Engine Air Cleaner

1.Remove the air cleaner cover and foam filter element as shown in Figure 34.

2.Tap the paper filter element (Figure 32) several times on a hard surface to remove dirt, or blow compressed air [not exceeding 30 psi (207 kPa, 2.1 kgf/cm2)] through the filter element from the air cleaner case side. NEVER brush off dirt. Brushing will force dirt into the fibers. Replace the paper filter element if it is excessively dirty.

3.Clean foam element in warm, soapy water or nonflam- mablesolvent. Rinseand dry thoroughly.Dip the element in clean engine oil and completely squeeze out the excess oil from the element before installing.
