Lock Washer 7CL002
$2.99
Genuine Tacony OEM lock washer (part# 7CL002) used on the Tornado Marathon SE 900 (Model 98170) and Powr-Flite Prowler PFX900S chassis. Sized for its own fastener, and not interchangeable with the other lock washers on the machine.
The Lock Washer (part# 7CL002) is a genuine Tacony OEM replacement part from the chassis assembly of the Tornado Marathon SE 900 self-contained carpet extractor. It is the spring lock washer specified for particular chassis fasteners on the machine.
What the Lock Washer does
Lock washers are sized to the bolt, not to the hole. One that is too large sits loose and cocks under the head so the spring load lands on one side, and one that is too small will not pass over the shank at all or gets forced on and cracked. Because they all look alike in a tray, keeping the specified size at the specified joint is most of what makes them work.
When to replace the Lock Washer (7CL002)
Replace it whenever the joint is opened, since the washer has already given up much of its spring, and immediately if it is flat, cracked, or the ends of the split have worn into steps. Corrosion between the coils is another reason to bin it rather than reuse it.
Lock Washer 7CL002 — fitment and installation notes
Place it against the turning part with a plain washer under it where the surface is soft, so the sharp ends bite the plain washer rather than the component. Do not mix sizes to make a stack work out, and never substitute a flat washer where a lock washer was specified. 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.
