Looking to get the motor size on a Kenmore 158.14300. Looking to buy but want the big motor like then 14100 has. Thank you Kellie

It's a 90 Watt motor for both models - the 158 series uses the same motor...

Motor & Bracket #39963 (Replacement Motor) $59.95

Motor is 0.9A, 7000RPM, AC 110/125V, 90 watt, 50/60Hz
Fits models: 148 and 158 series where the motor is mounted internally or on the under side of the machine. Comes with bracket.
