Tornado Tank Frame Member 11″ 19316

The tank frame is a welded cage that holds the solution and recovery tanks square inside the machine, and this is the 11-inch cross member in it. Part number 19316 is the genuine OEM member for the Marathon 800 and Marathon 1200 extractors. Order by the measured length, not by position — the frame uses several members of different lengths and they are not interchangeable. It also fits the Tornado 98167 20″ Marathon 800 carpet extractor (8 Gallon, 230V).

Cross members are what stop the frame racking. A full recovery tank is heavy, and every time the machine is tipped, bumped up a kerb or loaded into a van, that weight tries to push the frame into a parallelogram. The cross members resist it. When one fails, the frame goes slightly out of square and the tanks stop seating flat, which shows up as a lid gasket that will not seal evenly and suction that has dropped for no visible reason.

Look for the failure at the welds rather than in the middle of the tube. A cross member almost never bends along its length; it cracks where it is joined, because that is where the load concentrates. Clean the area and look closely at the weld fillets, particularly on the underside where corrosion hides them. A hairline at a weld toe is the early stage of a member that will let go.

Test the frame rather than the part. With the tanks out, push the top of the frame sideways by hand: a sound frame barely moves. Any noticeable flex, or a frame that springs back slowly rather than immediately, means something in the cage is no longer carrying load. Then work along the members to find which one.

Measure before you order. The frame uses members at 11 and 12 inches plus the side pieces, and they look similar enough that ordering by eye is how people end up with the wrong one. Take the length off the old part with a rule rather than relying on where it sat.

Fit the replacement with the tanks out and the machine supported. Get the frame square before you tighten anything — a member fitted into a racked frame holds the rack permanently. Set the tanks in afterwards and check they sit flat and that the lid gasket compresses evenly all round before the machine goes back to work.

Frequently Asked Questions

What Tornado machines does the 11-inch tank frame member 19316 fit?

It is used on the Tornado 98166 and 98167 20″ Marathon 800 carpet extractors, the Tornado 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.

How do I know which frame member has failed?

Take the tanks out and push the top of the frame sideways by hand. A sound frame barely moves; noticeable flex means something in the cage is no longer carrying load. Then work along the members looking at the welds rather than the middle of the tubes — they crack at the joints, not along their length.

How do I make sure I order the right member?

Measure the old part with a rule. The frame uses members at 11 and 12 inches plus the side pieces, and they look similar enough that ordering by eye or by remembered position is the usual way people end up with the wrong one.
