What the Tooth Lock Washer does

The teeth of this lock washer dig into both the fastener and the part it clamps as the joint is tightened, resisting the vibration that would otherwise let an ordinary fastener back off. On a machine that runs a wide agitator and two motors, that constant vibration works fasteners loose over time, so toothed lock washers are used at joints that must stay put between services.

Signs the Tooth Lock Washer needs replacing

Replace the tooth lock washer if its teeth are flattened, worn, or corroded so it no longer bites, or whenever the joint it secures has been taken apart. A fastener that keeps loosening on its own is a sign its lock washer has lost its grip and should be renewed with a fresh one that can bite into the surfaces again.

Installation and fit

Place the new 11007 tooth lock washer under the fastener so its teeth contact both the fastener and the mating surface, then tighten so the teeth set into the metal. Renew rather than reuse a flattened washer. Twin City Vacuum has sold and serviced Tacony equipment since 1956, and every part is sourced directly from Tacony.

Frequently Asked Questions

What does the Tooth Lock Washer do on the CleanMax CM-WAV?

It is a #10 internal-tooth lock washer. The teeth bite into the underside of the fastener head and into the mating surface, so the joint resists the vibration that would slowly back a plain washer off. On a wide-area vacuum or a carpet extractor the brush and motor put a constant low-level vibration through every bracket, which is exactly the condition a plain washer cannot hold against.

Its teeth bite into the fastener and the mating surface to resist the vibration that would otherwise let the fastener back off, keeping the joint tight between services.

How do I know if my CM-WAV tooth lock washer needs replacing?

Look at the teeth. A washer that has been torqued down and released has flattened teeth and will not bite again, and one that is dished, discoloured from heat or visibly corroded has lost its spring. The practical answer is that a tooth lock washer is a single-use item: if you have taken the joint apart, fit a new one rather than re-using the old.

Replace it if the teeth are flattened, worn, or corroded so it no longer bites, or whenever the joint has been apart. A fastener that keeps loosening is the sign.
