Tornado Wheel Shaft Bushing 11077

The wheel shaft bushing is the bearing surface between the wheel and the axle. It carries the working weight of a full machine, turns every time the machine is moved, and lives in the splash zone where solution reaches it constantly. Part number 11077 is the genuine OEM bushing, used on the Marathon 800 and Marathon 1200 extractors and on the High Speed Glazer machines.

A worn bushing announces itself as a wobble. Lift the machine so the wheel is off the floor, grip the wheel at top and bottom and rock it: a sound bushing gives almost no movement. Play there means the bushing has worn oval, and an oval bushing lets the wheel lean, which drags the machine off a straight line and makes the operator fight it all day.

The second symptom is noise and effort. A bushing that has picked up grit or corroded turns stiffly, so the wheel scuffs rather than rolls. Machines with one stiff wheel pull to that side, which people usually blame on a bent axle. Check both before ordering either — and if the axle is bent, replace the bushings with it, because a bent axle wears them unevenly and fitting a straight axle into oval bushings just transfers the problem.

These are cheap and they are a pair. Always replace both sides together: they do identical work, so a bushing worn enough to need replacing has a twin close behind, and the machine has to be lifted and supported either way.

The thing worth protecting against is grit. Sand and carpet grit reach the bushing and lap it every time the machine rolls. Rinsing the wheel area at the end of a job rather than letting slurry dry in makes a real difference to how long a set lasts.

Fit with the machine tipped and properly supported — a full machine on its side is heavy enough to do damage, so support it rather than balancing it. Clean the axle before the new bushing goes on, check the axle for scoring while it is exposed, and confirm the machine rolls straight on a flat floor before putting it back to work.

Frequently Asked Questions

It is used on the Tornado 98166 and 98167 20″ Marathon 800, the 98168 12 Gallon Self Contained extractor, the 98168 20″ Marathon 1200 in all series, the 98169 20″ Marathon 1200, and the 98440 and 98445 20″ High Speed Glazer machines. Call 763-535-0770 with your model number if you are not sure.

How do I know the wheel bushing is worn?

Lift the machine so the wheel is clear of the floor, grip the wheel top and bottom and rock it. A sound bushing gives almost no movement. Play means the bushing has worn oval, which lets the wheel lean and drags the machine off a straight line.

My machine pulls to one side — bushing or axle?

Check both. A stiff or corroded bushing scuffs rather than rolls and pulls the machine that way, and a bent axle does the same. If the axle is bent, replace the bushings with it: a bent axle wears them unevenly, and fitting a straight axle into oval bushings just moves the problem along.
