Beschreibung
Zusammenfassung:	A restriction indicator for an air cleaner of an internal combustion engine. A bellows-type diaphragm is biased toward a retracted position by a first end of a compression spring. A calibration wheel threadingly engaging the housing supports a second end of the compression spring, such that the restriction indicator can be calibrated by rotation of the calibration wheel. An end of the compression spring is seated on a slanted seating surface so that a plunger is pushed off-center to engage a latch and lock the restriction indicator.
