Nut X9169

The Nut (part# X9169) is a genuine Tacony OEM replacement part from the brush assembly of the Tornado Marathon SE 900 self-contained carpet extractor. It is the nut specified for particular fastening points within the brush assembly.

What the Nut does

On a driven assembly the nut is half of a clamped joint that never stops being shaken. What keeps it tight is the tension stored in the bolt when it was correctly torqued, plus whatever locking hardware the design specified alongside it. Change either half of that arrangement and the joint will loosen, usually slowly enough that the cause is forgotten by the time the symptom appears.

When to replace the Nut (X9169)

Replace it when the thread is stripped, galled or corroded, when the flats are rounded from being turned with the wrong tool, or when it has been split or heated to get it off. A nut that binds partway down a clean thread has been damaged and does not go back on.

Nut X9169 — fitment and installation notes

Refit the locking hardware that came out with it, in the same order, and hold the bolt so the load goes into the joint rather than into scuffing the parts. Clean the threads first, since fibre and dried chemistry pack into this area, and check the assembly turns freely by hand before running the machine. 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.
