SEBO Rubber Motor Mount for the 1843/2 Suction Motor — 370 Comfort and Electronic 370

A new buzz coming from the base of a 370 after years of service is usually down to rubber. Part 1822 is the rubber mount that cradles the 1843/2 suction motor in the SEBO 370 Comfort and Electronic 370.

Heat cycling gradually hardens the compound until it takes a permanent set or tears through. A mount in that condition no longer isolates anything, so the motor drums its vibration straight into the plastics around it. That is louder to live with, and it is hard on every fixing nearby — screws that once stayed put start backing out, and mouldings that were never designed to be shaken develop cracks around their bosses. The sound is characteristic: a healthy machine hums, while one on a collapsed mount buzzes and changes note as it is tilted.

Rubber is the material here, and its condition is judged by feel rather than by looks. A mount that has gone hard and glassy is finished even if it is still in one piece.

Judging a mount takes seconds. Press a thumb into the rubber and let go: sound material springs back, while a mount that has hardened simply holds the dent or feels glassy and dead under pressure. Anyone searching for a SEBO 370 motor mount, a 1843/2 motor cushion or an Electronic 370 vibration mount is looking at part 1822.

Genuine SEBO from an authorized dealer, usually shipping in 2–5 business days. Renew the mount whenever the motor comes out, not only when it has visibly failed, because the labour is already spent and a tired mount undoes much of the benefit of a fresh motor. Unplug the machine before opening the motor bay, and note how the old mount is oriented so the new one goes back the same way round.
