It also serves the ELECTRONIC 370, which shares the same power-head architecture, and it is not one of the general chassis washers used elsewhere on SEBO machines.\u003c\/p\u003e\u003cp\u003eInside a power head the washer sits under a fastener in an assembly that is turning, loaded and constantly shaken by the brush roll, so a flat, undamaged bearing face is worth more here than almost anywhere else on the machine. A washer that has cupped, worn thin or picked up a burr lets its screw settle a fraction, clamping force drops away, and the bracket it was holding begins to move against the housing. That movement is what turns a five-minute washer change into a worn boss and a much longer repair.\u003c\/p\u003e\u003cp\u003eThe tell-tales are a power head that has developed a knock, a fixing that will not stay tight through a single job, or visible polishing where a bracket has been fretting. Ordering the ET-C1 by number takes the guesswork out of matching an unmarked washer by eye, which matters because a power head carries several similar-looking rings in different specifications. SEBO's own designation on this one, ET-C1, is the whole point: it identifies the washer by the assembly it belongs to rather than by a generic bore size.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSEBO part 0155 — washer ET-C1\u003c\/li\u003e\n\u003cli\u003eFits the SEBO ELECTRONIC 370 and the ET-C power heads\u003c\/li\u003e\n\u003cli\u003ePower-head specific — not the general 3.2 or 4.3 chassis washer\u003c\/li\u003e\n\u003cli\u003ePack: one washer.
