Karcher Lock Washer - Torna...

Product details
This lock washer is a replacement for the Karcher Tornado CV30 floor machine, part K63431870.
Lock washers keep a bolted joint tight under vibration, which is a floor machine's constant condition during a shift. When one goes missing or loses its spring tension, the fastener it backs up works loose over time, and a joint that should stay tight starts to rattle or shift under load. On a commercial floor machine that runs for hours at a stretch, a loose fastener rarely stays a minor issue for long.
Small hardware like this is easy to overlook during a repair, but skipping it and reusing a fatigued washer is a common reason the same fastener works loose again a few weeks after service. Replacing it alongside whatever bolt or fastener it backs up is cheap insurance against a repeat callback.
- Fits: Karcher Tornado CV30 floor machine
- Part: Lock washer, part K63431870
- Function: Keeps a threaded fastener from backing out under vibration
- Tip: Replace lock washers as a set if the others on the same assembly show wear
Match the washer to the fastener it pairs with before reassembly, since lock washers come in more than one size and style.
