Retainer Ring B475-1900

The Retainer Ring (part# B475-1900) is a shared Tacony OEM part found on 26 models from 3 Tacony brands (Tornado, Riccar and Simplicity). This is a shared Tacony OEM part fitted across Tornado, Riccar and Simplicity models — see the full Compatible Models list below.

On the Tornado Roam / 97300 / 97300C, retainer rings seat in a groove to keep bearings, bushings, or shaft parts from moving along the shaft. Part# B475-1900 holds its component captured against the constant load and vibration of commercial use so shafts stay located and rotating parts run true.

Replace the retainer ring if it is sprung, distorted, or missing, or any time you remove one during service, since they lose tension when disturbed. A weak or missing ring lets the retained part shift or fall out, which can cause noise, play, or a failed assembly. They are inexpensive and best renewed rather than reused.

Frequently Asked Questions

What does the retainer ring do inside the agitator?

The retainer ring (part# B475-1900) is a spring clip that snaps into a groove to lock a bearing or shaft component so it cannot walk out of position while the brushroll spins. It is small but load-bearing: it is what keeps the captured part from creeping sideways under vibration.

Is it normal to replace the retainer ring whenever I service the agitator?

Yes — a retainer ring loses tension once it has been sprung off, so best practice is to fit a fresh B475-1900 rather than reuse a clip that may no longer grip its groove. A ring that has lost its spring can pop free and let the part it holds slide loose.

Does the retainer ring come as a single clip?

It is sold individually so you can replace just the clip that has fatigued or been lost during disassembly, instead of buying a larger sub-assembly. Keeping a spare on hand is handy because these rings are easy to launch across the bench during service.

Which models take the retainer ring (part# B475-1900)?

It fits the Tornado Roam 97300 and 97300C and the shared Riccar, Simplicity and CleanMax platform uprights listed in the Compatible Models section above.
