SEBO Chassis for the 350 Mechanical Upright — Light Gray

The chassis is the molded base a SEBO 350 Mechanical is built around. The axle, wheels, release pedal and cleaning head all hang off it, so a hairline crack or a broken mounting boss shows up as a machine that leans, rattles, or will not hold its recline. Part 50444HGER is that base in light gray, supplied as the factory component rather than a repaired original.

Damage to a chassis produces a scatter of symptoms that look unrelated until you trace them back. A boss that has snapped lets a panel drum against its neighbour. A frame that has taken a hard drop puts the head slightly out of square, so the belt tracks toward one flange and the bearing blocks load unevenly. A cracked pedal mount means the machine no longer stays where it is parked. Chasing each of those individually rarely settles the machine down, because the fault they share is the base beneath them. Every mounting point on a new chassis sits where the original had it, so the hardware you carry across bolts straight back in and the upright stands square again.

Work through the transfer methodically, keeping fasteners grouped by location and photographing wiring runs before anything is unplugged. The parts that mount to this chassis on the 350 Mechanical include power head cover 50431GSAM at position 100, bumper 50314HG at 103, brush roller release 50433HGER at 108, front bottom plate 50434HGER at 114, axle clamp 2849 at 115, brush roller 50471ER at 121, rubbing plate 2869HG at 124 and axle with wheel 50348HGER at 125. Rear bottom plate 50311HGER completes the underside.
