Screw 10-32 x 5/8″ X9118
$2.99
Genuine OEM 10-32 x 5/8 inch screw (part# X9118) used in the Tornado Marathon SE 900 (Model 98170) and Powr-Flite Prowler PFX900S brush assembly. A fine thread, so it belongs in metal, not a plastic boss.
The Screw 10-32 x 5/8″ (part# X9118) is a genuine OEM replacement part from the brush assembly of the Tornado Marathon SE 900 self-contained carpet extractor. It is the specified 10-32 fine thread machine screw at 5/8 inch length used at brush assembly fastening points. It also fits the Tornado 98168 20″ Marathon 1200 carpet extractor (12 Gallon 115V), Series E, F and P.
What the Screw 10-32 x 5/8″ does
Fine threads hold torque well and resist vibration, which is exactly what a fastener on a driven assembly needs, but they achieve that by having more, shallower threads and that makes them easy to cross-thread and easy to strip. Fitting the 10-32 where the drawing calls for one, and the coarse 10-24 where it calls for that, is what keeps a tapped hole usable across the life of the machine.
When to replace the Screw 10-32 x 5/8″ (X9118)
Replace it when the recess is chewed, when the thread is galled, dragged or stripped, or when corrosion has it binding. A fine thread that has been cross-threaded once will feel notchy on the way in and should be replaced along with checking the hole it goes into.
Screw X9118 — fitment and installation notes
Always start it by hand and feel it pick up the existing thread before using a driver. Never substitute a coarse 10-24 of the same length, since it will feel like it is tightening while it destroys the tapped hole, and tighten to a firm seat rather than leaning on it. The Tornado Marathon SE 900 and the Powr-Flite Prowler PFX900S are built on a single machine platform, so this component carries across both brands rather than belonging to either one. It is a shared component and may fit additional models beyond those listed — call us and we will confirm against your serial number.
