Kenmore Caster Unit - Canis...
$17.99
Product details
The caster unit is the small swivel wheel assembly that carries a canister vacuum's body across the floor, and it takes nearly all of the wear a canister absorbs. The body gets towed by the hose across every floor transition in the house, and the caster is what keeps it rolling smoothly instead of skidding or catching.
This is part number 4370691, sold as a caster unit for the Kenmore 21814, 81714, BC4002, BC4026, and BC4027, and it is also listed for the Titan T8000. A worn caster announces itself in specific ways: the body drags rather than rolls, it veers toward one side when the hose pulls it, it tips on sharp turns, or a cracked wheel starts scraping a groove into hardwood instead of spinning across it.
Casters on canister vacuums see more abuse than most people realize, since the body is dragged rather than pushed, which loads the wheel at odd angles it was never quite designed for. A caster that spins freely but wobbles side to side on its stem is partway through the same failure as one that has already seized, and it is worth swapping before the stem cracks and drops the caster out of its socket entirely.
