Washer X8858

The Washer (part# X8858) 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 a flat washer used under fasteners in the tank assembly.

What the Washer does

This washer distributes fastener load across the surface beneath it so the clamping force does not dig into plastic or thin sheet. In the tank assembly, where components are bolted to a moulded shell, the washer is what keeps a fastener from slowly working its way into the material and losing tension.

When to replace the Washer (X8858)

Replace it if it is bent, cupped, corroded, or has embedded itself into the surface below. A washer that has dished has already stopped doing its job; the joint it sits in will be loose and will keep loosening.

Washer X8858 — fitment and installation notes

Always refit a washer where one was originally used. Leaving it out — a common shortcut during a rushed rebuild — concentrates the load on the fastener face and is a reliable way to crack a plastic boss. 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.

• Tornado Marathon SE 900 — Model 98170
