Product details
Part 73432A supplies the axle bushing used on the Sanitaire SC5815 commercial upright and its Eureka counterparts, also listed under the shorter catalog number 73432. Fitted around the wheel axle as a wear sleeve, its job is to hold the wheel tracking straight rather than letting it wobble against a bare, worn bore.
Because load on a rolling wheel comes mostly from one direction, the bushing wears oval instead of evenly. The first clue tends to be a wheel leaning slightly off vertical, followed by an intermittent squeak that fades in and out with load, until the upright starts pulling to one side no matter how carefully it is steered down a hallway. Since both bushings on a machine see roughly the same mileage, replacing just one usually means doing the same job again before long.
A new bushing restores a snug, quiet pivot and stops the slow sideways drift a worn bore causes over time. These bushings span a wide run of Eureka and Sanitaire commercial uprights built across several production years, so checking the exact model number against the list below is a faster way to confirm fit than judging by appearance alone.
- Part: 73432A axle bushing, also cataloged as 73432
- Function: the sleeve the wheel axle rotates inside
- Fits: Eureka and Sanitaire 2961AVZ, 2991AVZ, 2993AV, 2999AVZ, 3041, 4393A, C4571A, C5712A, C5712A-1, SC5713B, SC5713D, SC5745B, SC5815E, SC5845B and SC5845D
Change both bushings at once when one has gone oval, since the matching wheel is riding the same wear pattern.
