Kirby Rear Bearing Finger/T...
$11.99
Product details
This 10-pack of Kirby OEM rear bearing finger springs (Part #314990A) fits Kirby uprights from the 1CB and later. Each thrust spring applies axial preload that keeps the rear motor bearing seated firmly in its housing.
When these springs weaken or break, the rear bearing can float in its seat, which brings on motor noise, vibration, and premature bearing failure. Replacing the springs restores steady preload so the bearing stays put and the motor runs quiet.
- Fits: Kirby 1CB and later uprights
- Part: OEM #314990A, sold as a 10-pack
- Function: Preloads and seats the rear motor bearing
- Tip: Keep a pack on hand as routine motor-service stock
Each spring installs during a motor bearing service. Verify your Kirby model before ordering so the spring matches the bearing seat.
