Complete Brush Assembly X9438

The Complete Brush Assembly (part# X9438) is the genuine OEM brush unit for the Tornado Marathon SE 900 self-contained carpet extractor and its Powr-Flite Prowler counterparts, supplied built up and ready to fit rather than as a box of individual components.

What the complete brush assembly covers

The brush section of this machine is the part that does the mechanical work: the brushroll agitates the pile while the solution is down and before the vacuum shoe lifts it, and everything around it exists to hold the roll straight, turn it at the right speed and keep solution out of the bearings. X9438 is that whole section as one part number — the 3″ x 18″ brushroll on its axle, the bearings, bearing shields and nylon spacers, the brush pulley and drive belt, and the motor and belt covers.

When to fit the complete assembly instead of individual parts

Twin City Vacuum stocks every component of this section separately, and for a single worn belt or a flattened brushroll the individual part is the right answer. The complete assembly earns its place when several wear items have failed together. A bearing that has run dry on a wet machine usually damages the axle it is sitting on, and once the axle, spacers, bearings and pulley are all on the list, one part number costs less in bench time than a rebuild and removes the risk of reassembling to the wrong end float.

Symptoms that point here

Rumble or squeal from the brush, a roll that will not spin freely with the belt removed, visible side play at the axle, uneven cleaning across the width of a pass, or belts that keep shredding. The last of those is the one most often misdiagnosed: a belt that fails repeatedly is normally reporting a seized or misaligned brush, not a weak belt.

Fitment

This assembly carries across both the Tornado and Powr-Flite ranges, which is why its name carries no brand. On the 98170 brush assembly sheet it is the not-shown item, catalogued alongside the individual components it contains.

Frequently Asked Questions

What is included in the complete brush assembly X9438?

X9438 is the brush assembly supplied built up rather than as loose components. It is the unit the whole brush sheet is drawn around: the 3 in. x 18 in. brushroll on its axle, the bearings, shields and nylon spacers at each end, the brush pulley, the drive belt and the motor and belt covers. Ordering it as one part replaces a rebuild made from twenty-odd individual numbers.

When is it better to fit X9438 than to rebuild the brush section?

When more than two or three of the wear items have gone at once, or when the bearings have run dry long enough to pick up the axle. Bearing failure on a brush that has been run wet rarely stops at the bearing; it takes the axle, the spacers and sometimes the pulley with it, and by the time those are all on the parts list the complete assembly costs less in labour and gets the machine back on the floor in one visit.

How do I know the brush assembly needs attention?

The usual signs are a brush that rumbles or squeals, that will not turn freely by hand with the belt off, that has visible side-to-side play at the axle, or that leaves an uneven clean across the width of a pass. A belt that keeps shredding is also usually reporting a seized or misaligned brush rather than a bad belt.

What models is the complete brush assembly (part# X9438) compatible with?

X9438 is used on three machines: the Tornado Marathon SE 900 (Model 98170), the Powr-Flite Prowler PFX900S, and the Powr-Flite PFX900SG. On the 98170 it is the not-shown item at the foot of the brush assembly sheet, which is how the factory catalogues an assembly that is sold complete alongside its own components.
