(4.9/5 Stars) - Overall Rating from 54 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.

A lot of suction.
August 13, 2022
The recommended replacement motor was larger in diameter than my original OEM motor (7.2rdquo vs 5.7rdquo), but ii did fit, with some minor modifications to the screen enclosure that is installed over the motor. The motor works fine, and seems to have the same suction capability and noise level as the original OEM motor.
The central vac assembly is now in place, operating just fine, and my wife is happy.
