This is the factory chassis sheet for the Marathon SE 900 — the main chassis, the wheels and their hardware, the solution pump and its brass plumbing, the solenoid valve, the vacuum shoe and tube, the access door with its hinges and gasket, and the labels and grommets that finish the frame. The table below follows the drawing’s own callout numbers from 1 to 53, so the row number and the bubble on the sheet are always the same number. Hover any dot to read the part name before you click it. Twin City Vacuum has been selling and servicing Tornado equipment since 1956 — call 763-535-0770 or stop by 5415 West Broadway, Crystal, MN 55428.
Tornado 98170 chassis parts – Frequently Asked Questions
How do I find the right Tornado 98170 chassis part?
Work from the diagram. Nearly every numbered bubble on the factory drawing carries a red dot beside it; hover a dot to read the part name and number, and click it to open that part. The table below lists the same callouts in order, so you can also work down the numbers. Five callouts show a phone number instead of a price because we are still listing them, and callout 53 is the upholstery kit, which the factory lists without bubbling it on the drawing. Call 763-535-0770 for any of those.
Why do some callout numbers have more than one dot?
Because the factory drawing bubbles the same part in more than one place. Callout 29, the hose clamp, appears three times, and callouts 30 and 47 appear twice each, once for every position the part is fitted. Every one of those dots opens the same product, so you can click whichever instance you are looking at.
Which chassis parts fail first on a Marathon SE 900?
The pump and the solution plumbing do the most work. The braided hose, the hose barbs and the single-ear clamps harden and seep before anything else, and a weeping fitting looks exactly like a failing pump while costing a fraction as much to put right. Check the hose run end to end before you condemn the pump at callout 10. The wheels, the hinges and the door gasket are the other wear items.
Does this sheet cover every chassis revision of the 98170?
This page is transcribed from the 7 Aug 2023 chassis assembly sheet for the Tornado Marathon SE 900 (Model 98170). A few chassis parts changed mid-production, so read the model and serial number off the plate on the back of the machine and call 763-535-0770 — we will confirm the part against your serial number before it ships.
