Tornado Nylon Nut 17883

Nylon rather than steel, and on a machine that circulates detergent all day that is a deliberate choice rather than a cost saving. Part number 17883 is the genuine OEM nylon nut for the MWH-800, Marathon 800 and Marathon 1200 extractors.

The reason for nylon here is that it does not corrode and it does not gall. A steel nut on a steel stud in standing solution seizes, and the next person to service the joint either rounds it off or twists the stud. A nylon nut comes off years later the same way it went on, which is worth a great deal more than the few cents the material saves.

The trade-off is torque. Nylon has a fraction of the strength of steel and no reserve at all — it does not yield and warn you, it strips. Tighten to firm by hand and stop. If a joint here feels like it needs more than that, something else is wrong: a missing washer, a warped face, or the wrong fastener from a previous repair.

Treat it as single use. The thread deforms slightly on every tightening, and a nylon nut that has been on and off three times no longer grips the way it did. It costs very little against the nuisance of a joint that will not stay tight.

Heat is the other thing to watch. Nylon near a hot motor housing or a heated component embrittles over time, and an embrittled nut cracks rather than loosens — sometimes without any sign until it falls off. If yours has gone chalky or crazed on the surface, replace it and check why it is running warm.

Do not substitute a steel nut of the same thread because it is what is to hand. It will fit and it will tighten, and the next person to open that joint will pay for it.

Frequently Asked Questions

What Tornado machines does the nylon nut 17883 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.

Why nylon instead of steel?

Because it does not corrode or gall. A steel nut on a steel stud in standing detergent seizes, and the next person to service that joint either rounds it off or twists the stud. A nylon nut comes off years later the way it went on, which is worth far more than the material saves.

How tight should it be?

Firm by hand and no more. Nylon has no reserve — it does not yield and warn you, it strips. If the joint feels like it needs more force, something else is wrong: a missing washer, a warped face, or the wrong fastener left by an earlier repair.
