Tornado 98166
This is the parts home for the Tornado 98166, the 20-inch Marathon 800 self-contained carpet extractor built for 115-volt power with an 8-gallon tank. Everything below is organised the way the machine is actually built, so you can work from the assembly you are holding rather than guessing at a part number.
How Tornado 98166 parts are organised
The 98166 breaks down into thirteen sections on the factory drawings: the brush assembly, two chassis assemblies, the tank assembly, the control panel, the main assembly, two pump views, accessories and consumables, common replacement items, service parts, and two reference drawings covering the electrical system and the plumbing layout. Pick the section that matches the area you are repairing and the parts for that area are listed together with their callout numbers.
Which series do these Tornado 98166 parts fit?
The parts listed here are taken from the current Series F parts book. Older Series B through Series E Marathon 800 machines are built differently — they use different assemblies, not simply different part numbers, so a Series F listing is not a safe match for an early machine. If your machine is older, call us with the serial number and we will confirm the right part before you order.
The 8-gallon machine is not a 12-gallon machine
The Marathon 800 shares a good deal of hardware with the larger Marathon 1200, but the tank, bladder and frame are genuinely different components. The 8-gallon bladder is its own part, not a renumbered version of the 12-gallon one. Ordering across the two sizes by eye is the most common mistake on this family of machines.

Frequently Asked Questions
What Tornado 98166 parts can I buy here?
Everything the Series F parts book breaks out for the machine: the brush assembly, both chassis sheets, the solution and recovery tank assembly, the pump, the control panel, the plumbing and wiring references, the service-parts list, and the wands, tools, hoses and consumables that go with it. Each assembly has its own page so you are looking at one drawing at a time rather than a single long list.
How do I find the right part for my Tornado 98166?
Start from the assembly the part belongs to, then match the number printed beside it on that drawing to the row in the parts table. If you are between two similar items, read the description rather than going by the picture alone — several fasteners on these machines look identical and differ only in length or thread.
Will Tornado 98166 parts fit a Marathon 1200?
Some of the hardware will, but the major assemblies will not. The 98166 is the 8-gallon Marathon 800; the Marathon 1200 machines, 98168 and 98169, are 12-gallon and carry their own tank, bladder and frame assemblies. Always check by part number rather than assuming the two machines share a component.
How do I order Tornado 98166 parts or get help choosing?
Add the part you need to your cart from its own page, or call us at 763-535-0770 and we will confirm it against your machine first. Our staff at 5415 West Broadway, Crystal, MN 55428 has been servicing floor-care equipment since 1956, and if you have your serial number handy we can check it before anything ships.
