Tornado Strike Lock Piece Kit, 4 Sets K28842730

The Lock Piece Kit (part# K28842730) supplies four sets of the small locking pieces that retain the Tornado Strike’s glide sole. It is a kit rather than a single item because these pieces are replaced as a group — if one has failed the others have done the same service and are close behind.

Compatible Models for the Lock Piece Kit, 4 Sets

• Tornado Strike Cordless Upright Vacuum — Model TV190-W10-U

This is a Strike-only component: Tacony’s parts records list the Tornado Strike TV190-W10-U as the single machine that takes part# K28842730, so there is no cross-model substitution to worry about when you order it.

What the Lock Piece Kit, 4 Sets does

The sole is the part of the machine that takes the most abuse, and it has to come off for cleaning and for brushroll access. Locking pieces let that happen without tools while still holding the sole tight enough that it does not shift under the drag of carpet. When they lose their grip the sole moves fractionally on every pass, which chews its mounting points and lets the head ride at the wrong height.

Signs the Lock Piece Kit, 4 Sets needs replacing

Replace the set when the sole can be rocked by hand with everything fitted, when a lock piece no longer clicks positively into place, when one is cracked or has lost a tab, or when the sole has started coming loose in service. If you find one broken, fit the whole kit rather than a single piece — that is what the kit is for.

Fitting the Lock Piece Kit, 4 Sets

Work with the head inverted on a bench. Remove the sole, take out the old lock pieces and clear the recesses of packed fibre and grit, which is usually what stopped them seating properly. Fit the new pieces, refit the sole, and check by hand that it is held with no rock or lift at any corner before the head goes back on the machine.

Twin City Vacuum has been selling and servicing Tornado equipment since 1956. You can browse the rest of the machine on our Tornado Strike parts pages, and the manufacturer publishes specifications at tornadovac.com.
