Tornado Nut, Rear Assembly K73110020

This is the genuine Tacony nut (part# K73110020) used at a single point in the rear assembly of the Tornado Strike TV190-W10-U. It is the second of two nut part numbers on this assembly, and it is not interchangeable with the other. Tacony does not list it in the dealer catalogue, so it is call-for-price.

Compatible Models for the Nut, Rear Assembly

• Tornado Strike TV190-W10-U cordless upright vacuum
• Tornado Tempest TV400-W26-U cordless upright vacuum
• Tornado Zephyr TV570-Q03-U cordless upright vacuum

This part is shared across Tacony’s cordless range. Its parts records list part# K73110020 against three machines — the Strike TV190-W10-U, the Tempest TV400-W26-U and the Zephyr TV570-Q03-U — so the title carries the brand rather than one model name. One is fitted to the Strike.

What the Nut, Rear Assembly does

It fastens its joint in the rear assembly, paired with the spring washer the factory specifies for that position. The reason two similar nuts carry different part numbers on one assembly is that the joints are not the same — different thread, different clamp requirement, or different mating part. Substituting one for the other is the kind of shortcut that produces a joint that feels right and is not.

Signs the Nut, Rear Assembly needs replacing

Order a replacement when the original has been lost, rounded at the flats, cross-threaded or corroded, or when the joint has been apart enough times that the fastener no longer grips confidently. Because only one is fitted, losing it during a repair stops the job, which is the usual reason people order one.

Fitting the Nut, Rear Assembly

Start it by hand and let it find the thread before applying any torque. Fit the spring washer the assembly calls for rather than re-using a flattened one, and tighten to snug. Check the joint is holding the moulded parts together squarely before moving on.

Frequently Asked Questions

Why is there no price on this listing?

Tacony does not carry part# K73110020 in the dealer catalogue, so there is no published price for us to quote. Call 763-535-0770 and we will confirm price and lead time.

How is this different from the other Strike nut?

It is a different part number used at a different point in the rear assembly, and only one is fitted rather than three. They are not interchangeable — check the factory diagram or call us with your serial number.

Can I use a nut from a hardware store?

We would not recommend it. The thread, material and head form are specified for the joint, and a nut that merely fits is not the same as a nut that clamps correctly and stays put on a machine that vibrates all day.
