Tornado Strain Relief 19929

The strain relief is the bushing where the power cord enters the machine. Its job is to make sure that when the cord is pulled — and it is pulled constantly — the load goes into the bushing and the outer jacket rather than into the terminals inside. Part number 19929 is the genuine OEM strain relief. This is the 230-volt part, fitted to the Tornado 98167 20″ Marathon 800 carpet extractor (8 Gallon, 230V).

This part is shared across a wide run of machines. On the Marathon 1200 family it is fitted to:

• Tornado 98168 12 Gallon Self Contained Carpet Extractor
• Tornado 98168 20″ Marathon 1200 Carpet Extractor (12 Gallon, 115V) — all series
• Fits many other machines — call 763-535-0770 and we will confirm fitment for your machine.
• Tornado 98167 20″ Marathon 800 (8 Gallon, 230V)

This is the highest-value safety part on the machine per dollar spent. Without an intact strain relief, every tug on the cord is transmitted directly to the internal connections. They loosen, then arc, then overheat. A machine whose cord can be pulled and felt moving at the terminals inside should not be used until this is fixed.

Check it in two ways. Look at the bushing itself for cracking, for a piece missing, or for a relief that is loose in its hole. Then take hold of the cord just outside the machine and pull firmly: the cord should not move relative to the housing at all. Any movement means the relief has failed or was never properly seated.

Look at the cord where it passes through at the same time. A failed relief and a damaged cord usually arrive together, because once the bushing stops gripping, the jacket flexes at a single point and eventually splits there. If you can see conductor insulation through the outer jacket, the cord is a replacement as well and the machine is not safe to run.

Detergent and flexing age it. The material hardens over years, and a hardened relief cracks rather than gripping — often around the cord, so it looks present while doing nothing.

Fit with the machine unplugged at the wall. Seat the relief fully so it locks into the housing, check that it grips the cord jacket rather than the conductors, and confirm with a firm pull before closing the machine up. Never run a machine with the relief left out “temporarily”.

Frequently Asked Questions

What machines does the strain relief 19929 fit?

It is fitted to the Tornado 98168 12 Gallon Self Contained carpet extractor and the 98168 20″ Marathon 1200 in all series, and it is shared across many other machines. Call 763-535-0770 with your model and serial number and we will confirm fitment before you order It also fits the Tornado 98167 Marathon 800 (8 Gallon, 230V).

Why does a strain relief matter so much?

Because without it, every tug on the cord goes straight into the terminals inside. They loosen, then arc, then overheat. It is the highest-value safety part on the machine per dollar spent, and a machine whose cord can be felt moving at the terminals should not be used until it is fixed.

How do I test whether mine has failed?

Look for cracking, a missing piece, or a relief loose in its hole. Then take the cord just outside the machine and pull firmly — it should not move relative to the housing at all. Check the cord jacket at the same point too: a failed relief and a split jacket usually arrive together.
