When a machine's ridden a curb one too many times, or an arm's flexed past its design over the years, the resulting misalignment throws everything else off. The brush isn't quite level. The squeegee angle's a little off. The steering pulls. And it all traces back to a bent or worn structural piece.
This is the genuine Nilfisk Advance OEM SUPPORT INT PLAS F VAC MTR PKD, part number 9100001989, brand new in the box. Factory dimensions, factory materials, factory fit.
