Nut 7CN001
$2.99
Genuine Tacony OEM hex nut (part# 7CN001) used on the Tornado Marathon SE 900 (Model 98170) and Powr-Flite Prowler PFX900S chassis. A plain nut, which means whatever keeps it tight has to be fitted with it.
The Nut (part# 7CN001) is a genuine Tacony OEM replacement part from the chassis assembly of the Tornado Marathon SE 900 self-contained carpet extractor. It is the plain hex nut specified for chassis fastening points on the machine.
What the Nut does
A plain nut clamps and nothing else. It has no locking feature of its own, so the joint relies on the clamping tension in the bolt and on whatever locking hardware the design put with it, usually a lock washer or a second nut. Understanding that is what stops somebody leaving the washer out on reassembly and then wondering why one joint keeps rattling loose.
When to replace the Nut (7CN001)
Replace it when the thread is stripped, galled, or has been cut by an overtightened bolt, when the flats are rounded, or when corrosion has it seized. A nut that had to be split or ground off is replaced rather than dressed and reused.
Nut 7CN001 — fitment and installation notes
Refit whatever locking hardware came out with it, in the same order; a plain nut on its own in a vibrating joint will find its way loose. Hold the bolt head to stop it turning while tightening, so the load goes into the joint rather than into scuffing the parts as the bolt spins. 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.
