Tornado Shroud/Nozzle Mounting Bracket Weldment 19155

This weldment is the structure that carries both the brush shroud and the vacuum nozzle, and it is what sets the nozzle height above the carpet. That height is the single biggest factor in how much water the machine takes back out of the pile. Part number 19155 is the genuine OEM shroud and nozzle mounting bracket weldment for the MWH-800, Marathon 800 and Marathon 1200 extractors.

A bent weldment is the hidden cause behind a machine that leaves carpet too wet. The nozzle sits a fraction high at one end, the seal against the pile is lost along that edge, and the machine draws air instead of water there. Operators describe it as one side of the path drying slower than the other, which is a useful diagnostic because a worn nozzle or a tired vacuum motor produces an even result across the whole width.

Check it by setting the machine on a known-flat floor and sighting along the nozzle edge. It should sit parallel to the floor across its full width. Any twist, any lift at one end, or a shroud that will not close evenly against its gasket points at the weldment rather than the parts bolted to it.

These get bent by impact and by leverage. A machine dropped off a step lands on this structure, and a shroud forced shut over a jammed brush levers against it. Because it is a welded assembly rather than a simple bracket it does not bend back reliably — straightening a weldment tends to move the geometry somewhere else rather than restoring it.

Fitting is a bench job. Unplug the machine, tip and support it properly, photograph the positions of the shroud, nozzle and hinge before anything comes off, and transfer them to the new weldment in the same relationship. Then set the machine down on a flat floor and check the nozzle is parallel before the fasteners go fully tight.

Replace the shroud gasket and check the nozzle while the assembly is apart. Both are only accessible now, and a new weldment carrying a worn nozzle or a flattened gasket will not give you the pickup you are replacing it for.

Frequently Asked Questions

What Tornado machines does the mounting bracket weldment 19155 fit?

It is used on the Tornado 98164 MWH-800 8-gallon self-contained extractor, the 98166 and 98167 20″ Marathon 800, the 98168 12 Gallon Self Contained extractor and the 98168 20″ Marathon 1200 in all series. Call 763-535-0770 with your model number if you are not sure.

My machine leaves one side of the path wetter — is this the cause?

Very often. A weldment bent even slightly lifts the nozzle at one end, which breaks the seal against the pile along that edge so the machine draws air instead of water there. An uneven result across the width points at the weldment; an even one across the whole path points at the nozzle or the vacuum motor.

Can a bent weldment be straightened?

Not reliably. It is a welded assembly rather than a simple bracket, so straightening tends to move the geometry somewhere else rather than restoring it. Set the machine on a known-flat floor and sight along the nozzle edge: if it is not parallel to the floor across its full width, replace it.
