A lock washer keeps a fastener tight against vibration. On a machine with two motors and a brush turning continuously, that is not a nicety — a plain washer under a nut on this chassis will work loose eventually, and the fastener that backs off is rarely the one you would have predicted. Part number 32245 is the genuine OEM lock washer.

The mechanism is simple: the washer is sprung, so it keeps pushing the nut face against the thread flanks even after the joint has settled and lost a little of its clamping force. That is why it has to be replaced rather than reused. A lock washer that has been torqued flat once has spent its spring, and refitting it is the same as fitting a plain washer — it looks right and does nothing.
That is the single most useful thing on this page. If you have a joint that keeps needing retightening, the likeliest explanation is a lock washer that was reused during an earlier repair. They cost pennies and they are the cheapest insurance on the machine.
Judge a used one by its gap and its spring. A fresh washer has a visible step where the ends of the ring sit at different heights; one that has been crushed flat has no step. Corrosion is the other reason to replace: detergent reaches most of this chassis, and a washer that has pitted has lost section and therefore lost spring.
Order a handful rather than one. Lock washers are single-use by nature, they fall off during a strip-down, and a machine held up overnight waiting for a washer is a poor trade against keeping a few on the shelf.
Fit it directly under the nut with the mating faces clean, and torque to the correct figure rather than as hard as it will go — over-torquing crushes the spring on installation and gives you the same joint you were trying to fix. If the joint has a plain washer as well, that goes against the material and the lock washer goes against the nut.

Frequently Asked Questions
What Tornado machines does the lock washer 32245 fit?
It is used on the Tornado 98150 Mini-Marathon 425, 98150-ACE, 98150-PF and 98150LM Mini Marathon Lundmark extractors, the 98164 MWH-800, the 98166 and 98167 20″ Marathon 800, the 98168 12 Gallon Self Contained extractor and the 98168 20″ Marathon 1200 in all series. Call 763-535-0770 if your machine is not listed.
Can I reuse a lock washer?
No. It works by staying sprung, and one that has been torqued flat has spent its spring — refitting it is the same as fitting a plain washer. If a joint on your machine keeps needing retightening, a reused lock washer from an earlier repair is the likeliest explanation.
How do I tell a used lock washer from a fresh one?
Look at the step. A fresh washer has a visible offset where the two ends of the ring sit at different heights; one that has been crushed flat has none. Pitting from detergent is the other reason to replace it, because a washer that has lost section has lost spring.
