An air cleaner includes a housing and an access cover. The internal volume of the housing can be reached through an opening in a side wall of the housing. A filter element having fluted filter media is removable and replaceable from the air cleaner. The housing is constructed and arranged to cam the element into sealing engagement with the housing. The access cover includes structure to help support and ensure proper seating of the filter element within the housing. A method of installing the filter element in the air cleaner includes sliding a portion of the filter element against a slide surface in the housing. A method of servicing an air cleaner includes tilting the filter element against a tilt surface in the housing to release a seal between the filter element and the housing. The filter element can have a handle to assist in servicing of the air cleaner. The housing can have a window to allow visual inspection of the internal component of the housing and to determine visually whether a filter element is installed therein.

The present disclosure relates to a restriction indicator for an air cleaner system of an internal combustion engine. The restriction indicator includes a housing divided into first and second chambers by a diaphragm. A signal member is connected to the diaphragm. The signal member is moveable along an axis between a reset position and a first indicator position, and defines an axial opening within which a first retaining shoulder is located. A guide member is provided for guiding the signal member as the signal member is moved between the reset position and the first axial position. A retaining member is provided for retaining the signal member in the first indicator position. The retaining member extends within the axial opening of the signal member and includes at least two fingers that project radially outward from the axis. The fingers are configured to engage the first retaining shoulder to retain the signal member in the first indicator position. The restriction indicator further includes a reset button for deflecting the fingers radially inward to disengage the fingers from the first retaining shoulder thereby allowing the signal member to be returned to the reset position. The reset button includes a portion that extends within the axial opening of the signal member between the retaining member and the signal member.

Restriction indicator

Filter for engine

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.
