Lock Washer 07870

The Lock Washer (part# 07870) is a genuine Tacony OEM split lock washer for the Tornado CK 3030 wide-area vacuum (Model 93030). E, F and G.

Like all split lock washers it is a single turn of hardened spring steel with offset ends. As the fastener is tightened the coil is flattened and stores tension, keeping the thread loaded even if the joint settles slightly; the two sharp cut ends dig into the nut face and the surface beneath to resist the nut backing off. On a machine with two motors running continuously, that resistance to rotation is the difference between a fastening that stays tight for years and one that needs checking every service.

Treat it as a one-use part. A washer that has been flattened once has lost most of its spring and its biting edges are already dulled, so refitting the old one puts a plain washer in a position that was specified to have a locking one. Replace any washer that lies flat when free, that has rounded edges, or that is cracked at the split.
