Tornado Spring Washer, Rear Assembly K73130020

This is the genuine spring washer (part# K73130020) used at one point in the rear assembly of the Tornado Strike TV190-W10-U, and on the Tornado Zephyr TV570-Q03-U. It is the second spring washer part number on this assembly and is not interchangeable with the other. Tacony does not carry it in the dealer catalogue, so it is call-for-price.

Compatible Models for the Spring Washer, Rear Assembly

• Tornado Strike TV190-W10-U cordless upright vacuum
• Tornado Zephyr TV570-Q03-U cordless upright vacuum

This part is not exclusive to the Strike. Tacony’s parts records list part# K73130020 against two machines — the Strike TV190-W10-U and the Zephyr TV570-Q03-U — which is why the title carries the brand rather than a single model name. One is fitted to the Strike.

What the Spring Washer, Rear Assembly does

The washer sits under its nut and keeps clamp load on the joint as the assembly settles and the compartment heats and cools. A single washer in a single place sounds trivial, but it is the one keeping that particular fastener from backing out, and a fastener backing out in the rear assembly does not stay a small problem for long.

Signs the Spring Washer, Rear Assembly needs replacing

Replace it on reassembly rather than waiting for a symptom. A washer that comes out flat has nothing left to give, and one that is cracked or distorted should not go back. If you find the matching fastener loose during a service, that is the washer telling you it is finished.

Fitting the Spring Washer, Rear Assembly

Fit a new washer under the nut as the joint goes back together, make sure it is sitting flat rather than perched on an edge, then start the nut by hand and tighten to snug. Do not over-torque a fastener running into a moulded part.

Frequently Asked Questions

Why is there no price shown?

Tacony does not list part# K73130020 in the dealer catalogue we buy from, so no published price exists. Call 763-535-0770 and we will confirm price and availability before ordering.

How is it different from the other spring washer on this assembly?

It is a different part number for a different position, and only one is fitted rather than three. Check the factory diagram on our Strike back-part page, or call us with your serial number, before ordering.

Can I re-use the old one?

We would not. A spring washer works by the tension it holds, and once it has been compressed and heat-cycled it has lost most of that.
