Springs are the parts nobody thinks about until one loses tension or breaks, and then something on the machine isn't sitting where it should — a lift, a return, a tension against a wear surface. And the funny thing about springs is that they usually fail gradually, so the machine gets a little wrong every day until somebody finally notices.
This is the genuine Nilfisk Advance OEM SPRING UPPER HOUSING, part number 56413828, brand new in the box. Factory tension matters — that's what the mechanism was designed around.
Cheap part, easy fix, high impact on how the machine feels to run.
