12 or just a 7478-12. We do not recommend rebuilding these types of motors due to cost and technical precision for proper performance and longevity.
