(5) Install oil cup, making sure that retaining spring clips are fully engaged in lip of oil cup and hold oil cup securely to cleaner body.
(6) Oil bath air cleaners on earlier models are of “round” type, oil cup being secured to body with a metal clamp band and thumb screw. When oil cup is removed on this type of cleaner, the baffle plate will come out with the cup. Make sure that baffle plate is correctly installed and that gasket is in place when installing cup.
c. Maintenance ([fig. 47]). The rectangular‐type oil bath air cleaner is provided with two filter elements, retained in filter body by means of the baffle plate. If daily check reveals excessive accumulation of dirt and grit in oil and cup, filter elements must be removed and cleaned. NOTE: Check several times daily under extremely dusty or sandy conditions.
(1) Hold oil cup with one hand and release (unlatch) oil cup retaining spring clips; remove cup.
(2) Unscrew baffle plate thumb screw and remove baffle plate.
(3) Filter elements may “bind” in cleaner body. If so, rap side of body with hand to loosen them; or, if necessary, withdraw elements from body with pliers or a hooked wire.
