SEBO Suction Motor Sound In...

Product details
A SEBO 370 that has grown noticeably louder without losing any suction is usually a machine missing the padding around its motor. Part 1851 is the acoustic insulation that sits in the suction motor bay of the 370 COMFORT and the ELECTRONIC 370, wrapping the motor so the noise it generates is absorbed inside the housing rather than radiating out through the body panels.
Insulation is a consumable in everything but name. Years of heat and vibration pack the material down, harden it and break it up at the edges, and once it has lost its loft it stops damping anything. It is also the item most often left out of a rebuild: a motor gets changed, the old padding crumbles as it comes away, and the machine goes back together without it. The result is a vacuum that sounds coarse and resonant instead of smooth, frequently with a new buzz coming up through the handle. Fresh insulation brings the running note back to what the upright had when it was new.
Both machines that take this insulation are covered by the one number, the 370 COMFORT and the ELECTRONIC 370, and there is no colour option or handed version to choose between. Ordering comes down to confirming the model on the data plate. Because the part is soft rather than structural, a machine will run for years without it and simply sound wrong the whole time, which is why it is worth checking during a service rather than waiting for something to fail.
- Fits: SEBO 370 COMFORT and ELECTRONIC 370

The compartment has to be open to reach it, which makes this a natural companion to any motor work. Check the motor mount, the shroud and the seals around the bay while everything is exposed.
