The Washer (part# 7CM003) is a genuine Tacony OEM replacement part from the recovery and solution tank assembly of the Tornado Marathon SE 900 self-contained carpet extractor. It is the flat washer that distributes fastener load across the surface beneath the head or nut.
What the Washer does
A washer turns a point load into an area load. Without one, a screw head bears on a small ring of material and either digs into soft plastic or pulls through thin sheet, and in both cases the joint loses clamping force the moment the surface deforms. The washer also gives the head a smooth bearing surface so tightening torque goes into clamping rather than into scuffing the part.
When to replace the Washer (7CM003)
Replace it when it is dished, burred, or has picked up a groove from the fastener head, and whenever it is corroded. A washer that has cupped has already been overloaded and will not sit flat again.
Washer 7CM003 — fitment and installation notes
Use the specified washer rather than whatever is closest in the drawer, since outside diameter is what decides how far the load is spread. Fit it on the side the original came from, and where a fastener passes through plastic, check the plastic for the beginning of a crack before reassembling. Tacony builds the Tornado Marathon SE 900 and the Powr-Flite Prowler PFX900S on a single machine platform, so this component carries across both brands rather than belonging to either one. It is a shared Tacony component and may fit additional models beyond those listed — call us and we will confirm against your serial number.
